To Edit a Connector Connection Pool
- In the navigation tree, expand the Resources node.
- Expand the Connectors node.
- Under the Connectors node, select the Connector Connection Pools node.
The Connector Connection Pools page opens.
- On the Connector Connection Pools page, click the name of the connector connection
pool that you are editing.
The Edit Connector Connection Pool page opens.
- From the Resource Adapter drop-down list, select a different resource adapter.
- From the Connection Definition drop-down list, select the class name for the connection
definition.
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.
- In the Description field, type a description of the connector connection pool.
- In the Initial and Minimum Pool Size field, specify the minimum number of
connections in the connector connection pool.
The default value is 8.
- In the Maximum Pool Size field, specify the maximum number of connections in
the connector connection pool.
The default value is 32.
- In the Pool Resize Quantity field, specify the number of connections to be
removed when pool idle timeout expires.
The default value is 2.
- In the Idle Timeout field, specify the maximum time in seconds that a
connection can remain idle in the pool.
The default value is 300.
- In the Max Wait Time field, specify the amount of time the
application requesting a connection will wait before getting a connection timeout.
The default value is 60000.
- Select the Connection Validation Required checkbox to enable 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.
- Select the On Any Failure checkbox so the Enterprise Server will close all
connections in the pool and reestablish them if a single connection fails.
If you do not select the checkbox, individual connections will be reestablished only
when they are used.
- From the Transaction Support drop-down list, select the type of transaction support for
the connection pool.
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 following options are available in the drop-down list:
- NoTransaction: Indicates that the resource adapter does not support resource manager local or
JTA transactions and does not implement XAResource or LocalTransaction interfaces.
- LocalTransaction: Indicates that 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.
- XATransaction: Indicates that 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.
- (Optional) Click the Flush button to flush all connections from the pool.
- Click Save.
Tip - To return to the default settings, click the Load Defaults button, then click
Save.
