摘要： User interactions with a database storage system allow creation of virtual databases based on point-in-time copies associated with a source database. Multiple point-in-time copies are obtained for each source database. A point-in-time copy retrieves data changed in the source database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system and mounting the files on a database server allowing the database server to access the files. User interactions allow the user to specify the source database, a point in time associated with the source database and a destination server to create the virtual database. User input can specify other attributes associated with the virtual database including the file paths, database parameters etc. The user can specify schedules of various actions, including making and retention of point-in-time copies.

摘要： A method, system and computer program product for managing data replication for data groups stored in a first storage device. A polling interval, a maximum bandwidth and a bandwidth tolerance available for data replication is defined. A priority and a status for each data group is defined. The data replication is started in the polling interval, for the data group with highest priority in the pending status to a second storage device connected to the first storage. The rate of data transfer during a polling period is determined by dividing the total data transferred during the polling interval by time period of the polling interval; and bandwidth utilization is determined for data replication by comparing rate of data transfer with maximum bandwidth. If the bandwidth utilization is less than the maximum bandwidth available then another data group is selected for replication. If the data bandwidth utilization is more than the maximum bandwidth available then selected data groups replicating are paused.

摘要： Techniques are described herein for synchronizing cluster time. According to one technique, a master node is appointed in a cluster. Other “slave” nodes periodically synchronize their clocks with the master node. To synchronize its clock with the master node, a slave node sends a timestamped message to the master node, which also timestamps the message and sends the message back to the slave node, which then timestamps the message again. Based on the timestamps, the slave node is able to determine the difference between the master node's clock's time and slave node's clock's time, compensating for the message travel time between master node and slave node. Depending on various circumstances, and based on the determined difference, the slave node adjusts its clock so that the time indicated by the slave node's clock at least begins to approach more closely the time indicated by the master node's clock.
摘要翻译：这里描述了用于同步集群时间的技术。根据一种技术，在簇中指定主节点。其他“从”节点周期性地将其时钟与主节点同步。为了将其时钟与主节点同步，从节点向主节点发送时间戳消息，主节点还对消息进行时间戳，并将消息发送回从节点，从节点再次对消息进行时间戳。基于时间戳，从节点能够确定主节点的时钟和从节点的时钟时间之间的差异，从而补偿主节点和从节点之间的消息传播时间。根据各种情况，根据确定的差异，从节点调整其时钟，使从节点的时钟指示的时间至少开始接近主节点时钟指示的时间。

摘要： A computer implemented CPU utilization prediction technique is provided. CPU utilization prediction is implemented described in continuous time as an auto-regressive process of the first order. The technique used the inherent autocorrelation between successive CPU measurements. A specific auto-regression equation for predicting CPU utilization is provided. CPU utilization prediction is used in a computer cluster environment. In an implementation, CPU utilization percentage values are used by a scheduler service to manage workload or the distribution of requests over a vast number of CPUs.

摘要： A group of shared-storage resources are being maintained as replicas by the nodes of a cluster. Each node in the cluster maintains a set of pointers to the members of the group. As membership changes, the set of pointers should be changed accordingly. For various, reasons, the set of pointers of a node are not changed and may point to shared-storage resources that are no longer members of the group and/or not point to shared-storage resources that are members of the group. By recording a history of membership changes in the shared-storage resources, and comparing the recording to what a node thinks the shared resources should be, an incorrect set of pointers can be detected and corrective active undertaken.
