Threads are an important DB2 resource. A thread is a DB2 structure that describes
a connection made by an application and traces its progress.
When you install DB2, you choose a maximum number of active allied and
database access threads that can be allocated concurrently. Choosing a good
number for maximum threads is important to keep applications from queuing and
to provide good response time.
When writing an application, you should know when threads are created and
terminated and when they can be reused, because thread allocation can be a
significant part of the cost in a short transaction.
