    display chs(channel name) provides the version of MQ Client being used.

    look for attribute `RVERSION` 

    If the client version displays 0000000 then it is MQ 7 and lower.

    Attribute RAPPLTAG will display the application name; java will have .jar if C the application name.

    dis chs(TLS.TEST) RVERSION
AMQ8417I: Display Channel Status details.
   CHANNEL(TLS.TEST)                       CHLTYPE(SVRCONN)
   CONNAME(127.0.0.1)                        CURRENT
   STATUS(RUNNING)                         SUBSTATE(RECEIVE)
   RVERSION(09030401)

    You can reference this document

    In addition to RVERSION, also look at RPRODUCT which will show you whether its a C client or a Java Client etc.

    Full set of values shown here.

    This blog post has more details too.

    Cheers,

    Platform?

    On Distributed, it is in the records written to SYSTEM.ADMIN.ACCOUNTING.QUEUE. Which is easy to see if you use amqsmon or amqsevt to format the records.

    I don't believe it is in the SMF 116 records however.

    Hi Frank,

    Yes - have a read of this blog post: IBM MQ Little Gem #44: Discovering old client versions

    which covers distributed platform Accounting.

    Unfortunately, on z/OS, although the RAPPLTAG is included in SMF 116 channel accounting, the RPLATFORM and RVERSION are not.

    Cheers,
    Morag

    Additional information to SMF 116 Channel accounting data records :

    Field qcstcnnm shows you the connection name which leads you to the machine where the client connects from.
