Question
Command to bring down CICS region immediately is
A. F CICS,cemt p Shut
B. F CICS,cemt I shut
C. F CICS,Cemt p shut I
D. C CICS
Answer
The command to bring down a CICS region immediately is:
C. F CICS,Cemt p shut I
Explanation
To break this down:
- ‘F CICS’ is used to direct a command to the CICS region
- ‘Cemt’ invokes the CICS master terminal transaction
- ‘p shut’ is the command to shut down CICS
- The ‘I’ (immediate) option after ‘p shut’ specifies to shut down CICS immediately
So the full command ‘F CICS,Cemt p shut I’ will force an immediate shutdown of the CICS region, without allowing currently executing tasks to finish. This should only be used if an emergency shutdown is required, as it can lead to incomplete transactions and data integrity issues. For a more graceful shutdown, omit the ‘I’ option.
The other options are incorrect because:
- ‘p Shut’ is missing the ‘I’ for immediate shutdown
- ‘I shut’ is the incorrect syntax
- ‘C CICS’ is used to cancel/force a CICS region, not shut it down
In summary, to immediately bring down a CICS region, use the command ‘F CICS,Cemt p shut I’ carefully and only when truly necessary. For normal CICS shutdowns, use ‘F CICS,Cemt p shut’ to allow a more orderly shutdown process.
