CICS - FAQ - Mainframe CICS World. Introduction To CICS. Explain the differences between a. Transaction and a Task. Under CICS, a user can't directly invoke a. Instead, the user invokes a transaction, which in turn specifies the. When a user invokes a transaction, CICS locates the. Where Task is a unit of work which is scheduled by. CICS. The difference between transaction and task is that while several users. Describe the basic differences between. In a Batch processing system, transactions are. For example the. processing of the Orders collected for the whole day.
In an Online processing. Airplane Reservation system. In a batch system. On- line system. it is measured in micro- seconds and seconds. On an Online system, if there is. Allstate Insurance Co., uses CICS V4. What are the four major types of Online. Programs? The file. The Data Entry program. Describe the different considerations. Online programs (CICS). IBM promotes a user interface standard called CUA (common user. Explain the usage of DFHCOMMAREA in a CICS program. How do the COBOL program knows.![]() Access). CUA provides Entry model, Graphical model, and Intermediate model - . Performance is a critical consideration for online. Performance for online systems is measured in terms of response time. The most critical factors are the total. CICS system, the Disk I/O, the terminal. A batch program. typically has complete control of the files it uses, so there's no chance of. In an online system however many. ![]() On batch systems Security implementation is simple. However in an online. Logon procedure being used. Using of multi- level security to allow. Describe the most common way a task is. CICS. By entering the Transaction Identifier on the. Enter Key. When the Trans- id is entered on the CICS. PCT. Then. the location of the program is determined by CICS by reading the entries in. PPT. After the load module is located, it loads it onto the CICS main memory. CICS own use to execute the task. The other different ways are by a transaction. By RETURN. command, By START command (Time- driven Automatic Task Initiation), By a DCT. TDQ write (Data- driven ATI), and by using 3. Distinguish between Multitasking and. Multi- threading. ![]() Multi- tasking means that the OS allows more than. Multi- threading is the system. Programs are shared by several tasks, and for each. Briefly describe the function of each. CICS modules. It is the interface between the CICS application program and. Operating System's Tele- Communication Access Method VTAM, TCAM or BTAM). An application program that uses terminal control directly. ![]() To relieve the. programmer from building complicated strings of control characters to send data. BMS is used that acts as interface between. BMS lets you create a map that specifies the. File control acts an. Application program interface and the VSAM files. The. application program interface acts as the interface between the file control. When a File control receives a request, it passes on. VSAM File, which in turn would manage the data storage. This service manages. API acts as the interface between the application program and. CICS services. It provides the. Whenever a. record is written to a destination it is added to the end. A task reads the. It provides the. simplest method for storing data outside your CICS program's working storage. Data is stored on TSQ's. If the amount of storage is small it can be. This service lets you. It provides a method of starting a task. It can be used to specify a task to start at. Since most programs keep. Cics-cobol-edupgm - CICS COBOL data marshaling sample.

You can use it to suspend your task temporarily to prevent. CICS resources and also. TSQ's. It maintains the Trace. ![]() CICS operations performed within a task. JCT, and others are SNT. SRT(sys. Describe the differences between. Pseudo- Conversational and a conversational program. In a conversational mode, the program accomplishes. The system. that sits idle without allowing an other operation while waiting for the data. In a Pseudo- Conversational program, a program. When the user completes the. Pseudo- conversational. CICS resources such as control tables efficiently. Briefly describe the functions of each. PCT, PPT, FCT. CICS creates internal control tables mentioned. Resource definitions created by the system programmers. By using. special assembler macro instruction or by using the Resource definition online. RDO). RDO is even called as CEDA as it is the transaction used. RDO. RDO is used to define the resources needed such as program. BMS, Trans- id, file info.. PCT contains a list of valid Trans- id paired with the name of a. CICS will load when the transaction is initiated with that transaction. It identifies priority and security level (RSLC) of transaction. CICS uses this information to determine whether new copy of the. Disk or it exists on storage. It contains. information such as Location in memory, Library address of the disk and. FCT contains the name and type of each file and in addition. It lists. whether the existing records can be read sequentially or randomly, deleted