Abstract: One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to training an AI model to predict status of a DBMS. The computer-implemented system can comprise a memory that can store computer executable components. The computer-implemented system can further comprise a processor that can execute the computer executable components stored in the memory, wherein the computer executable components can comprise a data ingestion component that can use testing data of an AI model to generate ingested data by randomly changing one or more records of at least one feature comprised in the testing data, wherein the ingested data can be used to compute a first ratio indicative of inequity of the at least one feature. The computer executable components can further comprise a training component that can train the AI model using at least the first ratio to predict a status of system.

Abstract: In computer methods and systems for operating a database management system using a catalog table collection module each table in the database management system is cataloged. Multiple tables are automatically dispatched into multiple consistency groups by collecting real-time statistics using a real time statistics module. Workload profile data of the database management system is generated using a workload profile collection module, and an optimized multiple consistency group definition for the database management system is generated using a transaction splitting analysis module.

Abstract: An automatic triggering alert for changing a controller proxy in a computer cluster environment can be received, based on monitoring the computer cluster environment and policy rules associated with the computer cluster environment. The triggering alert can be broadcast to a plurality of agents in the computer cluster environment. Candidate proxies among the plurality of agents can be determined. For each of the candidate proxies, a system health status based on a prediction model's forecast and a policy compliance score based on the policy rules can be determined. Based on the system health status and the policy compliance score associated with each of the candidate proxies, a new controller proxy among the candidate proxies can be selected for the computer cluster environment. The new controller proxy can be notified to perform management of the computer cluster environment.

Abstract: A system, method, and computer program product include: collecting runtime history capture data by a data agent operable on a computing device; performing a pre-analysis of entries in the history capture data, the history capture data including a plurality of database transactions corresponding to user tables, and providing formatted history capture data; clustering the formatted history capture data into clusters by data characteristics of interval groups; performing a post-analysis on the clusters and providing a unit data profile for capture data of the user tables; and dynamically updating capture policies corresponding to capture processes for the user tables, the updating based at least on the unit data profile provided by the post-analysis. In some embodiments the clustering is density based. Optionally, an alert is sent when capture process capacity is exceeded.

Abstract: Embodiments of the invention are directed to data replication in an active-active databases having a source site and a target site. Aspects include creating a subscription activation message in a capture address space, the subscription activation message having a timestamp after a latest committed timestamp of the active-active databases and transmitting the subscription activation message to a subscription activation module of the target site of the active-active databases. Based on a determination that one or more tables associated with the subscription activation message are inactive, aspects also include repairing the one or more tables. Based on a determination that all tables associated with the subscription activation message are active, aspects include initiate replication of the capture address space from the source site to the target site with a timestamp of the latest committed timestamp.

Abstract: Aspects include monitoring, by a controller, an operational status of a tracker system that is configured to track and record a current status of a job being executed and to report completion of the job to the controller. The recording includes storing two copies of the current status, where a first copy is stored in a shared memory location accessible by the controller. In response to determining, based on the monitoring, that the tracker system is operational, waiting to receive a job completion message for the job from the tracker system and performing a job completion action based on receiving the job completion message. In response to determining that the tracker system is not operational, obtaining the current status of the job from the shared memory location and performing the job completion action based on the current status indicating that the job has completed.

Abstract: Disclosed are techniques for migrating the execution of a task from a first host system to a second host system by copying a snapshot of data required for starting the execution of a task from memory of the first host system to memory of a coupling facility, monitoring the execution of the task on the first host system, and, upon detecting failure of the execution of the task on the first host system, initiating execution of the task on the second host system by copying the snapshot of data from the memory of the coupling facility to the memory of the second host system.

Abstract: Aspects of the present invention disclose a method for pasting based on semantic fragments. The method includes one or more processors in response to identifying a copy operation request, obtaining copied data. The method further includes splitting the copied data into a plurality of semantic fragments based on semantic analysis. The method further includes rendering the plurality of semantic fragments on a display of a computing device. The method further includes in response to identifying a user selection of at least one of the plurality of semantic fragments, determining whether to paste the at least one of the plurality of semantic fragments.
