Abstract: A method, a system and a computer program product for hybrid computing system management are proposed. In the method, workload information associated with a set of application server instances running in a first computing system is obtained by a server controller in response to a scaling request for changing the number of instances in the set of application server instances from a request controller. The set of application server instances serves at least one application running in a second computing system. A scaling decision indicating whether to change the number of instances in the set of application server instances is determined by a predictor based on the workload information from the server controller. The second computing system is enabled by the request controller to handle requests associated with the at least one application for the set of application server instances based on the scaling decision.

Abstract: A computer-implemented method includes detecting, by a bridge container running inside a container scope, connection information about a first service instance running to provide a respective first service outside the container scope. A first virtual container is initialized inside the container scope. The first virtual container is connected to the first service instance, utilizing the connection information about the first service instance, to virtualize the first service instance inside the container scope. It is detected that that a first source container inside the container scope requires the first service of the first service instance. The first source container is connected to the first virtual container to enable the first source container to access the first service instance through the first virtual container.

Abstract: An example operation may include one or more of identifying a caller blockchain node and one or more callee blockchain nodes within a blockchain network and issuing, by the caller blockchain node, application programming interface calls to application programming interfaces corresponding to each of the one or more callee nodes, in response to a first application programming interface call being issued successfully, directing a smart contract associated with the caller blockchain node to initiate a distributed transaction involving the one or more callee nodes to perform the application program interface calls, the caller node issues application programming interface calls and the one or more callee nodes each performing application programming interface requests.

Abstract: According to one embodiment, a method, computer system, and computer program product for memory corruption diagnosis is provided. The present invention may include generating a pattern expression (PE) header file, wherein a plurality of common datatypes associated with a software program are pre-defined. The invention may further include generating a PE for each of the plurality of common datatypes, and generating a PE table by merging the generated PEs for each of the plurality of common datatypes. Upon discovery that memory corruption has occurred, the invention may include transmitting a recorded state of the software program as a core dump file to a server, and using a dump utility to identify overlay content of the core dump file. Lastly, the invention may include identifying a possible source program of the memory corruption by matching the PE tables against the illegally-written overlay content.

Abstract: Method and system are provided for providing instructions during remote viewing of a user interface. The method carried out at a host computer system includes: capturing an image of one or more application user interfaces as displayed at the host computer system; and serializing data of each application user interface to provide a map of each window class and containers and/or control elements of the window class, wherein a container has attributes and child control elements. The captured image and the map are transmitted to a remote computer system; and control element input instructions are received from a remote computer system for instructing an interaction with a control element.

Abstract: User interface (UI) language options are provided. A code statement in an object code of an application retrieves human language bundle value(s) for use in a UI element. Code is injected into the object code of the application to transmit a resource bundle name and key to the UI element for storage at a user value area of a control of the UI element.

Abstract: Embodiments of the present invention relate to methods, systems, and computer program products for distributed transaction management. In a method, a first transaction is performed, where both a first data in a first application system and a second data in a second application system are to be accessed in the first transaction. A second transaction is identified in response to a determination that the second data in the second application system fails to be accessed in the first transaction, the first data in the first application system being accessed in the second transaction during performing the first transaction. A value of the first data is determined based on status of the first transaction and status of the second transaction.

Abstract: A method for message delivery to a transaction processor is presented. The method may include receiving a message having transaction information. The method may also include determining if the received message is prohibited from delivery based on comparing the transaction information with a blacklist, wherein the blacklist is used to block messages. In response to determining that received message is prohibited from delivery, the method may then include refusing message delivery or delaying message delivery. In response to determining that the received message is not prohibited from delivery, the method may further include enqueuing the message in a request queue. The method may also include receiving a reply message with a transaction status update from the transaction processor. The method may then include updating the blacklist based on the received reply message with the transaction status update.

Abstract: Providing hyperlinks in presentations viewed remotely. A current user interface of an application being shared or recorded in a presentation for remote viewer computer systems is identified.
