US 2019/0095270 A1 · TAILORING DIAGNOSTIC INFORMATION IN A MULTITHREADED ENVIRONMENT

Abstract

Tailoring diagnostic information specific to current activity of multiple threads within a computer system. A request to dump system state is received. A system dump is created, including main memory and system state information. The system dump is stored to a database. In response to a request to format the system dump, the system dump is loaded from the database, whereby a virtual memory image of system state at system dump time is created. The virtual memory image and system state information is scanned to identify tasks that were running, tasks that have failed due to an error, and tasks that were suspended at system dump time. State information and control blocks associated with the identified tasks are collected from the system dump and collated based on task number. The database is updated with a formatted system dump, including the state information and control blocks associated with the identified tasks.

Dependent claims

A computer-implemented method for tailoring diagnostic information specific to current activity of multiple threads within a computer system, the method comprising:

creating, by one or more processors, a system dump, including main memory and system state information, the system dump being a first hardware memory mapping;
storing, by one or more processors, the system dump to a database;
executing, by one or more processors, a program to provide tailored diagnostic information;
and
creating, by one or more processors, a virtual memory image of a system state, based on the memory dump, in the address space of the program, by creating a second hardware memory mapping of the hardware memory addresses of the address space of the program to the virtual memory addresses of the virtual memory image of the system state.

2 more elements

A computer system for tailoring diagnostic information specific to current activity of multiple threads within a computer system, comprising:

one or more computer processors, one or more computer-readable storage media, and program instructions stored on one or more of the computer-readable storage media which, when executed by at least one of the one or more processors, cause the at least one of the one or more processors to perform a method comprising:
creating a system dump, including main memory and system state information;
storing the system dump to a database;
executing, by one or more processors, a program to provide tailored diagnostic information;
and
creating, by one or more processors, a virtual memory image of a system state, based on the memory dump, in the address space of the program, by creating a second hardware memory mapping of the hardware memory addresses of the address space of the program to the virtual memory addresses of the virtual memory image of the system state.

3 more elements

A computer program product comprising:

one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, which when executed by a computer, cause the computer to perform a method comprising:
creating a system dump, including main memory and system state information;
storing the system dump to a database;
executing, by one or more processors, a program to provide tailored diagnostic information;
and
creating, by one or more processors, a virtual memory image of a system state, based on the memory dump, in the address space of the program, by creating a second hardware memory mapping of the hardware memory addresses of the address space of the program to the virtual memory addresses of the virtual memory image of the system state.
