Error while starting weblogic post migration to 55 cu4

[[email protected]]

We migrated from 4.5 to 55 CU4 on Redhat Linux AS4. The database, app as well as the web server are on Linux.

Post migration, we have trouble starting up weblogic. The error message shown in the console.log is

INFO | jvm 1 | 2008/09/17 19:27:17 | <Sep 17, 2008 7:27:17 PM IST> <Error> <J2EE> <BEA-160131> <Error deploying DistanceLookup: with deployment error Caught IOException for path=: /data/product/v55/weblogic/config/gc3domain/./applications/.wlnotdelete/wlap24888/DistanceLookup.jar and nested error java.io.IOException: Error opening file>

This error is displayed for all the JAR files that comprise the GC3App.ear. The GC3App.ear gets extracted during weblogic startup in the temporary folder /data/product/v55/weblogic/config/gc3domain/./applications/.wlnotdelete/wlap24888.

All the JAR files for which we get an error are present in the above mentioned temporary location. We also get an exception later that says (Too many open files).

Is there some limit for the number of open files on linux? Could someone please let us know what the problem could be?

Re: Error while starting weblogic post migration to 55 cu4

The startup scripts provided for WebLogic will increase the number of open files. Ensure that you're running this startup script as root - otherwise it may not have the right permissions to do so.

Also - the .wlnotdelete directory can become corrupt and occasionally needs to be deleted, then WebLogic needs to be restarted.
