Pool Size Settings
The following settings control the size of the connection pool:
- Initial and Mimimum Pool Size
-
Size of the pool when created, and its minimum allowable size.
- Maximum Pool Size
-
Upper limit of size of the pool.
- Pool Resize Quantity
-
Number of connections to be removed when the idle timeout expires. Connections that have idled for longer than the timeout are candidates for removal. When the pool size reaches the initial and minimum pool size, removal of connections stops.
The following table summarizes pros and cons to consider when sizing connection pools.
