JConfiguring Oracle RAC in Continentalclusters in Legacy style
Support for Oracle RAC instances in a Continentalclusters environment
When the primary cluster fails, the clients database requests are served by the support of Oracle RAC instances that are restarted by the Continantalclusters on the recovery cluster. Figure 3 (page 125) is a sample of Oracle RAC instances running in the Continentalclusters environment.
Figure 3 Oracle RAC instances in a Continentalclusters environment
As shown in Figure 3 (page 125), Oracle RAC instances are configured to run in Serviceguard packages. The instance packages are running in the primary cluster and recovered on the recovery cluster upon a primary cluster failure. Figure 4 (page 126) shows a recovery using an Oracle RAC configuration after failover.
Oracle RAC instances are only supported in the Continentalclusters environment for physical replication set up using HP StorageWorks Continuous Access P9000 and XP, HP StorageWorks Continuous Access EVA or EMC Symmetrix Remote Data Facility (SRDF) using an SLVM or Cluster Volume Manager (CVM) or Cluster File System (CFS) or Automatic Storage Management (ASM) for volume management. In Continentalclusters, the Oracle RAC with ASM can be configured using the SADTA. For more information, see “Configuring Oracle RAC database with ASM in Continentalclusters using SADTA” (page 136).
Continentalclusters Oracle RAC support is available for a cluster environment configured with only Serviceguard and SGeRAC (For example, an environment running with Oracle RAC 9i, 10g or 11g).
Starting with Continentalclusters version A.05.01, recovery of an Oracle RAC instance in a cluster environment running Serviceguard and Oracle Clusterware is supported. There is a special configuration required for the environment running both Oracle Clusterware and Serviceguard/Serviceguard Extension for RAC (SGeRAC) for the Continentalclusters RAC instance recovery protection.
For more information, see “Configuring the environment for Continentalclusters to support Oracle RAC” (page 126).
