Review this checklist before upgrading an existing Oracle Grid Infrastructure. A cluster is being upgraded until all cluster member nodes are running the new installations, and the new clusterware becomes the active version.
Table 11-1 Upgrade Checklist for Oracle Grid Infrastructure Installation
|Review Upgrade Guide for deprecation and desupport information that may affect upgrade planning.|
|Patch set (recommended)||Install the latest patch set release for your existing installation. Review My Oracle Support note 2180188.1 for the list of latest patches before upgrading Oracle Grid Infrastructure.|
|Install user account||Confirm that the installation owner you plan to use is the same as the installation owner that owns the installation you want to upgrade.|
|Create a Grid home||Create a new Oracle Grid Infrastructure Oracle home (Grid home) where you can extract the image files. All Oracle Grid Infrastructure upgrades (upgrades of existing Oracle Clusterware and Oracle ASM installations) are out-of-place upgrades.|
|Instance names for Oracle ASM||
Oracle Automatic Storage Management (Oracle ASM) instances must use standard Oracle ASM instance names.
The default ASM SID for a single-instance database is +ASM.
|Cluster names and Site names||Cluster names must have the following characteristics:
|Operating System||Confirm that you are using a supported operating system, kernel release, and all required operating system packages for the new Oracle Grid Infrastructure installation.|
|Network addresses for standard Oracle Grid Infrastructure||
For standard Oracle Grid Infrastructure installations, confirm the following network configuration:
|OCR on raw or block devices||Migrate OCR files from RAW or Block devices to Oracle ASM or a supported file system. Direct use of RAW and Block devices is not supported.
|CVU Upgrade Validation||Use Cluster Verification Utility (CVU) to assist you with system checks in preparation for starting an upgrade.|
|Unset Environment variables||
As the user performing the upgrade, unset the environment variables $ORACLE_HOME and $ORACLE_SID.
Check that the ORA_CRS_HOME environment variable is not set. Do not use ORA_CRS_HOME as an environment variable, except under explicit direction from Oracle Support.
Refer to the Checks to Complete Before Upgrading Oracle Grid Infrastructure for a complete list of environment variables to unset.
|RACcheck Upgrade Readiness Assessment||Download and run the RACcheck Upgrade Readiness Assessment to obtain automated upgrade-specific health check for upgrades to Oracle Grid Infrastructure. See My Oracle Support note 1457357.1, which is available at the following URL:|
|Back Up the Oracle Software Before Upgrades||Before you make any changes to the Oracle software, Oracle recommends that you create a backup of the Oracle software and databases.|
|HugePages memory allocation||Allocate memory to HugePages large enough for the System Global Areas (SGA) of all databases planned to run on the cluster, and to accommodate the System Global Area for the Grid Infrastructure Management Repository.|
