Store-and-Forward (SAF) destinations are used for asynchronous and disconnected peer communications. A message delivered to a SAF queue or a SAF topic will be forwarded to a queue or a topic in a remote cluster or server. Aspects of a SAF queues and topics behavior can be configured with a SAF queue or topic bean.
Fully Qualified Interface Name | If you use the getMBeanInfo operation in MBeanTypeServiceMBean, supply the following value as this MBean's fully qualified interface name:weblogic.j2ee.descriptor.wl.SAFDestinationBean

Factory Methods | No factory methods. Instances of this MBean are created automatically. | ||
Subtypes |
The following MBeans extend or implement this MBean type:
|
This section describes attributes that provide access to other MBeans. For more information about the MBean hierarchy, refer to WebLogic Server MBean Data Model.

These parameters control how the SAF destination performs message logging.
They allow the adminstrator to configure the SAF destination to change message logging when message life cycle changes are detected.
Factory Methods | No explicit creator method. The child shares the lifecycle of its parent. |
Privileges | Read only |
Type | MessageLoggingParamsBean |
Relationship type: | Containment. |
Specifies the error handling configuration used by this SAF destination.
Any change to this parameter affects only incoming messages; stored messages are not affected.
Privileges | Read/Write |
Type | SAFErrorHandlingBean |
Relationship type: | Reference. |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
This section describes the following attributes:
The local JNDI name of the remote destination.
Privileges | Read/Write |
Type | java.lang.String |
The name of this entity, represented in XML as an attribute.
Many of the elements within the JMS module are named entities. All of the named entities encased by a type in the XML file must be unique. This is the identifier used to delineate a particular entity within the JMS module.
This attribute cannot be modified externally from the module (for example, with a deployment plan) because it may be used inside the module referentially.
Privileges | Read/Write |
Type | java.lang.String |
Specifies the quality-of-service for non-persistent messages.
Exactly-Once
indicates that messages will be
forwarded to the remote side once and only once except for any
occurrence of server crashes.
At-Least-Once
indicates that messages will be
forwarded to the remote side at least once. No message will be lost
except for any occurrence of server crashes. However, messages may
appear in the remote endpoint more than once.
At-Most-Once
indicates that messages will be
forwarded to the remote side atmost once. No message will appear in
the remote endpoint more than once. However, messages may get
lost.
Any change to this parameter affects only incoming messages; stored messages are not affected.
Privileges | Read/Write |
Type | java.lang.String |
Default Value | At-Least-Once |
Legal Values |

Optional information that you can include to describe this named JMS descriptor bean.
JMS module saves this note in the JMS descriptor file as XML
PCDATA. All left angle brackets (<) are converted to the XML
entity <
. Carriage returns/line feeds are
preserved.
If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.
Privileges | Read/Write |
Type | java.lang.String |
The remote JNDI name of the remote destination.
Privileges | Read/Write |
Type | java.lang.String |
Specifies the default Time-to-Live value (expiration time), in
milliseconds, for imported JMS messages. The expiration time set on
JMS messages will override this value unless the SAF Default
Time-to-Live Enabled
field is switched on, which then
overrides the expiration time in JMS messages on imported
destinations.
Any change to this value affects only incoming messages; stored messages are not affected.
Privileges | Read/Write |
Type | long |
Minimum value | -1 |
Specifies the type of routing used to find a SAF agent when using the message Unit-of-Order feature.
Hash
indicates that producers use the hash code of
a message Unit-of-Order to find a SAF agent.
PathService
indicates that producers use the Path
Service to find a SAF agent.
Privileges | Read/Write |
Type | java.lang.String |
Legal Values |
|
Controls whether the Time-to-Live (expiration time) value set on
imported JMS messages will be overridden by the value specified in
the SAF Default Time-to-Live
field.
Any change to this parameter affects only incoming messages; stored messages are not affected.
