APAR status

• Closed as program error.

Error description

• Disabling the auto start option of a running application
  results in immediate 404s for that application from proxy or
  on-demand router (ODR) due to invalid ond-demand configuration
  (ODC) handling.
  
  A trace shows the ODC removing the application:

  ODC was not reflecting correct Tree contents when the Auto
  start option of an application was modified in the
  administrative console. This led to skipping of application
  reads resulting in 404 errors.
  

Problem conclusion

• To prevent 404 errors from occurring ODC changes were made to
  read application contents correctly in the event of an Auto
  start modification.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.1.  Please refer to the Recommended Updates
