How to launch a script when starting an Oracle Application Server container?

We have added a JMS componant to our growing application and now whenever one of our OAS containers goes down there are a couple of .lock files that are left behind in our ....../j2ee/<containername>/persistence/ subfolders.

Then once we attempt to bring the container up it pukes on these lock files. It was suggested that we use a script of some sort to delete *.lock files in this folder upon container startup.

I am not seeing any obvious methods of doing that.

Yes we use simple .sh files for startup and shutdown, but we also use DCM off the command line and from ANT deployment scripts as well as going through the web front end for application server control. As such I am not sure where to deal with the problem being as there are multiple entry points where you can perform startups....

Perhaps the best place to put it is in the shutdown script(s):

(This is Korn shell)
******************
sleep 15
if [[ -n `ls <your_path_to>/*lock` ]]
then
        for i in `ls -l <your_path_to>*lock|cut -c55-`
          do
                rm -f $i
          done
fi
********************

Yes but as I mentioned there is more than one way to skin a cat in this case. We are building and testing our j2ee application and as such there are frequent shutdowns of the containers that do not come from the shutdown scripts. So ideally this could be done on startup...

In unix - there's typically at least 3 ways to skin that cat, but it's your box.  You can put the script where you like.

You can configure start and stop event scripts in opmn. See the metalink note "274088.1 -How to use the pre-start and pre-stop event scripts with AS10g on UNIX"

https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=274088.1

The idea is that you can execute any script using the event-scripts tag in opmn.xml.

<event-scripts>
        <pre-start path="/home/ias9041/pre-start.sh"/>
       <pre-stop path="/home/ias9041/pre-stop.sh"/>
</event-scripts>

ah most excellent, I will look into that, thank you. I expect this is stuff a fully qualified admin would know but we currently have a gap in our expertise over here.
