摘要:
A method for implementing virtual disk reservations on a storage medium for multiple distributed applications. The method includes initializing a plurality of virtual disks, wherein each of the virtual disks is instantiated on a physical storage medium. A reservation status is determined for each of the virtual disks and a first distributed application that uses at least one virtual disk is executed. Upon an update of the reservation status for the at least one virtual disk by the first distributed application, a notification indicator is set to notify a second distributed application of the update. The update is subsequently recognized and the notification indicator is cleared in order to continue I/O for the first distributed application and the second distributed application.

Rechargeable packaging for dispensing fluid substances having a bell-shaped case (1) through which passes a manual plunger (2), which has an orifice (3) providing a passage for a dispensing nozzle (30) and the open base of which is closed by a removable base (5). The interior of the case housing has a replaceable cartridge (4) comprising an inverted pot shaped container (6) with a bottom (7) that is free to move axially and the top face of which has an orifice (15) communicating with a dispensing nozzle (30) via a dispensing device (16, 32) actuated by the plunger. The container and the case have cooperating means (10, 11) for locating the cartridge in the case, the cartridge being secured in the case by its base (5).

A fastener ring for fastening a dispenser member, such as a pump or a valve, on a neck of a reservoir, the ring including a reception mechanism suitable for receiving the dispenser member, and a substantially-cylindrical attachment skirt for coming into engagement around the neck of the reservoir. The skirt defining an inner wall that defines a top first inner wall section for coming into engagement with the neck, and a bottom second inner wall section for extending out of contact with the neck. The attachment skirt includes an orientation tab that interrupts the bottom second inner wall section and that projects radially inwards relative to the second section.

Techniques for updating a cached version of data in a computer system upon a change of the data as stored in a shared storage system networked to the computer system are described. In accordance with such techniques, a notification from the shared storage system is received at the computer system upon attempting to access the shared storage system. The computer system then determines that the notification occurred due to an unregistering of the computer system's access to the shared storage system by a second computer system that has updated the data stored in the shared storage system. As such, the computer system re-registers its access to the shared storage system and updates the cached version of the data with the data in the shared storage system that was updated by the second computer system.
