This section describes the procedures that must be followed to configure SADTA with Oracle RAC database with ASM. To explain these procedures, it is assumed that the Oracle RAC home directory is /opt/app/oracle/product/11.1.0/db_1/dbs and the database name is hrdb.
Tto configure Oracle RAC database with ASM in Continentalclusters using SADTA:
1.Set up replication between the primary cluster and the recovery cluster.
2.Configure a primary cluster with a single site defined in the Serviceguard cluster configuration file.
NOTE: If Three Data Center (3DC) configuration using P9000 and XP Continuous Access 3DC replication technology is being created, then the primary cluster must be configured as a Metrocluster with two sites.
3.Configure a recovery cluster with a single site defined in the Serviceguard cluster configuration file.
4.Install and configure Oracle Clusterware in both primary cluster and recovery cluster.
5.Install Oracle Real Application Clusters (RAC) software in both primary and recovery cluster.
6.Create the RAC database with ASM in the primary cluster:
a.Configure ASM disk group in the primary cluster.
b.Configure SGeRAC Toolkit Packages for the ASM disk group in the primary cluster.
c.Create the RAC database using the Oracle Database Configuration Assistant in the primary cluster.
d.Configure and test the RAC MNP stack at primary cluster.
e.Halt the RAC database at primary cluster.
7.Configure the Site Controller Package in the primary cluster.
8.Configure the Site Safety Latch dependencies in the primary cluster.
9.Suspend the replication to the recovery cluster.
10.Configure the identical ASM instance at the recovery cluster.
NOTE: Step 10 is required only for Oracle 11g R1 and 10g R2. Step 10 is no longer required for Oracle 11g R2.
11.Set up the identical RAC database at the recovery cluster.
12.Configure the Site Controller Package in the recovery cluster.
13.Configure the Site Safety Latch dependencies in the recovery cluster.
14.Resume the replication to the recovery cluster.
15.Configure Continentalclusters.
16.Configure Continentalclusters recovery group.
17.Start the Disaster Tolerant RAC Database in the primary cluster.
The subsequent sections elaborate on every of these steps.
Setting up replication
The procedure for setting up replication is identical to the procedure for setting up replication to configure Oracle RAC with SADTA. For more information on setting up replication in SADTA for configuring Oracle RAC database with ASM, see “Setting up replication” (page 44).
Configure a primary cluster with a single site
The procedure for configuring Continentalclustrers with sites for Oracle RAC database with ASM is identical to the procedure for configuring Oracle RAC with SADTA. For more information on configuring Continentalclusters with sites for SADTA, see “Configuring the primary cluster with a single site” (page 44).
