20100268815 | LIGHTWEIGHT DIRECTORY ACCESS PROTOCOL (LDAP) COLLISION DETECTION MECHANISM AND METHOD - A LDAP collision detection mechanism and a method are described herein that allow a LDAP client to detect and avoid an update operation collision on an entry within a LDAP directory. The method includes the steps of: (a) reading data from the entry in the directory; (b) processing the retrieved data; (c) sending a request to modify the data in the entry in the directory, wherein the client is assured that the requested modification will not be performed by the directory if another client had previously performed a modification on the data within the entry that was originally read by the client. There are several different embodiments of the LDAP collision detection mechanism and the method described herein. | 10-21-2010 |
20100281054 | METHOD AND APPARATUS FOR HANDLING ACCESS TO DATA - Method, apparatus and computer programs for handling access to data distributed along a plurality of databases. A first message comprising a first identifier is received in a server interfacing messages before said plurality of databases, a second identifier usable for sending a message to the database storing data in relationship with the received first identifier is obtained, and a subsequent second message comprising the first identifier is sent to said database. For obtaining the second identifier, the server sends the second message comprising the first identifier to said plurality of databases, and receives a reply from a database among said plurality that stores data in relationship with the first identifier comprising an identifier of said database usable as said second identifier. The invention allows a simplified configuration when a data storage system is split into a plurality of separate databases. | 11-04-2010 |
20130185329 | DISTRIBUTED DATABASE - According to a first aspect of the present invention there is provided a method of operating a distributed database comprising a plurality of database nodes. The method comprises, at a first database node of the plurality of database nodes, receiving a request to manipulate data from a client (B1), determining if the data is stored or is intended to be stored at the first database node and, if the data is not stored or is not intended to be stored at the first database node, forwarding the request towards a second database node of the plurality of database nodes (B2) and, prior to receiving a final response from the second database node, sending an early response to the client indicating that the data manipulation has been successful (B3). | 07-18-2013 |
20130311424 | DISTRIBUTED DATABASE - A method of operating a database node of a distributed database is provided. The distributed database includes a plurality of database nodes each storing a set of data. A latency that occurs when the database node contacts a further database node in order to respond to one or more data requests that relate to a subset of data that is one of stored and intended to stored at the further database node is measured. An average latency value for communicating with each of the database nodes in the distributed database is calculated. Notifications reporting the average latency values to data distribution optimization functions in the distributed database are sent. A latency measure is reported to a further node of the distributed database. | 11-21-2013 |
