Objects and actions on z/OS

The operations and control panels offer you many different types of object and a number of actions that we can perform on them.

The actions are listed on the initial panel and enable you to manipulate the objects and display information about them. These objects include all the IBM MQ objects, together with some extra ones. The objects fall into the following categories.

Refer to Actions for a cross-reference table of the actions which can be taken with the IBM MQ objects.

    Queues, processes, authentication information objects, namelists, storage classes and CF structures

    These are the basic IBM MQ objects. There can be many of each type. They can be listed, listed with filter, defined, and deleted, and have attributes that can be displayed and altered, using the LIST or DISPLAY, LIST with FILTER, DEFINE LIKE, MANAGE, and ALTER actions. (Objects are deleted using the MANAGE action.)

    This category consists of the following objects:

    QLOCAL Local queue
    QREMOTE Remote queue
    QALIAS Alias queue for indirect reference to a queue
    QMODEL Model queue for defining queues dynamically
    QUEUE Any type of queue
    QSTATUS Status of a local queue
    PROCESS Information about an application to be started when a trigger event occurs
    AUTHINFO Authentication information: definitions required to perform Certificate Revocation List (CRL) checking using LDAP servers
    NAMELIST List of names, such as queues or clusters
    STGCLASS Storage class
    CFSTRUCT coupling facility (CF) structure
    CFSTATUS Status of a CF structure

    Channels

    Channels are used for distributed queuing. There can be many of each type, and they can be listed, listed with filter, defined, deleted, displayed, and altered. They also have other functions available using the START, STOP and PERFORM actions. PERFORM provides reset, ping, and resolve channel functions.

    This category consists of the following objects:

    CHANNEL Any type of channel
    SENDER Sender channel
    SERVER Server channel
    RECEIVER Receiver channel
    REQUESTER Requester channel
    CLUSRCVR Cluster-receiver channel
    CLUSSDR Cluster-sender channel
    SVRCONN Server-connection channel
    CLNTCONN Client-connection channel
    CHSTATUS Status of a channel connection

    Cluster objects

    Cluster objects are created automatically for queues and channels that belong to a cluster. The base queue and channel definitions can be on another queue manager. There can be many of each type, and names can be duplicated. They can be listed, listed with filter, and displayed. PERFORM, START, and STOP are also available through the LIST actions.

    This category consists of the following objects:

    CLUSQ Cluster queue, created for a queue that belongs to a cluster
    CLUSCHL Cluster channel, created for a channel that belongs to a cluster
    CLUSQMGR Cluster queue manager, the same as a cluster channel but identified by its queue manager name

    Cluster channels and cluster queue managers do have the PERFORM, START and STOP actions, but only indirectly through the DISPLAY action.

    Queue manager and security

    Queue manager and security objects have a single instance. They can be listed, and have attributes that can be displayed and altered (using the LIST or DISPLAY, and ALTER actions), and have other functions available using the PERFORM action.

    This category consists of the following objects:

    MANAGER Queue manager: the PERFORM action provides suspend and resume cluster functions
    SECURITY Security functions: the PERFORM action provides refresh and reverify functions

    Connection

    Connections can be listed, listed with filter and displayed.

    This category consists only of the connection object, CONNECT.

    System
    A collection of other functions. This category consists of the following objects:

    SYSTEM System functions
    CONTROL Synonym for SYSTEM
    The functions available are:

    LIST or DISPLAY Display queue sharing group, distributed queuing, page set, or data set usage information.
    PERFORM Refresh or reset clustering
    START Start the channel initiator or listeners
    STOP Stop the channel initiator or listeners
