Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters

Node Failures and Recovery Procedures

If a node fails in an Oracle Parallel Server/Real Application Clusters environment, you can configure Oracle clients to reconnect to the surviving server without the use of the IP failover that Sun Cluster failover data services use. The Sun Cluster 3.1 Concepts Guide document describes this failover process. In an Oracle Parallel Server/Real Application Clusters environment, multiple Oracle instances cooperate to provide access to the same shared database. The Oracle clients can use any of the instances to access the database. Thus, if one or more instances have failed, clients can connect to a surviving instance and continue to access the database.


Note –

If a node fails, boot the node into maintenance mode to correct the problem. See the Sun Cluster 3.1 System Administration Guide for more information.



Note –

When you install this data service, ensure that you complete all steps of all procedures that precede How to Install the Oracle RDBMS Software and Create Your Oracle Database before you reboot the nodes. Otherwise, the nodes will panic. If the nodes panic, you must boot into maintenance mode to correct the problem.
