Configuration

General

Attribute
Description
Range of Values
Default

Name

Name of the destination. The JNDI name is configured separately.

This attribute is not dynamically configurable.

Java identifier, unique within the JMSServer

My JMS Destination[-n]

JNDI Name

Name used to look up the destination within the JNDI namespace. The destination name is configured separately. If not specified, the destination name is not advertised through the JNDI namespace.

This attribute is not dynamically configurable.

Java identifier, unique within the JNDI namespace scope

null

Enable Store

Flag specifying whether or not the destination uses the backing store specified by the JMS server.

If this flag is enabled, but no backing store is defined, then the configuration fails and WebLogic JMS does not boot. If this flag is disabled, then the destination does not support persistent messages. If this flag is set to Default, then the destination uses the backing store if one is defined.

This attribute is not dynamically configurable.

true, false, default

default

Template

Template from which the destination is derived. If this attribute is not defined, then the attributes for the destination must be specified as part of the destination.

The Template attribute setting per destination is static. The template attributes, however, can be modified dynamically.

Existing template name or none

none

Attribute
Description
Range of Values
Default

Bytes Maximum

Maximum number of bytes that may be stored in the destination. A value of -1 specifies that there is no limit on the number of bytes that can be stored in the destination.
