Job Management Cache for Persistent Status in Rebooting Systems

The patent applies preliminary action by creating a cache data section for each job before the job actually starts executing. This cache section pre-allocates storage space and establishes the job's initial state, so that when the system restarts after an unexpected shutdown, the job status information is already available in the cache rather than needing to be reconstructed. This resolves the contradiction by ensuring job status information persists through shutdowns while maintaining efficient access during operation.

The patent creates a copy of job status information in a persistent cache structure that survives system restarts. The cache data section serves as a duplicate storage mechanism that mirrors the in-memory job status, allowing the system to recover job status information after unexpected shutdowns without losing data. This copying approach resolves the contradiction between efficient in-memory tracking and persistent storage.

The patent segments job status information storage by creating individual cache data sections for each job, organized within a hierarchical namespace structure. Rather than maintaining a single large complex data structure, the system divides job information into discrete, manageable sections that can be independently accessed and managed. This segmentation resolves the contradiction by enabling comprehensive job management capability while keeping the system structure organized and manageable through modular organization.

The patent introduces a new dimension of persistent storage by creating a cache hierarchy that exists alongside the traditional in-memory job status structures. This additional dimensional layer of cache storage allows the system to maintain detailed job information without overloading the primary memory system, resolving the contradiction between comprehensive job management and system complexity by distributing information across multiple organizational dimensions.
