Hi Barry!
We use the Oracle supplied program tnsping
as in the following shell script snippet :
---------------------------------------------------------
#!/bin/sh
PATH=/bin:/usr/bin:/$ORACLE_HOME/bin
export PATH
# get SQL*NET alias from first argument or use ORCL as default
oradb=${1:ORCL}
if $ORACLE_HOME/bin/tnsping $oradb >/dev/null 2>&1
then
echo "database $oradb is up"
else
echo "database $oradb is down ( tnsping returned $?)"
fi
---------------------------------------------------------
Hope this helps,
Andreas
