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.
