Complete checklist for manual upgrades to 10gR2
PREREQUISITES
=============
+ Install Oracle 10g Release 2 in a new Oracle Home.
+ Install the latest available patchset from Metalink.
+ Install the latest available Critical Patch Update.
Note 290738.1 Oracle Critical Patch Update Program General FAQ
+ Either take a cold or hot backup for your database.
+ Make sure to take a backup of Oracle Home and Central Inventory.
Central inventory can be located by the contents of oraInst.loc files.
"oraInst.loc" is available in the following locations on various platforms
/var/opt/oracle/oraInst.loc -- Solaris
/etc/oraInst.loc -- other operating systems
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\inst_loc -- On windows Platform.
+ Verify kernel parameters are set according to the 10gR2 Installation Guide.
+ Verify that all O/S packages and patches are installed as per the Installation Guide.
COMPATIBILITY MATRIX
====================
+ Minimum Version of the database that can be directly upgraded to Oracle 10g Release 2
8.1.7.4 -> 10.2.X.X.X
9.0.1.4 or 9.0.1.5 -> 10.2.X.X.X
9.2.0.4 or higher -> 10.2.X.X.X

STEPS FOR UPGRADING THE DATABASE TO 10G RELEASE 2
=================================================
Preparing to Upgrade
--------------------
In this section all the steps need to be performed to the previous version of Oracle.
Please note that the database must be running in normal mode in the old release.
Step 1:
~~~~~~~
Log in to the system as the owner of the new 10gR2 ORACLE_HOME and copy the following
files from the 10gR2 ORACLE_HOME/rdbms/admin directory to a directory outside of the Oracle home,
such as the /tmp directory on your system:
ORACLE_HOME/rdbms/admin/utlu102i.sql
ORACLE_HOME/rdbms/admin/utltzuv2.sql
Make a note of the new location of these files.
Step 2:
~~~~~~~
Change to the temporary directory that you copied files to in Step 1.
Start SQL*Plus and connect to the database instance as a user with SYSDBA
privileges. Then run and spool the utlu102i.sql file.
sqlplus '/as sysdba'
SQL> spool Database_Info.log
SQL> @utlu102i.sql
SQL> spool off
Then, check the spool file and examine the output of the upgrade information
tool. The sections which follow, describe the output of the Upgrade
Information Tool (utlu102i.sql).
Database:
This section displays global database information about the current database such
as the database name, release number, and compatibility level. A warning is displayed
if the COMPATIBLE initialization parameter needs to be adjusted before the database is
upgraded.
Logfiles:
This section displays a list of redo log files in the current database whose size is
less than 4 MB. For each log file, the file name, group number, and recommended size
is displayed. New files of at least 4 MB (preferably 10 MB) need to be created in the
current database. Any redo log files less than 4 MB must be dropped before the database
is upgraded.
Tablespaces:
This section displays a list of tablespaces in the current database. For each tablespace,
the tablespace name and minimum required size is displayed. In addition, a message is
displayed if the tablespace is adequate for the upgrade. If the tablespace does not have
enough free space, then space must be added to the tablespace in the current database.
Tablespace adjustments need to be made before the database is upgraded.
Update Parameters:
This section displays a list of initialization parameters in the parameter file of the
current database that must be adjusted before the database is upgraded. The adjustments
need to be made to the parameter file after it is copied to the new Oracle Database 10g
release.
Deprecated Parameters:
This section displays a list of initialization parameters in the parameter file of the
current database that are deprecated in the new Oracle Database 10g release.
Obsolete Parameters:
This section displays a list of initialization parameters in the parameter file of the
current database that are obsolete in the new Oracle Database 10g release. Obsolete
initialization parameters need to be removed from the parameter file before the
database is upgraded.
Components:
This section displays a list of database components in the new Oracle Database 10g release
that will be upgraded or installed when the current database is upgraded.
Miscellaneous Warnings:
This section provides warnings about specific situations that may require attention before
and/or after the upgrade.
SYSAUX Tablespace:
This section displays the minimum required size for the SYSAUX tablespace, which is required
in Oracle Database 10g. The SYSAUX tablespace must be created after the new Oracle Database
10g release is started and BEFORE the upgrade scripts are invoked.
