Moving SPFILE from file system to ASM (ORACLE RAC11g)
- There are two nodes in oracle RAC database [rac1] and [rac2]
- Below tasks has to be executed from the first node [rac1]
1. Create spfile in ASM “+RACDB_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'; #Or simply: SQL> create pfile from spfile File created. SQL> create spfile='+RACDB_DATA' from pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora'; File created. SQL> exit
2. New spfile has been created in ASM
[grid@rac1 ~]$ asmcmd ASMCMD> ls RACDB_DATA/racdb1/spfile* spfileracdb1.ora ASMCMD> exit
3. Modify initracdb11.ora on rac1 and initracdb12.ora on rac2 files to point to location in ASM
[oracle@rac1 dbs]$ echo "SPFILE='+RACDB_DATA/racdb1/spfileracdb1.ora'" > /u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora [oracle@rac1 dbs]$ ssh rac2 "echo \"SPFILE='+RACDB_DATA/racdb1/spfileracdb1.ora'\" > /u01/app/oracle/product/11.2.0/db_1/dbs/initracdb12.ora"
4. Update OCR with new SPFILE location
[oracle@rac1 dbs]$ srvctl modify database -d racdb1 -p +RACDB_DATA/racdb1/spfileracdb1.ora
5. Rename any existing spfiles in $ORACLE_HOME/dbs
[oracle@rac1 dbs]$ mv /u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb11.ora /u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb11.ora_bak [oracle@rac1 dbs]$ ssh rac2 "mv /u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb12.ora /u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb12.ora_bak"
6. Restart all instances to switch to new SPFILE
[oracle@rac1 dbs]$ srvctl stop database -d racdb1 [oracle@rac1 dbs]$ srvctl start database -d racdb1 [oracle@rac1 dbs]$ srvctl status database -d racdb1 Instance racdb11 is running on node rac1 Instance racdb12 is running on node rac2
7. Connect to the database and verify spfile parameter:
[oracle@racdb1 dbs]$ <strong>connect / as sysdba</strong> SQL> SHOW parameter spfile NAME TYPE VALUE ------ ----------- ------------------------------ spfile string +RACDB_DATA/racdb1/spfileracdb 1.ora
Cheers!!
