PRIMARY

it is passing variable of $PRIMARY_CONF and but the not the $STANDBY_CONF
in the script it is passing the empty value in $STANDBY_CONF
You are setting PRIMARY_CONF in your shell script and your script is seeing the value that you are setting. You are setting STANDBY_CONF in a shell that you are running on COB_HOST; not in the shell execution environment of your script. Therefore, STANDBY_CONF has not been set in the current shell execution environment of your script.

Try changing:
Code:
ssh $COB_HOST << EOF
STANDBY_CONF=`srvctl config database -d $CURRENT_COB | awk -F: '/^Database role/ {match ($0, /[A-Za-z_]*PRIMARY[A-Za-z_]*/); print substr ($0, RSTART, RLENGTH)}'`
echo $STANDBY_CONF
#EOF

(which never should have worked since EOF and #EOF are not the same string) to:
Code:
STANDBY_CONF=$(ssh $COB_HOST << EOF
srvctl config database -d $CURRENT_COB | awk -F: '/^Database role/ {match ($0, /[A-Za-z_]*PRIMARY[A-Za-z_]*/); print substr ($0, RSTART, RLENGTH)}'
EOF
)

and see what happens.
