Embodiment Construction

[0031] Many of the functional units described in this specification are labeled as modules in order to more particularly emphasize their implementation independence. A module may comprise hardware circuitry such as one or more processors with memory, very large scale integration (VLSI) circuits, gate arrays, programmable logic, and / or discrete components. Hardware circuits may perform hard-wired logic functions, execute computer readable programs stored on tangible storage devices, and / or perform programmed functions.

[0032] Reference throughout this specification to "one embodiment," "an embodiment," or similar language means that a specific feature, structure, or characteristic described with respect to the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases "in one embodiment," "in an embodiment," or similar language throughout this specification all refer to the same embodiment.

[0033] Furthermore, the described...

Abstract

In a dynamic address tracking system, a token module creates a token for a job that accesses data in a storage system comprising a plurality of storage devices. The token comprises a job name. The job is a batch job. A storage module stores location information for the data accessed by the job in a token table. The location information is indexed by the token. In addition, the location information includes an input / output device name, an address space, a data set name, and a storage device name. A communication module receives a diagnostic command comprising the job name. The token module reconstructs the token using the job name. The storage module retrieves the location information indexed by the token in response to the diagnostic command.

Description

technical field [0001] The present invention relates to address tracking, and more particularly, to dynamic address tracking. Background technique [0002] Enterprise data processing systems often include storage systems. A storage system may include multiple storage devices and multiple input / output (I / O) devices distributed over one or more sites. [0003] Hosts can access data from the storage devices of the storage system. Typically, hosts access data as part of a batch job. Multiple hosts can access the storage system at the same time. [0004] When there is erroneous access to data in the data in the storage system, an administrator may wish to track incoming and outgoing access to that data. Unfortunately, because a storage system includes a large number of storage devices and I / O devices, it is not possible to perform job tracking and / or or data dump. Contents of the invention [0005] In light of the above discussion, there is a need for an apparatus, system...
