Abstract: A first run-time environment executing a first instance of an application, and a second run-time environment executing a second instance of the application are established. An indication of an impending commencement of a reduced-capacity phase of operation of the first run-time environment is obtained at a service request receiver. Based at least in part on the indication, the service request receiver directs a service request to the second instance of the application.

Abstract: Storage systems track free blocks using various data structures and maps. For instance, free block maps may contain data blocks with values that indicate whether a block is free or not. When an operation results in a block being freed, the relevant data block in the maps must be written during an I/O operation to update the value. Large numbers of updates my occur after an operation that frees a large numbers of blocks, which can lead to performance degradation. Accordingly, disclosed are systems and methods for deferring updating of free block data tracking structures using logs.

Abstract: The disclosed embodiments provide a method, apparatus, and system for selecting, based on feedback from previous garbage collections, a portion of a referenced memory area for garbage collection within a time window. During the execution of a software program, the system selects a given portion of a referenced memory area on which garbage collection can be completed within the given time window and attempts to complete garbage collection on at least the given portion of the referenced memory area before the end of the given time window. Next, the system selects, based on the results of the garbage collection performed during the given time window, a subsequent portion of the referenced memory area on which garbage collection can be completed within the subsequent time window and attempts to complete garbage collection on at least the subsequent portion of the referenced memory area before the end of the subsequent time window.

Abstract: An application programming interface (API) may include an initiator configured to initiate a guest safepoint via an action represented in a guest language executed on a virtual machine, provide a safepoint action to a group of guest threads, synchronize the guest threads such that each guest thread in the group executes the safepoint action once all guest threads in the group enter the guest safepoint, and synchronize the guest threads such that each guest thread in the group exits the guest safepoint once all guest threads in the group complete execution of the safepoint action. The API may also include a guest configured to determine whether a guest safepoint is initiated, enter the guest safepoint, execute the safepoint action while execution of a guest action is paused, and exit the guest safepoint and resume execution of the guest action once the safepoint action completes execution.

Abstract: According to one embodiment, a control unit writes data in a write buffer to a first semiconductor storage device, and requests the first semiconductor storage device to start a background operation. The control unit writes the data to a second semiconductor storage device, and requests the second semiconductor storage device to start a background operation. When the first semiconductor device is in a busy state because of the write operation or the background operation, the control unit reads data from either the second semiconductor storage device or the write buffer.

Abstract: A method for collection instance resizing. The method may include identifying at least one collection object within a collection framework of a virtual machine. The method may also include determining the at least one identified collection object satisfies at least one preconfigured criteria. The method may further include determining a garbage collection cycle count associated with the at least one identified collection object exceeds a preconfigured threshold. The method may also include determining an occupancy ratio associated with the at least one identified collection object is less than a preconfigured shrink threshold. The method may further include restructuring the at least one identified collection object based on the at least one identified collection object satisfying the at least one preconfigured criteria, the garbage collection cycle count exceeding the preconfigured threshold, and the occupancy ratio being less than the preconfigured shrink threshold.

Abstract: Systems and methods may provide for identifying an object in a managed runtime environment and determining an age of the object at a software level of the managed runtime environment. Additionally, the object may be selectively allocated in one of a dynamic random access memory (DRAM) or a non-volatile random access memory (NVRAM) based at least in part on the age of the object. In one example, the data type of the object is also determined, wherein the object is selectively allocated further based on the data type.

Abstract: According to an aspect, a user interface is provided for assisting a user with identifying parameters for starting an application that utilizes real-time garbage collection (GC). The parameters include a fixed heap size and a GC central processing unit (CPU) utilization. Responsive to receiving a request from the user, the user is provided with options for profiling the application. The profiling includes executing the application. The options include targeting the GC CPU utilization to meet real-time requirements, targeting the heap size to meet the real-time requirements, and targeting a balance between the GC CPU utilization and the heap size to meet the real-time requirements. Responsive to detecting a selection of an option by the user, the application is profiled according to the option selected. The user is presented with results of the profiling via the user interface. The results include values for the parameters.

Abstract: Elements of a database object are removed. The database object is stored as a plurality of different object portions, where each object portion is associated with one or more versions of transaction identifiers stored separately from the database object. An oldest transaction identifier is determined for a transaction for which data portions of the database object remains visible. Each object portion is examined and object portions with a threshold amount of data to remove are determined based on a comparison of the transaction identifiers for those object portions and the oldest transaction identifier. Data from the database object are removed in response to a sufficient quantity of data is to be removed from object portions containing the threshold amount of data.
