PH03083: IEAVESLL ABENDS S0C4 AFTER ITKB CALLS SETLOCK WITH AN INCORRECT PSW KEY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ITKB is setting an incorrect PSW key when calling SETLOCK macro
  to obtain a local lock.
  SETLOCK macro requires PSW key 0, but ITKB calls that macro with
  PSW key 8.
  As the result, IEAVESLL (MVS lock manager module) attempts to
  store into the PSA and abends with S0C4.
  
  This is a forward fit of Tools Base V1.5 APAR PH02253.

  ****************************************************************
  ITKB resource manager routine checks its own control block each
  time the calling task of ITKB terminates, and attempts to
  release resources as needed. If resources need to release, the
  routine obtains local lock using SETLOCK macro.
  
  The cause of this problem is that the routine sets incorrect PSW
  key when calling SETLOCK macro to obtain a local lock. As the
  result, MVS Lock Manager module IEAVESLL called by SETLOCK macro
  terminates with abend S0C4.
  

Problem conclusion

• The ITKB resource manager routine has been modified to set
  correct PSW key before calling SETLOCK macro.