Step 3:
~~~~~~~
Check for the deprecated CONNECT Role
After upgrading to 10gR2, the CONNECT role will only have the CREATE SESSION
privilege; the other privileges granted to the CONNECT role in earlier releases will be
revoked during the upgrade. To identify which users and roles in your database are granted
the CONNECT role, use the following query:
SELECT grantee FROM dba_role_privs
WHERE granted_role = 'CONNECT' and
grantee NOT IN (
'SYS', 'OUTLN', 'SYSTEM', 'CTXSYS', 'DBSNMP',
'LOGSTDBY_ADMINISTRATOR', 'ORDSYS',
'ORDPLUGINS', 'OEM_MONITOR', 'WKSYS', 'WKPROXY',
'WK_TEST', 'WKUSER', 'MDSYS', 'LBACSYS', 'DMSYS',
'WMSYS', 'OLAPDBA', 'OLAPSVR', 'OLAP_USER',
'OLAPSYS', 'EXFSYS', 'SYSMAN', 'MDDATA',
'SI_INFORMTN_SCHEMA', 'XDB', 'ODM');
If users or roles require privileges other than CREATE SESSION, then grant
the specific required privileges prior to upgrading. The upgrade scripts
adjust the privilegesfor the Oracle-supplied users.
In Oracle 9.2.x and 10.1.x CONNECT role includes the following privileges:
SELECT GRANTEE,PRIVILEGE FROM DBA_SYS_PRIVS
WHERE GRANTEE='CONNECT'
GRANTEE PRIVILEGE
------------------------------ ---------------------------
CONNECT CREATE VIEW
CONNECT CREATE TABLE
CONNECT ALTER SESSION
CONNECT CREATE CLUSTER
CONNECT CREATE SESSION
CONNECT CREATE SYNONYM
CONNECT CREATE SEQUENCE
CONNECT CREATE DATABASE LINK
In Oracle 10.2 the CONNECT role only includes CREATE SESSION privilege.
Step 4:
~~~~~~~
Create the script for dblink incase of downgrade of the database.
During the upgrade to 10gR2, any passwords in database links will be encrypted.
To downgrade back to the original release, all of the database links with encrypted passwords
must be dropped prior to the downgrade. Consequently, the database links will not exist in
the downgraded database. If you anticipate a requirement to be able to downgrade back to your
original release, then save the information about affected database links from the SYS.LINK$ table,
so that you can recreate the database links after the downgrade.
Following script can be used to construct the dblink.
SELECT
'create '||DECODE(U.NAME,'PUBLIC','public ')||'database link '||CHR(10)
||DECODE(U.NAME,'PUBLIC',Null, U.NAME||'.')|| L.NAME||chr(10)
||'connect to ' || L.USERID || ' identified by '''
||L.PASSWORD||''' using ''' || L.host || ''''
||chr(10)||';' TEXT
FROM sys.link$ L,
sys.user$ U
WHERE L.OWNER# = U.USER# ;
Step 5:
~~~~~~~
Check for the TIMESTAMP WITH TIMEZONE Datatype. Please this step is only required for the 10gR1
The may affect existing data of TIMESTAMP WITH TIME ZONE datatype.
For example, if users enter TIMESTAMP '2003-02-17 09:00:00 America/Sao_Paulo',
we convert the data to UTC based on the transition rules in the time zone file
and store them on the disk. So '2003-02-17 11:00:00' along with the time zone id
for 'America/Sao_Paulo' is stored because the offset for this particular time is '-02:00'.
Now the transition rules are modified and the offset for this particular
time is changed to '-03:00'. when users retrieve the data, they will get
'2003-02-17 08:00:00 America/Sao_Paulo'. There is one hour difference compared to the
original value.
Change to the temporary directory that you copied files to in Step 1.
Start SQL*Plus and connect to the database instance as a user with SYSDBA
privileges. Then run and spool the utltzuv2.sql file.
$ sqlplus '/as sysdba'
SQL> spool TimeZone_Info.log
SQL> @utltzuv2.sql
SQL> spool off
If the utltzuv2.sql script identifies columns with time zone data affected
by a database upgrade, then there two ways of solving this problem
Solution
--------
create tables with the time zone information in character format
(for example, TO_CHAR(column, 'YYYY-MM-DD HH24.MI.SSXFF TZR'), and recreate
the TIMESTAMP data from these tables after the upgrade.
For example, user scott has a table tztab:
create table tztab(x number primary key, y timestamp with time zone);
insert into tztab values(1, timestamp '');
Before upgrade, you can create a table tztab_back, note column y here is
defined as VARCHAR2 to preserve the original value.
create table tztab_back(x number primary key, y varchar2(256));
insert into tztab_back select x,
to_char(y, 'YYYY-MM-DD HH24.MI.SSXFF TZR') from tztab;
After upgrade, you need update the data in the table tztab using the value in tztab_back.
update tztab t set t.y = (select to_timestamp_tz(t1.y,
'YYYY-MM-DD HH24.MI.SSXFF TZR') from tztab_back t1 where t.x=t1.x);
Step 6:
~~~~~~~
Starting in Oracle 9i the National Characterset (NLS_NCHAR_CHARACTERSET) will be
limited to UTF8 and AL16UTF16.
