Oracle10g implicit caching with jdbc - cache only grows?

Hi,

Does the implicit cache of Oracle's 10g drivers (using ojdbc14.jar) ever release unused connections? For example, we set the MinLimit property in the OracleDataSource to 15 and the MaxLimit to 40. Already opened connections get reused as expected, and when they're not enough new ones are opened. However, once the load on the application dies down, the number of connections never decreases back down to the MinLimit. If 40 connections are opened, all 40 remain until the application shuts down. Are we supposed to call the OracleConnectionCacheManager.purgeCache() method to free up unused connections at regular intervals? That doesn't seem right....

Thank you,
Yuriy
