What types of process browse termination are available?

Termination types include normal termination (graceful, safe, ordered, validated), immediate termination (immediate, emergency, abrupt, override), process type termination (process type, multi-type, process-group, process-pattern), and batch termination (batch, group, category, pattern).

How do I handle errors with CICS ENDBROWSE PROCESS?

Always check the response code and implement appropriate error handling, including validation of browse operation existence, proper handling of termination errors, and resource cleanup on termination failures.

What is the purpose of process browse termination?

Process browse termination ends process browse operations, cleans up associated resources, frees memory and other resources, and maintains system efficiency by properly closing browse sessions.

When should I use CICS ENDBROWSE PROCESS?

Use this command when you need to terminate process browse operations, clean up resources, free system resources, or properly close browse sessions in CICS applications.

Best Practices

Process Browse Termination Best Practices

• Always check response codes
• Use appropriate termination parameters
• Implement proper error handling
• Ensure proper resource cleanup

• Optimize termination operations
• Clean up resources properly

Explain It Like I'm 5 Years Old

Think of CICS ENDBROWSE PROCESS like finishing looking through a list of workers:

• List Name: "Which list of workers you were looking through" - The request ID
• Close the List: "Put the list away" - End the browse
• Clean Up: "Put everything back where it belongs" - Resource cleanup
• All Done: "Finished looking through the worker list" - Browse terminated

Exercises

Exercise 1: Basic Process Browse Termination

Create a program that terminates a basic process browse operation.

Exercise 2: Multiple Process Browse Termination

Write a program that terminates multiple process browse operations.

Exercise 3: Error Handling

Implement comprehensive error handling for process browse termination failures and cleanup errors.
