Called an Oracle Local Registry (OLR): each node in a cluster has a local registry for node-specific resources

Oracle Cluster physical configuration requirements and restrictions

Oracle Clusterware 10g/11g process details

Installing php-mysql on the SQL node in the Cluster prompts a conflict.

Test 1: Simulate the loss of an olr exception:

First, set the olr renam
[Root @ vmrac2 cdata] # mv vmrac2.olr vmrac2.olr. bak

Then try to start crs
[Root @ vmrac2 cdata] # crsctl start crs
CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.

Then, observe the log output of the cluster alert log:

[Grid @ vmrac2 vmrac2] $ tailf alertvmrac2.log
