摘要： A new file system is mounted to a mount point of an existing file system implemented in a computational system. A sentinel indicator is stored in the mount point. Prior to initiating an input/output (I/O) operation by a program, a determination is made by the program as to whether the sentinel indicator exists. In response to determining by the program that the sentinel indicator exists, the I/O operation is performed by the program. In certain alternative embodiments, in response to determining by the program that the sentinel indicator exists, the I/O operation is not performed by the program.

摘要： Provided are a method, system, and computer program product for creating a buffer point-in-time copy relationship for a point-in-time copy function executed to create a point-in-time copy relationship. A point-in-time copy function is initiated to create a new point-in-time copy relationship from a source volume comprising a first volume to a target volume comprising a second volume. Detection is made that the target volume of the new point-in-time copy relationship is a source volume of a first pre-existing point-in-time copy relationship having as a target volume a third volume. Detection is also made that the target volume of the first pre-existing point-in-time copy relationship is a source volume of a second pre-existing point-in-time copy relationship having as a target volume a fourth volume. A buffer point-in-time copy relationship having a source volume comprising the target volume of the first pre-existing relationship and a target volume comprising a fifth volume is created in response to detecting that the target volume of the new point-in-time copy relationship is the source volume of the first pre-existing point-in-time copy relationship and the detected that the target volume of the first pre-existing point-in-time copy relationship is the source volume of the second pre-existing point-in-time copy relationship.

摘要： A host reserves a device controlled by a controller that is coupled to the host. The controller starts a first timer, in response to a completion of input/output (I/O) operations on the device by the host, wherein the host continues to reserve the device after the completion of the I/O operations. The controller sends a notification to the host after an expiry of the first timer, wherein the notification requests the host to determine whether the device should continue to be reserved by the host. The controller starts a second timer, in response to receiving an acknowledgement from the host that the notification has been received by the host, wherein reservation status of the device reserved by the host is determined by the controller on or prior to an expiry of the second timer.

摘要： Systems and methods access non-compatible content repositories that are not natively accessible to a content management system. A metadata registry maintains metadata about content stored in both compatible and non-compatible repositories. For content in a non-compatible repository, the metadata indicates a repository interface capable of accessing the non-compatible repository. The content manager communicates with the repository interfaces to access the content in non-compatible repositories. The content manager may receive a request for content in a non-compatible repository, refer to the metadata registry to select a repository interface to employ, transmit a request for the requested content to the selected repository interface, and receive the requested content from the repository interface. A repository interface registry maintains information about available repository interfaces. Entries may be added to either the metadata registry and the repository interface registry, thus allowing the systems and methods to be extended to be able to access additional non-compatible repositories.

摘要： Provided are techniques for, in response to a source object being changed by a local transaction, generating log records, wherein each of the log records includes a sequence identifier, a source system entity modification timestamp, a target key, a target partition identifier, and values of source properties, wherein the source properties are identified using a target key indicator. The log records to process are selected based on a phase value of each log record, wherein the phase value is one of submitted, in-flight, and source system entity state change complete. One or more disjoint partitions are assigned to each of multiple processing instances. Under control of each of the multiple processing instances, it is determined whether to transmit a log record in the one or more disjoint partitions assigned to said processing instance and, in response to determining that the log record is to be transmitted, the log record is transmitted.

摘要： This invention relates to a computer simulated environment, such as a virtual world, and to the identification of a user entering the virtual world and user context in the virtual world model. An output of the virtual world model may be rendered using objects in the virtual world model. Previous versions of the rendered objects may then be located in associated user memory and specified differences between the rendered objects and the previous versions of the objects may be identified. A layer of the identified differences may then be rendered on the rendered output of the virtual world model.

摘要： Provided are a method, system, and computer program product for using information on Input/Output (I/O) sizes of accesses to an extent to determine a type of storage device for the extent from a plurality of storage devices comprising at least one of a first storage type and a second storage type. Performance information is processed for a time period for Input/Output (I/O) operations with respect to an extent maintained in at least one of the storage devices of the first storage type, wherein the performance information indicates an I/O size of the I/O operations with respect to the extent. A determination is made as to whether characteristics of the I/O operations other than I/O size indicate that the extent is eligible for migration to at least one of the storage devices of the second storage type. A determination is made as to whether characteristics of the I/O sizes of the I/O operations. A determination is made as to whether the characteristics of the I/O sizes of the I/O operations indicate that the extent should be migrated from the at least one storage device of the first storage type to at least one of the storage devices of the second storage type. The extent is migrated from one of the storage devices of the first type to at least one of the storage devices of the second type in response in response to determining that the extent is eligible for migration and that the characteristics of the I/O sizes indicate that the extent should be migrated.

摘要： A system and method link one or more disparate datasets with one or more spatial layers to create linked datasets. One or more data attributes common to the dataset and the spatial layer are identified, and the linkage is defined between the dataset and the spatial layer. The spatial layer and the linked data set then may be queried using a single input query. Features from the spatial layer and features from the linked dataset that match the query are generated for display.