or. Others control tables used are TCT to register terminals, DCT, TST. RCT, SIT, SRT and SNT. Describe the basic eight steps of a. CICS program development according to Doug Lowe. The minimum the specifications should include program overview. Others that are needed are include decision tables. Most standard COBOL. In a pseudo- conversational CICS program there is no. Instead CICS invokes your program whenever there is an. CICS program is to be designed to respond. Before. you can test a CICS program, you need to make sure that all of the CICS table. For most programs the. PPT, PCT and FCT tables. Incidentally many shops use mapset generator. Coding the CICS programs involves. COBOL code with special CICS commands to invoke CICS. By either using the. Foreground command level translator or a JCL, compile the CICS application. Under which the CICS commands are commented out and replaced by. Translation. step. In addition to translation the CICS commands the translator also inserts. CICS instructions. Now the Cobol Source is. Cobol program. Under Microfocus. Checker is used. Load. After the test runs fine. Ok create the necessary documentation for the program. CICS. Programming Concepts. Explain the COBOL code used in a CICS. There is no difference between the COBOL and CICS. Identification Division, in which Program- Id is mandatory. The Environment. division of the CICS- COBOL program needs to be empty, as the Environmental. CICS tables such as FCT. Beginning with VS. COBOL II Release. In the Data. Division, File Section is not to be defined. It contains the working storage. Section and Linkage Section for all the programs. A field called COMMAREA is. Working- Storage Section and DFHCOMMAREA in Linkage section for all. Compiler adds Execute Interface Block (DFHEIB) in Linkage. The Procedure division is used to code the Program logic, to perform. Explain the COBOL code used to detect. How do you. pass information from one task to other? How do you test the response codes? Evaluate EIBCALEN variable to determine the first. If it's value is. The communication. The next field defined after. Response field, a. S9(8) comp). This field is used to test the completion. CICS (READ) command with the option RESP(Response field). What COBOL feature's are not allowed. CICS programs? ACCEPT, DISPLAY, OPEN, CLOSE, READ, WRITE. REWRITE, DELETE, START, SORT, RELEASE, RETURN, EXHIBIT, TRACE, Segmentation. Report writer features. The CICS using COBOL II features that are. OS/VS COBOL environment are GOBACK, STOP RUN, EXAMINE. STRING, UNSTRING and INSPECT. Explain the purpose of each of the CICS. CESN, CESF, CEMT, CECI and CEDF. CESN. - CICS Execution Sign On. CESNUSER=N6. SSAGI,PW=SUNIL1. It's. used for logging into the CICS System. CESF LOGOFF . It's used for Signing off. CEMTSET PROGRAM=(pgmname),NEWCOPY. It's used for variety of supervisory CICS functions. CEMT transaction can be. CEMTSET. DATASET(dataset) . CEMT SPR/TRANSACTION(name) . Ex. 1 tells CICS. You should issue this command whenever you recompile a. CICS is running. Otherwise CICS will continue to use the older. Are very useful when a. The only. catch is you might have to run the CEMT command from another terminal as this. You invoke this. transaction by typing the trans- id, optionally followed by the CICS command. When you press Enter, CECI executes the command. CECI can be used to update the contents of the files. To the right of each variable name is the. The various keys used under CECI transaction are F1- HELP. F2- HEX, F3- END, F4- EIB, F5- VAR, F6- User, F9- Message. It invokes a debugging aid. EDF. When EDF is activated, you can run a program step by step, checking. CICS command and examine the content of WS as needed. Define Event- Driven Design that is. CICS to follow pseudo- conversational approach. The. various steps include Identifying the user input events and then Designing the. Structure charts with. Basic Mapping Support. What is the importance of MDT in maps? An MDT on, which is a part of the attribute byte. Do not overlay the. BMS map's attributes with the symbolic map attributes on a SEND of map and. Symbolic map's attributes equal to low values will not overlay the BMS. Moving a standard attribute, which contains FSET to. Symbolic map's attribute before issuing the SEND which includes the. MOVE UNPROT- FSET TO MAPFLDA. Keying data into Unprotected field on the screen. Describe how to code a Mapset with a. BMS Macro instructions. The above Macro defines a constant field, an. ATTRB=UNPROT, An Alphanumeric Display only. User message area. A numeric data entry field QTY should have ATTRB=NUM. ATTRB=(NORM,PROT) with. PICOUT='zz,zzz,zz. Explain the function of Modified Data. List the Extended attributes with stress on highlighting. Last bit of the attribute byte indicates MDT. If. the user keys in any data into the field, it turns the MDT ON indicating that. To save transmission time , 3. TC line only if the MDT is on. Otherwise, the field value is not. The extended attributes of a field include extended Color (Red. Blinking. Reverse Video, Underline), Validation (Must fill, Must enter, Trigger), and.
