PH03853: CPSM REXX API GET WITH OPTION NOWAIT. RECEIVE WITH OPTION DELAY WAITS FOR TOTAL DELAY PERIOD DESPITE DATA BEING RETURNED BEFORE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CPSM Async API REXX. In the exec, a GET with the NOWAIT option
  is coded.
  Later, a RECEIVE with DELAY(5) attribute is coded. This code
  works, but the REXX program waits for 5 seconds regardless of
  the output becoming available during the delay period.
  The manuals says "If output becomes available during the delay
  period, control returns to the processing thread."

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of CPSM V5R4M0 and V5R5M0.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: A batch job uses CPSM API to issue      *
  *                      EXEC CPSM REVEIVE, specifying 'DELAY'   *
  *                      option. The behavior for this batch job *
  *                      is inconsistent with documented         *
  *                      behavior.                               *
  ****************************************************************
  The method ABAG processes the RECEIVE command, which uses the
  macro STIMER to wait for the time specified in the DELAY option
  to expire. The method ABAG is in a wait state until the time
  expires. The wait won't end when the result becomes available
  within specified DELAY time.
  

Problem conclusion

• Method ABAG has been updated and when there is a result return
  it will be processed immediately without waiting for the time to
  expire.
