Sun Cluster Data Service for Oracle Parallel Server/Real Application Clusters Guide for Solaris OS

Node Failures and Recovery Procedures

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. After you have corrected the problem, reboot the node. See the Sun Cluster System Administration Guide for Solaris OS for more information.



Note –

When you install this data service, ensure that you complete all steps of all procedures that precede installing the Oracle RDBMS software and creating 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. After you have corrected the problem, you must reboot the nodes. The procedures that you must complete are listed in Table 2–1.
