1. A method for managing the availability of compiled data in a logically partitioned computer system having a plurality of processors, comprising the steps of: defining a plurality of logical partitions of said computer system, each logical partition having a respective processor resource assignment, wherein each task executing in said computer system is assigned to a respective one of said logical partitions and wherein the definition of a plurality of logical partitions may be dynamically altered; automatically determining first and second discrete subsets of said compiled data within a first logical partition, wherein said first discrete subset of said compiled data can be rebuilt using a first set of resources assigned to said first logical partition within at least one predetermined recovery time limit; automatically storing said second subset of said compiled data in a form which does not require rebuilding of said second subset; automatically detecting a configuration change to said first logical partition which alters the processor resource assignment of said first logical partition; automatically determining third and fourth discrete subsets of said compiled data within said first logical partition, wherein said third discrete subset of said compiled data can be rebuilt using a second set of resources assigned to said first logical partition within said at least one predetermined recovery time limit, said second set of resources being the set of resources after assigned to said first logical partition after said configuration change, said second set of resources being different from said first set of resources; and thereafter automatically storing said fourth subset of compiled data in a form which does not require rebuilding of said fourth subset.
