I am trying to install Oracle Database 11gR2 database on Oracle Grid 11gR2. I successfully installed Grid without errors. However, when installing the database, I got an OLR Integrity error during the prerequisit Check
OLR Integrity - This test checks the integrity of OLR on the local node.
Expected Value : n/a
Actual Value : n/a
List of errors:
- Permissons of file
"/u01/app/oracle/product/11.2.0/grid/cdata/localhost/localhost.olr" did not match the expected value. [Expected = "0600"; Found = "0660"]
- Cause: Cause of Problem Not Available
- Action: User Action Not Available.
It is strange that the same didn't arise with the Grid Infrastructure installation. Didn't you have warnings at the end of the GI? Have you touched the OLR after GI installation?.
If it is only permission, it can be resolved easly (with chmod 600 /u01/app/oracle/product/11.2.0/grid/cdata/localhost/localhost.olr), but that file must have been created with the proper permission the first time, you need to investigate why it ended that way to be sure the installation is ok.
Please read the note *RAC and Oracle Clusterware Best Practices and Starter Kit (Linux) [ID 811306.1]* to validate that you haven't missed any recommendation.
