    Abstract: A method, system, and computer program product for mitigating adjacent track erasures in hard disks, includes: determining input/output (I/O) characteristics for a plurality of blocks on a hard disk; assigning the plurality of blocks to a plurality of categories of I/O characteristics by the processor; and clustering content of the blocks assigned to the same category in one or more continuous tracks on the hard disk. Each block is assigned to one category. Blocks with similar I/O characteristics are clustered on one or more continuous tracks. By performing this clustering, blocks with a high number of I/O operations are grouped and stored on fewer tracks than if they were scattered across numerous tracks. This reduces the number of tracks experiencing a high number of I/O operations, and in turn, the amount of refreshing of adjacent tracks is reduced.

    Abstract: One method includes assigning a pointer from multiple logical blocks to the same original physical block if the multiple logical blocks include the same data. The method further includes receiving a command to write data to the first logical block and determining if the first logical block is a frequently accessed logical block. If the first logical block is a frequently accessed logical block, ownership of the original physical block is assigned to the first logical block. If ownership is established, the method includes copying any data stored in the original physical block to a new physical block, assigning a pointer from a second logical block to the new physical block, and performing the write command on the original physical block. A system includes a processor for performing the above method. One computer program product includes computer code for performing the method described above.

    Abstract: An approach for specifying data in a standards style pattern of Service-Oriented Architecture (SOA) environments is provided. The approach implemented in a computer infrastructure, includes defining an interface including one or more local data elements and one or more references to one or more common data elements, of a service, the one or more common data elements being defined in a library for a plurality of services. The approach further includes configuring a data definition file (DDF) which indicates whether each of the one or more local data elements and the one or more common data elements is mandatory for the service. The approach further includes validating one or more data elements from a consumer as mandatory for the service based on the configured DDF.
