MarkView Application Server - The WebLogic Application Server does not start and an error is encountered containing the text “The persistent file store "WLS_DIAGNOSTICS" cannot open file WLS_DIAGNOSTICS000000.DAT”.

Summary

12038

Applies To

  • ERP System: Oracle, SAP
  • MarkView Version: All

Behavior

  • The WebLogic Application Server cannot start the MarkView Managed Server and an error is encountered in the log file 'markview_server.out' containing the text “The persistent file store 'WLS_DIAGNOSTICS' cannot open file WLS_DIAGNOSTICS000000.DAT”.

Cause

  • This error has been known to occur when the MarkView Managed Server did not previously shutdown cleanly and is trying to start using corrupt cache files.

Resolution

  • To resolve the issue, the corrupt cache file listed in the markview_server.out file should be deleted before attempting to restart the MarkView Managed Server:
    • The file WLS_DIAGNOSTICS000000.DAT can normally be found in the location
      $WL_HOME/../user_projects/domains/markview/servers/markview_server/data/store/diagnostics.
  • Several other corrupt cache files can also sometimes prevent the MarkView Managed Server from starting. If so, these are also reported in the markview_server.out file and include:
    • $WL_HOME/../user_projects/domains/markview/servers/markview_server/data/store/default/_WLS_MARKVIEW_SERVER000000.DAT
    • $WL_HOME/../user_projects/domains/markview/servers/markview_server/tmp/markview_server.lok
    • $WL_HOME/../user_projects/domains/markview/servers/markview_server/data/ldap/ldapfiles/Embedded.lok
  • Similar issues can occur with the WebLogic Admin Server (which manages the MarkView Managed Server) being unable to start. Problem cache files are listed in the AdminServer.log. The corrupt files should be deleted and then the Weblogic Admin Server should be restarted. The corrupt cache files may be any of the following:
    • $WL_HOME/../user_projects/domains/markview/servers/AdminServer/tmp/AdminServer.lok
    • $WL_HOME/../user_projects/domains/markview/servers/AdminServer/data/ldap/ldapfiles/EmbeddedLDAP.lok
    • $WL_HOME/../user_projects/domains/markview/servers/AdminServer/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
    • $WL_HOME/../user_projects/domains/markview/servers/AdminServer/data/store/default/_WLS_ADMINSERVER000000.DAT
