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. | 02-25-2010 |

| 20110099145 | Synchronizing Changes in a File System Which Are Initiated by a Storage Device and a Host Device - When a storage device initiates a change in its file system, it locally stores it for future update of the file system.

If there are no file system changes pending in the host device, the storage device gets permission from the host device to update the file system with the change and, then, the host device reads the updated file system from the storage device. If there are file system changes pending in the host device, the host device updates a representation of the file system residing in the host device, causes the storage device to make the same changes, and then the storage device initiated change, in the file system. Lastly, the host device receives information from the storage device regarding the changes initiated by the storage device. | 04-28-2011 |

| 20140040194 | METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR SEQUENCING ASYNCHRONOUS MESSAGES IN A DISTRIBUTED AND PARALLEL ENVIRONMENT - System and method of sequencing distributed asynchronous messages. An inbound handler receives an incoming message with a sequence correlation value that identifies a sequence comprising the incoming message, and checks for a sequence status of the sequence. If the sequence status indicates that none of multiple outbound handlers is currently processing a message for the sequence and if the incoming message is the next message to be processed for the sequence, then the incoming message is forwarded to a queue storage and subsequently forwarded to an available outbound handler. If the sequence status indicates that at least one of the outbound handlers is currently processing a message of the sequence, if the queue storage already comprises a message to be processed for the sequence, or if the incoming message is not the next message to be processed for the sequence, then the incoming message is stored in overflow storage. | 02-06-2014 |
| 20140074780 | PREVENTING DATABASE REPLICATION CONFLICTS IN A DISTRIBUTED ENVIRONMENT - A distributed system of data centers is configured to ensure that all data operations involving specific accounts are performed within a given time frame at only one data center. Once a data center has begun accessing data that is associated with an account, all requests to access or manipulate data for that account are redirected to that data center for a period of time. Thus, the data center becomes not only the “owner” of all data associated with the account for that period of time, but also the servicer of all requests associated with the account. The data center then asynchronously replicates changes to the data associated with the account to the other data centers. Since none of the other data centers are permitted to change the data associated with the account, conflicts in the replicated data are minimized. | 03-13-2014 |
| 20140074781 | SYNCHRONIZATION OF SEQUENTIAL ACCESS STORAGE COMPONENTS WITH BACKUP CATALOG - Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance.

| 20160048532 | FILE MANAGEMENT IN THIN PROVISIONING STORAGE ENVIRONMENTS - A computing environment includes a home site and a cache site with nonhomogeneous thin-provisioned storage configurations. A file management system updates files stored at the cache site. Each updated file has an updated file size and a pre-update file size. When a resynchronization is needed between the cache site and the home site, for example due to an extended communication failure, the storage requirement changes for the updated files are calculated and a notification is sent to the home site. The notification identifies the updated files and the storage requirement changes. The home site sends a reply to the cache site. The reply identifies which files are approved for immediate processing. The cache site transfers resynchronization data for the approved files to the home site, and delays transferring resynchronization data for the unapproved files until subsequent replies from the home site indicate that the previously unapproved files are now approved. | 02-18-2016 |

| 20160188690 | DIFFERENTIATED SECONDARY INDEX MAINTENANCE IN LOG STRUCTURED NOSQL DATA STORES - There are provided a system and a computer program product for operating multi-node data stores. The system stores a data table in a first computing node and stores an index table in a second computing node. The index table provides keys used for accessing data in the first computing node and other multi-node data stores. The system performs operations that update or read the data table accessed from the first computing node and the index table accessed from the second computing node. The operations optimizes between latency in updating or reading the data table and the index table and data consistency maintained between data entries in the data table and data entries pointed by indices in the index table. | 06-30-2016 |
