This tab defines threshold and quota attributes for an instance of a JMS server. A JMS server manages connections and message requests on behalf of clients. You must first configure a JMS server before you can configure any destinations or consumers.

Attribute Label	Description	Value Constraints
Bytes Maximum	The value of BytesMaximum. The maximum number of bytes that may be stored in the JMS server.

Bytes Threshold High	The value of BytesThresholdHigh. Upper threshold value that triggers events based on the number of bytes stored in the JMS server. If the number of bytes exceeds this threshold, the triggered events are: Log Messages - A message is logged on the server indicating a high threshold condition. Bytes Paging - If bytes paging is enabled (and a paging store has been configured), then server bytes paging is started.

Description

Bytes Maximum

The value of BytesMaximum.

The maximum number of bytes that may be stored in the JMS server. A value of -1 specifies that there is no limit on the number of bytes that can be stored in the JMS server.

Range of Values: >= BytesThresholdHigh

This attribute is dynamically configurable.

Default: -1

Configurable: yes

Dynamic: yes

Readable: yes

Writable: yes

Bytes Threshold High

The value of BytesThresholdHigh.

Upper threshold value that triggers events based on the number of bytes stored in the JMS server. If the number of bytes exceeds this threshold, the triggered events are:

Log Messages - A message is logged on the server indicating a high threshold condition.

Bytes Paging - If bytes paging is enabled (and a paging store has been configured), then server bytes paging is started.

Flow Control - If flow control is enabled, the JMS server becomes armed and instructs producers to begin decreasing their message flow.

A value of -1 specifies that server bytes paging, flow control, and threshold log messages are disabled for the JMS server.

Range of Values:<= BytesMaximum; >BytesThresholdLow

This attribute is dynamically configurable.

Note:Bytes paging cannot be dynamically disabled by resetting the BytesThresholdHigh to -1. To disable paging, you could set the BytesThresholdHigh to a very large number, so that paging would not be triggered.

Bytes Threshold Low

The value of BytesThresholdLow

Lower threshold value that triggers events based on the number of bytes stored in the JMS server. If the number of bytes falls below this threshold, the triggered events are:

Log Messages - A message is logged on the server indicating that the threshold condition has cleared.

Bytes Paging - If bytes paging is enabled, paging is stopped (if paging is occurring).

Flow Control - If flow control is enabled, the JMS server becomes disarmed and instructs producers to begin increasing their message flow.
