APAR status

  • Closed as program error.

Error description

  • While executing the dmpmqcfg command with client connection
    (-c), MQRC_ENVIRONMENT_ERROR (rc=2012) error is returned, when
     SHARECNV(0) is set on SVRCONN Channel definition used by
    dmpmqcfg.
    
    [root@~]# dmpmqcfg -m QMGR -c default
    AMQ8921E: MQCB call failed with reason code 2012.
    [root@~]#
    

Local fix

  • When executing the  dmpmqcfg with the -c flag, use a SVRCONN
    channel with SHARECNV(1) or greater.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ who uses "dmpmqcfg" to connect to a queue manager
    with client connection (-c) option and the SHARECNV is "0" on
    the SVRCONN channel definition in use.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    dmpmqcfg uses MQ's asynchronous consume feature to retrieve PCF
    responses from the command server. When SHARECNV(0) was set on
    the channel, aysnchronous consume operations are not available,
    and synchronous MQGET calls should be used instead. The dmpmqcfg
    utility failed to handle this scenario correctly, and
    incorrectly attempted an asynchronous operation, resulting the
    in the <span style="background-color:rgb(255, 255,
    255)">MQRC_ENVIRONMENT_ERROR response.</span>
    

Problem conclusion

  • The dmpmqcfg utility has been modified to revert to using MQGET
    API calls if asynchronous consume is not available.
