Error description

• The Operations Console EngMonApp process stops and can not be
  restarted, showing the log error: "Unable to delete the event
  run file..."Conversely, the EngMonApp process will start up, but
  will loop round forever, not processing any event files, with a
  log error: "The events subdirectory that previously existed no
  longer exists: ..."
  
  Both these issues are caused by file permission issues on the
  Server/DSODB/event directory and subdirectories.
  These directories should be readable and writeable by the
  datastage user group, and jobs should be run by a member of that
  datastage user group.
  If jobs are run by another user then they can create event
  subsdirectories or event files that the EngMonApp does not have
  access to. This can cause EngMonApp to stop, because it cannot
  delete any event files.
  
  If, for some reason the directories do not have the permissions
  as installed, and EngMonApp does not have sufficient access to
  the directories then it can start up but loop forever trying to
  process files that it does not have access to.
  
  Both of these cases are invalid as the files should have the
  installed permissions and jobs should be run by a user in the
  datastage group.
  However, for the first problem, EngMonApp should be changed to
  help the user determine what the actual problem is by displaying
  the current users group permissions and the permissions on the
  files.
  For the second problem EngMonApp shoul dbe changed to avoid
  looping forever and to log a more suitable error message to
  determine the problem.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of Operations Console with non-standard users running jobs
  such that the datastage user group does not have access to the
  created event files.
  ****************************************************************
  PROBLEM DESCRIPTION:
  If the datastage user group does not have access to read and
  write all event directories and files then the Ops Console
  EngMonApp application will not start or will not run correctly.
  In some cases EngMonApp will fail immediately and in some cases
  it will go into a tight loop creating very large log files. This
  is because it cannot process and then delete the event files.
  ****************************************************************
  RECOMMENDATION:
  Apply patch or fix pack.
  ****************************************************************
  

Problem conclusion

• EngMonApp still cannot run successfully without appropriate
  access permissions for the datastage user group, but it will now
  always fail rather than running in a tight loop and will include
  more information in the logs to help determine the problem.
