Objects and actions on z/OS®

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
