The invention provides a system and method for file synchronization. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to receive a file from a server; store the file as a cached file in a cache; determine if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database.

System and method for the synchronization of a file in a cache

The present invention provides a system and method for file synchronization. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to receive a file from a server; store the file as a cached file in a cache; determine if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database.

The present invention provides a system and method for bi-directional synchronization of a cache. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to receive a database asset from a database; store the database asset as a cached file in a cache; determine if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database. The software program can poll a cached file to determine if the cached file has changed. Thus, bi-directional synchronization can occur.

The present invention provides a system and method of synchronizing a cache that substantially eliminates or reduces disadvantages associated with previously developed systems and methods of synchronizing caches. More particularly, embodiments of the present invention provide a system and method for bi-directional synchronization of a cache. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to run in user space and perform steps comprising: receiving a database asset from a database; storing the database asset as a cached file in a cache; determining if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database. In one embodiment of the present invention, the software program can determine if the cached file has been modified through automatic notification from a file management system. Alternatively, the software program can poll a cached file to determine if the cached file has changed. In another embodiment of the present invention, the software program can be further executable to perform the step of prompting an operating system to open the cached file in an application associated with the cached file's file type. In yet another embodiment of the present invention, the software program can be further executable to receive notifications from a database of when contention for a database asset occurs. Thus, bi-directional synchronization can occur.

A method and system for publishing network content is provided. Using an administrator interface, changes to content are made in a staging area. The staging area allows access to the remainder of the network for verifying links. Content is then published to a plurality of production areas in response to a single command.

Embodiments disclosed herein provide a cache management system comprising a cache and a cache manager that can poll cached assets at different frequencies based on their relative activity status and independent of other applications. In one embodiment, the cache manager may maintain one or more lists, each corresponding to a polling layer associated with a particular polling schedule or frequency. Cached assets may be added to or removed from a list or they may be promoted or demoted to a different list, thereby changing their polling frequency. By polling less active files at a lower frequency than more active files, significant system resources can be saved, thereby increasing overall system speed and performance. Additionally, because a cache manager according to embodiments disclosed herein does not require detailed contextual information about the files that it is managing, such a cache manager can be easily implemented with any cache.

Cache management system

Cache management system with application-independent polling

Embodiments of the present invention provide a method and computer program product for bi-directional synchronization of a cache. One embodiment of the method of this invention includes: receiving a database asset from a database; storing the database asset as a cached file in a cache; notifying an operating system to open the cached file using a local application associated with a file type for the cached file; opening the cached file with the local application associated with the type for the cached file; determining if the cached file has been modified; and if the cached file has been modified, communicating the cached file directly to the database. One embodiment of the computer program product of this invention includes program instructions adapted to perform similar steps.

The present invention provides a system and method for optimizing a cache that substantially eliminates reduces the disadvantages of previously developed cache management systems. More particularly, embodiments of the present invention provide a system of optimizing a cache by polling cached assets with a frequency dependent of the relative activity of a cached asset. An embodiment of the method of the system includes the steps of: (i) polling a cached asset according to a first schedule to determine if the cached asset has been active within a first predefined period of time; (ii) if the cached asset has not been active, polling the cached asset according to a second schedule to determine if the cached asset has been inactive for at least a second predefined period of time; (iii) demoting the cached asset to less active status; and (iv) if the cached asset has been inactive for at least within the second predefined period of time, demoting the cached asset to inactive status. In one embodiment of the present invention, if the cached asset has been active within the second predefined period of time, the cached asset can again be polled according to the first frequency. The frequency with which the cached asset can be polled according to the first and second schedule can be a matter of optimization. Polling according to the first schedule can occur at a greater frequency than polling according to the second schedule. Thus, more active assets can be polled more often than less active assets.

Method and system for optimizing resources

A network and method of providing near 100% availability of services is provided. According to one feature, redirectors are implemented to direct network traffic to any of two or more application processors providing the same service. The redirectors are provided in data paths at network access points and at data centers with the application processors. The redirectors re-route traffic to other application processors when one processor is unavailable and load balance between available processors. To load balance, the redirectors collect various network management statistics from the processors to determine the most responsive processor for receiving traffic. The various network management statistics are shared among the redirectors for efficient load balancing.

Embodiments of the present invention provide a system and method for bi-directional synchronization of a cache. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to run in user space and perform steps that can include receiving a database asset from a database; storing the database asset as a cached file in a cache; determining if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database. In one embodiment of the present invention, the software program can determine if the cached file has been modified through automatic notification from a file management system. Alternatively, the software program can poll a cached file to determine if the cached file has changed.
