Abstract
Method, apparatus and article of manufacture for determining memory requirements for a partition manager based on a given configuration. In one embodiment, a quantity of memory required for each of a plurality of components is determined, where each component is a collection of function-related code portions. Then, a total quantity of memory required for the partition manager based on the quantities of memory required for the plurality of components is determined.
Claims18
A method for determining a memory requirement for a partition manager in a logically partitioned environment of a computer, comprising:
- determining a quantity of memory required for each of a plurality of components, where each component is a collection of function-related code portions;
- and
- determining a total quantity of memory required for the partition manager based on the quantities of memory required for the plurality of components;
- wherein the logical partition manager is configured to at least manage logical partitions present on the computer, each logical partition having a separate operating system.
A method for determining a memory requirement for a partition manager in a logically partitioned environment of a computer, comprising:
- providing a size report for each of a plurality of components, where each component is a collection of function-related code portions and where each size report of a given component specifies a quantity of memory required for the given component;
- and
- determining a total quantity of memory required for the partition manager based on at least (i) the size reports;
- and (ii) a particular configuration of the computer;
- wherein the logical partition manager is configured to at least manage logical partitions present on the computer, each logical partition having a separate operating system.
A computer, comprising:
- a plurality of resources including memory and at least one processor;
- a logical partition manager configured to at least manage one or more logical partitions present on the computer, each logical partition having a separate operating system;
- a size calculator configured to determine an amount of the memory needed by the logical partition manager at initial program load for a particular configuration and prior to accepting configuration requests from users;
- and
- a configuration manager configured to at least:
- determine whether the amount of memory needed by the logical partition manager is available for a particular configuration;
- and
- if so, accept the particular configuration.
