    Abstract: A method for validating control blocks in memory includes monitoring for operations configured to obtain storage space in memory. The method examines the storage space that has been obtained to identify control blocks stored in the storage space. These control blocks are then analyzed to determine whether the control blocks are valid. In certain embodiments, this may be accomplished by comparing the content of the control blocks to information in a validation table that indicates possible values and ranges of values for fields in the control blocks. If a control block is valid, the method records a date and time when the control block was validated. If a control block is not valid, the method generates a message indicating that the control block is not valid. A corresponding system and computer program product are also disclosed.

    Abstract: A method, system, and computer program product for managing data sets of a storage facility is disclosed. The method, system, and computer program product include determining, by analyzing a first data set, that the first data set includes a first record having padded data. To identify the padded data, the method, system, and computer program product include comparing at least a portion of the first record of the first data set with a second record of a second data set. Next, the method, system, and computer program product include removing, from the first record of the first data set, the padded data.

    Abstract: A method, system and computer readable medium for managing and profiling control blocks via a storage control block administration operation. More specifically, in certain embodiments, the control block administration operation includes identifying areas of storage that are currently being used by storage control blocks. When the areas of storage being used by the control blocks are identified, the control blocks are profiled. In certain embodiments, the profiles enable limits and recovery actions to be specified by the control block administration operation.

    Abstract: Method, system, and networked embodiments for processing PDSE extended sharing violations are provided. A single special page referred to as a “sync” page is added to the PDSE dataset. The sync page is loaded from DASD to local cache at PDSE dataset open and remains open until the last close of the PDSE dataset. The in-core version of the sync page maintains a list of index update records for all computer systems within a sysplex and the on-DASD version of the sync page maintains a list of index update records for all computer systems connected to shared DASD. By leveraging properties of the sync page, and more particularly by monitoring any divergence in the in-core and on-DASD sync pages, a PDSE error handling module can programmatically determine when a PDSE dataset has been accessed by a rogue system, diagnose the type of error associated with the rogue update, log and notice of all systems in the sysplex of the error (and eventually connected systems outside the sysplex) and, for certain types of errors, fix the PDSE dataset.

    Abstract: In one aspect of the present description, operations are described for detecting whether programming code of a first computer program has been modified by a second computer program. In one embodiment, the modification detecting includes registering a first section of programming code of the first computer program in a first registry data structure. To detect a modification, the registered first section of programming code may be validated. In one embodiment, the validating includes comparing the section of programming code actually located at the first memory address to the registered first section of programming code. In another aspect, various selectable remedial actions may be taken upon detecting modification of programming code of the first computer program. Other features and aspects may be realized, depending upon the particular application.
