END-EXEC.

Parameters Explained

USERID Parameter

Specifies the user ID to sign on:

  • Must be a valid user ID
  • Identifies specific user
  • Required for all SIGNON TOKEN operations
  • Must be active user

TOKEN Parameter

Token Processing

1. Token Preparation

Token preparation includes:

  • Token validation
  • Token formatting
  • Token encoding
  • Token processing

2. Token Transmission

Token transmission includes:

  • Token routing
  • Token delivery
  • Transmission confirmation
  • Error handling

3. Output Management

Output management includes:

  • User management
  • Output formatting
  • User experience
  • Performance optimization

Common Response Codes

Success Response Codes

  • NORMAL (0): User signed on successfully
  • SIGNON (4): User signed on

Error Response Codes

  • INVREQ (16): Invalid request
  • NOTFND (20): User not found
  • LENGERR (22): Length error
  • SIGNON (24): Sign on error

Best Practices

1. Token Preparation

  • Prepare token appropriately
  • Validate token content
  • Handle different token types
  • Ensure token integrity

2. Error Handling

  • Check all response codes
  • Handle sign on failures
  • Implement retry logic
  • Log error conditions

3. Performance Optimization

  • Minimize token sign on
  • Use efficient token formats
  • Optimize user updates
  • Manage user resources

Explain It Like I'm 5 Years Old

Imagine you're going to a special party:

When you want to go to a special party, you need a special invitation card. You show the invitation card to the person at the door, and they let you into the party.

CICS SIGNON TOKEN is like going to a special party. The computer program needs a special token (like an invitation card) to let the user into the system. The user shows the token to the system, and the system lets them in.

Just like you need an invitation card to go to a special party, the user needs a token to go to the system!

Exercises

Exercise 1: Token Sign On

Write a CICS SIGNON TOKEN command to sign on a specific user with a token.

EXEC CICS SIGNON TOKEN
    USERID(WS-USER-ID)
    TOKEN(WS-TOKEN-VALUE)
    RESP(WS-RESPONSE)
    RESP2(WS-RESPONSE2)
END-EXEC.

Exercise 2: Token Processing

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

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