APAR status

• Closed as program error.

Error description

• The timer service performs a lookup on the timer database for
  both persistent and non-persistent timers which require the
  database tables to be defined for both types of timers.   This
  APAR will provide an alternative to avoid checking the timer
  service database if the application server contains only
  non-persistent timer applications.
  

Local fix

• Define the tables for the timer service database.

  The timer service performs a lookup on the timer database when
  application server contains any EJB timers which require the
  database tables to be defined when using persistent and/or
  non-persistent timers.
  

Problem conclusion

• APAR PI60135 provides an alternative to avoid checking the
  timer service database if the application server contains only
  non-persistent timer applications through setting a system
  property for the EJB Container. The system property is
  named "com.ibm.websphere.ejbcontainer.disablePersistentTimers".
  The property can take the values 'true', 'false' with a
  default of 'false'.
  
  This property disables EJB persistent timers,
  causing any attempts to create or use them to throw an
  exception stating they are disabled.
  
  To set this property, perform the
  following steps:
  1. Open the administrative console.
  2. Select Servers.
  3. Select Application Servers.
  4. Select the server you want to configure.
  5. In the Server Infrastructure area, select Java and
  Process Management.
  6. In the Server Infrastructure area, select Process
  Definition.
  7. In the Additional Properties area, select Java Virtual
  Machine.
  8. In the Additional Properties area, select Custom Properties.
  9. Select the New box.
  10. In the Name entry field, type
  com.ibm.websphere.ejbcontainer.disablePersistentTimers
  11. In the Value entry field, type 'true' to enable, 'false'
  to disable.
  12. Select OK.
  
  APAR PI60135 is currently targeted for inclusion in Fix Pack
  8.5.5.10 of WebSphere Application Server V8.5.
