The minimum number of threads is the number of threads that are
started when the Network Server is booted. This value is specified as a
property, derby.drda.minThreads=min. The
maximum number of threads is the maximum number of threads that will be used for
connections. If more connections are active than there are threads available,
the extra connections must wait until the next thread becomes available. Threads
can become available after a specified time, which is checked only when a thread
has finished processing a communication.
