ln –s /opt/app/oracle/admin/+ASM/pfile/init.ora init+ASM2.ora chown -h oracle:oinstall init+ASM2.ora

chown oracle:oinstall orapw+ASM2

7.Add the ASM instances with the CRS cluster on the recovery cluster. In this example, run the following commands from any node on cluster2:

export ORACLE_SID=”+ASM”

srvctl add asm -n <cluster2_node1> -i “+ASM1” –o srvctl add asm -n <cluster2_node2> -i “+ASM2” –o /opt/app/oracle/product/11.1.0/db_1/

Configuring the Identical RAC Database at the recovery cluster

Complete the following procedure to configure the replica RAC database. To explain this procedure, it is assumed that the database name is hrdb and the instance hrdb1 is the first instance on first node and hrdb2 is second instance on second node of the primary cluster.

Complete the following procedure to configure the identical RAC database:

1.Copy the first RAC database instance pfile and password file from the primary cluster to the first RAC database instance node in the recovery cluster.

In this example, run the following commands from the first node in cluster1: cd /opt/app/oracle/product/11.1.0/db_1/dbs

rcp -p inithrdb1.ora <cluster2_node1>:$PWD

rcp -p orapwhrdb1 <cluster2_node1>:$PWD

The -p option retains the permissions of the file.

2.Setup the first RAC database instance on the recovery cluster. In this example, run the following commands from the first node in cluster2:

cd /opt/app/oracle/product/11.1.0/db_1/dbs chown oracle:oinstall orapwhrdb1

chown oracle:oinstall initrhrdb1.ora

3.Copy the second RAC database instance pfile and password file from the primary cluster to the second RAC database instance node in the recovery cluster. In this example, run the following commands from the second node in cluster1:

cd /opt/app/oracle/product/11.1.0/db_1/dbs rcp -p inithrdb2.ora <cluster2_node2>:$PWD rcp -p orapwhrdb2 <cluster2_node2>:$PWD

The -poption retains the permissions of the file.

4.Set up the second RAC database instance on the recovery cluster. In this example, run the following commands from the second node in cluster2:

cd /opt/app/oracle/product/11.1.0/db_1/dbs chown oracle:oinstall orapwhrdb2

chown oracle:oinstall inithrdb2.ora

5.Create the directory for the database (in this example “hrdb”) that is replicated to the recovery cluster, in the Oracle admin directory.

cd /opt/app/oracle

rcp -r admin/hrdb <cluster2_node1>:$PWD

rcp -r admin/hrdb <cluster2_node2>:$PWD

6.Run the following command at the remote site.

chown -R oracle:oinstall /opt/app/oracle/admin/hrdb

7.Log in at any of the nodes in the remote site using the oracle user credentials. su – oracle

8.Configure a listener for the database on this site using the Oracle Network Configuration Assistant (NETCA).
