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.
