Shared memory autonomic segment size promotion in a paged-segmented operating system

A system, comprising:

• a processor;
• and
• a memory, wherein the memory includes a computer program product configured to perform operations for implementing a selected segment size of a shared memory object in a page segmented operating system, the operations comprising:
• providing a user selected shared memory object autonomic promotion feature to receive a user input enabling a selected segment size;
• receiving a request for a shared memory object of a user application;
• accessing the user selected shared memory object autonomic promotion feature to identify a user selection;
• setting a segment size for the request for the shared memory object based on the user selected shared memory object autonomic promotion feature, and
• creating the shared memory object having one or more segments with the set segment size.

A computer program product for implementing a selected segment size of a shared memory object in a paged-segmented operating system, the computer program product comprising:

• a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to perform an operation comprising:
• providing a user selected shared memory object autonomic promotion feature to receive a user input enabling a selected segment size;
• receiving a request for a shared memory object of a user application;
• accessing the user selected shared memory object autonomic promotion feature to identify a user selection;
• setting a segment size for the request for the shared memory object based on the user selected shared memory object autonomic promotion feature, and
• creating the shared memory object having one or more segments with the set segment size.