For more details refer to The National Character Set in Oracle 9i and 10g
Any other NLS_NCHAR_CHARACTERSET will no longer be supported.
When upgrading to 10g the value of NLS_NCHAR_CHARACTERSET is based
on value currently used in the Oracle8 version.
If the NLS_NCHAR_CHARACTERSET is UTF8 then new it will stay UTF8.
In all other cases the NLS_NCHAR_CHARACTERSET is changed to AL16UTF16
and -if used- N-type data (= data in columns using NCHAR, NVARCHAR2 orNCLOB )
may need to be converted.
The change itself is done in step 38 by running the upgrade script.
If you are NOT using N-type columns *for user data* then simply go to next step.
No further action required.
( so if: select distinct OWNER, TABLE_NAME from DBA_TAB_COLUMNS where
DATA_TYPE in ('NCHAR','NVARCHAR2', 'NCLOB') and OWNER not in
('SYS','SYSTEM'); returns no rows, go to next step.)
If you have N-type columns *for user data* then check:
SQL> select * from nls_database_parameters where parameter
='NLS_NCHAR_CHARACTERSET';
If you are using N-type columns AND your National Characterset
is UTF8 or is in the following list:
JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED
then also simply go to point next step.
The conversion of the user data itself will then be done in step 37
If you are using N-type columns AND your National Characterset is NOT
UTF8 or NOT in the following list:
JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED
(your current NLS_NCHAR_CHARACTERSET is for example US7ASCII, WE8ISO8859P1, CL8MSWIN1251 ...)
then you have to:
* change the tables to use CHAR, VARCHAR2 or CLOB instead the N-type
or
* use export/import the table(s) containing N-type columns
and truncate those tables before migrating to 9i.
The recommended NLS_LANG during export is simply the NLS_CHARACTERSET,
not the NLS_NCHAR_CHARACTERSET
Step 7:
~~~~~~~
When upgrading to Oracle Database 10g, optimizer statistics are collected
for dictionary tables that lack statistics. This statistics collection can
be time consuming for databases with a large number of dictionary tables,
but statistics gathering only occurs for those tables that lack statistics
or are significantly changed during the upgrade.
To decrease the amount of downtime incurred when collecting statistics,
you can collect statistics prior to performing the actual database upgrade.
As of Oracle Database 10g Release 10.1, Oracle recommends that you use
the DBMS_STATS.GATHER_DICTIONARY_STATS procedure to gather these statistics.
You can enter the following:
$ sqlplus '/as sysdba'
SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;
In Case of the 9.0.1 or 9.2.0 release, then you should use the
DBMS_STATS.GATHER_SCHEMA_STATS procedure to gather statistics.
Backup the existing statistics as follow
$ sqlplus '/as sysdba'
SQL>spool sdict
SQL>grant analyze any to sys;
SQL>exec dbms_stats.create_stat_table('SYS','dictstattab');
SQL>exec dbms_stats.export_schema_stats('WMSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('MDSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('CTXSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('XDB','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('WKSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('LBACSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('OLAPSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('DMSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('ODM','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('ORDSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('ORDPLUGINS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('SI_INFORMTN_SCHEMA','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('OUTLN','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('DBSNMP','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('SYSTEM','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('SYS','dictstattab',statown => 'SYS');
SQL>spool off
This data is useful if you want to revert back the statistics
For example, the following PL/SQL subprograms import the statistics for the SYS schema after
deleting the existing statistics:
exec dbms_stats.delete_schema_stats('SYS');
exec dbms_stats.import_schema_stats('SYS','dictstattab');
To gather statistics run this script, connect to the database AS SYSDBA using SQL*Plus.
$ sqlplus '/as sysdba'
SQL>spool gdict
SQL>grant analyze any to sys;
SQL>exec dbms_stats.gather_schema_stats('WMSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('MDSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('CTXSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('XDB',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('WKSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('LBACSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('OLAPSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('DMSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('ODM',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('ORDSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('ORDPLUGINS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('SI_INFORMTN_SCHEMA',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('OUTLN',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('DBSNMP',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('SYSTEM',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('SYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
- method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>spool off
Step 8:
~~~~~~~
Check for invalid objects invalid objects.
