摘要： An apparatus, system, and method are disclosed for managing storage space allocation. The apparatus includes a recognizing module, a reserving module, and a managing module. The recognizing module recognizes a trigger event at a client of the data storage system. The reserving module reserves logical units of space for data storage. The management module manages the logical units of space at the client. Such an arrangement provides for distributed management of storage space allocation within a storage area network (SAN). Facilitating client management of the logical units of space in this manner may reduce the number of required metadata transactions between the client and a metadata server and may increase performance of the SAN file system. Reducing metadata transactions effectively lowers network overhead, while increasing data throughput.

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： A method and system for distributing tasks from an external application among concurrent database application server instances in a database system for optimum load balancing, based on consensus among the instances. Each application instance identifies a task partition ownership by those in a membership group based on a time window and generates a new membership group and partition ownership based on the current partition ownership. The instance makes the new membership group and partition ownership known to other members by recoding them in the membership table and partition map. Each participation by an instance in the membership group is identified by a random number. The new membership group and partition ownership are generated and adjusted based on an average partition allocation to achieve consensus among the instances.
