mqsicreatebroker command

Use the mqsicreatebroker command to create a broker and its associated resources.

Supported platforms

Windows
Linux and UNIX systems
z/OS®. Run this command by customizing and submitting BIPCRBK; see Contents of the broker PDSE

Purpose

The mqsicreatebroker command completes the following tasks.

The command checks whether the specified WebSphere® MQ queue manager exists:
- If the queue manager does not exist, the following behavior occurs.
  - If you run this command on z/OS, the action fails and an error is issued.
  - If you run this command on Linux, UNIX, or Windows, a queue manager is created.
    If WebSphere MQ Version 7.1, or later, has been selected for the queue manager, the channel auth security is automatically disabled.
    
    The queues that are created include a dead letter queue (DLQ), SYSTEM.DEAD.LETTER.QUEUE. The security settings are the same as for other broker-specific WebSphere MQ queues.
    
    If a message received by a message flow cannot be processed, it is typically backed out onto the input queue. If it cannot be backed out, or the message flow is not configured to back out messages, or to complete alternative error processing, the broker puts the message to the DLQ.
    
    The mqsideletebroker command does not delete the default DLQ (unless the queue manager is deleted).
- If the queue manager does exist, check that the queue manager has a DLQ defined; the queue is not created by this command on an existing queue manager, but is required because the broker puts messages that cannot be processed to the DLQ.
  If you use WebSphere MQ clusters in your domain, define the queue manager before you run this command, and configure the queue manager in the cluster to benefit from reduced administration and increased availability.
  - If you run this command on Linux, UNIX, or Windows and the existing queue manager is WebSphere MQ Version 7.1, or later, it is assumed that the user has applied the appropriate security configuration to meet their requirements, and therefore channel auth security is not disabled.
The command starts the WebSphere MQ queue manager, if it is not already running, except on z/OS.
If the command creates the queue manager on Windows, the queue manager is not started as a service. If you log off, the queue manager stops. Therefore, you must either remain logged on, or change the startup status of the queue manager service. If you lock your workstation, the WebSphere MQ queue manager does not stop.
The command connects to the associated queue manager.
The command creates the WebSphere MQ queues that are required by the broker, if they do not exist.
If you enable administrative security, the queues required for this support are also created by this command.
On Windows only, the command installs a service under which the broker runs.
The command creates the broker in one of the available operation modes. If the full package is installed, the default mode is advanced. If the Developer Edition is installed, the default mode is developer. For more information, see Operation modes.
The command creates a record for the component in the registry.
On Windows systems, Linux, and UNIX systems, the command allows you to specify, when the broker is created, whether the broker can be started and stopped as a WebSphere MQ service.
When you create a broker, the web user interface starts automatically on port 4414. You can disable the web user interface or change the port on which it runs by using the mqsichangeproperties command. If administration security is not enabled, web users can access the web user interface as a default user with unrestricted access to data and broker resources.

Brokers can access only local queue managers, so you cannot create a broker on a queue manager that is on a remote system.

Usage notes

If you have migrated from Version 6.1, the following restrictions apply.

In previous versions of IBM® Integration Bus, parameters that you specified on this command were used by the broker to provide default authorization for database access: either the database user ID and password (if specified) or the service user ID and password. Because the Version 9.0 broker does not use a database for its own purposes, the database user ID and password parameters have been deprecated. The broker service ID and password parameters have also been deprecated, except on Windows.

If you migrate a broker from a previous release, the associated values are stored and used for default database access as though you had entered these values by using the mqsisetdbparms command.

When you create a Version 9.0 broker, you must use the mqsisetdbparms command to set up database access authorization.

When you create a multi-instance broker, the resources are stored on a shared file system. The user that issues the mqsicreatebroker command must have the correct permissions on the shared file system to create these resources.

For details of this command on the operating system that your enterprise uses, see the appropriate topic.

Authorization

For information about platform-specific authorizations, see the following topics:

If you have enabled broker administration security, you must also set up the authority detailed in Tasks and authorizations for administration security.

WebSphere MQ queues created

SYSTEM.BROKER.ADAPTER.FAILED
SYSTEM.BROKER.ADAPTER.INPROGRESS
SYSTEM.BROKER.ADAPTER.NEW
SYSTEM.BROKER.ADAPTER.PROCESSED
SYSTEM.BROKER.ADAPTER.UNKNOWN
SYSTEM.BROKER.ADMIN.QUEUE

Access authority is granted for the IBM Integration Bus group mqbrkrs to all these queues. If the DLQ is enabled, it also has the same authority.

Responses

If you run the mqsicreatebroker command and it fails, resolve the problem that caused the failure:

Check responses; see Responses to commands.
Check the error logs; see Local error logs.
Check the error messages in the error log; you can search for error messages in the information center.

When you run the same command again, you might receive a series of messages specifying items that cannot be created. Receiving these messages does not indicate a problem with the mqsicreatebroker command itself.
