> # Domain Partition: Resource Groups: Services: Store-and-Forward (SAF) Agents

> Column Display Related Tasks Related Topics

> There are two sides involved in the process of storing and forwarding messages: a local sending side and a remote receiving endpoint. SAF agents are responsible for store-and-forwarding messages between these local sending and remote receiving endpoints. A SAF agent can be configured to have only sending capabilities, receiving capabilities, or both.

> This page summarizes the SAF agents that have been created for this resource group.

> NOTE: WebLogic Server Multitenant domain partitions, resource groups, resource group templates, and virtual targets are deprecated in WebLogic Server 12.2.1.4.0. The related Console and help pages will be removed in the next release.

> You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.

> The following table lists all of the data points that you can display in columns on this page.

> Name | Description
> --- | ---
> Name | The name of this Store-and-Forward agent. MBean Attribute: `WebLogicMBean.Name` Changes take effect after you redeploy the module or restart the server.
> Agent Type | The type of service that this SAF agent provides. JMS requires only a Sending agent on the sending side for messages. Whereas, Web Services Reliable Messaging requires both a Sending and Receiving agent for messages.
> - Sending-only

>   Configures an agent that stores messages in persistent storage, forwards messages to the receiving side, and re-transmits messages when acknowledgements do not come back in time.

> - Receiving-only

>   Configures an agent that detects and eliminates duplicate messages sent by a receiving agent, and delivers messages to the final destination.

> - Both

>   Configures an agent that has sending and receiving agent functionality.

> If the value is changed and activated, you need to restart any servers to which the MBean is targeted before the value will take effect (even though you do not get a warning in the Console that the server needs to be restarted).

> MBean Attribute:
> `SAFAgentMBean.ServiceType`

> Changes take effect after you redeploy the module or restart the server.

> Persistent Store | The persistent disk-based file store or JDBC-accessible database for the SAF agent. If a store is not configured, the server's default store is used. If the value is changed and activated, you need to restart any servers to which the MBean is targeted before the value will take effect (even though you do not get a warning in the Console that the server needs to be restarted).

> MBean Attribute:
> `SAFAgentMBean.Store`

> Changes take effect after you redeploy the module or restart the server.

> Scope | Specifies if the Store-and-Forward Agent is accessible within the domain, a partition, or a resource group template.
> Domain Partitions | List of domain partitions that this Store-and-Forward Agent is available.
