Oracle RAC manually patch rollback

1. Stop the CRS managed resources running from DB homes.
   If this is a GI Home environment, as the database home owner execute:
   $ <ORACLE_HOME>/bin/srvctl stop home -o <ORACLE_HOME> -s <status file location> -n <node name>
   If this is an Oracle Restart Home environment, as the database home owner execute:
   $ <ORACLE_HOME>/bin/srvctl stop home -o <ORACLE_HOME> -s <status file location>

2. Run the pre root script.
   If this is a GI Home, as the root user execute:
   <GI_HOME>/crs/install/rootcrs.pl -unlock
   If this is an Oracle Restart Home, as the root user execute:
   <GI_HOME>/crs/install/roothas.pl -unlock

3. Roll back the CRS patch. As the GI home owner execute:
   $ <GI_HOME>/OPatch/opatch rollback -local -id <OCW Components_number> -oh <GI_HOME>
   $ <GI_HOME>/OPatch/opatch rollback -local -id <ACFS Components_number> -oh <GI_HOME>
   $ <GI_HOME>/OPatch/opatch rollback -local -id <DB_PSU_number> -oh <GI_HOME>

4. Run the pre script for DB component of the patch. As the database home owner execute:
   $ <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<OCW Components_number>/custom/server/<OCW Components_number>/custom/scripts/prepatch.sh -dbhome <ORACLE_HOME>

5. Roll back the DB patch from the database home. As the database home owner execute:
   $ <ORACLE_HOME>/OPatch/opatch rollback -local -id <OCW Components_number> -oh <ORACLE_HOME>
   $ <ORACLE_HOME>/OPatch/opatch rollback -local -id <DB_PSU_number> -oh <ORACLE_HOME>

6. Run the post script for DB component of the patch. As the database home owner execute:
   $ <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<OCW Components_number>/custom/server/<OCW Components_number>/custom/scripts/postpatch.sh -dbhome <ORACLE_HOME>

7. Run the post script. As the root user execute:
   <GI_HOME>/rdbms/install/rootadd_rdbms.sh
   If this is a GI Home, as the root user execute:
   <GI_HOME>/crs/install/rootcrs.pl -patch
   If this is an Oracle Restart Home, as the root user execute:
   <GI_HOME>/crs/install/roothas.pl -patch

8. If the message, "A system reboot is recommended before using ACFS??? is shown, then a reboot must be issued before continuing. Failure to do so will result in running with an unpatched ACFS\ADVM\OKS driver.

9. Start the CRS managed resources that were earlier running from DB homes.
   If this is a GI Home environment, as the database home owner execute:
   $ <ORACLE_HOME>/bin/srvctl start home -o <ORACLE_HOME> -s <status file location> -n <node name>
   If this is an Oracle Restart Home environment, as the database home owner execute:
   $ <ORACLE_HOME>/bin/srvctl start home -o <ORACLE_HOME> -s <status file location>

1. Close a database node:

$ srvctl  stop home -o $ORACLE_HOME -s /tmp/stophome1.log -n rac2

2. Lock node GI:

  /u01/app/11.2.0/grid/crs/install/rootcrs.pl -unlock

3. rollback patches under the GI HOME, performed with the GI users:

$ $ORACLE_HOME/OPatch/opatch rollback -local -id 27441052 -oh $ORACLE_HOME
$ $ORACLE_HOME/OPatch/opatch rollback -local -id 22502505  -oh $ORACLE_HOME
$ $ORACLE_HOME/OPatch/opatch rollback -local -id 27338049 -oh $ORACLE_HOME 

4. oracle user detection using a script:

$/u01/app/stage/27475913/27441052/custom/server/27441052/custom/scripts/prepatch.sh -dbhome $ORACLE_HOME 

The database rollback patches at home, execution oracle user:

 $ORACLE_HOME/OPatch/opatch rollback -local -id 27441052 -oh $ORACLE_HOME
 $ORACLE_HOME/OPatch/opatch rollback -local -id 27338049 -oh $ORACLE_HOME

6. Execute the script with the oracle user:

$/u01/app/stage/27475913/27441052/custom/server/27441052/custom/scripts/postpatch.sh -dbhome $ORACLE_HOME 

7. Execute the script with root user:

  /u01/app/11.2.0/grid/rdbms/install/rootadd_rdbms.sh 
 /u01/app/11.2.0/grid/crs/install/rootcrs.pl -patch

8. Open node instance:

$ srvctl start home -o $ORACLE_HOME -s /tmp/stophome1.log -n rac2

9. Update Data Dictionary (single node operation):

---更新数据字典
SQL> @?/rdbms/admin/catbundle.sql psu apply
---编译java类
SQL> @?/rdbms/admin/utlrp.sql
