RE: [JBoss-user] Farm drops app on redeploy

I rewrote the farming service in 3.2 and beyond. Should solve a lot of issues. The farming service in 3.0.x is a bit limited.

Sorry,

Bill

Thanks! That’s just what I was looking for. At the moment I have disabled formal clustering and am simply running the application as a collection of independent loadbalanced nodes, but this will come in handy when I’m feeling masochistic and start playing with farming again :-)

Thanks,

As I see it, you have an EAR deployer that you want to make dependant on your datasource?

I've just tried editing my conf/jboss-service.xml, before it was:


<mbean code="org.jboss.deployment.EARDeployer" name="jboss.j2ee:service=EARDeployer">
</mbean>

Now it's:


<mbean code="org.jboss.deployment.EARDeployer" name="jboss.j2ee:service=EARDeployer">
<depends>jboss.jca:service=LocalTxCM,name=DefaultDS</depends>
</mbean>

Not that I've had any troubles before - but imho this should have the effect that your EAR deployer depends on your datasource (this way you make a dependancy from "conf/" into "deploy/" - which might not be that nice - but that's just aesthetics). From my feeble attempts it seems to have the correct effect on my system - but that might just be coincidental.

I haven't played that much around with this setup, but one effect might be that if you edit the xml for your datasource, and hence redeploy your connection pool, then your EAR deployer gets redeployed, and with it, all your EAR's

Subject: [JBoss-user] Farm drops app on redeploy

Hi! I have a JBoss (3.0.2/tomcat 4.0.4) cluster (right now just 2
machines) which is farmed. For the most part, farming works (although
it seems to like to pick up my EAR before the oracle-service.xml which
provides the data source), but I just started experiencing a peculiar
bit of behavior.

A normal deploy from scratch farms out my EAR just fine; it's picked up
by both JBoss instances and all is well.

If I redeploy the application, it installs to both instances and then is
immediately removed from both instances (!)

What may have something to do with this is that my app now takes a long
time (a couple minutes) to load and initialize. Back when it was almost
instantaneous, I didn't notice this problem.

Is there something I can do about this? Also, is there some way of
forcing my EAR to deploy _after_ my oracle-service.xml?

Thanks,
Jeff Schnitzer
