Abstract: In a computer-implemented method for improving performance of a database, a processor receives batch jobs for a relational database. The batch jobs may include a first member with a first buffer pool, and a second member with a second buffer pool. The processor may also identify a first actual object and an isolation level for the batch jobs, generate related queries based on the first actual object and the isolation level, calculate a cost for the first member and the second member to run the batch jobs based on the related queries, and assign the batch jobs to the first member based on a lower calculated cost.

Abstract: Workflow optimization and re-distribution involves a target task set that is determined from a plurality of tasks in a workflow and based on a data flow of the workflow. The target task set is re-distributed to obtain at least one re-distributed task set. Each re-distributed task set indicates a respective data path different from a data path of the target task set and has a same function as the target task set. A simulated data flow for the at least one re-distributed task set is obtained by simulating data flowing in at least one data path indicated by the at least one re-distributed task set. An optimized task set for the target task set is determined based on the simulated data flow for the at least one re-distributed task set.

Abstract: A method, computer program product, and computer system are provided. Statistics for each columnar table are extracted from an online analytical processing (OLAP) database catalog. A transaction table map is created from transaction log records of an online transaction processing (OLTP) database. The transaction table map includes a counter of log records in a transaction and a timestamp indicating a longevity of the transaction. Based on the counter or the longevity exceeding a predefined threshold, the transaction is transformed, and sent to the OLAP database where it is replayed.

Abstract: A system may include a memory and a processor in communication with the memory configured to perform operations. The may operations include obtaining transaction logs in blocks from nodes of a data storage system. The operations may include, for each transaction log, splitting the transaction log into log entries, grouping log entries into groups associated with a same data source, and writing the log entries of the groups to empty blocks such that log entries from different groups do not share a same block. The operations may include identifying a same sequence of log entries from the written transaction logs and uploading first blocks of a first transaction log, including the same sequence of log entries, to an object-based storage without uploading second blocks of a second transaction log including the same sequence of log entries to the object-based storage.

Abstract: An approach for recommending an application of a software code update. The approach receives components of an executable program. The approach scans the components to divide the executable program into units. The approach creates a logical layer of entry lists, based on the units, for instantiations of the executable program. The approach loads the instantiations of the executable program based on the logical layers. The approach monitors the execution of the instantiations to increment counters based on executions of the units. The approach creates a heatmap of the executions based on the counters. The approach generates a recommendation to update the executable based on the heatmap.

Abstract: Embodiments relate to progressively validating access token. In response to intercepting an initial call for a transaction for a service from a client, a token is validated for the initial call of the transaction for the service, the validating including contacting an authentication sever and locally storing a time to live received for the token. In response to intercepting at least one successive call for the transaction for the service from the client, it is determined that the token for the at least one successive call is valid based on the time to live locally saved. The at least one successive call for the transaction for the service is permitted to pass without contacting the authentication sever.
