org.apache.tomcat.jdbc.pool.interceptor.AbstractQueryReport
org.apache.tomcat.jdbc.pool.interceptor.ResetAbandonedTimer
- All Implemented Interfaces:
InvocationHandler,ResetAbandonedTimerMBean
Class that resets the abandoned timer on any activity on the
Connection or any successful query executions.
This interceptor is useful for when you have a
PoolConfiguration.setRemoveAbandonedTimeout(int)
that is fairly low, and you want to reset the abandoned time each time any operation on the connection is performed
This is useful for batch processing programs that use connections for extensive amount of times.-
