APAR status

  • Closed as program error.

Error description

  • A queue manager is running with SSL enabled SDR and SSL enabled
    CLUSSDR channels in running state.
    When "REFRESH SECURITY TYPE(SSL) SSL" command is issued,  the
    SSL enabled SDR channels that were running
    get stuck in STARTING state.
    
    The following FFSTs with rrcE_CHANNEL_NOT_FOUND error in MQM
    Trace history may be seen:

Local fix

  • When the SDR channels are stuck in STARTING, there are two
    methods to get them started:
    
    1. Using runmqsc or equivalent MQ Explorer alternative:
    STOP CHL(MY.SDR.CHL) STATUS(INACTIVE)
    ALTER QL(XMITQ) NOTRIGGER
    ALTER QL(XMITQ) TRIGGER
    
    2.  A simple "START CHL(MY.SDR.CHL)" will also get the channel
    back up and in RUNNING status.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users issuing "refresh security type(ssl)" command when SSL
    enabled SDR and SSL enabled CLUSSDR channels are in running
    state.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The channel failed to start because the amqrcmla process was not
    able to obtain the correct channel definition to restart, due to
    an
    incorrect internal query to obtain the channel definition.
    

Problem conclusion

  • The MQ refresh security routines have been modified to correctly
    query the channel definition when refreshing SSL.
