11.2.0.2

Upgrading Grid Infrastructure 11.2.0.1 to 11.2.0.2 on RHEL4

11.2.0.2 Patchset was released few days back. I decided to upgrade a test RAC database to 11.2.0.2 yesterday and was able to do it successfully. I will be documenting the steps here for easy reference

Environment Details

2 node RAC on Red Hat Enterprise Linux AS release 4 (Nahant Update 8), 64 bit

To upgrade existing 11.2.0.1 Oracle Grid Infrastructure installations to Oracle Grid Infrastructure 11.2.0.2, you must first do at least one of the following:

– Patch the release 11.2.0.1 Oracle Grid Infrastructure home with the fix for bug 9413827.
– Install Oracle Grid Infrastructure Patch Set 1 (GIPS1) or Oracle Grid Infrastructure Patch Set 2 (GIPS2).

I will be using Oracle Grid Infrastructure Patch set 2.

Software and Patches

1) Download Patch 9655006 – 11.2.0.1.2 for Grid Infrastructure (GI) Patch Set Update from MOS

2) Latest Opatch for 11.2 – 6880880 Universal Installer: Patch OPatch 11.2

You can refer to How To Download And Install OPatch [ID 274526.1]

3)11.2.0.2 Patchset files. You can find method to download them directly to server here

Lets get started.

Install Latest Opatch

Unzip the zip file and copy OPatch folder to $ORACLE_HOME by renaming the earlier OPatch directory. You can refer to How To Download And Install OPatch [ID 274526.1]

Apply Grid Infrastructure (GI) Patch Set Update –  9655006

It applies patch 9654983 and 9655006 to both Database and Grid home. We proceed by checking for any patch conflicts

We need to use opatch auto to patch both Grid Infrastructure and RAC database home.It can be used to patch separately but I am going with patching both. This is great improvement over 10g CRS patch bundles as it had lot of steps to be run as root or oracle software owner. ( I had myself messed up once by running a command as root instead of oracle 🙁 ) Opatch starts with patching the database home and then patches the grid infrastructure home. You can stop the database instance running out of oracle home.(opatch asks for shutting down database, so in case you do not stop,don’t worry it will warn)

Note: In case you are on RHEL5/OEL5 and using ACFS for database volumes, it is recommended to use opatch auto <loc> -oh <grid home> to first patch the Grid home instead of patching them together

Unzip patch 965506 to directory say /oracle/software/gips2.It will create two directories for patch 9654983 and 9655006. Connect as root user and set the oracle home and Opatch directory . Stop the database instance running on the node

srvctl stop instance -d db11g -i db11g1

Next run opatch auto command as root

#opatch auto /oracle/software/gips2

This is a known issue and discussed in 11.2.0.X Grid Infrastructure PSU Known Issues [ID 1082394.1]

To solve this issue, connect as root user and execute following command from your Grid Infrastructure home

cd $GRID_HOME

# ./crs/install/rootcrs.pl -patch
2010-10-02 06:59:54: Parsing the host name
2010-10-02 06:59:54: Checking for super user privileges

ADVM/ACFS is not supported on Redhat 4

CRS-4123: Oracle High Availability Services has been started.

Start oracle database instance on the node which has been patched

srvctl start instance -d db11g -i db11g1

Repeat the above steps for node 2.It took me 40 minutes for each node to complete opatch auto activity.Once it is done,execute following from one node for all databases to complete patch installation

cd $ORACLE_HOME/rdbms/admin

sqlplus /nolog

SQL> CONNECT / AS SYSDBA

SQL> @catbundle.sql psu apply

SQL> QUIT

This completes patching of Grid Infrastructure Patch or PSU2.

Upgrading Grid Infrastructure home to 11.2.0.2

Ensure following environment variables are not set :ORA_CRS_HOME; ORACLE_HOME; ORA_NLS10; TNS_ADMIN

# echo $ORA_CRS_HOME; echo $ORACLE_HOME; echo $ORA_NLS10; echo $TNS_ADMIN

Strating with 11.2.0.2, Grid infrastructure (Clusterware and ASM Home) upgrade is out of place upgrade i.e we install in new ORACLE_HOME. Unlike database home we cannot perform an in-place upgrade of Oracle Clusterware and Oracle ASM to existing homes.

Unset following variables too

$ unset ORACLE_BASE

$ unset ORACLE_HOME

$ unset ORACLE_SID

Relax permissions for GRID_HOME

#chmod -R 755 /oracle/product/grid

#chown -R oracle /oracle/product/grid

#chown oracle /oracle/product

Start the runInstaller from the 11.2.0.2 grid software directory.

On first screen, it will ask for MOS details. I have chosen skip Software update

Since we are upgrading existing installation, choose “Upgrade Oracle Grid Infrastructure or Oracle Automatic Storage Management”. This will install software and also configure ASM

Next screen displays nodes which OUI will patch

Select the OSDBA,OSASM and OSOPER group. I have chosen dba

Since I have chosen all 3 groups to be same, it gives warning. Select Yes to continue

Specify the grid software installation directory. I have used /oracle/product/oragrid/11.2.0.2 (Better to input release as we will be having out of place upgrades for future patchsets too)

OUI reports some issues with swap size ,shmmax and NTP. You can fix them or choose to ignore. OUI can create a fixup script for you.

Installation starts copying file. After files have been copied to both nodes, it asks for running the rootupgrade.sh script from all nodes

Stop the database instance running from the node at this time and then run script as root. Please note that ASM and clusterware should not be stopped as rootupgrade.sh requires them to be up and takes care of shutting down and starting with new home.In my case, running rootupgrade.sh successfully succeeded on node 1 but it hung on node 2 . I did a cancel and re-ran it. Pasting the contents from node 2 second run

We see that cluvfy is reporting error that it expected oinstall group but found dba group. I had not specified install group during installation, so can ignore it.For NTP you can correct it by setting following in ntpd.conf and restart the ntpd daemon

grep OPTIONS /etc/sysconfig/ntpd
OPTIONS=”-u ntp:ntp -p /var/run/ntpd.pid -x”

At this moment Grid Infrastructure has been successfully upgraded to 11.2.0.2. Next we will upgrade the RAC database home. You can refer to Steps to Upgrade 11.2.0.1 RAC to 11.2.0.2
