High availability (HA) protection is provided for an executing virtual machine. A standby server provides a disk buffer that stores disk writes associated with a virtual machine executing on an active server. At a checkpoint in the HA process, the active server suspends the virtual machine; the standby server creates a checkpoint barrier at the last disk write received in the disk buffer; and the active server copies dirty memory pages to a buffer. After the completion of these steps, the active server resumes execution of the virtual machine; the buffered dirty memory pages are sent to and stored by the standby server. Then, the standby server flushes the disk writes up to the checkpoint barrier into disk storage and writes newly received disk writes into the disk buffer after the checkpoint barrier.

A first embodiment of this invention is a cleaning apparatus for a commercial conveyor belt that is mounted on a conveyor table. The cleaning apparatus is a housing that includes a spraying tube for dispensing a cleaning solution and a novel wiping device. The wiping device is constructed to apply a disposable towel, such as a paper towel, to the conveyor belt to remove the solvent including any contaminants while the conveyor belt is in motion. The used disposable towels are deposited into a waste container thereby requiring very little cleaning maintenance. By a second embodiment the spraying tube is eliminated and the disposable paper towels include a solvent (wet wipes) for removing the contaminants. The cleaning apparatus is preferably mounted on the underside of the conveyor belt next to a crumb tray so that the cashier can easily operate the cleaning apparatus.

A shimless aligner for insertion between a machine foot and base to align the foot relative to the base, which foot and base are secured together by a hold-down bolt extending between the foot and base. The aligner includes, a top plate having a slanted bottom surface, a taper wedge having a slanted top surface slidably engaging the slanted bottom surface of the top plate and further having a vertical alignment rod extending substantially laterally, a bottom plate below the taper wedge, and a back plate attached substantially perpendicularly at one end of the bottom plate. For receiving the hold-down bolt, the top and bottom plates have a corresponding hole, while the taper wedge has a slot. Said back plate has a hole for the vertical alignment rod to slidably engage the hole thereby preventing rotation of the taper wedge during vertical alignment operations and preserving bent foot corrections.

In response to receiving the indication of the failover condition, the server cluster may perform failover, including attaching the one or more data storage devices to a backup virtual machine associated with the one or more data storage devices, so that a second database program executing at the backup virtual machine is able to communicate with the one or more data storage devices, where the backup virtual machine is already executing in the server cluster, and associating the hostname with the backup virtual machine.

A method of repairing a thermal barrier coating (16) on a component (10) designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method more particularly involves repairing a thermal barrier coating (16) on a component (10) that has suffered localized spallation (20) of the thermal barrier coating (16). After cleaning the surface area (22) of the component (10) exposed by the localized spallation (20), a ceramic paste (24) comprising a ceramic powder in a binder is applied to the surface area (22) of the component (10). The binder is then reacted to yield a ceramic-containing repair coating (26) that covers the surface area of the component and comprises the ceramic powder in a matrix of a material formed when the binder was reacted. The binder is preferably a ceramic precursor material that can be converted immediately to a ceramic or allowed to thermally decompose over time to form a ceramic, such that the repair coating (26) has a ceramic matrix. The repair method can be performed while the component (10) remains installed, e.g., in a gas turbine engine. Immediately after the reaction step, the gas turbine engine can resume operation during which the binder is further reacted / converted and the strength of the repair coating increases.
