Clustering: Planning how to configure cluster transmission queues
You are guided through the choices of cluster transmission queues. You can configure one common default queue, separate default queues, or manually defined queues. Configuring multiple cluster transmission queues applies to platforms other than z/OS®.
Before you begin
Review How to choose what type of cluster transmission queue to use.
About this task
You have some choices to make when you are planning how to configure a queue manager to select a cluster transmission queue.
- What is the default cluster transmission queue for cluster message
transfers?
- A common cluster transmission queue,
SYSTEM.CLUSTER.TRANSMIT.QUEUE
. - Separate cluster transmission queues. The queue manager manages
the separate cluster transmission queues. It creates them as permanent-dynamic
queues from the model queue,
SYSTEM.CLUSTER.TRANSMIT.MODEL.QUEUE
. It creates one cluster transmission queue for each cluster-sender channel it uses.
- A common cluster transmission queue,
- For the cluster transmission queues that you do decide to create
manually, you have a further two choices:
- Define a separate transmission queue for each cluster-sender channel that you decide to configure manually. In this case, set the CLCHNAME queue attribute of the transmission queue to the name of a cluster-sender channel. Select the cluster-sender channel that is to transfer messages from this transmission queue.
- Combine message traffic for a group of cluster-sender channels
onto the same cluster transmission queue; see Figure 1.
In this case, set the CLCHNAME queue attribute
of each common transmission queue to a generic cluster-sender channel
name. A generic cluster-sender channel name is a filter to group cluster-sender
channel names. For example,
SALES.*
groups all cluster-sender channels that have names beginning withSALES.
. You can place multiple wildcard characters anywhere in the filter-string. The wildcard character is an asterisk,
. It represents from zero to any number of characters.*
