  • Publication number: 20130060795
    Abstract: Performance of database systems may be improved by reducing the processing performed with each database query. For example, when a database query, such as a SQL statement, is executed with a first set of values, the query may be stored as a prepared statement and parsed and optimized as a section. When a similar database query is executed with a new set of values the section may be re-executed with the new set of values without re-parsing or re-optimizing the prepared statement. A similar database query may continue to be executed with new sets of values until the section is invalid because of an alteration to the table definitions of the database schema.

  • Publication number: 20130060732
    Abstract: Altering tables in a database system may be difficult because the tables may only be altered when all connection to the tables have been released. A free resources parameter may be set on in a management system for the database system to specify that resources should be attempted to be released. Connections to the database may be closed earlier that conventionally closed. For example, connections that are idle may be released. Once the connections have been released the database may be altered and the free resources parameter turned off. The free resources parameter notifies the database system of a pending alteration and allows the database to gracefully close connections to provide an opportunity for the alteration to occur.

  • Publication number: 20120143912
    Abstract: Legacy database engines may be extended through the use of callback extension handlers on the client. For example, regular expression matching and arbitrary user-functions may be implemented in a legacy database engine without replacing the engine. A pattern string may be provided to the legacy database engine by a client with a pattern matching prefix. When the legacy database engine encounters the prefix, the database engine executes a callback to the client with a value from the database for pattern matching. The client performs the pattern matching through, for example, regular expressions, and returns a match status to the database engine. The process may be repeated for several rows of a table in the database and a dataset compiled by the database engine and returned to the client.

  • Publication number: 20120140993
    Abstract: Biometric authentication is enhanced by prompting an individual to perform an action challenge. For example, when an individual provides a facial picture for facial recognition to access secure data the individual may be prompted to provide a second picture of the individual performing an action. In one case, the individual is prompted to provide a second picture with an eye closed or an open mouth. The action challenge improves security by preventing attackers from spoofing an individual's biometric information. The enhanced biometric authentication may be used on mobile devices, such as mobile phones and laptop computers, to provide access to secure data, such as bank account information.

  • Publication number: 20120143927
    Abstract: An in-memory document model may be created from a markup language document while parsing the markup language document. The model includes small fixed-size memory structures allocated from a single larger memory pool. The model stores the data contained in the markup language document and the hierarchical relationship between the data items in the markup language document. Thus, random access to the markup language document is achieved without further access to the document and without the overhead of language-specific object construction. When an object-oriented computer program instance references the document model, a language-specific object may be constructed from the model including a pointer to an element of the model. The document model may be created when parsing extensible markup language (XML) documents.

  • Publication number: 20120131439
    Abstract: A dynamic document template having static data, dynamic data, and/or procedural statements may be called by an application on a server. The dynamic document template is separate from the application program and is processed to form an interim script, which is then executed by a host computer system. The script generates document records in HTML or XML format that are output to a document. The data and procedural statements in the dynamic document template may be distinguished through interpreting mark-up language surrounding the data and procedural statements. The dynamic document templates execute in a separate namespace from the application and preserve the state of data in the application. A given application may call more than one dynamic document template to generate different portions of the output document. Additionally, the dynamic document templates may be replaced with new templates without affecting the application.

  • Publication number: 20120110297
    Abstract: A soft partitioning system for allowing multiple virtual system environments to execute on a single platform may include I/O service partitions (IOSPs). The IOSPs operating in a separate virtual memory space on the platform and service disk and network requests from multiple guests. The IOSPs provide translation from virtual addresses to physical addresses such that from the point of view of the guest the virtual addresses used by the guest appear to be physical addresses. The IOSP may be implemented in a Linux kernel. The address space of the IOSP may be extended to include DMA memory sections such that the Linux kernel does not include all of the guest's memory. The IOSP may operate on hardware that does or does not support virtualization technology for directed I/O.

  • Publication number: 20120102368
    Abstract: Error information may be made quickly and easily accessible to an administrator by logging communications attempts in the operating system of a server. When the interface processor resides outside of the operating system, the interface processor may provide indications to the operating system of communications attempts. Specifically, the interface processor may provide message packets to the pass-through communications processor of the operating system when SSL/TLS communications attempts fail to establish secure communications sessions. The message packets may include information useful for diagnosing errors in SSL/TLS communication failures such as errors in the creation and management of certificates, certificate trust, private and public keys, and/or cipher suites. The communications logs in the operating system may be reviewed and/or analyzed by an administrator with a log trace analysis application.

  • Publication number: 20120078833
    Abstract: Business rules may be defined for camera placement in a video surveillance system, such as a system monitoring an airport. The business rules may be logical rules having an if-then format. For example, the if portion of the business rule may include a category, a surveillance area, and a business case for a proposed location. The then portion of the business rule may specify a recommendation to install an additional security camera in the video surveillance system at the proposed location. The recommendation may be calculated using a spreadsheet. The business rules provide justification for recommending a new camera placement and provide sound reasoning to assist in decision making when considering new camera locations in a video surveillance system.

  • Publication number: 20120072638
    Abstract: Trapping and/or processing of read/write accesses to hardware devices represented to the host through a memory mapped space may be performed without knowledge of the processor's instruction set or semantics of the processor's instructions. A single step routine may be executed to recognize page faults occurring from read/write accesses to emulated memory pages and causing the guest to retry the operation on a single step buffer. The hypervisor may perform post-operation processing on the single step buffer after the guest retries and completes the read or write access. For example, on a read request, the single step routine may place the guest value in the single step buffer for reading by the guest on a retry operation. On a write request, the single step routine may direct the guest to retry the write operation into the single step buffer.

  • Patent number: 6760719
    Abstract: Heterogeneous data at a plurality of remote nodes is accessed automatically in parallel at high speed from a user site using a simple script request containing a data source object name wherein the heterogeneous data is treated as a single data source object, the script further containing at least one method to be performed on the data source object. Respective agent processes at the user site and at the remote nodes automatically generate descriptor files containing metadata corresponding to the data source object. The user site agent breaks the user-generated script into new scripts appropriate for execution at the remote nodes. A messenger process transmits the new scripts to the appropriate remote nodes where respective agent processes respond to automatically access the appropriate data and execute specified methods upon it.

  • Patent number: 6415299
    Abstract: A computer-implemented method is provided for merging a source version into a target version of a model in an object oriented repository. The method comprises the steps of building a first list as a collection of versions that occur only in a history of the source version; and, building a second list as a collection of versions that occur only in a history of the target version. Next, a dual history is created as a union of the first and second lists. After this, either the first or the second list is identified as the non-preferred history wherein either the source or the target version is preferred. The first list is then added to the history of the target version. Any conflicts occurring in the dual history are next reported; and, such conflicts are resolved by adding the target version to a list of end versions on each conflicting attribute value and link occurring in the non-preferred history.
