Upgrade from 11.1.0.7 to 11.2.0.3 (Clusterware, ASM & RAC)

This blog list the steps for two node cluster upgrade from 11.1.0.7 and 11.2.0.3 Two nodes are named rac1 and rac2 running on RHEL 5 with block devices for ocr and vote disks. There's an earlier blog which shows upgrade from 11.1.0.7 to 11.2.0.1 and a recent post with highlights of upgrading from 11.1.0.7 to 11.2.0.4

Relevant section for 11.1 upgrade to 11.2 from GI Install guide.
After you have completed the Oracle Clusterware 11g release 2 (11.2) upgrade, if you did not choose to upgrade Oracle ASM when you upgraded Oracle Clusterware, then you can do it separately using the Oracle Automatic Storage Management Configuration Assistant (asmca) to perform rolling upgrades. You can use asmca to complete the upgrade separately, but you should do it soon after you upgrade Oracle Clusterware, as Oracle ASM management tools such as srvctl will not work until Oracle ASM is upgraded.

ASMCA performs a rolling upgrade only if the earlier version of Oracle ASM is either 11.1.0.6 or 11.1.0.7. Otherwise, ASMCA performs a normal upgrade, in which ASMCA brings down all Oracle ASM instances on all nodes of the cluster, and then brings them all up in the new Grid home.

You can use Oracle Database release 9.2, release 10.x and release 11.1 with Oracle Clusterware 11g release 2 (11.2). However, placing Oracle Database homes on Oracle ACFS that are prior to Oracle Database release 11.2 is not supported, because earlier releases are not designed to use Oracle ACFS.

If you upgrade an existing version of Oracle Clusterware and Oracle ASM to Oracle Grid Infrastructure 11g release 11.2 (which includes Oracle Clusterware and Oracle ASM), and you also plan to upgrade your Oracle RAC database to 11.2, then the required configuration of existing databases is completed automatically when you complete the Oracle RAC upgrade, and this section does not concern you.

However, if you upgrade to Oracle Grid Infrastructure 11g release 11.2, and you have existing Oracle RAC installations you do not plan to upgrade, or if you install older versions of Oracle RAC (9.2, 10.2 or 11.1) on a release 11.2 Oracle Grid Infrastructure cluster, then you must complete additional configuration tasks or apply patches, or both, before the older databases will work correctly with Oracle Grid Infrastructure.

Before you start an Oracle RAC or Oracle Database installation on an Oracle Clusterware 11g release 11.2 installation, if you are upgrading from releases 11.1.0.7, 11.1.0.6, and 10.2.0.4, then Oracle recommends that you check for the latest recommended patches for the release you are upgrading from, and install those patches as needed on your existing database installations before upgrading.

During an upgrade, all cluster member nodes are pinned automatically, and no manual pinning is required for existing databases. This procedure is required only if you install older database versions after installing Oracle Grid Infrastructure release 11.2 software.

To upgrade existing 11.1 Oracle Clusterware installations to Oracle Grid Infrastructure 11.2.0.3 or later, you must patch the release 11.1 Oracle Clusterware home with the patch for bug 7308467.
(Included in PSU 11.1.0.7.6 for CRS) This cluster has 11.1.0.7.7 CRS PSU installed and Jan 2012 PSU installed on RAC.

With Oracle Clusterware 11g release 1 and later releases, the same user that owned the Oracle Clusterware 10g software must perform the Oracle Clusterware 11g upgrade. Before Oracle Database 11g, either all Oracle software installations were owned by the Oracle user, typically oracle, or Oracle Database software was owned by oracle, and Oracle Clusterware software was owned by a separate user, typically crs.

During a major version upgrade to 11g release 2 (11.2), the software in the 11g release 2 (11.2) Oracle Grid Infrastructure home is not fully functional until the upgrade is completed. Running srvctl, crsctl, and other commands from the 11g release 2 (11.2) home is not supported until the final rootupgrade.sh script is run and the upgrade is complete across all nodes. To manage databases in the existing earlier version (release 10.x or 11.1) database homes during the Oracle Grid Infrastructure upgrade, use the srvctl from the existing database homes.