spool invalid_pre.lst
select substr(owner,1,12) owner,
substr(object_name,1,30) object,
substr(object_type,1,30) type, status from
dba_objects where status <>'VALID';
spool off
Run the following script and then requery invalid objects:
This script must be run as a user with SYSDBA privs using SQL*Plus:
$ cd $ORACLE_HOME/rdbms/admin
$ sqlplus '/as sysdba'
SQL> @utlrp.sql
This last query will return a list of all objects that cannot be recompiled
before the upgrade in the file 'invalid_pre.lst'
Step 9:
~~~~~~~~
Check for corruption in the dictionary, use the following commands in sqlplus
connected as sys:
Set verify off
Set space 0
Set line 120
Set heading off
Set feedback off
Set pages 1000
Spool analyze.sql
Select 'Analyze cluster "'||cluster_name||'" validate structure cascade;'
from dba_clusters
where owner='SYS'
union
Select 'Analyze table "'||table_name||'" validate structure cascade;'
from dba_tables
where owner='SYS' and partitioned='NO' and (iot_type='IOT' or iot_type is NULL)
union
Select 'Analyze table "'||table_name||'" validate structure cascade into invalid_rows;'
from dba_tables
where owner='SYS' and partitioned='YES';
spool off
This creates a script called analyze.sql.
Now execute the following steps.
$ sqlplus '/as sysdba'
SQL> @$ORACLE_HOME/rdbms/admin/utlvalid.sql
SQL> @analyze.sql
This script (analyze.sql) should not return any errors.
Step 10:
~~~~~~~~
Ensure that all Snapshot refreshes are successfully completed, and that
replication is stopped.
$ sqlplus '/as sysdba'
SQL> select distinct(trunc(last_refresh)) from dba_snapshot_refresh_times;
Step 11:
~~~~~~~~
Stop the listener for the database:
$ lsnrctl
LSNRCTL> stop
Ensure no files need media recovery:
$ sqlplus '/ as sysdba'
SQL> select * from v$recover_file;
This should return no rows.
Step 12:
~~~~~~~~
Ensure no files are in backup mode:
SQL> select * from v$backup where status!='NOT ACTIVE';
This should return no rows.
Step 13:
~~~~~~~~
Resolve any outstanding unresolved distributed transaction:
SQL> select * from dba_2pc_pending;
If this returns rows you should do the following:
SQL> select local_tran_id from dba_2pc_pending;
SQL> execute dbms_transaction.purge_lost_db_entry('');
SQL> commit;
Step 14:
~~~~~~~~
Disable all batch and cron jobs.
Step 15:
~~~~~~~~
Ensure the users sys and system have 'system' as their default tablespace.
SQL> select username, default_tablespace from dba_users
where username in ('SYS','SYSTEM');
To modify use:
SQL> alter user sys default tablespace SYSTEM;
SQL> alter user system default tablespace SYSTEM;
Step 16:
~~~~~~~~
Optionally ensure the aud$ is in the system tablespace when auditing is enabled.
SQL> select tablespace_name from dba_tables where table_name='AUD$';
Step 17:
~~~~~~~~
Note down where all control files are located.
SQL> select * from v$controlfile;
Step 18:
~~~~~~~~
Shutdown the database
$ sqlplus '/as sysdba'
SQL> shutdown immediate;
Step 19:
~~~~~~~~
PERFORM a Full cold backup!!!!!!!
You can either do this by manually copying the files or
sign on to RMAN:
$rman "target / nocatalog"
And issue the following RMAN commands:
RUN
{
ALLOCATE CHANNEL chan_name TYPE DISK;
BACKUP DATABASE FORMAT 'some_backup_directory%U' TAG before_upgrade;
BACKUP CURRENT CONTROLFILE TO 'save_controlfile_location';
}
Upgrading to the New Oracle Database 10g Release 2
--------------------------------------------------
Step 20:
~~~~~~~~
Update the init.ora file:
- Make a backup of the init.ora file.
- Comment out obsoleted parameters(list in appendix A).
- Change all deprecated parameters(list in appendix B).
- Set the COMPATIBLE initialization parameter to an appropriate value. If you are
upgrading from 8.1.7.4 then set the COMPATIBLE parameter to 9.2.0 until after the
upgrade has been completed successfully. If you are upgrading from 9.2.0 or 10.1.0
then leave the COMPATIBLE parameter set to it's current value until the upgrade
has been completed successfully. This will avoid any unnecessary ORA-942 errors
from being reported in SMON trace files during the upgrade (because the upgrade
is looking for 10.2 objects that have not yet been created)
- If you have set the parameter NLS_LENGTH_SEMANTICS to CHAR, change the value
to BYTE during the upgrade.
- Verify that the parameter DB_DOMAIN is set properly.
- Make sure the PGA_AGGREGATE_TARGET initialization parameter is set to
at least 24 MB.
