Hello!
Our check procedure on TRU64 UNIX is:
checkmasterdaemon
if [ $? -eq 1 ]; then
# Try to connect to postgres by selecting tables
TABELLEN=`/pg/postgresql-7.4.3/bin/psql -h postgres -c 'select datname from
pg_database' postgres postgres 2>/dev/null`
if [[ "X$TABELLEN" = "X" ]];then
echo "check failed for postmaster"
exit 1
else
# echo "postmaster is running"
fi
else
echo "check failed for postmaster"
exit 1
fi
where :
checkmasterdaemon () {
MASTER_PID=$(getmasterpid)
if [ "X$MASTER_PID" = "X" ]; then
#echo "Postmaster is not running"
ret=0
else
PS_OUT=`ps -o comm,pid -p "${MASTER_PID}"`
PID=`echo $PS_OUT | awk '/postgres/ {print $4}'`
#echo $PID
if [ "X$MASTER_PID" != "X$PID" ]
then
#echo "Postmaster (${MASTER_PID}) does not exist (any more)"
ret=0
else
ret=1
fi
fi
return $ret
}
getmasterpid () {
if [[ -r ${PIDFILE} ]]
then
MASTER_PID=`head -n 1 ${PIDFILE}`
echo $MASTER_PID
else
echo ""
fi
}
