here is the shell script we use to monitor dataguard, it sends mail if there is a gap for more than 20 archive logs..
#set Oracle environment for Sql*Plus
#ORACLE_BASE=/oracle/app/oracle ; export ORACLE_BASE
ORACLE_HOME=/oracle/app/oracle/product/10.2.0 ; export ORACLE_HOME
ORACLE_SID=usagedb ; export ORACLE_SID
PATH=$PATH:/oracle/app/oracle/product/10.2.0/bin
#set working directory. script is located here..
cd /oracle/scripts
#Problem statemnt is constructed in message variable
MESSAGE=""
#hostname of the primary DB.. used in messages..
HOST_NAME=`/usr/bin/hostname`
#who will receive problem messages.. DBAs e-mail addresses seperated with space
DBA_GROUP='[email protected] '
#SQL statements to extract Data Guard info from DB
LOCAL_ARC_SQL='select archived_seq# from V$ARCHIVE_DEST_STATUS where dest_id=1; \n exit \n'
STBY_ARC_SQL='select archived_seq# from V$ARCHIVE_DEST_STATUS where dest_id=2; \n exit \n'
STBY_APPLY_SQL='select applied_seq# from V$ARCHIVE_DEST_STATUS where dest_id=2; \n exit \n'
#Get Data guard information to Unix shell variables...
LOCAL_ARC=`echo $LOCAL_ARC_SQL | sqlplus -S / as sysdba | tail -2|head -1`
STBY_ARC=`echo $STBY_ARC_SQL | sqlplus -S / as sysdba | tail -2|head -1`
STBY_APPLY=`echo $STBY_APPLY_SQL | sqlplus -S / as sysdba | tail -2|head -1`
#Allow 20 archive logs for transport and Apply latencies...
let "STBY_ARC_MARK=${STBY_ARC}+20"
let "STBY_APPLY_MARK= ${STBY_APPLY}+20"
if [ $LOCAL_ARC -gt $STBY_ARC_MARK ] ; then
MESSAGE=${MESSAGE}"$HOST_NAME Standby -log TRANSPORT- error! \n local_Arc_No=$LOCAL_ARC but stby_Arc_No=$STBY_ARC \n"
fi
if [ $STBY_ARC -gt $STBY_APPLY_MARK ] ; then
MESSAGE=${MESSAGE}"$HOST_NAME Standby -log APPLY- error! \n stby_Arc_No=$STBY_ARC but stby_Apply_no=$STBY_APPLY \n"
fi
if [ -n "$MESSAGE" ] ; then
MESSAGE=${MESSAGE}"\nWarning: dataguard error!!! \n .\n "
echo $MESSAGE | mailx -s "$HOST_NAME DataGuard error" $DBA_GROUP
fi
