System and method for automating page space optimization

Abstract

An optimizing tool optimizes a computer system's page space by basing the page size on the amount of real memory in the computer system. The optimization tool determines the amount of real memory in the computer system. The amount of memory is multiplied by a multiplier to determine an optimal amount of page space to allocate. In one embodiment the multiplier used is two (2) so that the amount of page space is double the amount of real memory. The optimal page space is compared with the amount of page space currently allocated in the computer system. If more page space is needed, the optimization tool determines where on the computer system's disk space the additional page space should be added. In a UNIX embodiment, the optimization tool determines whether a non-root volume group exists on the system. A non-root group without a paging space is examined for a new paging space addition. If a non-root group is found, the paging space needed is added to the non-root group. If no such non-root group exists, then the optimization tool adds paging space to the default UNIX paging space logical group. An existing paging space is expanded instead of adding a second paging space to a root volume group disk.
