- Question
What happens when a CICS command contains the NOHANDLE option?
- 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 simplest DB2 index is the B-tree and the B-tree's top page is called the root page The root page entries represent the upper range limits of the index and are referenced first in a search
Correct Answer: A QUIESCE flushes all DB2 buffers on to the disk This gives a correct snapshot of the database and should be used before and after any IMAGECOPY to maintain consistency
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: The following commands are available for the Program Control services: LINK: To pass control to another program at the lower level, expecting to be returned XCTL: To pass control to another program at the same level, not expecting to be returned RETURN: To return to the next higher-level program or CICS LOAD: To load a program RELEASE: To release a program
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
