Move SPFILE from one ASM diskgroup to another (ORACLE RAC)

##
## "Move" spfile from:
##    +OLDLOC/DBNAME/spfileDBNAME.ora
##  to:
##    +NEWLOC/DBNAME/spfileDBNAME.ora
##

## NOTE:
##   in this example there are FOUR nodes:
##      rac1
##      rac2
##      rac3
##      rac4


## run all steps from first node
##
## "copy" spfile to +NEWLOC
sqlplus /nolog
connect / as sysdba
create pfile='/u01/app/oracle/admin/DBNAME/scripts/init_new.ora' from spfile='+OLDLOC/DBNAME/spfileDBNAME.ora';
create spfile='+NEWLOC/DBNAME/spfileDBNAME.ora' from pfile='/u01/app/oracle/admin/DBNAME/scripts/init_new.ora';
exit

## modify init*.ora files to point to new location
##
echo "SPFILE='+NEWLOC/DBNAME/spfileDBNAME.ora'" > /u01/app/oracle/product/10.2.0/db_1/dbs/initDBNAME1.ora
ssh rac2 "echo \"SPFILE='+NEWLOC/DBNAME/spfileDBNAME.ora'\" > /u01/app/oracle/product/10.2.0/db_1/dbs/initDBNAME2.ora"
ssh rac3 "echo \"SPFILE='+NEWLOC/DBNAME/spfileDBNAME.ora'\" > /u01/app/oracle/product/10.2.0/db_1/dbs/initDBNAME3.ora"
ssh rac4 "echo \"SPFILE='+NEWLOC/DBNAME/spfileDBNAME.ora'\" > /u01/app/oracle/product/10.2.0/db_1/dbs/initDBNAME4.ora"

## modify OCR with new SPFILE location
##
export ORACLE_HOME=$CRS_HOME
export PATH=$ORACLE_HOME/bin:$PATH
srvctl modify database -d DBNAME -p +NEWLOC/DBNAME/spfileDBNAME.ora

## bounce ALL instances to switch to new SPFILE
##
export ORACLE_HOME=$CRS_HOME
export PATH=$ORACLE_HOME/bin:$PATH
srvctl stop database -d DBNAME
srvctl start database -d DBNAME

## all services will be down because DB got bounced -- restart it
##
srvctl start service -d DBNAME



## drop old spfile
##
export ORACLE_HOME=/u01/app/oracle/product/10.2.0/asm
export PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_SID=+ASM1
sqlplus /nolog
connect / as sysdba
ALTER DISKGROUP OLDLOC DROP FILE '+OLDLOC/DBNAME/spfileDBNAME.ora';
exit

## verify "old" spfile is gone from OLDLOC
##
