How to export and import crs resources while migrating Oracle RAC to new server.

Below script generate svrctl add script for database, instance, service and 11G listeners from OCR from current RAC.
Save the result of the script and run it at new RAC.


for DBNAME in $(srvctl config database)
do

# Generate DB resource

srvctl config database -d $DBNAME -a | awk -v dbname="$DBNAME" \
'BEGIN { FS=":" }
$1~/Oracle home/ || $1~/ORACLE_HOME/ {dbhome = "-o" $2}
$1~/Spfile/ || $1~/SPFILE/ {spfile = "-p" $2}
$1~/Disk Groups/ {dg = "-a" $2}
END { if (avail == "-a ") {avail = ""}; printf "%s %s %s %s %s\n", "srvctl add database -d ", dbname, dbhome, spfile, dg }'

# Generate Instance resource

srvctl status database -d $DBNAME | awk -v dbname="$DBNAME" \
'$4~/running/ { printf "%s %s %s %s %s %s\n", "srvctl add instance -d ",dbname, " -i ", $2 ," -n ", $7 }

# Modify instance for 10G - ASM dependency

if [ $(echo $ORACLE_HOME | grep "1020" | wc -l ) -eq 1 ]
then
srvctl status database -d $DBNAME | awk -v dbname="$DBNAME" \

# Listener at 11G Home. 10G listener can't ba added with srvctl.
