Issue

• This script contains following function

exit_idle()
{
        declare -i n=0
        while ps ax | grep $ORACLE_HOME | grep -q -v grep; do
                if [ $n -ge 90 ]; then
                        force_cleanup
                        return 0
                fi
                sleep 1
                ((n++))
        done
        return 0
}

This function does not check for ORACLE_SID. So if there are other other ORACLE instances running from the same ORACLE_HOME script stops here for 90 seconds.

Fortunately force_cleanup() function has required check so it won't actually kill these other processes:

pids=`ps ax | grep $ORACLE_HOME | grep "ora_.*_${ORACLE_SID}" | grep -v grep | awk '{print $1}'`

This causes unnecessary delays to instance failovers.
