Optimizing the ADF Business Components Application Module Pool for Web Services

You can optimize the ADF Business Components application module pool for web services by changing some Business Component properties.

To change the configuration properties:

In the navigator, right-click the application module, and choose Configurations to display the Configurations Manager dialog.
Choose an existing configuration and click E dit, or create a new configuration by clicking Ne w. For more information about editing and creating configurations, press F1 or click Help from within the dialog.
To use your configuration property settings at runtime, make sure that the name of the configuration passed to the Configuration.createRootApplicationModule() method is the same as the name of the configuration where you set the properties.
In the Oracle Business Component Configurations dialog, click the Properties tab.
You can change one or both of the following properties:

jbo.ampool.dynamicjdbccredentials = false
The default is true, which allows each user to dynamically provide new username/password credentials for each use of the application module.
If you know that your application module will always use the same username, you can optimize the use of the application module by setting this property to false.

jbo.ampool.resetnontransactionalstate = false
This setting controls whether non-transactional resources like cached JDBC prepared statements are thrown away when the application module is checked back into the pool. The default is true because sharing the non-transactional application module state (VO where clauses, view criteria, and so on) should be done consciously.
By setting this property to false, prepared statements can be shared across uses of the pooled application module avoiding the JDBC overhead of recreating and reparsing them.
