Hi I've been looking for some details on EJB Timers and retries... maybe someone can help me out on the below?
- WebSphere has default an unlimited number of retries with a 300 sec (5 min) interval. - Assume we have a timer that triggers every half hour and that it at some point fails (lets assume 1 clock for the example below) - Only thing I can find the EJB JSR318 EJB 3.1 is: - "If the container-managed transaction is rolled back, the container retries the timeout." and - "The container must retry the timeout after the transaction rollback." and - "If the transaction fails or is rolled back, the container must retry the timeout at least once." Questions - Are all details around retries implementation specific? How does OpenEJB handle it? - Assume that the timer tasks all fail before say 1:30, will I then see the following scenario?? - 1:00 - Timer due to @Schedule expression => Fails - 1:05 -> 1:25 (every 5 minutes) - Timer due to retry => Fails - 1:30 - Timer due to @Schedule expression => Succeed - 2:00 - Timer due to @Schedule expression => Succeed - ... and so on... - Or might the Timer trigger twice (or twice within a short timeinterval around) 2:00 ? - Will the retry of the Timer stop as soon as the Timer not fails regardless of wether it was triggered as a result of a retry or a normal @Scheduler? -- Med vänlig hälsning / Best regards Lars-Fredrik Smedberg STATEMENT OF CONFIDENTIALITY: The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the address(es) and may contain confidential or privileged information.
