For information on how we use MQSC commands, see Performing local administration tasks using MQSC commands.

We can issue this command from sources 12CR. For an explanation of the source symbols, see Use commands on z/OS®.

    Usage notes for DISPLAY SYSTEM

    1. DISPLAY SYSTEM returns a report that shows the initial values of the system parameters and the current values as changed by the SET SYSTEM command:

      • Default user ID for command security checks (CMDUSER).
      • Time in seconds for which queue manager exits can execute during each invocation (EXITLIM).
      • How many started server tasks to use to run queue manager exits (EXITTCB).
      • Number of log records written by IBM MQ between the start of one checkpoint and the next (LOGLOAD).
      • The Measured Usage Pricing property for this queue manager (MULCCAPT). This property is only displayed if the MULCCAPT property is set to REFINED.
      • The Operation Mode for this system (OPMODE). This is a list of three elements:

        • The first indicates whether the queue manager is operating in compatibility mode or new function mode.
        • The second shows the current compatibility level.
        • The third shows the level of new functions that are available.
      • The OTMA connection parameters (OTMACON).
      • Whether queue manager restart waits until all indexes are built, or completes before all indexes are built (QINDXBLD).
      • Coded character set identifier for the queue manager (QMCCSID).
      • The queue sharing group parameters (QSGDATA).
      • The RESLEVEL auditing parameter (RESAUDIT).
      • The message routing code assigned to messages not solicited from a specific console (ROUTCDE).
      • Whether SMF accounting data is collected when IBM MQ is started (SMFACCT).
      • Whether SMF statistics are collected when IBM MQ is started (SMFSTAT).
      • Default time, in minutes, between each gathering of statistics (STATIME).
      • Whether tracing is started automatically (TRACSTR).
      • Size of trace table, in 4 KB blocks, to be used by the global trace facility (TRACTBL).
      • Time between scanning the queue index for WLM-managed queues (WLMTIME).
      • WLMTIMU indicates whether WLMTIME is given in seconds or minutes.
      • Whether batch jobs can currently be swapped out during some MQ API calls or not (CONNSWAP). Attention: From IBM MQ Version 9.0, this keyword has no effect.
      • A list of messages excluded from being written to any log (EXCLMSG).
      • It might also return a report about system status.
    2. This command is issued internally by IBM MQ at the end of queue manager startup.
    3. Message CSQY101I includes the system parameter value for OPMODE that is being used in CSQ6SYSP. For more details, see Use CSQ6SYSP.

      In contrast, the OPMODE returned by the DISPLAY SYSTEM command has two further parameters containing the current compatibility and available function levels:

      • The compatibility level indicates which version the queue manager has been migrated from and therefore can fall back to if necessary providing the appropriate backward migration PTFs have been installed at that release.
      • The available function level indicates the available level of MQ new functions that are restricted by OPMODE. See OPMODE restrictions by version for more information on the functions that are restricted by OPMODE.

      This parameter is valid only on z/OS.


    Parameter descriptions for DISPLAY SYSTEM

      CMDSCOPE
      This parameter specifies how the command runs when the queue manager is a member of a queue sharing group. CMDSCOPE cannot be used for commands issued from the first initialization input data set CSQINP1.

        ' '
        The command runs on the queue manager on which it was entered. This is the default value.

        qmgr-name
        The command runs on the queue manager you specify, providing the queue manager is active within the queue sharing group.

        We can specify a queue manager name other than the queue manager on which the command was entered, only if you are using a queue sharing group environment and if the command server is enabled.

        *
        The command runs on the local queue manager and is also passed to every active queue manager in the queue sharing group. The effect is the same as entering the command on every queue manager in the queue sharing group.
