Dataguard : Applying CPU(Cirital Patch Update) to Dataguard Environment

I have One Primary database and 2 Physical Standby Databases under RHEL 5. Here is a process to patch them with JULY CPU update “Critical Patch Update Release 10.2.0.4 for UNIX Released July 13, 2010”

At Primary Site
SQL> show parameter dg_broker_start

NAME                                 TYPE        VALUE
———————————— ———– ——————————
dg_broker_start                      boolean     TRUE

SQL> alter system switch logfile;
System altered.

Make sure the Logs are shipped and both Standby Database and applied. Following SQLs could be used to locate the log sequences on all databases.

Locate Primary Log Sequence :   Select Archived_Seq# From V$Archive_Dest_Status Where Dest_Id=1;

Locate Standby Log Sequence :  Select Archived_Seq#, Applied_Seq# From V$Archive_Dest_Status Where Dest_Id=2;

Locate DR Log Sequence :   Select Archived_Seq#, Applied_Seq# From V$Archive_Dest_Status Where Dest_Id=3;

Find out existing Patch details using following queries :

SELECT comments, action_time, id “PATCH_NUMBER”, version FROM sys.registry$history WHERE action = ‘CPU’;

COMMENTS	ACTION_TIME	PATCH_NUMBER	VERSION
view recompilation	42:39.2	6452863
view recompilation	59:20.3	6452863
view recompilation	23:58.7	6452863
view recompilation	56:19.9	6452863

SELECT comments, action_time, id PATCH_NUMBER, version FROM sys.registry$history

COMMENTS	ACTION_TIME	PATCH_NUMBER	VERSION
Upgraded from 10.2.0.1.0	40:28.8		10.2.0.4.0
CPUApr2009	46:06.0	4	10.2.0.4
view recompilation	42:39.2	6452863
CPUOct2009	56:35.7	6	10.2.0.4
view recompilation	59:20.3	6452863
CPUJan2010	01:47.4	6	10.2.0.4
view recompilation	23:58.7	6452863

Backup Primary database  & then shutdown Primary Database

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

For each database instance running on the Oracle home being patched, connect to the database using SQL*Plus.

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catbundle.sql cpu apply
SQL> — Execute the next statement only if this is the first 10.2.0.4 CPU applied in the Oracle home.
SQL> @utlrp.sql
SQL> QUIT

Run the view recompilation script. Note that this script is run with the database in upgrade mode, which restricts connections as SYSDBA.

cd $ORACLE_HOME/cpu/view_recompile
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP UPGRADE
SQL> @view_recompile_jan2008cpu.sql
SQL> SHUTDOWN;

Finally run following commands to make sure logs are appied at standbydatabases:

Locate Primary Log Sequence :   Select Archived_Seq# From V$Archive_Dest_Status Where Dest_Id=1;

Locate Standby Log Sequence :  Select Archived_Seq#, Applied_Seq# From V$Archive_Dest_Status Where Dest_Id=2;

Locate DR Log Sequence :   Select Archived_Seq#, Applied_Seq# From V$Archive_Dest_Status Where Dest_Id=3;
