Error description

• ABN=0C4-00000010,U=SYSOPR,C=yyyyy.900.RLMC-PEER
  EST,M=CSQJPBE1, LOC=CSQJL002.CSQJDS01+0000xxxxK
  The 0C4 in CSQJDS01 occurs when a queue-manager detects that a
  peer's active log datasets have been defined with SHAREOPTIONS
  less than (2 3), as indicated by message CSQJ250I. An MMSRV
  DISCONNECT is issued by CSQJDS02 after the CSQJ250I message, but
  subsequent processing in CSQJPB01 tries to issue another MMSRV
  DISCONNECT which fails (and results in a S0B0 RC24 dump), and
  then there is an attempt to report the failure via message
  CSQJ104E. However, there is a problem with the parameters
  passed to CSQJDS1B for issuing the message (R7 does not contain
  the address of an LRB4) which results in an 0C4.
  

Local fix

• Ensure all active log datasets for queue-managers in a
  queue-sharing group are defined with SHAREOPTIONS(2,3).
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM MQ for z/OS Version 9       *
  *                 Release 0 Modification 0.                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: In a queue-sharing group, an attempt to *
  *                      read a peer's log dataset created with  *
  *                      incorrect SHAREOPTIONS can generate     *
  *                      abend 0C4 in CSQJDS01 and abends S0B0   *
  *                      or S978 in Media Manager Services.      *
  ****************************************************************
  In a queue-sharing group, if a queue-manager is unable to read a
  peer's log dataset due to incorrect SHAREOPTIONS, then message
  CSQJ250I is issued. However, subsequent processing by CSQJPB01
  incorrectly issues a Media Manager DISCONNECT although a
  DISCONNECT has already been issued, resulting in abend S0B0 RC24
  issued by ICYMMSRV or S978 RC4. There is an attempt to report
  the failing DISCONNECT via message CSQJ104E but there is an
  error in the parameters passed to CSQJDS1B, resulting in an 0C4
  abend in CSQJDS01.
  

Problem conclusion

• CSQJPB01 has been changed to pass the correct parameters to
  CSQJDS1B to issue message CSQJ104E.
  
  CSQJDS01 has been changed to indicate that LOG dataset has
  been disconnected preventing later disconnect attempts.
