  • Sharing live data with a non cooperative DBMS
    Patent number: 6879981
    Abstract: The log file maintained by a DBMS is used, possibly in conjunction with hardware that listens to the communication between a computer and the storage controller to create cache buffers and a locking mechanism that enable applications running on one computer system to consistently access the data maintained and updated by a different computer.
    Type: Grant

  • Resource sharing facility functions as a controller for secondary storage device and is accessible to all computers via inter system links
    Patent number: 5848241
    Abstract: A method and architecture for sharing data items using a resource sharing facility with a medium level cache accessible to all of the computers which are to share and connected to the computers by fast intersystem links. The resource sharing facility also acts as an ordinary secondary storage controller and in the resource sharing facility the control information and logic is provided which is needed for the mapping of cache data to the secondary storage and vice versa.

  • Method of sharing data in a heterogeneous computer system
    Patent number: 5758125
    Abstract: Heterogeneous computer systems are computer systems with different storage architectures, computer systems with different central processing units (CPUs), computer systems with different disk organization methods, computer systems with different access methods, computer systems that use different controller interfaces etc. These systems share data so that every one of the said computer systems can access the data independently, not relying on services from the others. A single copy of the data is maintained, as opposed to replicated data that is used, in some cases to overcome the same needs. Every system has direct access to the shared data, through the use of emulators that enable applications on every system to use the desired interfaces to the data, disguised as the ordinary local interfaces. An example is the accessing an IBM mainframe's DB2 data base from a UNIX environment.
