WebLogic Console - No application files exist when redeploying application

Question

When stopping/starting a deployment via the WebLogic Admin console, sometimes we get the following error:

Unable to access application source information in '/opt/product/oracle/local/managedservers/mydomain/servers/serverA/stage/apputil/apputil.war' 
for application 'apputil’. 
The specific error is: [Deployer:149158] No application files 
exist at '/opt/product/oracle/local/managedservers/mydomain/servers/serverA/stage/apputil/apputil.war'

Yet, if I stop and start the managed server, the deployment appears to come back.

My question is, WHY do these war files disappear from the managed server seemingly randomly, while the server is running? This typically happens after we haven't touched a deployment for some time (6 months). Other war files for other deployments are there. It does not affect the running of the app, until we try to stop/start it.

This is what the filesystem looks like before and after.

[oracle@serverA stage]$ pwd;ls -alstr

Restart managed server here...

[oracle@serverA stage]$ ls
appdmin  app-crypto-util  appsm  apputil

Answer 1

This may happen when AdminServer & Managed Server are in different machines, or the war is being sent from a different machine to AS.

use arguments: -remote -upload

i.e.:

java weblogic.Deployer -adminurl t3://200.10.10.125:7001 -verbose -username weblogic -password welcome1 -deploy -targets WLCluster -name sample -remote -source sample.war -upload

I had -remote. Deploy was successful after adding -upload. Thanks – Stanchion

Answer 2

Referring to the stage directory modification date, it appears this dir is created/edited when an event occur, maybe by a script, and if it is the case, the problem should come from that script when copying apps wars.

So in my POV when stopping a deployment, maybe weblogic stop the apputil managed server, wich delete the war from th stage dir, and when starting a deployment after stopping it, it does not start the specified managed server before, and try to redeploy all apps wich cause the exception.

It probably got created when the managed server was restarted. – Nickolenicks

Correct, I know it got created and redeployed after the restart. But I want to know what deleted it (even though it's been running for months). This happens on several of our domains that have infrequent deployments/restarts. – Astereognosis
