System Error Messages

System error messages are sent by the SERRC system error macro and are accompanied by a dump and possibly a system shutdown. The TPFDF product issues these messages while running in an IBM Transaction Processing Facility (TPF) environment or an IBM Airline Control System (ALCS) environment.

Analyzing a System Error Message

Once you locate the system error message, you will notice that the system error number is framed in a box for quick access. Below each system error message you will find the following information to help you analyze the message.

Information
Description

 Program 
Indicates the name of the program that found the error when that program is not available to the TPFDF product for display on the console and in the dump.

 Error Message 
Provides the text of the system error message that is displayed on your screen and printed in the dump, if there is any. If there are supplementary messages appearing in the dump, you will find more than one error message for each system error message.

In the message text, variable information is shown in italicized lowercase letters. When a system error actually occurs, specific information is provided for the variable information in the message that is displayed on your screen or printed in the dump. Explanations of the variable information are described immediately following the message text.

Note:
If there is no error message text, the word None is printed.

 Explanation 
Provides a brief description of the error conditions and the reason why an error occurred. A description of any variable information that is included in the message text may also be included in this explanation.
Note:
If there is no explanation necessary, the word None is printed.

 System Action 
Indicates the action taken by the TPFDF product, TPF system, or ALCS environment as a result of the error and provides an explanation that indicates the results of the error.
Note:
If there is no system action taken, the word None is printed.

 User Response 
Provides suggestions for a user action to correct the problem. Bulleted lists and numbered lists may be used to present this information to you. A bulleted list is used to present several different actions you can perform to resolve the problem. These actions are ordered from the least severe to the most severe. A numbered list is used whenever you must follow a procedure in sequential order to resolve a problem.

Notes:

  1. If there is no user response necessary, the word None is printed.

  2. The user responses are suggestions. Verify any action with your system support personnel first.
