How do you use CICS ISSUE ABORT?

Use CICS ISSUE ABORT with RESP parameters to check response codes and handle any errors appropriately.

What are the different types of aborts?

Abort types include basic aborts (basic aborts, mapped aborts, unmapped aborts, custom aborts), advanced aborts (advanced aborts, secure aborts, encrypted aborts, compressed aborts), and specialized aborts (specialized aborts, high-performance aborts, low-latency aborts, high-throughput aborts).

When should you use CICS ISSUE ABORT?

Use CICS ISSUE ABORT when building applications that need to issue aborts, when implementing abort management, when issuing aborts, when building abort systems, or when implementing abort functionality.

CICS ISSUE ABORT - Issue Abort

CICS ISSUE ABORT issues an abort, enabling abort management and output processing in CICS environments. It provides efficient abort capabilities for CICS applications.

What is CICS ISSUE ABORT?

Abort Processing

1. Abort Preparation

Abort preparation includes:

Abort validation
Abort formatting
Abort encoding
Abort processing

2. Abort Transmission

Abort transmission includes:

Abort routing
Abort delivery
Transmission confirmation
Error handling

3. Output Management

Output management includes:

User management

Common Response Codes

Success Response Codes

NORMAL (0): Abort issued successfully
ABORT (4): Abort issued

Error Response Codes

INVREQ (16): Invalid request
NOTFND (20): Resource not found
LENGERR (22): Length error
ABORT (24): Abort error

Best Practices

1. Abort Preparation

Prepare abort appropriately
Validate abort content
Handle different abort types
Ensure abort integrity

2. Error Handling

Check all response codes
Handle abort failures
Implement retry logic
Log error conditions

3. Performance Optimization

Minimize abort operations
Use efficient abort formats

Imagine you're stopping something:

When you want to stop something, you say "stop" and the thing stops. If the thing stops, you can do something else. If the thing doesn't stop, you have to try again.

CICS ISSUE ABORT is like stopping something. The computer program says "stop" and the thing stops. If the thing stops, the program can do something else. If the thing doesn't stop, the program has to try again.

Just like you stop things, the computer program stops things!

Exercises

Exercise 1: Abort Issuance

Write a CICS ISSUE ABORT command to issue an abort.

EXEC CICS ISSUE ABORT
    RESP(WS-RESPONSE)
    RESP2(WS-RESPONSE2)
END-EXEC.

Exercise 2: Abort Processing

How would you implement comprehensive abort processing that handles different abort types and requirements?

Answer: Identify different abort types and appropriate handling, implement abort validation and encoding, handle different abort types and capabilities, implement proper error handling for abort failures, optimize abort operations for performance, and maintain abort integrity throughout the process.
