How do you use CICS ISSUE ADD?

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

What are the different types of adds?

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

When should you use CICS ISSUE ADD?

Use CICS ISSUE ADD when building applications that need to issue adds, when implementing add management, when issuing adds, when building add systems, or when implementing add functionality.

CICS ISSUE ADD - Issue Add

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

Add Processing

1. Add Preparation

Add preparation includes:

Add validation
Add formatting
Add encoding
Add processing

2. Add Transmission

Add transmission includes:

Add routing
Add delivery
Transmission confirmation
Error handling

3. Output Management

Output management includes:

User management

Common Response Codes

Success Response Codes

NORMAL (0): Add issued successfully
ADD (4): Add issued

Error Response Codes

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

Best Practices

1. Add Preparation

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

2. Error Handling

Check all response codes

Manage user resources

Explain It Like I'm 5 Years Old

Imagine you're adding something:

When you want to add something, you say "add" and the thing gets added. If the thing gets added, you can do something else. If the thing doesn't get added, you have to try again.

CICS ISSUE ADD is like adding something. The computer program says "add" and the thing gets added. If the thing gets added, the program can do something else. If the thing doesn't get added, the program has to try again.

Just like you add things, the computer program adds things!

Exercises

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

Exercise 2: Add Processing

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

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