Moving Spfile From File-System To ASM

1. Create spfile in ASM "+DATA" disk group :

SQL> connect / as sysdba

SQL> show parameter spfile

NAME TYPE VALUE
------- ------- ------------------------------
spfile string /u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb11.ora

SQL> create pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora' from spfile='/u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb11.ora';

SQL> create pfile from spfile
File created.

SQL> create spfile='+DATA' from pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora';
File created.

SQL> exit

2. Modify initracdb11.ora on node1 and initracdb12.ora on node2 files to point to location in ASM

[oracle@node1 dbs]$ echo "SPFILE='+RACDB_DATA/racdb1/spfileracdb1.ora'" > /u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora
[oracle@node1 dbs]$ ssh node2 "echo \"SPFILE='+RACDB_DATA/racdb1/spfileracdb1.ora'\" > /u01/app/oracle/product/11.2.0/db_1/dbs/initracdb12.ora"

3. Update OCR with new SPFILE location

[oracle@node1 dbs]$ srvctl modify database -d racdb1 -p +RACDB_DATA/racdb1/spfileracdb1.ora

4. Rename any existing spfiles in $ORACLE_HOME/dbs
5. Restart all instances to switch to new SPFILE
6. Check New Location For Spfile .
