A method for monitoring file system requests made by an application program, storing changes made to a first copy of a selected file by the application program into a first file and synchronizing the changes made to the selected file with a second copy of the selected file. The monitoring and storing process is application independent in that it is utilized by the operating system for all file system requests made by any application program. The monitoring and storing process is repeated each time a file system request is made by the application program to track changes made to the selected file. At the time of synchronization, if the application program is no longer modifying the selected file and the selected file is closed, all entries in the first file are applied to the second copy of the selected file. As a result, synchronization of both copies of the selected files is achieved.

A system and method describing a compatibility server for rehosting database applications written for a specific vendor's database on the database of a second vendor, without the need of rewriting the application to take into account differences in the application programming interfaces between the first vendor's database and the second vendor's database. Requests for access to the database are translated from one format to another at execution time. The server is also capable of translating error messages, data types and data formatting from the format used by the second database to that expected when making requests to the first database. Stored procedures defined in the first database are migrated to the second database as text blocks, and are translated at execution time into a high level programming language, compiled and executed against the second database. All information necessary for the mapping of schema, data, data types, error and status messages and data formatting, as well as information necessary to execute stored procedures, is stored in a plurality of metadata tables in the second database, which are created during a migration phase prior to executing the application.

A database may facilitate zero-downtime upgrades by concurrently maintaining multiple editions of database objects for use by both pre-upgrade and post-upgrade clients of a database application. Operations performed within the database are associated with an edition based on, for example, an initiating client or transaction. When an operation references an object or data, the database automatically performs the operation using the object or data associated with the edition with which the operation is itself associated. The database may determine the associated edition without explicit identification of the associated edition in a query or in code. Thus, no client or stored procedure code changes are necessary to reflect a new edition added during an update. Data changes in one edition may be automatically and immediately propagated to the other edition through the use of cross-edition triggers, thereby allowing both pre-upgrade and post-upgrade clients to remain fully functional throughout an upgrade.

An application independent method for monitoring file system requests made by any application program, storing changes made to a first copy of a selected file by the application program into a first file and synchronizing the selected file, whether the file is open or closed, with a second copy of the selected file. The monitoring and storing process is repeated each time a file system request to write into the selected file is made by the application program to track changes made to the selected file. At the time of synchronization, if the selected file is closed, all the changes that are stored in the first file are applied to a second copy of the selected file. If, however, the selected file is open, a portion of the changes are selected pursuant to a predetermined time period and applied to a second copy of the selected file. As a result, both copies of the selected files are identical, thereby synchronizing them. For open files, both copies of the selected file are identical up to the predetermined time period.

A USB device enumeration process implemented in a USB device is described. The USB device first detects a type of the operating system (OS) of the USB host connected to the device, and performs device enumeration using a process selected from multiple stored processes based on the detected host OS type. To detect the host OS type, the USB device first presents itself to the host as a USB MSD or HID, performs device enumeration to collect OS behavior factors from the host, and determines the OS type from the OS behavior factors. Thereafter, the USB device performs actual device enumeration by presenting itself as the USB device it actually is, using an enumeration process specific to the detected host OS type. The multiple stored enumeration processes are customer configurable. Further, a method is provided to stop an enumeration process when the host is in a BIOS stage.

The invention is applied to the technical field of flash memory storage, and provides a flash memory and a method and a system for automatically separating cold and hot data based on the same. The method comprises the steps that a hot degree identifier for showing the access frequency of data is added for each record in a logic physical address mapping table of the flash memory; and when the flash memory processes data, the hot degree identifiers in the logic physical address mapping table are updated according to the preset hot levels, and different hot levels correspond to different hot degree identifiers. According to the flash memory and the method and the system for automatically separating cold and hot data based on the same, the cold and hot degrees of data are processed directly in the logic physical address mapping table of the flash memory, and just modifying an FTL (Flash Translation Layer) algorithm can separate cold and hot data without using additional software and cache. Therefore, the flash memory and the method and the system for automatically separating cold and hot data can automatically realize the separation and storage according to the access frequency during the storage of data in the flash memory instead of using additional cold and hot data judgment algorithm and cache.
