Manually Upgrading RAC database from 10.2.0.1 to 10.2.0.4

After upgrading the CRS from 10.2.0.1 to 10.2.0.4 (link -> https://shivanandarao-oracle.com/2013/03/04/upgrade-crs-from-10-2-0-1-to-10-2-0-4/), now lets move on upgrading the database from 10.2.0.1 to 10.2.0.4

Step 1:
Lets stop the database running on both the nodes 10gnode1 and 10gnode2. Once the database is stopped, we shall stop the ASM instances and the nodeapps running on all the nodes.

[oracle@10gnode1 ~]$ srvctl stop database -d srprim
[oracle@10gnode1 ~]$ srvctl stop asm -n 10gnode1
[oracle@10gnode2 ~]$ srvctl stop asm -n 10gnode2
[oracle@10gnode1 ~]$ srvctl stop nodeapps -n 10gnode1
[oracle@10gnode2 ~]$ srvctl stop nodeapps -n 10gnode2

Step 2:
From the unzipped patch, run the runInstaller file on 10gnode1.
Select the 10g Database home that needs to be upgraded and verify the home path.

Once the patch has been applied, the installation would recommend you to run root.sh script from the 10g Database home as ROOT user. Run the script on both the nodes.

[root@10gnode1 ~]# /u01/app/oracle/product/10.2.0/db_1/root.sh
[root@10gnode2 ~]# /u01/app/oracle/product/10.2.0/db_1/root.sh

Step 3:
Now, lets start the Nodeapps and the ASM instances on both the nodes.

[oracle@10gnode1 ~]$ srvctl start nodeapps -n 10gnode1
[oracle@10gnode2 ~]$ srvctl start nodeapps -n 10gnode2
[oracle@10gnode1 ~]$ srvctl start asm -n 10gnode1
[oracle@10gnode2 ~]$ srvctl start asm -n 10gnode2

Step 4:
Database Upgrade.

On 10gnode1, start the instance “srprim1”. Since we are upgrading the database, we are starting up only one instance.

[oracle@10gnode1 dbs]$ export ORACLE_SID=srprim1
[oracle@10gnode1 dbs]$ export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
[oracle@10gnode1 dbs]$ sqlplus / as sysdba

Variable Size 247467044 bytes

Step 5:

Create pfile from SPFILE in order to remove the below mentioned Cluster Parameters.

SQL> create pfile='/u01/initsrprim1.ora' from spfile;

File created.

SQL> shut immediate
ORA-01507: database not mounted
ORACLE instance shut down.

Step 6:
Now, remove or comment the below mentioned cluster parameters in the newly created pfile.


vi /u01/initsrprim1.ora
#REMOVE THESE PARAMETERS#
#*.cluster_database_instances=2
#*.cluster_database=true
#srprim2.instance_number=2
#srprim1.instance_number=1

Step 7:
Startup the instance “srprim1” in upgrade mode using the modified PFILE.

[oracle@10gnode1 dbs]$ sqlplus / as sysdba

SQL> startup upgrade pfile='/u01/initsrprim1.ora';

Database mounted.
Database opened.

Step 8:
Once the database is started up in the UPGRADE mode, run the CATUPGRD.SQL script to carryout the upgrade process.


SQL> spool '/u01/10204upgrd.txt';
SQL> @/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catupgrd.sql

Step 9:
Once the script is executed successfully, shutdown the database and open it normally using the above pfile. Run the utlrp.sql script from the 10.2.0 Oracle DB home/rdbms/admin path to validate the invalid objects.


[oracle@10gnode1 dbs]$ sqlplus / as sysdba

STEP 10:
Now, lets start the instance “srprim1” using the global SPFILE rather than the temporary PFILE (“/u01/initsrprim1.ora”)


SQL> startup
ORACLE instance started.

Total System Global Area 926941184 bytes

SQL> select * from v$version;

CORE 10.2.0.4.0 Production
TNS for Linux: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production

Step 11:
Now that the SRPRIM database is upgraded to 10.2.0.4, lets check the status of the instances using SRVCTL


[oracle@10gnode1 dbs]$ srvctl status database -d srprim
Instance srprim1 is running on node 10gnode1
Instance srprim2 is not running on node 10gnode2
[oracle@10gnode1 dbs]$

In STEP 6 through STEP 9, you can notice that the upgrade was carried out using a temporary PFILE located at “/u01/initsrprim1.ora” and that no changes were made to the original PFILE or SPFILE (globally located).

Hence after the upgrade was done successfully, I had no necessity of uncommenting the changes done to the CLUSTER parameters in the temporary PFILE. The instance “srprim1” has been started using the Global SPFILE which can be noticed in STEP 10.

You can notice above that the instance “srprim2” is not started.
Lets start it using the “SRVCTL start instance” command.

[oracle@10gnode1 dbs]$ srvctl start instance -d srprim -i srprim2

Lets crossverify once again the status of all the instances.

[oracle@10gnode1 dbs]$ srvctl status database -d srprim
Instance srprim1 is running on node 10gnode1
Instance srprim2 is running on node 10gnode2

Here you go !!
