Hot swapping (frequently inaccurately called hot plugging) is replacing or adding components without stopping or shutting down the system. With the appropriate software installed on the computer, a user can plug and unplug such components without rebooting. Specifically, hot swapping describes inserting and/or removing components without interruption to the system. A well-known example of this hot swap functionality is the Universal Serial Bus (USB) that allows users to add or remove peripheral components such as a mouse, keyboard, printer, or portable hard drive; depending upon the supplier such devices are characterized as hot-swappable or hot-pluggable.

Class dependency graph-based class loading and reloading
Embodiments of a system and method for providing class dependency graph-based class loading and reloading may be used to segregate namespaces in a graph-centric way, and may provide a set of normalized topologies that may be used to efficiently support hot-swapping of programmatic logic such as classes, applets, and beans, among other applications. Embodiments may provide a domain-independent, flexible and robust namespace segregation technique that is based on the dependency between the various classes and not on details like the roles the classes play. The problem of segregating namespaces is formulated as a graph theory problem, and a solution is sought through graph techniques. The graph may be normalized by identifying and grouping interdependent classes and non-interdependent classes in separate groups. A directed dependency relationship of the groups may be determined using the relationships between the member classes of the groups.

Method for replacing a device driver during system operation
A method and system for replacing a device driver during system operation provides for hot-swapping device drivers without shutting down a device driver stack. Particularly useful with file system and file storage devices, the method and system utilize a shell device driver that replaces the physical device driver's entry point interface. The shell device driver has a device driver side interface that calls the physical device driver in response to operating system requests. When an update of the physical device driver is requested, either by an operating system utility or a special upgrade application, the shell device driver receives an update indication. The shell device driver can then finish required tasks, uncouple and unload the existing physical device driver and couple to the new device driver without disrupting the operating system device interface.

Hot unpluggable media storage device
InactiveUS20050021880A1Simple technologyInput/output to record carriersComponent plug-in assemblagesFile systemSoftware engineering
Improved techniques for rendering a peripheral device removable (e.g., unpluggable) are disclosed. According to one aspect of the invention, the peripheral device is rendered removable from a host computer without preparatory user actions. In effect, the peripheral device can be automatically prepared for removal in the event that its user removes (unplugs) it from its host computer. According to another aspect of the invention, the peripheral device includes a data storage device that is mounted to a file system of the other computer when the other computer desires access to the data storage device. Otherwise, the data storage device is normally unmounted so that if the peripheral device were to be removed (e.g., unplugged) no harm or damage to data stored therein would occur. These aspects of the invention can be utilized alone or in combination with one another. The invention is particularly well suited for peripheral devices that are media players which are “hot” unpluggable without detrimental consequences.

Memory data verify operation
A system and technique for detecting data errors in a memory device. More specifically, data errors in a memory device are detected by initiating an internal READ command or verify operation from a set of logic which is internal to the memory system in which the memory devices reside. Rather than relying on a READ command to be issued from an external device, via a host controller, the verify logic initiates verify routine in response to an event such as an operator instruction, hot-plug operation, or a periodic schedule. By implementing the verify operation, the system does not rely on external READ commands to verify data integrity. The verify routine may rely on typical ECC error logging mechanisms and may be used in a RAID memory architecture. Further, the verify routine may be used in conjunction with other error logging and correction logic, as well as scrubbing logic.

Achieving autonomic behavior in an operating system via a hot-swapping mechanism
Systems, especially operating systems, are becoming more complex to the point where maintaining them by humans is becoming nearly impossible. Many corporations have recognized this trend and have begun investing in autonomic technology. Autonomic technology allows a piece of software to monitor, diagnose, and repair itself. This can be used for improved performance, reliability, maintainability, security, etc. Disclosed herein is a mechanism to allow operating systems to hot swap a piece of operating system code, while continuing to offer to the user the service which that code is providing. This can be used, for examples, to increase the performance of an application or to fix a detected security hole live without bringing the machine down. Some autonomic ability will be mandatory in next generation operating system for without it they will collapse under their own complexity. The invention offers a key component of being able to achieve autonomic computing.
