Clustered EJB Timer cannot recover from suspended data source

in Oracle Weblogic Server (MOSC) 2 commentsAnswered

In WLS 12.1.3.0.0 (RHEL7) I installed a number of EJB clustered timers (like in Doc ID 2021113.1). They run fine. But when I suspend the Data Source and resume it after a short while, only a random few of the timers will automatically resume. The rest comes to a halt to never recover. I did this in order to emulate a database failover.

  • How can my software detect that some of the timers have become inactive?
  • What should the software do in order to recover the timers after they were inactive?


Howdy, Stranger!
