Question

I am having a problem with a couple of my linux boot scripts, specifically the ones that start up my Oracle 10g database and my oc4j container.

I have used chkconfig to tell Linux to start the database before the container, however, it seems that the container starts before the database which oc4j does not like at all. I can get to my application(s), however, I have no DB connections. If I restart oc4j everything works just fine.

Is there a way that I can “pause” the start-up of oc4j until the database (and listener) are both started and ready for connections?

Answer 1

Put them in 1 start script?

start listener
start database
start appserver

This is my /etc/init.d/dbora script. Add the call to start OC4J

#!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
ORA_HOME=/app/oracle/product/10.2.0/db_1
ORA_OWNER=oracle
echo $1
if [ ! -f $ORA_HOME/bin/dbstart ]
then
    echo "Oracle startup: cannot start"
    exit
fi
case "$1" in
    'start')
        # Start the Oracle databases:
        # The following command assumes that the oracle login
        # will not prompt the user for any values
        su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
        su - $ORA_OWNER -c $ORA_HOME/bin/dbstart
        su - $ORA_OWNER -c $ORA_HOME/bin/emctl start dbconsole
        ;;
    'stop')
        # Stop the Oracle databases:
        # The following command assumes that the oracle login
        # will not prompt the user for any values
        su - $ORA_OWNER -c $ORA_HOME/bin/emctl stop dbconsole
        su - $ORA_OWNER -c $ORA_HOME/bin/dbshut
        su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"
        ;;
