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.
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
No factory methods. Instances of this MBean are created automatically.
You can access this MBean from the following MBean attributes:

The following MBeans extend or implement this MBean type:

This section describes attributes that contain child MBeans. For more information about the MBean hierarchy, refer to WebLogic Server MBean Data Model.

Specifies the error handling configuration used by this SAF destination.
Any change to this name affects only incoming messages; stored messages are not affected.
Factory Methods | No explicit creator method. The child shares the lifecycle of its parent. |

This section describes the following attributes:
The local JNDI name of the remote destination.
Any change to this name affects only incoming messages; stored messages are not affected.
Privileges | Read/Write |
Type | java.lang.String |
The name of this entity, represented in XML as a 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 |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
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 name affects only incoming messages; stored messages are not affected.

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.

Type | java.lang.String |
Specifies the default Time-To-Live value (expiration time), in
milliseconds, for JMS messages. The expiration time set on JMS
messages will override this value unless the Use SAF
Time-To-Live Default
option is enabled, which overrides the
expiration time in JMS messages on imported destinations.
Any change to this default affects only incoming messages; stored messages are not affected.

Type | long |
Minimum value | -1 |
Specifies the type of routing used find a dstributed destination member when using the Unit-of-Order.
Hash
indicates that producers use the hash code of
a Unit-of-Order to find a member.
PathService
indicates that producers use the Path
Service find a member.

Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Specifies whether the expiration time for JMS messages will be
overridden. If this value is enabled, the Time-To-Live
Default
value will override the setting on the imported
destination.
Any change to this default affects only incoming messages; stored messages are not affected.
