  • Patent number: 8768905
    Abstract: An indication of refusal of a lock request is received with a first operation identifier for a resource that is already locked with a lock associated with a second operation identifier from an agent that controls the resource, wherein the agent returns a value that determines how long the lock request is to stay on the queue. The lock request is placed in a queue with a lock queue timeout period based on the value from the agent. The lock request is reissued if the lock associated with the second operation identifier has been released and the lock request reaches a position of the queue from which the lock request is processed within the lock queue timeout period. The lock request is re-queued if the reissued lock request is not granted based on how many times the lock request has been previously placed in the queue.

  • Patent number: 8671132
    Abstract: A policy-based data management system, method, and apparatus are disclosed. The system, method, and apparatus are configured to operate over a distributed storage system such as a storage area network (SAN). Files to be stored on the network are each assigned a service class and a storage pool based on the application of policies to file attributes such as file name, type, user, etc. The service class and storage pool designations are stored as metadata. Files may be retrieved using the metadata to identify the storage pool where the file is stored, and the service class listed within the metadata may be used to control the manner in which the file is handled. A metadata server may be utilized to provide the appropriate service class of files in response to requests from remote clients that may be of different computing platforms.

  • Patent number: 8161018
    Abstract: Under control of a first agent, a resource controlled by a second agent is locked with a first operation identifier. Under control of the second agent: a request is received to lock the resource controlled by the second agent with a second operation identifier for a client request for a client application, wherein the resource is already locked with the first operation identifier; it is determined whether the first operation identifier and the second operation identifier are determined to be a same identifier; if it is determined that the first operation identifier and the second operation identifier are the same identifier, the request is responded to with an indication that the resource is locked with the same operation identifier; and, if it is determined that the first operation identifier and the second operation identifier are not the same identifier, the lock request is denied.

  • Patent number: 4561661
    Abstract: The soccer training device for head and foot consists of three major parts, i.e. a base support structure, a fiberglass rod, and a ball. The base support structure is designed similarly to parasol stands; however, it possesses a mechanism for continuous height adjustment of the ball and the fiberglass rod. To this mechanism the rod is attached by means of a swing element.At the tip of the fiberglass rod, the ball is attached to a revolving bearing. The fiberglass rod can have inclinations of approximately 0.degree. to 30.degree.. The fiberglass rod and the swing element serve the purpose of storing potential energy for the return flight of the ball.The ball is set into motion by the head or the foot of a player, and swings back and forth in an arc section of circular radius.
