Abstract

A data processing system operates under the control of a control program having one or more versions. System dump data is generated on occurrence of an error condition. A dump analysis routine for analyzing dump data indicative of the error state of the system receives constant-format data from a version of a translation routine, the translation routine having one or more versions each corresponding to a version of the control program, and capable of translating the system dump data into the constant format required by the dump analysis routine.

Claims

1. A data processing system, operating under control of a control program having different versions, said data processing system comprising:

A) means for generating information indicative of a state of the data processing system;

B) an analysis means for analyzing said state of said data processing system; and

C) accessing means for accessing said information and providing said information to said analysis means in a constant format in response to an access request transmitted from said analysis means to said accessing means, said accessing means having different versions, each of said versions of said accessing means corresponding to a corresponding different one of said versions of the control program.

2. The data processing system of claim 1 further including a checker means for detecting an error condition in said system that causes termination of said control program, and in which said means for generating information is responsive to said checker means, and in which said state is coincident in time with said error condition.

3. The data processing system of claim 2 in which said analysis program means transmits said access request such that said request is format invariant among said different versions of said control.

4. The data processing system of claim 3 further comprising storage means organized as a plurality of storage areas for storing said information in response to said control program so that said information is indicative of the contents and logical interrelationships of those of said plurality of storage areas accessed by said control program.

5. The data processing system of claim 2 further comprising storage means organized as a plurality of storage areas for storing said information in response to said control program so that said information is indicative of the contents and logical interrelationships of those of said plurality of storage areas accessed by said control program.

6. The data processing system of claim 1 in which said analysis means transmits said access request such that said request is format invariant among said different versions of said control program.

7. The data processing system of claim 6 further comprising storage means organized as a plurality of storage areas for storing said information in response to said control program so that said information is indicative of the contents and logical interrelationships of those of said plurality of storage areas accessed by said control program.

8. The data processing system of claim 1 further comprising storage means organized as a plurality of storage areas for storing said information in response to said control program so that said information is indicative of the contents and logical interrelationships of those of said plurality of storage areas accessed by said control program.

9. A method for analyzing system dump data in a data processing system operating under control of an operational version of a control program having different versions, said method comprising the steps of:

A) generating information indicative of a state of the data processing system;

B) providing a version of an accessing means, in which said accessing means has different versions, said version provided by said accessing means corresponding to the operational version of the control program; and

C) having said version provided by said accessing means access said information and provide said information to a requesting analysis program in a constant format.

10. The method of claim 9 in which said step of generating information is responsive to an error condition causing termination of said operational version of said control program.
