How to Patch Oracle RAC Clusterware 12c and Database Using opatch auto


<<Back to Oracle RAC Main Page

Step by Step Instruction to Patch Oracle RAC Cluster Version 12.1.0.2

Step0: download the PSU and read the readme.txt for the patch. The installation instruction and rollback instruction is provided in readme file.
Transfer the PSU on each node of the RAC cluster. 
Here is the extract and simplified version of Oracle  RAC patching procedure for release version 12.1.0.2 using opatchauto

Step1: Ensure the Latest OPatch utility is Available

Check Current OPatch Utility Version
Verify if the required  OPatch utility as mentioned in readme.txt is available.
$export ORACLE_HOME=/u01/product/12.1.0.2/dbhome1
$export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch
$opatch version
OPatch Version: 12.2.0.1.3
OPatch succeeded.

Upgrade OPatch Utility to The Latest Version
Download the latest OPatch utility version as mentioned in readme.txt. Ensure to upgrade the OPatch utility in all OH homes and GI home on all nodes. Latest OPatch utility for your version is available for Download from My Oracle Support patch 6880880.
To Upgrade the OPatch follow below steps for each OH and GI homes
  1. Download and transfer the OPatch utility file to all the server (I copied it in /u01/stage)
  2. $unzip /u01/stage/p28199085_12102190716_Linux-x86-64.zip
  3. #mv $ORACLE_HOME/OPatch $ORACLE_HOME/OPatch_Backup
  4. # cp /u01/stage/OPatch $ORACLE_HOME/
  5. #chown -R oracle:dba $ORACLE_HOME/OPatch
  6. #chmod -R 755 $ORACLE_HOME/OPatch
  7. #opatch version
OPatch Version: 12.2.0.1.17
OPatch succeeded.


Step2: Perform Complete Cluster Stack Health Check: Strongly Recommended


Download latest ORACheck utility install it and run it to perform the cluster health check. You can find the instruction guide, download package etc at MOS Note 1268927.2
If you have latest version of TFA installed and configured ORACheck is part of TFA and already installed in your environment.You can run racheck directly from tfa CLI interface as below
$tfactl
tfactl> orachk
CRS stack is running and CRS_HOME is not set. Do you want to set CRS_HOME to /u01/grid/product/12.1.0.2/gi?[y/n][y]
Follow the screen instruction to and wait for completion of ORACheck execution.
Analyze the output file and fix any possible errors before proceeding to next step

Step3: Prepare the Node for Patching
NOTE: Since the patching is done in rolling mode to avoid any outage for application, ensure the database and services is always available from available node in the cluster

Verify the Database Services Running on Node1
$srvctl status service -d DB1
Service srv1 is running on instance(s) DB11,DB12
$srvctl status service -d DB2
Service srv2 is running on instance(s) DB21,DB22

Stop or relocate the services from the node1 to node2
NOTE: In production environment run this step at least few hours before starting the patching to ensure that all the sessions are properly gone from node1.  In my case, since the services are running on all the nodes I will simply stop them on node1 (the node which I am going to patch first)
$srvctl stop service -d DB1 -s srv1 -n node1
$srvctl stop service -d DB2 -s srv2 -n node1

Verify and Confirm that All the Services are now running on 2nd node and no service is running on node1
$srvctl status service -d DB1
Service srv1 is running on instance(s) DB21
$srvctl status service -d DB2
Service srv2 is running on instance(s) DB22

Verify and Ensure that there is no Active Session and Transactions Running on Node1
$ sqlplus "/as sysdba"
select SID,USERNAME,STATUS from v$session where username not in ('SYS','DBSNMP');
no rows selected

col machine for a30
col username for a30
col program for a30 trun
col sid for 99999
set lines 300select sid,USED_UBLK,username,program,machine,systimestamp
from v$transaction t, v$session s
where SES_ADDR = s.saddr order by 1;
no rows selected

select sid,USED_UBLK,username,program,machine,systimestamp
from gv$transaction t, gv$session s
where SES_ADDR = s.saddr order by 1;
no rows selected

NOTE: if you are using OPatch utility 12.2.0.1.5 or later you do not need OCM(Oracle Configuration Manager) response file any more

Step4: Validate Patch Inventory for all homes
$opatch lsinventory -detail -oh /u01/grid/product/12.1.0.2/gi > /u01/stage/GI_OH_INV
$opatch lsinventory -detail -oh /u01/product/12.1.0.2/dbhome1 > /u01/stage/DB_OH_INV

Step5: Verify and resolve the Patch Conflicts
as root user
# opatchauto apply /u01/stage/29698592 -analyze
to see the sample output of analyze command scroll down

Step6: Run opatch auto to patch node1

NOTE: The Patching Steps are only valid for systems where GI Home and the Database Homes are not shared and ACFS file system is not configured
As root user, execute the following command on node1

#export ORACLE_HOME=/u01/grid/product/12.1.0.2/gi
#export PATH=$PATH:$ORACLE_HOME/OPatch:$ORACLE_HOME/bin
#export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
#opatchauto apply /u01/stage/29698592


to see the sample out put of opatch apply command scroll down

Step7: Repeat step 3 to 6 for node2.

Step8: Verify the patch Installation


$opatch lsinventory -oh /u01/grid/product/12.1.0.2/gi |grep -e 'patch_id1' -e 'patch_id2' -e 'patch_id3'

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE;   System altered.

ORA-46630: keystore cannot be created at the specified location

<<Back to DB Administration Main Page ORA-46630: keystore cannot be created at the specified location CDB011> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "xxxxxxx"; ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "EncTest123" * ERROR at line 1: ORA-46630: keystore cannot be created at the specified location Cause  Creating a keystore at a location where there is already a keystore exists Solution To solve the problem, use a different location to create a keystore (use ENCRYPTION_WALLET_LOCATION in sqlnet.ora file to specify the keystore location), or move this ewallet.p12 file to some other location. Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.
