Configure JMS template thresholds and quotas

Before you begin


After you create a JMS template, you can define upper and lower message and byte threshold and quota values for queues and topics created from the template.

To configure thresholds and quotas for a JMS template:

  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 template resource that you want to configure:
  3. Select Configuration > Thresholds and Quotas.
  4. To define thresholds for this JMS template:
    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 a destination. 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 a destination. Events include message flow control and system log messages.

    For more information about these fields, see Configuration Options.

  5. To define quotas for this queue:
    1. In Maximum Message Size, specify the maximum size of a message that will be accepted from message producers on a destination. 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 a destination.
    3. In Topic Subscription Messages Limit, specify the maximum number of messages that can be stored in a topic subscription before its earliest messages are deleted to make room for new messages.

    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).
