20090327519 | ADDING INDIVIDUAL DATABASE FAILOVER/SWITCHOVER TO AN EXISTING STORAGE COMPONENT WITH LIMITED IMPACT - High availability architecture that employs a mid-tier proxy server to route client communications to active data store instances in response to failover and switchover. The proxy server includes an active manager client that interfaces to an active manager in each of the backend servers. State information and configuration information are maintained separately and according to semantics consistent with needs of corresponding data, the configuration information changing less frequently and more available, the state information changing more frequently and less available. The active manager indicates to the proxy server which of the data storage instances is the currently the active instance. In the event that the currently active instance is inactive, the proxy server selects a different backend server that currently hosts the active data store instance. Client communications are then routed to the different backend server with minimal or no interruption to the client. | 12-31-2009 |
20100228827 | STORAGE MODEL FOR MAINTAINING STRUCTURED DOCUMENT FIDELITY - Architecture that introduces storage of an extra (skeleton) property of a document as well as default document properties on a server. In a specific messaging implementation, a MIME skeleton property is stamped on an arriving MIME messages. An incoming MIME message is shredded and all content that is currently saved to MAPI properties continues to be saved. The remaining message content that is not saved to the MAPI properties is stored in the skeleton property. The skeleton property includes all body part headers and any body part content that was not saved as a property on the item by the server. On retrieval of this message by a MIME client, the MIME message is regenerated in full fidelity by using the default set of properties in combination with the skeleton (or extra) property and the stored body content. | 09-09-2010 |
20110185136 | MOVING LARGE DYNAMIC DATASETS VIA INCREMENTAL CHANGE SYNCHRONIZATION - Incremental change synchronization for moving large data sets may be provided. Source data to be moved may be identified and a snapshot of the data may be created. The data may be moved to a new datastore and a second snapshot may be created. The snapshots may be compared to identify any data elements that have been modified and the modified elements may be copied to the new datastore. | 07-28-2011 |
20120143894 | Acquisition of Item Counts from Hosted Web Services - A web Application Programming Interface (API) server receives a statistics request from a client. The statistics request is a request to invoke an item counting method defined in an API provided by the web API server. The statistics request specifies a keyword string and multiple target data repositories. As a response to the statistics request, the web API server sends a statistics response to the client. The statistics response specifies an item count that indicates how many relevant items are in the target data repositories. Each of the relevant items is associated with at least one keyword in the keyword string. | 06-07-2012 |
20120150917 | USAGE-OPTIMIZED TABLES - Systems and methods are disclosed for employing usage-optimized tables with a computer database system. In one embodiment, the database system stores create, update, and delete database operations in the usage-optimized table. The create, update, and delete database operations remain in the usage-optimized table until a flush condition is reached. When the flush condition is reached, the create, update, and delete operations are transferred to their corresponding real tables. In embodiments, the read operation does not flush the contents of the usage-optimized table to the real table. In such embodiments, the database system modifies read operations to account for data resident on the usage-optimized tables. | 06-14-2012 |

20130086381 | MULTI-SERVER AUTHENTICATION TOKEN DATA EXCHANGE - A client is authenticated by a server receiving an initial request from the client at the beginning of a session. The server receiving the initial request generates an authentication token and returns the authentication token to the client in response to the client being authenticated. The user's credentials used to authenticate the client are stored in the authentication token along with other information. After receiving the authentication token from the server that generated the authentication token, the client passes the authentication token with each of the future requests to the pool of servers. Using the client to pass the transferrable authentication token, the servers share the user's identity/credentials in a decentralized manner. Any server from the shared pool of servers that receives a subsequent client request is able to decrypt the token and re-authenticate the user without having to prompt the client for authentication credentials again. | 04-04-2013 |
20130191465 | FACILITATING MESSAGE SERVICES USING MULTI-ROLE SYSTEMS - Systems, methods, and software are provided for facilitating a message service. A multi-role system is identified based on where an active message database associated with a user identity resides. Service communications generated by a messaging client associated with the user identity are directed from an entry system to the multi-role system for handling in the multi-role system by a messaging server and a content server to provide the message service. | 07-25-2013 |
20140133485 | DATA PACKET ROUTING - Among other things, one or more techniques and/or system are provided for routing a data packet. Because the data packet may correspond to a source device having an address on a first network that may be similar to an address of a second device on a second network, the data packet may be translated to create a transformed data packet that may be distinguishable from data packets of the second device. For example, the data packet may be translated from a first address format, such as IPv4, to a second address format, such as IPv6, to create a transformed data packet. The transformed data packet may comprise a prefix that may distinctly identify the source device during routing. In this way, the transformed data packet may be identifiable as corresponding to the source device during routing through a network to a destination device. | 05-15-2014 |
