Abstract: A system and method of dynamic class management includes starting a skeleton application by loading a main class of the skeleton application and executing the main class, detecting a request for a requested class made by a referencing class, loading a class file associated with the requested class from a local storage device when the class file is stored on the local storage device and the requested class is not loaded in memory of the virtual machine, loading the class file from a class storage unit when the class file is not stored on the local storage device and the requested class is not loaded in the memory of the virtual machine, updating an application class graph (ACG) to record a dependency of the referencing class on the requested class, and updating an object table when the request is associated with creation of an object of the requested class.

Abstract: An example system for distributing a workload of an application includes a class identifier that identifies a remotely instantiable class in an instruction. Execution of the instruction includes processing a workload. The example system also includes a distributor that selects a remote node to process a portion of the workload, sends a message to the selected remote node to cause (i) the selected remote node to instantiate the remotely instantiable class and (ii) the selected remote node to process the portion of the workload by invoking a method of the instantiated class, and receives a result of the processed portion of the workload.

Abstract: A mechanism for managing data in relational database management systems (RDBMS). The method includes receiving a structured query language (SQL) query to be executed on a relational database management system (RDBMS). The RDBMS includes a schema of tables divided into a plurality of partitions and the SQL query includes an operation of data to be executed on the RDBMS. The method also includes determining whether the SQL query is a valid SQLT query. The SQL query is a valid SQLT query when the SQL query includes a join operation applied to data from tables in a same partition of the plurality of partitions.

Abstract: A mechanism for preventing overload of application is disclosed. A method includes receiving a query submitted by a user, the query includes user identification (ID) and an operation to be processed by an application. The method also includes filtering user records to identify subset of the user records associated with the user ID and determining quality of service (QoS) ranking from the subset of the user records associated with the user ID. The method also includes submitting the query to the application when the determined QoS ranking is assigned with high ranking. The method also includes filtering query records to identify subset of the query records associated with the query when the determined QoS ranking is assigned with low ranking. The method further includes determining quality string (QS) rating associated with the subset of query records and providing a decision on the query in view of the determined QS rating.

Abstract: A processing device receives a request from a client for a specific service. Responsive to determining that the specific service is not running, the processing device converts a previously instantiated generic service into the specific service. To perform the conversion, the processing device assigns the generic service from a service pool for the specific service and renames the generic service based on a name of the specific service. The processing device additionally queries a directory service for specific service logic associated with the specific service. The processing device receives at least one of the specific service logic or a reference to the specific service logic from the directory service, and updates the generic service to include at least one of the specific service logic or the reference to the specific service logic.

Abstract: An example method of processing a query includes receiving a partial query including an identifier that identifies a full query corresponding to the partial query. The partial query is sent from a client and includes a command to select data from a database table stored in a database. The method also includes determining whether the table has been updated since a previous result set was sent to the client. The method further includes generating a partial result set including an indication of the updates to the table since the previous result set was sent to the client. The method also includes sending the partial result set to the client. The partial result set is an incomplete result set of the partial query.

Abstract: An example method for reducing data communications includes receiving, at a data hub, a first set of messages from a first device. Each message of the first set includes a value. The method also includes sending one or more messages of the first set to one or more devices. The method further includes receiving a second set of messages from a second device. Each message of the second set indicates whether a state change occurred in the second device for one or more values included in the first set. The method also includes computing a value interval based on the one or more values associated with the first set. Values within the value interval were indicated in the second set as causing a state change in the second device. The method further includes configuring the first device to transmit messages for values within the value interval.

Abstract: A method and apparatus for creating and using cached blocks of bytecode are disclosed. An example apparatus includes a virtual machine execution engine configured to load an input variable value in conjunction with starting execution of bytecode associated with an application. The execution engine is also configured to read a cache table entry stored in a class file related to the application. The cache table entry includes a demarcation of a selected portion of the bytecode of the application that is stored within a cache block, a cache block input variable, and a cache block output variable. The execution engine is further configured to compare the loaded input variable value to the cache block input variable. Responsive to the input variable value matching the cache block input variable, the execution engine is configured to skip execution of the selected portion of the bytecode and read the cache block output variable.

Abstract: A processing device translates a set of federated queries submitted to a federated data source server into a set of native data source queries for the particular type of data source using a federated data source connector for a particular type of data source, inputs the set of native data source queries for the particular type of data source into a component corresponding to the particular type of data source, marks the component in view of the set of native data source queries, and generates output indicating whether one or more of the set of native data source queries is not acceptable as input for the component. The marked component and the output indicate whether the federated data source connector for the particular type of data source includes an error.
