Resolve Duplicate CRS Cluster Name in EM Grid Control - (Grid Control 10g) (11-August-2010)
During the installation of Oracle Clusterware, you are asked to specify a name for the cluster. If you're like me, you may opt to keep the CRS Cluster Name set to its default value of "crs". Even when configuring a second or third Oracle RAC within an organization, we many times simply leave the cluster name for the new clusters set to their default value of crs. Although I believe it is bad practice to configure multiple Oracle RAC clusters with the same CRS cluster name, it doesn't necessarily cause any conflicts given these clusters don't interact with each other. The clustered databases work independently from each other without incident. That is, until you register multiple clustered databases with the same CRS cluster name in Oracle Enterprise Manager Grid Control! An issue can arise when multiple Oracle RAC clusters with the same CRS cluster name are registered as targets in EM Grid Control. While not causing a problem with the cluster itself, it does cause EM Grid Control to think both clusters are the same. The following article will explain the steps used to change the EM cluster target name(s) in Grid Control from their default name of "crs" to avoid conflict with other cluster targets. In this article, a new EM cluster target name will be created in EM Grid Control for two Oracle RAC database environments that were registered in EM Grid Control with the same EM cluster target name.
