Verifying the cluster


Verifying the cluster
Prev	Performing post-upgrade tasks	Next

Run the SF Oracle RAC script-based installer or the Web-based installer to verify the functional health of the cluster.

The installer performs the following checks on each node:

Verifies that SF Oracle RAC is installed.
Verifies that the Oracle process daemon (oprocd) is not running.
Verifies that the Veritas libraries (ODM and VCSMM) are linked with the Oracle RAC libraries.
Verifies whether the tunables for LLT/VCSMM tunables are set correctly.
Verifies that the CSSD resource is configured under the CVM service group.
Verifies whether the specified Oracle user has read permissions on the /etc/llttab and /etc/llthosts files.
Verifies that both LLT and Oracle Clusterware/Grid Infrastructure have identical node information.
Verifies that the Oracle RAC database version is the same on all nodes in the cluster. The check fails if the version or patchset information varies across nodes.

For information on resolving issues that you may encounter during the checks, see the Veritas Storage Foundation for Oracle RAC Administrator's Guide, Chapter: Troubleshooting SF Oracle RAC, Section: Troubleshooting installation and configuration check failures.

The installer skips the following checks when LLT is configured over UDP:

LLT links' full duplex setting
LLT link jumbo frame setting (MTU)
LLT links' cross connection
LLT links' speed and auto negotiation settings

To verify the cluster using the script-based installer

Start the SF Oracle RAC installer:

# cd /opt/VRTS/install

# ./installsfrac -configure galaxy nebula

Select the option SF Oracle RAC Installation and Configuration Checks.

1)  Configure SF Oracle RAC sub-components
2)  SF Oracle RAC Installation and Configuration Checks
3)  Prepare to Install Oracle
4)  Install Oracle Clusterware/Grid Infrastructure and Database
5)  Post Oracle Installation Tasks
6)  Exit SF Oracle RAC Configuration
Choose option: [1-6,q] (1) 2

Enter y to confirm that Oracle RAC is installed on the nodes.

Note:

The installer tries to discover the location of the Oracle Clusterware/Grid Infrastructure home directory from the Oracle inventory. If the installer discovers the information, it displays the information.

Enter the full path of the Oracle Clusterware/Grid Infrastructure home directory.

Note:

The installer verifies the path information and re-prompts if the path is incorrect.

Enter the full path of the Oracle RAC database home directory.
