RE: Determining Oracle status

[JOE TESTA]

tnsping does not check for database up, its nothing more than a ping to a listener, they only sure way to see if the database is up is to connect to it.   and its still that way in 9i.   joe   >>> [EMAIL PROTECTED] 09/18/01 02:40PM >>> 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 > ---------- > Von:     Barry Deevey[SMTP:[EMAIL PROTECTED]] > Gesendet:     Dienstag, 18.
