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.
