International Classification:

G06F 9/44
G06F 7/00

US Classification:

717168, 707610, 707624

Abstract:

A system and method to automatically identify resources requiring upgrade in a hierarchical database management system. The system may include an input module to receive input identifying a single resource for upgrade. A comparator module may compare an active resource library to a staging library to identify additional resources for upgrade, and an incorporation module may incorporate the single input resource and the additional resources into an upgrade list. A generation module may then automatically derive a unit of change from this list, where the unit of change includes the single input resource as well as additional resources that interact with the input resource.

US Classification:

719312, 719313

Abstract:

An apparatus, system, and method for autonomously maintaining a single system image in a parallel systems complex. A computer program product causes the relevant systems in a parallel systems complex to receive requests with a global scope from a user. The request is sent to each IMS system in the sysplex, and each IMS system applies the resource information and logs the resource information for recovery. The request is written to a shared medium which IMS sysplex members can access. When an IMS member is brought online, the IMS member restores status information first from local recovery logs. The IMS member then checks the information against the global medium to determine if requests were issued while the IMS was offline. If so, the IMS inherits the information in the global medium before processing work. An IMS added into the sysplex applies the information from the global medium before processing work.

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1500

US Classification:

711165

Abstract:

A database management system is described. The system includes a computer storage medium having a primary storage medium and an overflow storage medium. The system also includes a manager for managing a plurality of data structures (queues) stored in the computer storage medium. The manager receives a request to store a data object in a target data structure. The manager determines whether an overflow mode condition currently exists. If an overflow mode condition does not currently exist, then the manager determines whether a combined size of all data structures stored in the primary storage medium plus a size of the data object is greater than a predetermined threshold. If a combined size of all data structures stored in the primary storage medium plus a size of the data object is greater than a predetermined threshold, then the manager enters an overflow mode. Also, the manager selects one or more data structures currently stored in the primary storage medium, and moves the selected data structures from the primary storage medium to the overflow storage medium. The overflow storage medium is then directly accessed to process any subsequent actions involving these data structures.

International Classification:

G06F 1730

US Classification:

395621

Abstract:

A computer program product comprising a computer useable medium having computer program logic recorded on it for enabling a processor in a computer system to interact with a shared storage medium comprising a ready queue is described and a staging queue. The computer program logic enables the processor to determine whether a data object is larger than available storage capacity of a working storage associated with an application. A public key is associated with the data object and is available to all applications. If it is determined that the data object is larger than available storage capacity of the working storage, then the computer program product enables the processor to generate a private key for the data object, enables the processor to divide the data object into N segments, enables the processor to cause segments 2 through N of the data object to be stored in the staging queue via the working storage (the private key is also stored with each of the segments 2 through N in the staging queue), and enables the processor to cause segment 1 of the data object, the public key, and the private key to be stored in the ready queue. The private key becomes available to all applications once stored in the ready queue.

Abstract:

Described herein is a computer program product comprising a computer useable medium having computer program logic recorded thereon for enabling a processor in a computer system to manage a plurality of data structures stored in a computer storage medium. The computer storage medium includes a primary storage medium and an overflow storage medium. The computer program logic enables the processor to receive a request to store a data object in a target data structure, and enables the processor to determine whether an overflow mode condition currently exists. If it is determined that an overflow mode condition does not currently exist, then the computer program product enables the processor to determine whether a combined size of all data structures stored in the primary storage medium plus a size of the data object is greater than a predetermined threshold. If it is determined that a combined size of all data structures stored in the primary storage medium plus a size of the data object is greater than a predetermined threshold, then the computer program product enables the processor to enter an overflow mode such that an overflow mode condition exists. Once in the overflow mode, the computer program product enables the processor to select one or more data structures currently stored in the primary storage medium, and enables the processor to move the selected data structures from the primary storage medium to the overflow storage medium.
