Sigh. Your InstantDB database is corrupted (a common occurance, which is why we stopped using it in WebSphere products). You can either try running the PNS on another database like DB2, or (which may be easiest) remove the WebSphere Test Environment Feature and then Re-add it, which will zap and then restore the database.

Thanks for your suggestion. I did try reintalling VAJ and readding "WEBSPHERE Test environment", I didnot work. Problem was, I had an unwanted JNDI jar in the classpath, which was somehow clashing with the PNS. When I removed this JNDI jar, It worked fine. Errors in PNS for Medium level tracing was also misleading! Even now, I am getting the errors, but I able to create datasource, start PNS and able to get data from the database using SQL query.
