Standalone Standby Database Creation for 2 node RAC in Oracle 11g

Environment.

Primary 2 Node Database RAC
1. Instance rac1 host rac1
2. Instance rac2 host rac2

Standby Database STBY
Instance stby1 host stby


At Standby, I have 3 disks avaiable, so I created the new Disk group FRA as identical to Primary database.

select a.name,a.state,b.name,b.label,b.path
from v$asm_disk b, v$asm_diskgroup a
where a.GROUP_NUMBER=b.GROUP_NUMBER;

SQL> select label from v$asm_disk;

SELECT group_number, name, compatibility, database_compatibility, ALLOCATION_UNIT_SIZE/1024/1024 "AU_Size in MB" FROM v$asm_diskgroup;

At Standby Database server create a temporary listener, listening to standby instance stby1.

[root@stby bin]# ./srvctl add listener -l listener_standby -p "TCP:1522" -o /u01/app/oracle/product/11.2.0/dbhome_1/

Make Static entry for Standby database.
