Explain the basic difference between Intra partition TDQ and Extra partition TDQ.

INTRA PARTITION TD QUEUEs. It is a goup of sequential records which are produced by the same and / or different transaction within a CICS region. These Qs are stored in only one physical file (VSAM) in a CICS region, which is prepared by the system programmer. Once a record is read from a queuue, the record will be logically removed from the queue; that is the record cannot be read again EXTRA PARTITION TD QUEUEs It is a group of sequential record which interface between the transaction s of the CICS region and the systems outside of CICS region. Each of there TDQs is a separate physical file, and it may be on the disk, tap, printer or plotter.
