Uniform distributed queues - configure thresholds and quota

Before you begin


After you create a uniform distributed queue, you can change the default upper and lower byte and/or message thresholds for the distributed queue members. Exceeding these thresholds will which trigger events such as generating log messages and starting message flow control. You can also select a pre-configured quota, which specifies the maximum number of bytes or messages that the distributed queue is allowed to store to conserver memory use. You can also specify a maximum size allowed for messages on the distributed queue.

To configure thresholds and quota for a distributed queue:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the Administration Console, navigate to the uniform distributed queue resource that you want to configure:
  3. Click the Configuration > Thresholds and Quotas tab.
  4. To define thresholds for this distributed queue:
    1. In Bytes Threshold High or Messages Threshold High, specify an upper threshold value that will trigger events based on the number of bytes or messages stored in the members of this distributed queue. Events include message flow control and system log messages.
    2. In Bytes Threshold Low or Messages Threshold Low, specify a lower threshold value that will trigger events based on the number of bytes or messages stored in the members of this distributed queue. Events include message flow control and system log messages.

    For more information about these fields, see Configuration Options.

  5. To define quota for this distributed queue:
    1. In Maximum Message Size, specify the maximum size of a message that will be accepted from message producers on the members of this distributed queue. The size includes the message body, any user-defined properties, and the user-defined JMS header fields, JMSCorrelationID and JMSType.
    2. In Quota, select a configured quota settings for the members of this distributed queue.

    For more information about these fields, see Configuration Options.

  6. Save your changes:
  7. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
