Disclosed are a method, system and computer program product for progressively improving the fit of a pool of reusable environments to requirements of programs in a computer system. The method comprises steps of: providing a first environment for a first program; responsive to initiation of a second program, making a determination whether creation of a new environment is a best response; responsive to a determination that creation of a new environment is a best response, creating a new environment for the second program; responsive to a determination that creating a new environment is not a best response, testing the pool for a best fit environment; and adding elements to the best fit environment to match requirements of the second program, unless the best fit environment already matches the requirements of the second program.

Method, program product and computer system for progressive improvement of an environment pool

A logically partitioned data processing system has a policy defining responsive actions to be undertaken by a process in one partition because of a monitored failure of an operating system in another partition. When such a failure occurs, the monitoring partition, if authorized, automatically communicates with a hypervisor to initiate the responsive actions on the failing partitions to reset and/or reconfigure that failing partition. Communication of action request between the partition and the hypervisor is accomplished without operator intervention, through a Service Call Logical Processor interface.
