US 2020/0401463 A1 · SELF-MANAGED LOCK ACCESS

Abstract

An approach for providing exclusive access to a resource shared by a plurality of processes in a computer system. The approach includes a computer processor retrieving a process identifier for a first process attempting to access the resource, where the process identifier is uniquely assigned to each process of the plurality of processes requiring the resource with the computer system. The approach includes the computer processor using the process identifier for the first process and a mutual exclusion object that includes a lock position allowing exclusive access to the resource and a wait position for a next process to attain the lock position to provide exclusive access to the resource.

Dependent claims

A computer-implemented method for providing exclusive access to a resource shared by a plurality of processes in a computer system, the computer-implemented method comprising the steps of:

retrieving, by one or more computer processors, a process identifier for a first process attempting to access the resource, wherein the process identifier is uniquely assigned to each process of the plurality of processes requiring the resource in the computer system;
and
using, by one or more computer processors, at least, the process identifier for the first process and a mutual exclusion object to provide exclusive access to the resource, wherein the mutual exclusion object includes a lock position allowing exclusive access to the resource and a wait position for a next process to attain the lock position.

A computer program product for providing exclusive access to a resource shared by a plurality of processes in a computer system, the computer program product comprising:

one or more computer readable storage media;
and
program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to retrieve a process identifier for a first process attempting to access the resource, wherein the process identifier is uniquely assigned to each process of the plurality of processes requiring access to the resource in the computer system;
and
program instructions to use, at least, the process identifier and a mutual exclusion object to provide exclusive access to the resource, wherein the mutual exclusion object includes a lock position providing exclusive access to the resource and a wait position for a next process to attain the lock position.

3 more elements

A computer system for providing exclusive access to a resource shared by a plurality of processes in a computer system, the computer system comprising:

one or more computer processors;
one or more computer readable storage media;
and
program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
program instructions to retrieve a process identifier for a first process attempting to access the resource, wherein the process identifier is uniquely assigned to each process of the plurality of processes in the computer system;
and
program instructions to use, at least, the process identifier for the first process and a mutual exclusion object to provide exclusive access to the resource, wherein the mutual exclusion object includes a lock position providing exclusive access to the resource and a wait position for a next process to attain the lock position.
