Hi Nick,
Thanks for your patience in replying.
I restarted my Windows Database instance(Data2) and tried login from the Windows OTM instance(OTM2).
But ended up with the same error(I am not supposed to touch Unix Database.So just tried restart with Windows DB).
My colleague suggests there might be problem with the user access in VPD.
I am attaching the console log files from both Tomcat and WebLogic as text files for your reference.
Tomcat_console.txt Weblogic_console.txt
I really appreciate any suggestions at this point.
Thanks for your time,
Durga
