To test the importance of OLR in Oracle 11g cluster

Called a Oracle local Registry (OLR): Each node in a cluster has a local Registry for node-specific

Test one: Simulate OLR abnormal loss:

Here first will OLR Renam

[Root@vmrac2 cdata]# MV VMRAC2.OLR Vmrac2.olr.bak

And 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.

We then looked at the log output of cluster alert log:
