Use this page to define the general configuration for this JDBC multi data source. A JDBC multi data source is an abstraction around a group of data sources that provides load balancing and failover between data sources.
Multi data sources are bound to the JNDI tree. Applications can look up a multi data source on the JNDI tree and then reserve a database connection from a data source. The multi data source manages the connection request and provides a connection from one of its data sources.
Name | Description |
---|---|
Name |
A unique name that identifies this multi data source in the WebLogic domain. MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
JNDI Name |
The JNDI path to where this multi data source is bound. To specify multiple JNDI names for the multi data source, enter each JNDI name on a separate line. Applications that look up the JNDI path will get a
MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
Algorithm Type |
The algorithm determines the connection request processing for the multi data source. You can specify one of the following algorithm types:
MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
Failover Request if Busy |
For multi data sources with the MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
Failover Callback Handler |
The name of the application class to handle the callback sent when a multi data source is ready to failover or fail back connection requests to another data source within the multi data source. The name must be the absolute name of an application class that
implements the