- Ensure that the SHARED_POOL_SIZE and the LARGE_POOL_SIZE are at least 150Mb.
Please alos the check the "KNOWN ISSUES" section
- Make sure the JAVA_POOL_SIZE initialization parameter is set to at least 150 MB.
- Ensure there is a value for DB_BLOCK_SIZE
- On Windows operating systems, change the BACKGROUND_DUMP_DEST and USER_DUMP_DEST
initialization parameters that point to RDBMS80 or any other environment variable
to point to the following directories instead:
BACKGROUND_DUMP_DEST to ORACLE_BASE\oradata\DB_NAME
and
USER_DUMP_DEST to ORACLE_BASE\oradata\DB_NAME\archive
- Comment out any existing AQ_TM_PROCESSES parameter setting, and enter a new one
that explicitly sets AQ_TM_PROCESSES=0 for the duration of the upgrade
- Make sure all path names in the parameter file are fully specified. You should not
have relative path names in the parameter file.
- If you are using a cluster database, set the parameter CLUSTER_DATABASE=FALSE
during the upgrade.
- If you are upgrading a cluster database, then modify the initdb_name.ora
file in the same way that you modified the parameter file.
Step 21 :
~~~~~~~~~
Check for adequate freespace on archive log destination file systems.
Step 22 :
~~~~~~~~~
Ensure the NLS_LANG variable is set correctly:
$ env | grep $NLS_LANG
Step 23:
~~~~~~~~
If needed copy the SQL*Net files like (listener.ora,tnsnames.ora etc)
to the new location (when no TNS_ADMIN env. Parameter is used)
$ cp $OLD_ORACLE_HOME/network/admin/*.ora /network/admin
Step 24:
~~~~~~~~
If your Operating system is Windows NT, delete your services
With the ORADIM of your old oracle version.
Stop the OracleServiceSID Oracle service of the database you are upgrading,
where SID is the instance name. For example, if your SID is ORCL, then enter
the following at a command prompt:
C:\> NET STOP OracleServiceORCL
For Oracle 8.0 this is:
C:\ORADIM80 -DELETE -SID
For Oracle 8i or higher this is:
C:\ORADIM -DELETE -SID
Also create the new Oracle Database 10gR2 service at a command prompt using the
ORADIM command of the new Oracle Database release:
C:\> ORADIM -NEW -SID SID -INTPWD PASSWORD -MAXUSERS USERS
-STARTMODE AUTO -PFILE ORACLE_HOME\DATABASE\INITSID.ORA
Step 25:
~~~~~~~~
Copy configuration files from the ORACLE_HOME of the database being upgraded
to the new Oracle Database 10g ORACLE_HOME:
If your parameter file resides within the old environment's ORACLE_HOME,
then copy it to the new ORACLE_HOME. By default, Oracle looks for the parameter
file in ORACLE_HOME/dbs on UNIX platforms and in ORACLE_HOME\database on
Windows operating systems. The parameter file can reside anywhere you wish,
but it should not reside in the old environment's ORACLE_HOME after you
upgrade to Oracle Database 10g.
If your parameter file is a text-based initialization parameter file with
either an IFILE (include file) or a SPFILE (server parameter file) entry,
and the file specified in the IFILE or SPFILE entry resides within the old
environment's ORACLE_HOME, then copy the file specified by the IFILE or
SPFILE entry to the new ORACLE_HOME. The file specified in the IFILE or SPFILE
entry contains additional initialization parameters.
If you have a password file that resides within the old environments
ORACLE_HOME, then move or copy the password file to the new Oracle Database
10g ORACLE_HOME.
The name and location of the password file are operating system-specific.
On UNIX platforms, the default password file is ORACLE_HOME/dbs/orapwsid.
On Windows operating systems, the default password file is
ORACLE_HOME\database\pwdsid.ora. In both cases, sid is your Oracle instance ID.
If you are upgrading a cluster database and your initdb_name.ora file resides
within the old environment's ORACLE_HOME, then move or copy the initdb_name.ora
file to the new ORACLE_HOME.
Note:
If you are upgrading a cluster database, then perform this step on all nodes
in which this cluster database has instances configured.
