    Abstract: A method for analyzing data corruption is disclosed. In one embodiment, such a method includes identifying a data set to analyze for data corruption. This data set resides on tracks of a volume. The method further determines, from control information associated with the volume, on which tracks of the volume the data set resides. The method reads content of the data set without opening the data set by performing full-track reads of the tracks. The method further determines an expected format of the content by analyzing the control information. An actual format of the content is compared to the expected format to identify areas of the data set that may be corrupt. A corresponding system and computer program product are also disclosed.

    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.

    Abstract: Provided are a computer program product, system, and method for determining an ordering to use to open and close programs that call other programs. A dependency file indicates for each calling program at least one called program called by the calling program, wherein a called program that calls another program also comprises a calling program. The dependency file is processed to determine an order in which the called programs are called by the calling programs. A determination is made from the order the called programs called by an invoked calling program. The determined called programs are invoked according to the order. The calling program is invoked in response to invoking the determined called programs. The order indicates the order in which the calling programs and the called programs are invoked so the called programs are invoked before invoking the calling programs that invoke the called programs.

    Abstract: System and method embodiments for monitoring data integrity among multiple sysplexes that share data sets on a DASD are provided. The virtual volume record (VVR) for each data set on DASD is configured with additional access fields that provide such information as the access mode (serial or multi-access), whether multiple systems have opened the data set, the names of an original sysplex and any additional sysplexes to open the data set, the names of the opening systems in each sysplex, job name and time stamp and a usage counter for each sysplex. Additional access logic in the OS on each system defines specific actions to be taken by the system OS when executing an “open” or “close” including reading and updating information in the additional access fields and generating error, warning or information messages to diagnostic logs. This allows serialization to be enforced among the sysplexes and for error messages to be issued for any system outside the original sysplex that tries to open the data set. This also enables allowing multiple sysplexes to have a data set open at the same time and to issue messages to that effect.

    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.
