| 20100030730 | System, Method, and Computer Program Product for Determining SQL Replication Process - A system, method, and computer program product are provided for replicating a table in a source database to a target database. In accordance with an embodiment of the present invention, a subscription to the table is defined and a query is executed on the source database. The query is then normalized, and it is determined whether the query would cause semantically appropriate changes to the target database. If so, the normalized query is sent to the target database for execution, in accordance with an additional embodiment of the present invention. | 02-04-2010 |

An embodiment includes providing a scalable distribution of in-memory database (IMDB) system nodes organized as one or more data fabrics. Further included is providing a plurality of data granularity types for storing data within the one or more data fabrics. Database executions are managed via the one or more data fabrics for a plurality of applications compatible with at least one data granularity type. | 06-21-2012 |
| 20120158805 | NON-DISRUPTIVE DATA MOVEMENT AND NODE REBALANCING IN EXTREME OLTP ENVIRONMENTS - Systems and methods for non-disruptive cache startup, shutdown, data partition movement, and node rebalancing for a data fabric within a data grid in a database environment. The data grid is a clustered in-memory database (IMDB) cache comprising one or more data fabrics including multiple IMDB cache nodes. The method takes a time tag and moves data from source to destination nodes while allowing updates to data on the source nodes. The method propagates updates occurring after the time tag to destination nodes from source nodes and switches applications and ownership to the destination nodes. Another method slices data for a partitioned fabric and stores slices on nodes. Another method starts a data fabric by moving data from a grid backend to the nodes. In an embodiment, another method rebalances nodes in a non-disruptive manner. When a fabric is shutdown, the method saves data from the nodes to the grid backend. | 06-21-2012 |
