摘要： An application program interface at a local processor enables transparent access to both a local database and a remote database. The remote database includes (i) a remote DBMS which segregates data into distinct remote datatype categories and (ii) remote data functions which define functions that are executable by the remote DBMS with respect to categories of remote datatypes. The local processor includes a memory which stores (i) a local DBMS that includes local datatypes which segregate locally stored data into local datatypes; (ii) local functions which define actions that are executable by the local DBMS with respect to defined categories of the local datatypes, and (iii) tables which store a mapping between local datatypes and remote datatypes, and local functions and remote functions. The mapping between at least one local datatype and at least one remote datatype indicates that the remote datatype is to be transformed into a local defined datatype that is different than the remote datatype. A local processor employs the table to convert a received instance of the at least one remote datatype to a mapped local datatype and subjects data comprising the instance of the remote datatype to a local function which is not executable for the remote datatype. The application program interface further enables specification of a function to be carried out at the remote database with respect to data stored thereat, which function is not readily performable by the local processor.

摘要： The performance of a heterogeneous, distributed database system is optimized by supporting both block fetch operations and positioned update operations. Specifically, a data block is fetched from a target database management system (DBMS), and a positioned update instruction issued by a client is processed. The positioned update instruction, when executed by the target DBMS, enables the target DBMS to modify a row contained in the data block and addressed by a cursor as the cursor is perceived by the client. Also, performance of the database system is optimized by identifying database statements that reference invariant host variables, and modifying such database statements by replacing in the database statements the host variables with literal values equivalent to the host variables.

摘要： A system and method for compensating for functional differences between heterogeneous database management systems, wherein data associated with a client is distributed among the heterogeneous database management systems, is discussed. The system simulates support of multiple pending actions on a single connection in any of the heterogeneous database management systems which does not support multiple pending actions on a single connection. Also, the system: (1) simulates support of cursors declared "with hold" in any of the heterogeneous database management systems which does not support cursors declared "with hold"; (2) simulates support of positioned update actions in any of the heterogeneous database. management systems which does not support positioned update actions; (3) simulates support of host variables in any of the heterogeneous database management systems which does not support host variables; and (4) compensates for security log-in procedure differences between the heterogeneous database management systems.

摘要： An automated method is provided for optimizing a query for retrieving data from a relational database in a computer relational database management system. The method uses rules for identifying queries for which duplicates are a factor in retrieving the proper data from the database. The method then merges queries with table expressions, views and subqueries when possible without causing duplicates to be unnecessarily retrieved.

摘要： A virtualization based system comprises a host and a plurality of virtual machines that may each comprises a guest memory. A virtual machine monitor has access to underlying platform hardware in the system and may control physical resources in the platform. The platform hardware comprises a processor and a memory coupled to the processor. Further, the VMM may manage guest software including guest operating systems running on the virtual machines. A binary translation logic may replace guest memory writing instructions corresponding to a hot spot in guest application with translated codes to generate a mirrored content for the guest memory. The binary translation logic may combine one or more of the guest memory writing instructions in a region and keep the region atomic. The processor may execute the translated codes in an atomic region together to write a content in the guest memory and a mirrored content in a mirroring memory. The VMM may allocate a memory region in the host memory for the mirroring memory. The guest memory comprises one or more guest memory pages and the mirroring memory may comprise one or more mirroring memory pages. The VMM may add an offset to a virtual address of a guest memory page to obtain a virtual address of a mirroring memory page. The VMM may manage or emulate a guest page table comprising a mapping between virtual address to guest physical addresses for the guest memory. The VMM may synchronize a shadow page table with the mapping in the guest page table. The shadow page table comprises a mapping of virtual addresses to host physical addresses for the guest memory and a mapping of virtual addresses to host physical addresses for the mirroring page. Upon a memory failure in the guest memory page, the VMM may restore the content of the corrupted guest memory page from the mirroring memory page.
