    Abstract: Methods, computer program products, and network authority devices are presented. The methods include, for instance: updating a source network with migration information of a virtual machine to redirect network traffic for the virtual machine to a destination network; and updating at least one remote network with the migration information of the virtual machine. In one embodiment, the updating includes updating the source network concurrent with a migration of the virtual machine to minimize interruption of the network traffic. In another embodiment, the updating includes updating a network device of the source network to forward the network traffic for the virtual machine to another network device of the destination network. In a further embodiment, the updating includes updating the source network to redirect the network traffic from at least one client on the at least one remote network.

    Abstract: A computer-implemented method, system and computer program product for improving accuracy and efficiency of auditing databases. A table, list or index of a database is analyzed to identify metadata, which includes time series data, user data, an Internet Protocol address and operation data. The identified metadata is associated with the corresponding record or row of the table, list or index from which the metadata was extracted. A determination is then made as to whether to record a raw data image associated with the record or row of the analyzed table, list or index based on the corresponding data operation. The identified metadata as well as the recorded data images, if any, are stored in a structured audit log. Auditing information is then obtained from a structured audit log based on matching the record or row identifier (RID) associated with the query with the RID associated with the structured audit log.

    Abstract: The illustrative embodiments provide for dynamic tuning of pre-initialization environment provisioning and management. An embodiment includes accepting a request from a group of applications to generate a performance-based index table for a workload based on a feature of the applications and generating the performance-based index table. The embodiment includes building a label feature by analyzing a static program feature of the applications and the performance-based index table. The embodiment includes constructing, using clustering algorithms, a model for provisioning a pre-initialization environment using the label features. The embodiment includes loading the applications into a pre-initialization environment. The embodiment includes introducing a selection policy for a switch in the pre-initialization environment in multiple applications to balance usage of a resource. The embodiment includes updating input to the model in response to monitoring a traffic of requests and collecting real time runtime data of the workload.

    Abstract: Methods, systems, and computer program products for de-duplicating data in executable files in a container image are disclosed. The method may include receiving a request to read a file in a first layer in a container image including a plurality of layers, wherein the file is a delta file which is from an updated executable file based on a base executable file, the base executable file is in a lower layer than the first layer in the container image, and the delta file includes block mappings between the updated executable file and the base executable file and different data between the two files, and blocks included in the two files are based on respective file structure. The method may also include restoring the updated executable file based on the delta file and the base executable file. The method may further include returning data in the updated executable file.

    Abstract: A call to an external interface to execute a target callee program associated with a first addressing mode in a secondary runtime environment (RTE) is received from a caller program associated with a second addressing mode running in a primary RTE. An address of a share area (SA) storing existing dynamic link object information in the primary RTE in storage is passed to the secondary RTE. The SA is accessible by both the caller program and the target callee program. In response to a request to load a dynamic link object by an initiating program during execution of the target callee program in the secondary RTE, an entry address of the dynamic link object is retrieved in the SA. The dynamic link object is loaded based on the retrieved entry address of the dynamic link object.
