APAR status

• Closed as program error.

Error description

• Customer has an IMSPLEX with two IMS's set to AOS=N and one to
  AOS=F.
  When one of the IMS members left the XCF group and the status
  reassessment was driven, one of the remaining IMS's with AOS=N
  received:
  DFS2088I APPC/OTMA SMQ Enablement inactive. Reason = 020
  The customer finds the RC=20 to be confusing since AOS=N has
  been specifed to begin with.

  ****************************************************************
  When terminating IMS in a shared queues environment, "DFS2088I
  APPC/OTMA SMQ Enablement inactive. Reason = 020." is issued.
  A Reason code of 20 indicates that a member joined the group
  and cannot support APPC/OTMA SMQ Enablement.  This reason code
  does not make sense because no IMS is joining the group.
  
  The failing scenario occurs as follows:
  
  1.  The customer started 3 IMSs with the following options.
         IMS1 with AOS=F
         IMS2 with AOS=N
         IMS3 with AOS=N
  2,  IMS2 is terminated via /CHE FREEZE.
  3.  IMS3 issued MSGDFS2088I APPC/OTMA SMQ Enablement inactive.
      Reason = 020
  
  As IMS3 had AOS=N specified, reason code 032 would be more
  appropriate.  Reason code 32 indicates that AOS=N was specified
  in the DFSDCxxx member.
  

Problem conclusion

• AIDS: RIDS/DCS RIDS/CNTRL DCS CNTRL
    GEN:
  SYSPLEXSQ
  
  *** END IMS KEYWORDS ***
  DFSAOSW0 was modified to set the reason 032 when AOS=N is
  specified.
