Abstract: A method for managing a message communication system comprising providing a token log as a data structure that contains a user-extensible set of tokens and implied conditions under which specific tokens are considered valid. The method also includes creating a new token as a set of symbols and storing the new token in the token log together with information that implies one or more conditions under which the token is considered valid, which validity information implies one or more specific actions to be performed when a message accompanied by the new token experiences an event. The method further includes providing for distributing the new token to one or more external entities and providing a system operator with the ability to change a validity status of the token.

Abstract: System and method for efficient issuance of queries, such as DirXML script queries, by a policy for a value of an attribute of an object of the target system are described. In one embodiment, the method comprises, responsive to issuance by a policy of a query for a value of a designated attribute of a designated object of a target system, checking a result cache associated with the target system to determine whether the value for the designated attribute of the designated object is stored therein; responsive to a determination that the value for the designated attribute of the designated object is stored in the result cache, returning the value stored in the result cache to the policy; and responsive to a determination that the value for the designated attribute of the designated object is not stored in the result cache, querying the target system for the value of the designated attribute of the designated object.

Abstract: Dynamic metadata allows for metadata that can be configured for an application programming interface (API) after the API has shipped. Multiple entities can provide metadata for the same API or portions of an API. The metadata provided for an API can be set up for each application domain, allowing customization within a single process. Metadata can be provided in several ways, including traditional compiled code and declarative markup as well as databases and other more dynamic approaches. Metadata is separated from its runtime components, so that the metadata that is used by the runtime components can be changed. For example, metadata may be declared on the objects separately. The metadata is then tied back to the runtime components.

Abstract: A system, method and computer program product for storing configuration data for use in configuring a device while a program utilizing the configuration data is undergoing a revision at the device. The method includes a first step of providing a data structure indicating a manner in which configuration data is to be stored, and storing the data structure and current configuration data according to the data structure. Then, a revised software program in the device may identify the data structure and access a particular configuration data, along with its format; and, apply a conversion function that translates the stored current configuration data to a format compatible for use by the revised software. This is accomplished in a manner such that no configuration data is corrupted. The data structure includes data self describing the stored current configuration data, such that a conversion function can easily access the self describing information and render the stored configuration data platform independent.

Abstract: A web server configuration is audited by selecting a configuration file and a set of target servers to be audited. The configuration file includes configuration settings to be audited for, and expected values for the configuration settings. The configuration file may be reconfigured by a user to include appropriate configuration settings and expected values. The configuration settings and expected values are compared to actual values of the configuration settings for the target server. Audit results are determined based on the comparison. The results are included in a report with the corresponding configuration settings.

Abstract: Methods, computer programs, and database systems for performing a database query to join two or more tables on a condition are disclosed. Each table includes one or more join columns. Each of the join columns includes zero or more join-column values. The method includes excluding join-column values that do not satisfy the condition, using one or more value-count indexes and performing the database query on non-excluded join-column values.

Abstract: An system for segmenting strings into component parts for use with a database management system. A reference table of string records are segmented into multiple substrings corresponding to database attributes. The substrings within an attribute are analyzed to provide a state model that assumes a beginning, a middle and an ending token topology for that attribute. A null token takes into account an empty attribute component and copying of states allows for erroneous token insertions and misordering. Once the model is created from the clean data, the process breaks or parses an input record into a sequence of tokens. The process then determines a most probable segmentation of the input record by comparing the tokens of the input record with a state models derived for attributes from the reference table.

The multidimensional data includes a data cube having a dimension. The system further includes an executable software module that accesses the data store and generates hierarchy data describing a hierarchy of the dimension of the data cube. The software module generates the hierarchy data so that the hierarchy data is guaranteed to aggregate to totals represented within the data cube.

Abstract: A set of mechanisms handles communication with a Knowledge Store and its K Engine(s). The Knowledge Store (Kstore) does not need indexes or tables to support it but instead is formed by the construction of interlocking trees of pointers in nodes of the interlocking trees. The K Engine builds and is used to query a KStore by using threads that use software objects together with a K Engine to learn particlized events, thus building the KStore, and these or other software objects can be used to make queries and get answers from the KStore, usually with the help of a K Engine. Under some circumstances, information can be obtained directly from the KStore, but is generally only available through the actions of the K Engine. The mechanisms provide communications pathways for users and applications software to build and/or query the KStore. Both these processes can proceed simultaneously, and in multiple instances. There can be a plurality of engines operating on a KStore essentially simultaneously.

Conflicting properties may be merged according to a prioritized hierarchy such that each conflicting property may have a higher or lower precedence compared to the other conflicting properties.

Abstract: A number of members of a user defined type may be designated as delayable members. During an initial fetch of the type, the type may be returned from the database without the delayable members, thereby preserving valuable bandwidth and reducing the amount of time required to perform the initial fetch. Upon request, selected delayable members may be re-fetched from the database at a later time without returning the other members provided during the initial fetch.

Abstract: Systems, methods and program products for computing frequent value statistics such as frequent values in a column in a partitioned relational database, that may be employed across a number of nodes of a partitioned relational database and a case where a column is the single partitioning key of the database table as well as the case where the column is not the single partitioning key of the database table. The technique involves hashing column entries to a hash data set on a node, collecting the hash entries into another hash data set on a coordinating node into a combined hash data set, hashing entries from a table portion residing on the coordinating node into the combined hash data set and computing frequent value from the combined hash data set. Each hash data set is an array of counts and the combined hash data set is a combined array of counts.

Abstract: The present invention comprises a process for managing entity-relationship data for data objects persisted in a relational database. In particular, the process minimizes the number of database operations needed to maintain persistent referential integrity between data objects, thereby minimizing the number of times that a program accesses the database. In the preferred embodiment, the inventive process is implemented as an improved container program having a CMR engine that controls the persistence of data object relationships in a relational database. The improved container program comprises one or more referential integrity rules, which control the container program's response to a client object program's instructions that affect entity-relationship data.
