These are part of the CICS-DB2 Interface. Dedicated threads are connections to DB2 that are always available to a particular application so that app doesn't have to wait. High priority apps use dedicated threads.

Pool threads are shared by all applications needing a connection (thread) to db2. It takes longer to allocate a pool thread to a waiting program. Normal, low priority apps use pool threads.

Remember: dedicated threads are dedicated to a particular application. This information is in a table called the Resource Control Table. It's not a CICS table and it's not a DB2 table.

The RCT is owned by the CICS-DB2 interface.  It's through this table that a cics transaction id is associated with a db2 plan and the characteristics of the thread (protected, pool, etc) are specified.