From the Upgrade guide
A subset of nodes cannot be selected when upgrading from an earlier release to 11.2.0.3. Before the new database release 11.2.0.3 software can be installed on the system, the root script for upgrading Oracle Grid Infrastructure invokes ASMCA to upgrade Oracle ASM to release 11.2.0.3.

The cluster verification tool allows a pre-upgrade test. Some noteworthey checks that failed are
Check: Kernel parameter for "shmmni"
  Node Name         Current       Configured    Required      Status        Comment
  ----------------  ------------  ------------  ------------  ------------  ------------
  rac2              4096          unknown       4096          failed        Configured value too low.
  rac1              4096          unknown       4096          failed        Configured value too low.
Result: Kernel parameter check failed for "shmmni"
Even though this is an existing 11gR1 system and this value is set it is considered as unknown. Running the fix script generated by clufy fixed this.

11gR2 has a different port range than 11gR1
Check: Kernel parameter for "ip_local_port_range"
Also install cvuqdisk-1.0.9-1.rpm for ocr block device sharedness check otherwise this check will fail.

If ntp service is not used for time synchronization remove it, to pass the ntp service check

To fix (if ntp is not used)
mv /etc/ntp.conf /etc/ntp.conf.orig

ntpd            0:off   1:off   2:off   3:off   4:off   5:off   6:off
cluvfy also check for patch 11724953. This is the 2011 April CRS PSU so if this is applied no additional patches are needed.

The full output from the cluvfy check is given below.

11gR2 GI uses a SCAN IP which is a pre-req for the upgrade.

Even though upgrade must be done with the same user new user groups could be created for ASM administration. Using the same DBA and OPER group used for oracle user would give a warning.

Create the new asm admin groups.
groupadd asmadmin
groupadd asmdba
groupadd asmoper
Modify the Oracle user from
id oracle
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),503(oper)

Summary



Until the rootupgrade.sh is run cluster stack is up on all nodes. When rootupgrade.sh is run on one node cluster stack on that node is brought down while other node's clusterware stack remains up and open for use. This way by default the upgrades are rolling upgrades. Once rootupgrade.sh is finished running, cluster stack on the node it was run will be brought up and ready for use while the other node's cluster stack is brought down with the rootupgrade.sh

After rootupgrade.sh has finished on the last node click the OK button on the configuration script dialog. This would start configurations steps which also include the ASM upgrade.

ASM is upgraded in a rolling fashion, each database instance that is using the ASM instance being upgraded will be brought down automatically before the ASM upgrade and will be started once ASM is upgraded. Following could be observed on the ASM alert log

The 11gR1 srvctl must be used to administer the database. Using the 11gR2 srvctl from the GI home would throw the following error

Next step is to upgrade the RAC, and this will be done as an out of place upgrade.
It is possible to upgrade the software and database at the same time.
Actions For DST Updates When Upgrading To Or Applying The 11.2.0.3 Patchset [ID 1358166.1] gives details on timezone upgrade information for 11.2.0.3. In this upgrade path (11.1.0.7 -> 11.2.0.3) there's no need to apply any patches beforehand but after upgrade it's advised to ugprade the timezone. This could be done during DBUA exeuction by selecting the upgrade timezone option. Current timezone is
SQL> SELECT version FROM v$timezone_file;

   VERSION
----------
         4
If there are lot of em console related files in $ORACLE_HOME/hostname_instance/sysman/emd/upload/ file copying could take long time.

Execute runInstaller
Select all nodes
New location for out of place upgrade
RAC admin with same OS groups
Summary



Once the root.sh is run and OK button is clicked DBUA runs and database upgrade starts. For the cluster database all instances are shutdown and upgrade continues only on one node with one instance. At the end of the upgrade all instances are started.
Upgrade timezone with database upgrade.

Upgrade result
Once the database is upgraded RAC upgrade concludes.

Once the upgrade is finished uninstall 11gR1 clusterware home and database software.

Post upgrade notes.

remote_listener                      string      LISTENERS_RAC11G1, rac-scan:1521
Even though 11gR1 RAC had Jan 2012 PSU applied and _external_scn_rejection_threshold_hours set it was commented during upgrade and was not present after the upgrade.

After the upgrade database service will not work with FCF create an application service.
