clip_image002WebLogic Server (WLS) 12.2.1 introduces a new datasource type that uses the Oracle Universal Connection Pool (UCP) as an alternative connection pool.  The UCP datasource allows for configuration, deployment, and monitoring of the UCP connection pool as part of the WLS domain.  It is certified with the Oracle Thin driver (simple, XA, and replay drivers).

The product documentation .  The goal of this article  is not to reproduce that information but to summarize the feature and provide some additional information and screen shots for configuring the datasource.
A UCP data source is defined using a jdbc-data-source descriptor as a system resource.  With respect to multi-tenancy, these system resources can be defined at the domain, partition, resource group template, or resource group level. 

The configuration  for a UCP data source is pretty simple with the standard datasource parameters.  You can  name it, give it a URL, user, password and JNDI name.  Most of the detailed configuration and tuning comes in the form of UCP connection properties.  The administrator can configure values for any setters supported by oracle.ucp.jdbc.PoolDataSourceImpl except LogWriter  (see oracle.ucp.PoolDaaSourceImpl) by just removing the "set" from the attribute name (the names are case insensitive).  For example, Read the complete article here.
