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.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.5 that use EJB timers. * **************************************************************** * PROBLEM DESCRIPTION: EJB timer service performs lookup on * * timer database even if application * * server contains only non-persistent * * timer apps. * **************************************************************** * RECOMMENDATION: * **************************************************************** 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 PI50798 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 PI50798 is currently targeted for inclusion in Fix Pack 8.5.5.10 of WebSphere Application Server V8.5.
