to configure replication. After configuring replication in your environment, configure the replica RAC database.

For example, complete the following procedure to prepare the replication environment:

1.Ensure the replication is in PAIR state at the replication Target Disk Site node. The STATUS field should have PAIR value.

In this example, run the following command from the SJC_1 or SJC_2 node: pairdisplay -g hrdb_devgroup

This command is an illustration for Metrocluster with Continuous Access for P9000 and XP. This command will be different for Metrocluster with Continuous Access EVA and Metrocluster with EMC SRDF.

2.Perform a replication swap take over from the Target Disk Site node.

In this example, run the following command from the SJC_1 or SJC_2 node. horctakeover -g hrdb_devgroup -t 360

3.From the CVM master node at this site, import the disk groups used by RAC database. vxdg -stfC import hrdbdg

vxdg -stfC import flashdg

4.Create the Serviceguard Disk Group MNP packages on this site. cfsdgadm add hrdbdg sjc_hrdb_dg all=sw SJC_1 SJC_2 cfsdgadm add flashdg sjc_flash_dg all=sw SJC_1 SJC_2

5.Activate the RAC database disk groups in the CFS sub-cluster. cfsdgadm activate hrdbdg

cfsdgadm activate flashdg

6.Create the mount point directories for the RAC database cluster file systems. mkdir /cfs

chmod 775 /cfs mkdir /cfs/rac mkdir /cfs/flash

7.Create the Mount Point MNP packages for the RAC database cluster file systems. cfsmntadm add hrdbdg rac_vol /cfs/rac sjc_hrdb_mp all=rw SJC_1 SJC_2

cfsmntadm add flashdg flash_vol /cfs/flash sjc_flash_mp all=rw SJC_1 SJC_2

8.Mount the cluster file systems in this CFS sub-cluster. cfsmount /cfs/rac

cfsmount /cfs/flash

Configuring the Replica RAC Database

Complete the following procedure to configure the replica RAC database.

1.Copy the first RAC database instance pfile from the source site to the target site first RAC database instance node.

In this example, copy the RAC database instance pfile from the SFO_1 node to the SJC_1 node.

cd /opt/app/oracle/product/10.2.0/db_1/dbs rcp -p inithrdb1.ora SJC_1:$PWD