Step 26:
~~~~~~~~
Update the oratab entry, to set the new ORACLE_HOME and disable automatic
startup:
::N
Step 27:
~~~~~~~~
Update the environment variables like ORACLE_HOME and PATH
$. oraenv
Step 28:
~~~~~~~~
Make sure the following environment variables point to the new
Release directories:
- ORACLE_HOME
- PATH
- ORA_NLS10
- ORACLE_BASE
- LD_LIBRARY_PATH
- LD_LIBRARY_PATH_64 (Solaris only)
- LIBPATH (AIX only)
- SHLIB_PATH (HPUX only)
- ORACLE_PATH
$ env | grep ORACLE_HOME
$ env | grep PATH
$ env | grep ORA_NLS10
$ env | grep ORACLE_BASE
$ env | grep LD_LIBRARY_PATH
$ env | grep ORACLE_PATH
AIX:
$ env | grep LIBPATH
HP-UX:
$ env | grep SHLIB_PATH
Note that the ORA_NLS10 environment variable replaces the ORA_NLS33 environment
variable, so you may need to unset ORA_NLS33 and set ORA_NLS10.
Step 29:
~~~~~~~~
Startup upgrade the database:
$ cd $ORACLE_HOME/rdbms/admin
$ sqlplus / as sysdba
Use Startup with the UPGRADE option:
SQL> startup upgrade
Step 30:
~~~~~~~~
Create a SYSAUX tablespace. In Oracle Database 10g, the SYSAUX tablespace is
used to consolidate data from a number of tablespaces that were separate in
previous releases.
The SYSAUX tablespace must be created with the following mandatory attributes:
- ONLINE
- PERMANENT
- READ WRITE
- EXTENT MANAGEMENT LOCAL
- SEGMENT SPACE MANAGEMENT AUTO
The Upgrade Information Tool(utlu102i.sql in step 4) provides an estimate of
the minimum required size for the SYSAUX tablespace in the SYSAUX Tablespace
section.
The following SQL statement would create a 500 MB SYSAUX tablespace
for the database:
SQL> CREATE TABLESPACE sysaux DATAFILE 'sysaux01.dbf'
SIZE 500M REUSE
EXTENT MANAGEMENT LOCAL
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;
Step 31:
~~~~~~~~
If table XDB.MIGR9202STATUS exists in the database, drop it before upgrading
the database (to avoid the issue described in )
Step 32:
~~~~~~~~
Spool the output so you can take a look at possible errors after the upgrade:
SQL> spool upgrade.log
SQL> @catupgrd.sql
The catupgrd.sql script determines which upgrade scripts need to be run and then runs
each necessary script. You must run the script in the new release 10.2 environment.
The upgrade script creates and alters certain data dictionary tables. It also upgrades
and configures the following database components in the new release 10.2 database (if
the components were installed in the database before the upgrade)
Oracle Database Catalog Views
Oracle Database Packages and Types
JServer JAVA Virtual Machine
Oracle Database Java Packages
Oracle XDK
Oracle Real Application Clusters
Oracle Workspace Manager
Oracle interMedia
Oracle XML Database
OLAP Analytic Workspace
Oracle OLAP API
OLAP Catalog
Oracle Text
Spatial
Oracle Data Mining
Oracle Label Security
Messaging Gateway
Expression Filter
Oracle Enterprise Manager Repository
Turn off the spooling of script results to the log file:
SQL> SPOOL OFF
Then, check the spool file and verify that the packages and procedures
compiled successfully. You named the spool file earlier in this step; the
suggested name was upgrade.log. Correct any problems you find in this file
and rerun the appropriate upgrade script if necessary. You can rerun any
of the scripts described in this note as many times as necessary.
Step 33:
~~~~~~~~
Run utlu102s.sql, specifying the TEXT option:
SQL> @utlu102s.sql TEXT
This is the Post-upgrade Status Tool displays the status of the database
components in the upgraded database. The Upgrade Status Tool displays output
similar to the following:
Oracle Database 10.2 Upgrade Status Utility 04-20-2005 05:18:40
Component Status Version HH:MM:SS
Oracle Database Server VALID 10.2.0.1.0 00:11:37

Oracle XDK VALID 10.2.0.1.0 00:02:15
Oracle Database Java Packages VALID 10.2.0.1.0 00:00:48
Oracle Text VALID 10.2.0.1.0 00:00:28
Oracle XML Database VALID 10.2.0.1.0 00:01:27
Oracle Workspace Manager VALID 10.2.0.1.0 00:00:35
Oracle Data Mining VALID 10.2.0.1.0 00:15:56

Spatial VALID 10.2.0.1.0 00:05:37
Oracle Ultra Search VALID 10.2.0.1.0 00:00:46
Oracle Label Security VALID 10.2.0.1.0 00:00:14
Oracle Expression Filter VALID 10.2.0.1.0 00:00:16
Oracle Enterprise Manager VALID 10.2.0.1.0 00:00:58
Note - in RAC environments, this script may suggest that the status of the
RAC component is INVALID when in actual fact it is VALID (as shown in the
output from DBA_REGISTRY)
Step 34:
~~~~~~~~
Restart the database:
SQL> shutdown immediate (DO NOT USE SHUTDOWN ABORT!!!!!!!!!)
