Adapting connection pooling for UPIC

Generally for each resource type or for each connection factory in the file weblogic-ra.xml, you can specify how connection pooling is carried out.

Connection pooling is used in order to increase the performance. max-capacity defines how many connections can be active for a connection factory at any one time; the default value is 10. Oracle WebLogic Server rejects connection requests that go beyond the number defined here with a ResourceAllocationException.

Connections which are used frequently and by many clients should be defined with large values for max-capacity. For rarely used connections you need not define connection pooling at all. For the other pool parameters, see the schema description for the file weblogic-ra.xml.
A connection factory definition with sample settings is listed in Example 7:

Example 7 Connection pooling

<connection-instance>   
      <jndi-name>eis/my_EIS</jndi-name>
      <connection-properties>
          <pool-params>
             <initial-capacity>2</initial-capacity>
             <max-capacity>10</max-capacity>   
          </pool-params>
           ...
      </connection-properties>      
</connection-instance>

For the other pool parameters, see the schema description for the file weblogic-ra.xml.
