Answer / deepika

transaction is an entity that initiates the execution of
task. The transaction identifier identifies the transaction
in CICS.
CEMT:
This is Master Terminal transaction. It is menu driven and
easy-to-use transaction but due to its nature of
manipulating the CICS environment, most of the functions
are restricted to application programmer or end user.
CEMT INQUIRE|SET|PERFORM
CEMT INQ TRAN|PRO|FILE – Display information from
PCT|PPT|FCT
CEMT INW TASK – Display the active running tasks
in the region
CEMT SET command can be used to reset the values of
PCT|PPT|FCT.
PERFORM has to be handled carefully. CEMT PERFORM SHUTDOWN
will shut down the entire CICS region.
Frequently used commands:
CEMT SET PR(PGM-NAME) NEW - To create a new copy of an
application program
CEMT SET DA(file-name) CLO/OPEN - To close/open a
file from CICS.
