Constructor Detail

SessionPoolStats

public SessionPoolStats(int minSize,
                        int maxSize,
                        int idleCount,
                        int acquiredCount,
                        int pendingAcquireCount)

Method Detail

getMinSize

public int getMinSize()

Returns:

Min number of sessions that should remain in session pool after idle session cleanup. This cleanup removes idle sessions that have idle time more than maxIdleTimeMillis. Session pool does not create sessions at startup, so IdleCount can be less than MinSize

getMaxSize

public int getMaxSize()

Returns:

Max number of sessions in pool. If session pool is full and timeout for acquire is set, acquire task will be put in a queue. If session pool is full and timeout is not set, "too many acquired objects" error will be received.

getIdleCount

public int getIdleCount()

Returns:

Number of sessions that were released after use and waiting to be acquired again or to be removed from pool by idle timeout.

getAcquiredCount

public int getAcquiredCount()

Returns:

Number of sessions currently acquired from pool and not yet released.

getPendingAcquireCount

public int getPendingAcquireCount()

Returns:

Number of sessions pending acquire due to pool overflow.