SQL> startup restrict
Executing this clean shutdown flushes all caches, clears buffers and performs
other database housekeeping tasks. Which is needed if you want to upgrade
specific components.
Step 35:
~~~~~~~~
Run olstrig.sql to re-create DML triggers on tables with Oracle Label Security policies.
This step is only necessary if Oracle Label Security is in your database.
(Check from Step 33).
SQL> @olstrig.sql
Step 36:
~~~~~~~~
Run utlrp.sql to recompile any remaining stored PL/SQL and Java code.
SQL> @utlrp.sql
Verify that all expected packages and classes are valid:
If there are still objects which are not valid after running the script run
the following:
spool invalid_post.lst
Select substr(owner,1,12) owner,
substr(object_name,1,30) object,
substr(object_type,1,30) type, status
from
dba_objects where status <>'VALID';
spool off
Now compare the invalid objects in the file 'invalid_post.lst' with the invalid
objects in the file 'invalid_pre.lst' you create in step 9.
NOTE: If you have upgraded from version 9.2 to version 10.2 and find that the
following views are invalid, the views can be safely ignored (or dropped):
SYS.V_$KQRPD
SYS.V_$KQRSD
SYS.GV_$KQRPD
SYS.GV_$KQRSD
After Upgrading a Database
--------------------------
Step 37:
~~~~~~~~
Shutdown the database and startup the database.
$ sqlplus '/as sysdba'
SQL> shutdown
SQL> startup restrict
Step 38:
~~~~~~~~
Complete the Step 38 only if you upgraded your database from release 8.1.7
Otherwise skip to Step 40.
A) IF you are NOT using N-type columns for *user* data:
select distinct OWNER, TABLE_NAME from DBA_TAB_COLUMNS where
DATA_TYPE in ('NCHAR','NVARCHAR2', 'NCLOB') and OWNER not in
('SYS','SYSTEM');
did not return rows in Step 7 of this note.
then:
$ sqlplus '/as sysdba'
SQL> shutdown immediate
and go to step 40.
B) IF your version 8 NLS_NCHAR_CHARACTERSET was UTF8:
you can look up your previous NLS_NCHAR_CHARACTERSET using this select:
select * from nls_database_parameters where parameter ='NLS_SAVED_NCHAR_CS';
then:
$ sqlplus '/as sysdba'
SQL> shutdown immediate
and go to step 40.
C) IF you are using N-type columns for *user* data *AND*
your previous NLS_NCHAR_CHARACTERSET was in the following list:
JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED
then the N-type columns *data* need to be converted to AL16UTF16:
To upgrade user tables with N-type columns to AL16UTF16 run the
script utlnchar.sql:
$ sqlplus '/as sysdba'
SQL> @utlnchar.sql
SQL> shutdown immediate;
go to step 40.
D) IF you are using N-type columns for *user* data *AND *
your previous NLS_NCHAR_CHARACTERSET was *NOT* in the following list:
JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED
then import the data exported in point 8 of this note.
The recommended NLS_LANG during import is simply the NLS_CHARACTERSET,
not the NLS_NCHAR_CHARACTERSET
After the import:
$ sqlplus '/as sysdba'
SQL> shutdown immediate;
go to step 40.
Step 39:
~~~~~~~~
If your database has TIMESTAMP WITH TIMEZONE data, you must update
the data so that it is converted and stored based on the new time
zone rules that come with the upgrade. (Step 6).
If you used the export utility to export a copy of the affected tables,
you should now use the import utility to import your data from these tables
back into your database. The import utility will update the timestamp
data as it imports.
If you used the manual script method, you will need to update the affected
timestamp data based on your backed up table. For example, if you previously
backed up your table, you need to run an update statement similar to the
one below to update your timestamp data.
UPDATE tztab t SET t.y =
(SELECT to_timestamp_tz(t1.y,'YYYY-MM-DD HH24.MI.SSXFF TZR')
FROM tztab_back t1
WHERE t.x=t1.x);
Step 40:
~~~~~~~~
Now edit the init.ora:
- If you change the value for NLS_LENGTH_SEMANTICS prior to the upgrade put the
value back to CHAR.
- If you changed the CLUSTER_DATABASE parameter prior the upgrade set it back to TRUE
Step 41:
~~~~~~~~
Startup the database:
SQL> startup
Create a server parameter file with a initialization parameter file
SQL> create spfile from pfile;
This will create a spfile as a copy of the init.ora file located in the
$ORACLE_HOME/dbs directory.
