Database Upgrade Assistant (DBUA)

 

Preamble

I have always used the manual upgrade method to keep up to date my Oracle databases. So using, for 11gR2 target release of this post, Oracle reference note: Complete Checklist for Manual Upgrades to 11gR2 [ID 837570.1]. This time I wanted to use the suggested Oracle method i.e. using Database Upgrade Assistant (DBUA). So using reference note Complete checklist to upgrade the database to 11g R2 using DBUA [ID 870814.1].

DBUA pre-upgrade

When using DBUA you need to have both Oracle binaries in parallel, which is an issue for me as my standards for ORACLE_HOME does not contains the release number (i.e. /ora_<sid>/software). So copy old software to software_102.

Rename all the symbolic links with:

find . -type l -exec ls -l {} ; | grep "/ora_10g/software" | awk '{printf "%s %sn",$9,$11}' | while read l1 l2
do
  rm -f $l1
  L2=`echo $l2 | sed 's!/ora_10g/software!/ora_10g/software_102!'`
  ln -s $L2 $l1
done

Change the environment variables of your Unix account to point to new Oracle home. Relink the software and change the ORACLE_HOME in $TNS_ADMIN/listener.ora file:

[ora10g@server1 dbs]$ relink all
[ora10g@server1 dbs]$ vi $TNS_ADMIN/listener.ora

Then it’s time to install 11gR2 binaries in correct ORACLE_HOME( just to make sure your oraInventory will be usable for further upgrade) and associated latest PSU available on Oracle web site.

Then issue utlu112i.sql script from newly created Oracle home:

SQL> @/ora_10g/software/rdbms/admin/utlu112i.SQL

PL/SQL PROCEDURE successfully completed.

We need to solve few issues before going further:

  • Increased Undotbs to 400MB.
  • Issued, as SYS:
    SQL> PURGE DBA_RECYCLEBIN;
     
    DBA Recyclebin purged.
  • Computed dictionary statistics:
    SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;
     
    PL/SQL PROCEDURE successfully completed.
  • Finally issued utlrp.sql script to recompile all invalid objects

Re-issued utlu112i.sql script but still complaining for time zone, SYS stale statistics, dependencies on network packages and recycle bin:

WARNING: --> Database is using a timezone file older than version 11.
.... After the RELEASE migration, it IS recommended that DBMS_DST PACKAGE

As suggested followed Oracle note Script to Check Schemas with Stale Statistics [ID 560336.1] and issue what has been generated by script:

SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS('SYS',OPTIONS=>'GATHER', ESTIMATE_PERCENT  => DBMS_STATS.AUTO_SAMPLE_SIZE, METHOD_OPT => 'FOR ALL COLUMNS SIZE AUTO', CASCADE => TRUE);
 
PL/SQL PROCEDURE successfully completed.

But still complains about SYS stale statistics…

For time zone issue followed Actions For DST Updates When Upgrading To 11.2.0.1 Base Release [ID 815679.1] and for release 10.2.0.4 warning can be discarded. Actions can be taken after 11gR2 upgrade with:

  • update to DSTv11 by following Note 977512.1 Updating the RDBMS DST version in 11gR2 (11.2.0.1 and up) using DBMS_DST.
  • update to a higher DST than 11 version if this is needed. The latest DST patch is found in Note 412160.1 Updated DST transitions and new Time Zones in Oracle Time Zone File patches.

For the warning on Database contains schemas with objects dependent on network packages it is explained in “WARNING: –> Database contains schemas with objects dependent on network packages” When Running utlu111i.sql [ID 797750.1]. So can be safely ignored.

DBUA upgrade

/etc/oratab must contains an entry with the database you plan to upgrade, unless you don’t see anything in available database to upgrade screen.

Issue 11gR2 DBUA tool. Nothing particular to mention for the few additional questions asked by DBUA, except maybe the additional 31MB for SYSTEM tablespace asked to perform the upgrade.

DBUA throw PLS-00201: identifier SYS.DBMS_JAVA must be declared error message and this is explained in Oracle support note 11GR2 DBUA ORA-06550 PLS-00201 IDENTIFIER SYS.DBMS_JAVA MUST BE DECLARED [ID 1066828.1]. So I just ignored it…

DBUA post-upgrade

I remastered the init.ora and removed the spfile that has been created as not using it. Also copied files from old $TNS_ADMIN directory.

DST stands for Daylight Saving Time. DST files are under $ORACLE_HOME/oracore/zoneinfo directory and with their name you are able to see which DST releases are currently support:

[ora10g@server1 zoneinfo]$ cd $ORACLE_HOME/oracore/zoneinfo
[ora10g@server1 zoneinfo]$ ls
big           timezlrg_10.dat  timezlrg_3.dat  timezlrg_7.dat   timezone_11.dat  timezone_4.dat  timezone_8.dat
little        timezlrg_11.dat  timezlrg_4.dat  timezlrg_8.dat   timezone_1.dat   timezone_5.dat  timezone_9.dat
readme.txt    timezlrg_1.dat   timezlrg_5.dat  timezlrg_9.dat   timezone_2.dat   timezone_6.dat
timezdif.csv  timezlrg_2.dat   timezlrg_6.dat  timezone_10.dat  timezone_3.dat   timezone_7.dat

With 11gR2 base release (11.2.0.1.0) DST up to 11 are supported, with 11.2.0.2.0 DST release up to 14 are supported. You can anyway install latest DST file on a base release directory. I choose the simplest method and will try to upgrade the database to DST 11.

To see which DST file you database is currently using you can issue:

SQL> SELECT version FROM v$timezone_file;
 
   VERSION
----------
         4

So followed Oracle note 977512.1:

Preparation was quite positive as no error. Choose DST 11 as latest available and launched the DST upgrade.
