Apparatus, system, and method for maintaining a context stack

摘要

An apparatus, system, and method are disclosed for maintaining a context stack. A monitor module monitors a stack size after each monitor interval for a stack of a plurality of contexts. Each context defines communications between a process and a data set and comprises a pathway for communicating with the data set and a process identifier. A stack module deallocates a context that satisfies a stack policy from the stack if the stack size is within a buffer threshold of a maximum threshold.

1. A computer program product comprising a non-transitory storage device storing a computer readable program for maintaining a context stack, wherein the computer readable program when executed on a computer causes the computer to:
monitor a stack size after each monitor interval for a stack of a plurality of existing contexts that are not associated to a process of a plurality of processes, wherein each context is associable and reusable with a plurality of processes and comprises a pathway to a data set when not associated to any process of the plurality of processes, the pathway comprising a logical volume identifier and a logical address for the data set, the context defines communications between the process and the data set through the pathway when associated to the process, and each context is returned to the stack when not associated to the process; deallocate a context that satisfies a stack policy from the stack if the stack size is within a buffer threshold of a maximum threshold.