Step 42:
~~~~~~~~
Modify the listener.ora file:
For the upgraded intstance(s) modify the ORACLE_HOME parameter
to point to the new ORACLE_HOME.
Step 43:
~~~~~~~~
Start the listener
$ lsnrctl
LSNRCTL> start
Step 44:
~~~~~~~~
Enable cron and batch jobs
Step 45:
~~~~~~~~
Change oratab entry to use automatic startup
SID:ORACLE_HOME:Y
Step 46:
~~~~~~~~
Upgrade the Oracle Cluster Registry (OCR) Configuration
If you are using Oracle Cluster Services, then you must upgrade the
Oracle Cluster Registry (OCR)keys for the database.
* Use srvconfig from the 10g ORACLE_HOME. For example:
% srvconfig -upgrade -dbname db_name -orahome pre-10g_Oracle_home
USEFUL HINTS
-------------
** Upgrading With Read-Only and Offline Tablespaces
The Oracle database can read file headers created prior to Oracle 10g, so you do not
need to do anything to them during the upgrade. The only exception to this is if
you want to transport tablespaces created prior to Oracle 10g, to another platform.
In this case, the file headers must be made read-write at some point before the transport.
However, there are no special actions required on them during the upgrade.
The file headers of offline datafiles are updated later when they are brought online,
and the file headers of read-only tablespaces are updated if and when they are made
read-write sometime after the upgrade. In any other circumstance, read-only tablespaces
never have to be made read-write.
It is a good idea to OFFLINE NORMAL all tablespaces
except for SYSTEM and those containing rollback/UNDO tablespace prior to migration.
This way if migration fails only the SYSTEM and rollback datafiles need to be
restored rather than the entire database.
Note: You must OFFLINE the TABLESPACE as migrate does not allow OFFLINE files
in an ONLINE tablespace.
** Converting Databases to 64-bit Oracle Database Software
If you are installing 64-bit Oracle Database 10g software but were previously
using a 32-bit Oracle Database installation, then the databases will automatically
be converted to 64-bit during the upgrade to Oracle Database 10g except when
upgrading from Release 1 (10.1) to Release 2 (10.2).
The process is not automatic for the release 1 to release 2 upgrade, but is automatic
for all other upgrades. This is because the utlip.sql script is not run during the
release 1 to release 2 upgrade to invalid all PL/SQL objects. You must run the utlip.sql
script as the last step in the release 10.1 environment, before upgrading to release 10.2.
** If error occurs while executing the catupgrd.sql
If an error occurs during the running of the catupgrd.sql script, once the problem is fixed
you can simply rerun the catupgrd.sql script to finish the upgrade process and complete the
the upgrade process.

KNOWN ISSUES
------------
1)
While doing a upgrade from 9iR2 to 10.2.0.X.X, on running the utlu102i.sql
script as directed in step 2
Its output informs to add streams_pool_size=50331648 to the init.ora file.
While adding the parameter Oracle gives streams_pool_size as invalid parameter.
STREAMS_POOL_SIZE, was introduced in release 10gR1
This message may be ignored for database version 9iR2 or less
2)
One of the customer has reported on keeping the shared_pool_size at 150 MB,
catmeta.sql fails with insuffient shared memory during the processing
of view KU$_PHFTABLE_VI.
Please set the shared_pool_size at 200M.
3)
While upgrade following error was encountered.
create or replace
*
ERROR at line 1:
ORA-06553: PLS-213: package STANDARD not accessible.
ORA-00955: name is already used by an existing object
Please make sure to set the following init parameters as below in the spfile/init file or
comment them out to their default values, at the time of upgrading the database.
PLSQL_V2_COMPATIBILITY = FALSE
PLSQL_CODE_TYPE = INTERPRETED # Only applicable to 10gR1
PLSQL_NATIVE_LIBRARY_DIR = ""
PLSQL_NATIVE_LIBRARY_SUBDIR_COUNT = 0
Note 170282.1
Title: PLSQL_V2_COMPATIBLITY=TRUE causes STANDARD and
DBMS_STANDARD to Error at Compile
4)
sqlplus crashes with OCI-21500 error and a core dump
when "set serveroutput on"
is run in the same session where startup command is executed.
This issue is reported in BUG:4860003
Always disconnect from the session which issues the STARTUP and
connect as a fresh session before doing any further SQL.
eg: On upgrade to 10.2 startup the instance with the upgrade option,
exit sqlplus , reconnect a fresh SQLPLUS session as SYSDBA
and then run the upgrade scripts.
