EXEC CICS SIGNOFF
    [RESP(response-code)]
    [RESP2(response-code-2)]
END-EXEC.

Parameters Explained

RESP Parameters

Response codes returned by the command:

  • RESP: Primary response code - indicates the success or failure of the signoff operation
  • RESP2: Secondary response code - provides additional error information when RESP indicates failure
  • Always check these codes for command success before proceeding with data processing
  • Handle command failures appropriately to prevent application errors

Signoff Types

1. Basic Signoffs

  • Basic signoffs: Standard signoff operations that handle simple signing off without special formatting
  • Mapped signoffs: Signoff operations that use predefined field mappings to structure signoff data
  • Unmapped signoffs: Raw signoff operations that handle unstructured signing off without predefined field mappings
  • Custom signoffs: Specialized signoff operations designed for specific application requirements

2. Advanced Signoffs

  • Advanced signoffs: Complex signoff operations that handle sophisticated signing off processing and validation
  • Secure signoffs: Signoff operations that include encryption and security features for sensitive signing off
  • Encrypted signoffs: Signoff operations that automatically encrypt signoff data
  • Compressed signoffs: Signoff operations that handle compressed signing off streams and automatically compress signoff data

3. Specialized Signoffs

  • Specialized signoffs: Signoff operations tailored for specific protocols or communication methods
  • High-performance signoffs: Optimized signoff operations designed for maximum throughput and efficiency
  • Low-latency signoffs: Signoff operations optimized for minimal delay and real-time processing requirements
  • High-throughput signoffs: Signoff operations designed to handle large volumes of signing off efficiently

Signoff Processing

1. Signoff Preparation

Signoff preparation includes:

  • Signoff validation - ensuring the signoff operation is properly configured and authorized
  • Signoff formatting - preparing data structures and buffers for signoff data
  • Signoff encoding - setting up proper character encoding and data transformation
  • Signoff processing - initializing the signoff operation and preparing for signing off

2. Signoff Transmission

Signoff transmission includes:

  • Signoff routing - directing signoff data to the appropriate processing location
  • Signoff delivery - ensuring signoff data reaches the correct destination within the application
  • Transmission confirmation - verifying that signoff was completed successfully
  • Error handling - managing transmission failures and implementing retry mechanisms

3. Output Management

Output management includes:

  • User management - handling user sessions and maintaining connection state
  • Output formatting - structuring signoff data for presentation or further processing
  • User experience - ensuring smooth data flow and responsive application behavior
  • Performance optimization - maximizing signoff efficiency and minimizing resource usage

Common Response Codes

Success Response Codes

  • NORMAL (0): Signoff operation completed successfully - signing off was completed without errors
  • SIGNOFF (4): Signoff operation completed - operation completed with signoff-specific status

Error Response Codes

  • INVREQ (16): Invalid request - the signoff operation parameters are incorrect or unauthorized
  • NOTFND (20): Resource not found - the specified signoff resource does not exist
  • LENGERR (22): Length error - the signoff data length exceeds expected limits
  • SIGNOFF (24): Signoff error - a signoff-specific error occurred during the operation

Best Practices

1. Signoff Preparation

  • Prepare signoff appropriately - ensure all necessary resources and configurations are in place
  • Validate signoff content - verify that signoff data meets expected format and quality standards
  • Handle different signoff types - implement flexible processing to accommodate various signing off formats
  • Ensure signoff integrity - maintain data consistency and prevent corruption during signing off

2. Error Handling

  • Check all response codes - always examine both RESP and RESP2 for complete error information
  • Handle signoff failures - implement appropriate recovery mechanisms for failed signoff operations
  • Implement retry logic - provide automatic retry capabilities for transient failures
  • Log error conditions - maintain detailed logs for troubleshooting and monitoring purposes

3. Performance Optimization

  • Minimize signoff operations - reduce unnecessary signoff calls to improve overall performance
  • Use efficient signoff formats - choose appropriate data formats to minimize processing overhead
  • Optimize user updates - streamline user interface updates to reduce response time
  • Manage user resources - efficiently allocate and manage system resources for signoff operations

Explain It Like I'm 5 Years Old

Imagine you're signing off:

When you want to sign off, you say goodbye and sign off. If you sign off, you leave. If you don't sign off, you stay.

CICS SIGNOFF is like signing off. The computer program says goodbye and signs off. If it signs off, it leaves. If it doesn't sign off, it stays.

Just like you sign off, the computer program signs off!

Exercises

Exercise 1: Signoff Operation

Write a CICS SIGNOFF command to perform a signoff operation.

Exercise 2: Signoff Processing

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

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