How to Convert Single-Instance Database to RAC Database using Rconfig Utility


Database  : racdb
Instance    : Single Instance
Objective : Converting from Single Instance to RAC Instance using 'rconfig'

Check the Instance:
-------------------------
[oracle@rac1 bin]$ ps -ef | grep pmon
oracle    3759     1  0 17:08 ?        00:00:00 asm_pmon_+ASM1
oracle    8407     1  0 17:36 ?        00:00:00 ora_pmon_racdb

Take backup of Original File:----------------------------------
[oracle@rac1 bin]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/assistants/rconfig/sampleXMLs/

[oracle@rac1 sampleXMLs]$ ls
ConvertToRAC_AdminManaged.xml  ConvertToRAC_PolicyManaged.xml

[oracle@rac1 sampleXMLs]$ cp ConvertToRAC_AdminManaged.xml ConvertToRAC_AdminManaged.xml.bak

[oracle@rac1 sampleXMLs]$ vi ConvertToRAC_AdminManaged.xml
