Abstract

The invention relates to the retrieval of data records from a computer system. A user may retrieve selected error data records by specifying criteria and activating an error services utility. Only the error record data which satisfies the specified criteria will be printed or displayed. The user may also retrieve selected message data records by specifying criteria and activating an message services utility. The user may specify the display of selected messages which were generated by a specified component within the computer system. Moreover, after displaying a selected message, the user may request the system to display more detailed information regarding the displayed message.

Claims

1. In a multitasking computer system, a method of generating and retrieving error log records in said computer system, said method comprises the steps of:

operating a determination program to detect errors in the execution of a first task activated by a user of the multitasking computer system while the user interacts with a second task;

storing detected first task errors as records accessible by parameter reference through error log services;

enabling through a peripheral of said computer system an error log service;

entering a set of service type and time parameters into said system, which parameters can be associated with a record stored therein;

having said computer system retrieve a record which matches selected entered parameters; and

displaying to said user by operation of a selected utility program in said computer system said retrieved records in a predetermined format, specific criteria within said entered set of parameters and any data associated with said retrieved record.

2. The method as recited in claim 1 wherein said selected utility program is a print generation utility program and performs within said computer system the steps of:

accessing a record retrieved by the error log services;

comparing to selectively match said record to selected parameters; and

printing a record if said record matches selected parameters.

3. The method as recited in claim 1 wherein said selected utility program is a video display utility program and performs within said system the steps of:

accessing a record retrieved by the error log services;

comparing said record to said entered parameters;

displaying said retrieved record if said retrieved record matches all of said entered parameters; and

displaying said list of records having a selected one of said parameters in common;

whereby said retrieved record is highlighted in relation to said list of records upon display.

4. In a multitasking computer system, a method of generating and retrieving task message records in said computer system, said method comprises the steps of:

operating a determination program to detect messages in the execution of a first task activated by a user of the multitasking computer system while the user interacts with a second task;

storing detected first task messages as records accessible by parameter reference through message services;

enabling through a peripheral of said computer system a message service;

entering a set of service type and time parameters into said system, which parameters can be associated with a record stored therein;

having said computer system retrieve a record which matches selected entered parameters; and

displaying to said user by operation of a selected utility program in said computer system said retrieved record in a predetermined format, specific criteria within said entered set of parameters and any data associated with said retrieved record.

5. The method as recited in claim 4 wherein said retrieved record is a first record and further includes the steps of:

retrieving another record from said computer system subsequent to the retrieval of said first record;

comparing said another record to said entered message service parameters;

displaying said another record if said another record matches said parameters; and

retrieving other records stored in said system until all records which match said parameters have been displayed.
