The physical MAPSET is a LOAD module used to map the data to the screen at EXECUTION time. The symbolic map is the actual copybook member used in the program to reference the input and output FIELDS on the screen.

There are TIMES when many USERS are concurrently using the same PROGRAM, this is what we call MultiThreading, For example, 50 users are using program A, CICS will provide 50 Working storage for that program but one Procedure Division. And this technique is known as quasi-reentrancy.

The first way is to CODE a physical map and then code a matching symbolic map in your COBOL program. The SECOND way to create a physical map along with a matching symbolic map is to code only the physical map using the and SYSPARM option, CICS will automatically create a member in a COPY library. And the THIRD way is to use a map generator such as SDF ( Screen Definition Facility ).

PCT contains a list of valid TRANSACTION ID. Each transaction ID is paired with the name of the program, CICS will load and execute when the transaction is invoked. On the other hand, PPT indicates each program's location which pertains to a storage ADDRESS if the program has ALREADY been loaded or a disk location if the program hasn't been loaded. PPT will also be used to detemine whether it will load a new COPY of the program when the transaction is invoked.

The XCTL command passes control to another program, but the resources requested by the first program may STILL be allocated. A task does not end until a RETURN statement is EXECUTED. While in LINK command, program control resumes its instruction following the LINK PARAMETER. The disadvantage of LINK is that it requires that both the CALLING program and the called program remain in main memory even though both are no longer needed.

We can initiate CICS transaction
a) by GIVING transaction id
b) by giving CICS START COMMAND
C) automatic TASK initiation.

The EIB is the EXECUTIVE INTERFACE BLOCK. It is not the EXECUTE INTERFACE BLOCK. All TP monitors or transaction processor are know as EXECUTIVES as they carry out PROCESS on BEHALF of a program module. CICS and DB2 are executives.

You have to EXPLICITLY SPECIFY the WORD CURSOR between your EXEC CICS and END-EXEC in the PROGRAM.

TDQ is read destructive, TSQ is not, TSQ can be created DYNAMICALLY, TDQ cannot be created dynamically. TSQ is temporary in nature (i.e. it will be deleted when the program finishes execution, UNLESS it is MADE permanent by making a ENTRY in the Temporary Storage Table), TDQ is not.

This occurs when a PROGRAMMER Issues a EXEC CICS Syncpoint command. this is CALLED two phase because CICS will FIRST commit CHANGES to the RESOURCES under its control like VSAM files, and the DB2 changes are committed. Usually CICS signal DB2 to complete the next phase and release all the locks.

It OCCURS when PROGRAM interruption takes place. e.g. when alphanumeric STRING moved to numeric DATA item OR when arithmetic calculations performed on nunnumeric data item OR when an ATTEMPT made to read an occurrence of a table beyond the defined occurrences.

There are six ways in initiating a transaction they are as FOLLOWS.
1. embedding four character transid on the top left most CORNER of the screen.
2. making use of EXEC CICS START TRANSID()
3. making use of EXEC CICS RETURN TRANSID()
4. By defining the transid in DCT ( destination control table ) to enable ATI ( AUTOMATIC TASK INITIATION)
5. Making use of PLT ( program list table )
6. By associating four character transid in PCT ( program control table )

U-for unconditional breakpoint, C-for conditional breakpoint, and A-for automatic breakpoint

1. Alink was issued to a program whose name does not exist in the PPT (Program Processing Table).
2. A program attempted to use a map that is not defined in the PCT ( Program Control Table).
3. A SECURITY VIOLATION has occurred. The operator is not defined with the proper authority in the SNT ( Sign on Table ) to use a particular file.
4.  A program interrupt (0C0 or 0C2 ot ...) has occurred in a CICS program.
5. An I/O error has occurred when attempting to use a VSAM file from a CICS program.

    

Communication Area is USED to PASS data between the PROGRAM or between the task.

Both are used to SAVE data among tasks. but
1. COMMAREA is private to that transaction only like every transaction has its own COMMAREA CREATED by CICS as soon as the transaction is INITIATED. however TSQ, if queue id is known can be accessed by other transactions also
2. COMMAREA length is s9(4) comp i.e. 65k. but TSQ can have any length
3. COMMAREA is available only during the transaction is running. TSQ if created with auxiliary OPTION resides in aux memory and available even if main memory crashes
4. normally COMMAREA is used to transfer data from one task to another while TSQ is used widely within the task as a scratch pad.

In CASE of call, WHENEVER you do CHANGES to the called PROGRAM you need to COMPILE the calling program also. In case of link, it is not needed.

JOURNAL Recovery is recovery of CHANGES made to a file during online processing. If a file has I/O problems it is restored from a backup taken before online processing BEGAN and the journalled changes are applied. Dynamic transaction backout is the removal of partial changes made by a FAILED transaction.

MASSINSERT is a WRITE OPTION that modifies normal VSAM split processing, leaving free space after the inserted record, so subsequent RECORDS can be inserted without SPLITS. it is ended by an UNLOCK COMMAND.
