PI95068: CPSM S0C4 ASRA ABEND IN METHOD XDW2 UNDER TRANID XDNR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Your CMAS takes an SVC dump, with messages in the log similar
  to the following:
  .
  EYUXL0905E applid ASRA IN XDW2, OFFSET 0000072C
                    PSW=47851000 B349FAB4
  EYUXL0905E INTC=0011 ILC=6 TXCP=0085C400 SCODE=S00C4
             TRAN=XDNR TASK=0012345
  EYUXL0905E Methods=XDW2,XDNR,XLOP
  .
  The PSW indicates that we are NOT in ARMODE at the time. The
  failing instruction is an MVC which believes we should be in
  ARMODE.
  This will happen if an API program has issued an
  .
    EXEC CPSM ORDER BY ( field name )
  .
  against a result set, and for some reason the CMAS must return
  a BUSY response. The internal trace will have an entry for the
  abend itself, preceded with an entry with debug text of BUSY,
  like the following:
  .
  Task  Mtd  Prev Tran Obj Level Pt-ID  Debug
  12345 XDW2 XDNR XDNR DAT Excp     34 BUSY
  12345 XDW2      XDNR     Abend       *Abend*

  ****************************************************************
  When you use WUI to view a resource table or use EXEC CPSM ORDER
  API, method EYU0XDW2 (XDW2 - ORDER result set elements) is
  driven to sort the elements in the result set, and if the last
  order process has not finished yet, XDW2 returns with
  REASON(BUSY). Before the return, it writes an exception trace.
  Unfortunately, the ARMODE is switched off during the trace
  processing, and is not switched on properly after. As a result,
  S0C4 abend occurs in XDW2 when it tries to address some data
  that relies on the ARMODE(ON) or overlay of CICS storage leading
  to unexpected result.
  

Problem conclusion

• Module EYU0XDW2 have been updated to set ARMODE(ON) properly.
