Edit Connector Connection Pool
Use the Edit Connector Connection Pool page to modify the settings for a
connector connection pool.
The Edit Connector Connection Pool page contains the following options.
- JNDI Name
A unique name that identifies the connector connection pool. The JNDI name is a read-only field. You can only specify the JNDI name when you create a new connector connection pool.
- Resource Adapter
The resource adapter associated with the connector connection pool.
- Connection Definition
The connection definition for the connector connection pool. The choices in the list depend on the resource adapter you selected. The connection definition identifies a resource adapter's connection-definition element in thera.xml file.
- Description
A description of the connector connection pool.
- Initial and Minimum Pool Size
The minimum number of connections in the connector connection pool. The default value is 8.
- Maximum Pool Size
The maximum number of connections in the connector connection pool. The default value is 32.
- Pool Resize Quantity
The number of connections to be removed when pool idle timeout expires. The default value is 2.
- Idle Timeout
The maximum time in seconds that a connection can remain idle in the pool. The default value is 300.
- Max Wait Time
The amount of time the application requesting a connection will wait before getting a connection timeout. The default value is 60000.
- Connection Validation
If the Required checkbox is selected, connections are validated before being given to the application. If a resource's validation fails, it is destroyed, and a new resource is created and returned. This option is disabled by default.
- On Any Failure
If the Close All Connections checkbox is selected, the Enterprise Server will close all connections in the pool and reestablish them if a single connection fails. This option is disabled by default.
- Transaction Support
The chosen transaction support overrides the transaction support attribute in the resource adapter associated with this connection pool in a downward compatible way. In other words, it can support a lower transaction level than that specified in the resource adapter, or the same transaction level as that specified in resource adapter, but it cannot specify a higher level.
The value may be any of the following:
- XATransaction
The resource adapter supports resource manager local and JTA transactions by implementing the LocalTransaction and XAResource interfaces. XA transactions are controlled and coordinated by a transaction manager external to a resource manager.
- LocalTransaction
The resource adapter supports local transactions by implementing the LocalTransaction interface. Local transactions are managed internal to a resource manager and involve no external transaction managers.
- NoTransaction
The resource adapter does not support resource manager local or JTA transactions and does not implement the XAResource or LocalTransaction interfaces.
