PH59367: THE CAPTURING OF QUERY PERFORMANCE DATA OR OF AN ACCELERATOR TRACE FAILS: THE POP-WINDOW TO SAVE THE TRACE IS NOT DISPLAYED

APAR status

• Closed as documentation error.

Error description

• The capturing of query performance data could fail in the sense
  that the pop-up window to finalize the saving of the trace data
  is not displayed and that no data are collected.
  In such a situation a  subsequent retry of the data capturing as
  
  well as an attempt to just collect an accelerator trace will
  also not be successful.
  
  The reason for this issue is a race condition within the trace
  collection itself that can cause this deadlock.
  
  A fix for this issue will be made available with Accelerator
  maintenance level 7.5.12.2.

Local fix

• To overcome the issue, IBM support needs to log on to the
  accelerator.
  The support engineer may find "Trace Collection" tasks hanging.
  A cancellation of the tasks will not be successful.
  A restart of the accelerator server will cure the issue and will
  make the trace collection possible again.
