Message listener service custom properties

Use this panel to view or change an optional set of name and value pairs for custom properties of the message listener service.

To view this administrative console page, click Servers-> application_server-> Message Listener Service-> (In content pane, under Additional Properties) Custom Properties

You can use the Custom properties page to define the following properties for use by the message listener service.

NON.ASF.RECEIVE.TIMEOUT
The timeout in milliseconds for synchronous message receives performed by message-driven bean listener sessions in the non-ASF mode of operation.

You should set this property to a non-zero value only if you want to enable the non-ASF mode of operation for all message-driven bean listeners on the application server.

The message listener service has two modes of operation, Application Server Facilities (ASF) and non-Application Server Facilities (non-ASF).

Data type Integer
Units Milliseconds
Default ASF mode (custom property not created)
Range 0 or greater milliseconds
0
non-ASF mode is disabled
1 or more
The timeout in milliseconds for non-ASF message-driven bean listener synchronous session receives
Recommended If a transaction timeout occurs, the message must recycle causing extra work. If you want to use the non-ASF mode, set this property to lower than the transaction timeout, but leave spare at least the maximum duration of your message-driven bean's onMessage() method. For example, if your message-driven bean's onMessage() method typically takes a maximum of 10 seconds, and the transaction timeout is set to 120 seconds, you might set the NON.ASF.RECEIVE.TIMEOUT property to no more than 110000 (110000 milliseconds, that is 110 seconds).
MQJMS.POOLING.TIMEOUT
The number of milliseconds after which a connection in the pool is destroyed if it has not been used.

An MQSimpleConnectionManager allocates connections on a most-recently-used basis, and destroys connections on a least-recently-used basis. By default, a connection is destroyed if it has not been used for five minutes.

Data type Integer
Units Milliseconds
Default 5 minutes
Range
MQJMS.POOLING.THRESHOLD
The maximum number of unused connections in the pool.

An MQSimpleConnectionManager allocates connections on a most-recently-used basis, and destroys connections on a least-recently-used basis. By default, a connection is destroyed if there are more than ten unused connections in the pool.

Data type Integer
Units Number of connections
Default 10
Range
MAX.RECOVERY.RETRIES
The maximum number of times that a listener port managed by this service tries to recover from a failure before giving up and stopping. When stopped the associated listener port is changed to the stop state. The interval between retry attempts is defined by the RECOVERY.RETRY.INTERVAL custom property.

A failure can be one of two things:

Data type Integer
Units Retry attempts
Default 5
Range 0 (no retries) through 2147483647
RECOVERY.RETRY.INTERVAL
The time in seconds between retry attempts by a listener port to recover from a failure. The maximum number of retry attempts is defined by the MAX.RECOVERY.RETRIES custom property.

A failure can be one of two things:

Data type Integer
Units Seconds
Default 60
Range 1 through 2147483647
