What are the CICS commands available for program control?

Correct Answer: The following are the ways of initiating a CICS transaction 1 By entering Transaction Id 2 By Start command 3 By Return Trans Id (as in pseudo - conversation) 4 By Registering Tran ID in plt so that it will be automaticaly dusring CICS start 5 By ATI (Automatic task initiation) 6PF & PA keys as defined in PCT

Correct Answer: - NOHANDLE is an option that can be specified along with abnormal condition during program execution - When the exception occurs, no action is performed during execution of NOHANDLE command - The abnormal condition is ignored, even the EXEC CICS HANDLE condition exist - The abnormal condition is also ignored when EXEC CICS IGNORE condition is tested - The previous HANDLE CONDITION for other commands will not be effected with NOHANDLE option

Correct Answer: READNEXT reads the next record from a browse operation for any of the three VSAM files

Correct Answer: Customer Information Control System (CICS) is an online transaction processing monitor from IBM that acts as an interface between the operating system and application programs to provide rapid high-volume online transaction processing

Correct Answer: DB2 acts as the participant and CICS acts as a co-ordinator

Correct Answer: The INTO option moves the information in the TIOA into the reserved specified area, while the SET option simply returns the address of the TIOA to the specified BLL cell or address of a linkage-section

Correct Answer: The CICS translator converts the EXEC CICS commands into call statements for a specific programming language There are CICS translators for Assembler, COBOL, and PL/1

Correct Answer: - Use a COBOL II CALL statement to invoke a subprogram This method is transparent to CICS, which sees only the one load module - EXEC LINK is similar to a call; it invokes a separate CICS program and ends with a RETURN to the invoking program - EXEC XCTL which transfers control to another CICS program and does not get control back COBOL II allows for static calls which are more efficient than the LINK instruction which establishes a new run-unit

Correct Answer: The enter and PF keys transmit data from the screen; the PA keys tell CICS that a terminal action took place, but data is not transmitted

Correct Answer: An abnormal situation during execution of a CICS command is called an exceptional condition: 1 Handle Condition Command: It is used to transfer control to the procedure label specified if the exceptional condition specified occurs 2 Ignore Condition Command: It causes no action to be taken if the condition specified occurs in the program That is control will be returned to the next instruction following the command which encountered the exceptional condition 3 No Handle Option: This option can be specified in any CICS command and it will cause no action to be taken for any exceptional condition occurring during execution of this command 4 RESP Option: This option can be specified in any CICS command If the RESP option is specified in a command, CICS places a response code at a completion of the command The application program can check this code, then proceed to the next processing
