摘要： In a method for managing resources in a virtualized computing environment, a command to initiate execution of an operating system image dump process for a logical partition of the virtualized computing environment is received while the logical partition is in a process of terminating. One or more resources that are allocated to the logical partition that will not be utilized by the logical partition during execution of the operating system image dump process are determined. A notification to a hypervisor program in the virtualized computing environment is sent. The notification identifies the one or more resources. One of the one or more resources is reallocated. The operating system image dump process is executed.

摘要： A method, computer program product and computer system for coordinating data collection from a component of a data processing system is disclosed. The component registers with a dispatcher, wherein the component is a computer resource of the data processing system and is configured to accept at least one query, and the registration comprising data types handled by the at least one component, wherein the dispatcher is allocated computer resources of the data processing system. The component receives from the dispatcher a notification to perform the query against specified data structures, wherein the query comprises an action. The component, responsive to receiving notification, determines whether data structures of a data type specified in the query are handled. The data processing system runs the query to determine whether the query is satisfied. The data processing system executes the action.

摘要： A mechanism is provided for automatically closing a file or a device. A service routine monitor monitors a request received from either an application that opened the file or a device driver that readied the device. The service routine monitor determines whether the file or the device has been accessed within a predetermined time interval. Responsive to the file or the device failing to be accessed within the predetermined time interval, the service routine monitor sends a call to the application that opened the file or the application or a higher level device driver that requested that the device driver ready the device. Responsive to a response from the application or the higher level device driver indicating that the use of the file or the device is no longer needed, the service routine monitor closes the file or quiesces the device.

摘要： A computer implemented method, an apparatus, and a computer usable program product for tracking device driver requests in a data processing system is provided. A controller receives a request from a device driver. The controller associates a timestamp and at least one pointer to the request, wherein the timestamp indicates a time the request is received by an operating system. The controller then links the request from the device driver in a queue in the operating system, wherein the pointer identifies the location of the request in the queue.

摘要： A system for balancing component load. In response to receiving a request, data is updated to reflect a current number of pending requests. In response to analyzing the updated data, it is determined whether throttling is necessary. In response to determining that throttling is not necessary, a corresponding request to the received request is created and a flag is set in the corresponding request. Then, the corresponding request is sent to one of a plurality of lower level components of an input/output stack of an operating system for processing based on the analyzed data to balance component load in the input/output stack of the operating system.

摘要： Page faults during partition migration from a source computing system to a destination computing system are reduced by assigning each page used by a process as being hot or cold according to their frequency of use by the process. During a live partition migration, the cold or coldest (least frequently used) pages are copied to the destination server first, followed copying the warmer (less frequently used) and concluded by copying the hottest (most frequently used) pages. After all dirtied pages have been refreshed, cutover from the instance on the source server to the destination server is made. By transferring the warm and hot pages last (or later) in the migration process, the number of dirtied pages is reduced, thereby reducing page faults subsequent to the cutover.
摘要翻译： 根据进程的使用频率，通过将进程使用的每个页面分配为热或冷来减少从源计算系统到目标计算系统的分区迁移期间的页面错误。 在实时分区迁移期间，首先将冷或最冷（最不常使用）的页面复制到目标服务器，然后复制加热器（较少使用），并通过复制最热（最常用的）页面来确定。 在刷新所有脏污页面之后，将从源服务器上的实例切换到目标服务器。 通过在迁移过程中最后（或更晚）传送热页和热页面，减少了脏页数，从而减少了割接之后的页面错误。

摘要： A sync manager invokes a scheduled sync task that includes filter attributes for filtering a plurality of memory pages into a subset of memory pages. The sync manager selects file pointers that correspond to a plurality of files and traverses through the files using the selected file pointers. While traversing, the sync manager extracts file attributes for each of the files and, in turn, filters the files by comparing the filter attributes with the extracted file attributes. The sync manager then extracts memory page identifiers that correspond to the filtered files and synchronizes a subset of memory pages using the extracted memory page identifiers.

摘要： A method, a system and a computer program product for storing one or more volume attributes in a database. The system receives one or more volume attributes which are associated with one or more volumes within a storage system. One or more search terms are assigned to the volume attributes. The one or more volumes and one or more volume attributes are dynamically associated with a location of the one or more volumes. The system assigns the one or more search terms, the one or more volume attributes, and the location of the one or more volumes to the database. The database is stored at a local database and/or an external database. When one or more of the volume attributes are identified during an inquisition for the one or more volumes, the volumes are dynamically retrieved from one or more of the local database and/or an external database.
