Abstract: An embodiment includes deriving usage data associated with records of a database by monitoring requests to perform read operations on the records of the database. The embodiment generates record correlation data representative of correlations between respective groups of records of the database by parsing the usage data associated with the records of the database. The embodiment stores a plurality of records received as respective write requests during a first time interval in an intermediate storage medium. The embodiment identifies a correlation in the record correlation data between a first record of the plurality of records and a second record of the plurality of records. The embodiment selects, responsive to identifying the correlation, a first location in the database for writing the first record and a second location in the database for writing the second record based on a proximity of the first location to the second location.

Abstract: Embodiments of the present invention relate to password authentication. According to an embodiment of the present invention, a password associated with a user identification is received from a user device.

Abstract: In an approach for improving performance of a batch job running on database servers in an active-active architecture. A processor, responsive to a batch job being ready to be executed on a source database server, sends a first communication to a target database server with a synchronization start point. While executing the batch job, a processor utilizes a pre-lock function, pre-load function, and lock avoidance function to prevent lock conflicts. A processor, responsive to either the source database server or the target database server encountering a commit statement, suspends the respective database server and sends a second communication to ask if the other respective database server is ready to complete the commit statement. A processor, responsive to the other respective database server confirming its ready to complete the commit statement, completes the commit statement on both the source database server and the target database server.

Abstract: Database log writing is based on log pipeline contention. A determination is made as to whether contention in writing data to a log pipeline, which is used in writing data from memory to storage, is at a prespecified level. Based on determining that the contention in writing the data to the log pipeline is at the prespecified level, a split operation is automatically performed to create a new log pipeline.

Abstract: Provided is a method for determining data storage is insufficient for a program. A processor may receive a set of marked data associated with a set of source code. The processor may identify a scope of the code associated with the marked data. The processor may generate a first set of instructions for taking a first snapshot of a variable storage space associated with the marked data when entering the scope and a second snapshot of the variable storage space when exiting the scope. The processor may generate a second set of instructions for comparing the first and second snapshots to determine a usage amount of the variable storage. The processor may generate a third set of instructions for performing an action in response to the usage amount of the variable storage space exceeding a threshold. The processor may compile the code into an executable.

Abstract: Aspects of the invention include computer-implemented method that includes generating a preliminary control flow graph from memory dump data and compiler listing data in response to an exception event at a computing program. Code segments associated with each block of the preliminary control flow graph are translated to Boolean statements. Each Boolean statement is determined to be either satisfied or unsatisfied based on input values retrieved from the memory dump data. An edge property value of a first edge and a second edge of a plurality of edges of the preliminary control flow graph based are calculated based on a satisfaction of the Boolean statements. The edge property value of the first edge is compared to the edge property value of the second edge. The preliminary control flow graph is refined by deleting the first edge of the plurality of edges based at least in part on the comparison.

Abstract: Source code of a golden version and a next version of a program is received in which procedure calls are modified to call from an entry point table (EPT) with index numbers corresponding to procedure memory addresses. An executable defect-free golden version program and next version program with a defect are received. A first entry point table (first EPT) for the new version program and a second EPT for the golden version program are generated. A series of substitutions of procedures from the second EPT to the first EPT is performed and an order of substitutions includes: a module set, a module of the module set, a procedure set of the module, and a procedure of the procedure set. The defect producing procedure is identified by substituting in order until the defect is absent and proceeding to the next substitution in order.

Abstract: The present disclosure relates to searching for and committing low-frequency data to a database. An example method generally includes receiving, from a requesting application, a query for data from the data repository. A database system retrieves a set of indices associated with the data specified in the query from an index table in the data repository. Upon determining that the set of indices comprises a non-null set, the database system retrieves records associated with each index in the set of indices from a data table associated with the index table and returns the retrieved records to the requesting application.
