PH31439: NON PLANNED TASK MANAGEMENT TASKS NEVER GET DELETED.

APAR status

• Closed as program error.

Error description

• Non Planned Task Management tasks will not go away unless you
  close them. If you never view the console to see these tasks,

  or even OOM in the dmgr if there are too many.
  

Local fix

  Non Planned Task Management tasks will not go away unless
  you close them. If you never view the console to see these
  tasks, you may not realize they are there and they can cause
  slowness or even OOM in the dmgr if there are too many of them.
  

Problem conclusion

• Added the code implementation to make the non-planned task
  management tasks to expire in 24 hours, by default, from the
  time they were created or allow an user to set the expiration
  time in hours using the deployment manager system property
  named
  "com.ibm.websphere.taskmanagement.task.nonPlannedTaskTimeout óÔé
  
  After those tasks expire, they will be removed in the next 24
  hours.
  
  The non-planned tasks created before applying this APAR are
  not impacted by this APAR fix. They still need to be removed
  using an administrative console.
  
  The system property
  "com.ibm.websphere.taskmanagement.task.nonPlannedTaskTimeout"acc
  epts an integer value to configure the amount of hours for a
  non-planned task to expire (in hours). The default value for
  this property is 24 (hours).
  
  Complete the following steps to set the system property on a
  deployment manager process.
  1. In the administrative console, click System administration >
  Deployment manager > Java and process management > Process
  definition > Java virtual machine > Custom properties.
  2. Enter the name of the custom property.
  3. Set the value of the custom property to true.
  4. Click Apply, and save your changes.
  5. Restart the deployment manager where the system property was
  set.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.19 and 9.0.5.7. For more information, see 'Recommended
