# Weighted Distributed Topic: Configuration: General

Configuration Options Related Tasks Related Topics

Use this page to define the general configuration of a weighted distributed topic, whose members can carry extra message load or have extra capacity.

#### Configuration Options

Name | Description
--- | ---
Name | The name of this weighted distributed topic.
JNDI Name | The name used to bind a virtual destination to the JNDI tree. Applications can use the JNDI name to look up the virtual destination. If not specified, then the destination is not bound into the JNDI namespace. MBean Attribute (Does not apply to application modules): `DistributedDestinationBean.JNDIName`
Load Balancing Policy | Determines the load balancing policy for producers sending messages to a distributed destination in order to balance the message load across the members of the distributed set. Round-Robin - The system maintains an ordering of physical topic members within the set by distributing the messaging load across the topic members one at a time in the order that they are defined in the configuration file. Each WebLogic Server maintains an identical ordering, but may be at a different point within the ordering. If weights are assigned to any of the topic members in the set, then those members appear multiple times in the ordering. Random - The weight assigned to the topic members is used to compute a weighted distribution for the members of the set. The messaging load is distributed across the topic members by pseudo-randomly accessing the distribution. In the short run, the load will not be directly proportional to the weight. In the long run, the distribution will approach the limit of the distribution. A pure random distribution can be achieved by setting all the weights to the same value, which is typically set to 1. MBean Attribute (Does not apply to application modules): `DistributedDestinationBean.LoadBalancingPolicy`
SAF Export Policy | MBean Attribute (Does not apply to application modules): `DistributedDestinationBean.SafExportPolicy` Changes take effect after you redeploy the module or restart the server.
