20090216777 | MULTIPHASE TOPOLOGY-WIDE CODE MODIFICATIONS FOR PEER-TO-PEER SYSTEMS - Systems and methods that supply changes on-the-fly and without breaking execution of codes for schema changes in a peer-to-peer environment. The modification component supplies changes to peers or nodes in a topology by initially identifying dependencies (e.g., multiple level) of that can be affected by the schema change, followed by performing the schema change to the codes or stored procedures. Accordingly, dependencies in entire system can be refreshed, wherein multiple levels of dependencies can exist. | 08-27-2009 |
20100106744 | CONFLICT PREVENTION FOR PEER-TO-PEER REPLICATION - Aspects of the subject matter described herein relate to conflict prevention. In aspects, a peer that seeks to modify a data structure first determines whether it is the owner of the data structure. An owner of the data structure has rights to update the data structure. If the peer is not the owner, the peer sends a request to the owner. The owner responds to the request by changing ownership of the data structure to the peer. Once this change is replicated to the peer, the peer is able to update the data structure as desired. | 04-29-2010 |
20100125557 | ORIGINATION BASED CONFLICT DETECTION IN PEER-TO-PEER REPLICATION - Systems and methods that enable conflict detection in a peer-to-peer replication by embedding origination information in data records. A tracing component can track embedded information in form of peer ID and transaction ID, wherein conflicts can be detected by comparing a pre-version (prior to current version) of data on the source node—with—a current version of the data on the destination node. | 05-20-2010 |
20100274768 | DE-DUPLICATION AND COMPLETENESS IN MULTI-LOG BASED REPLICATION - Aspects of the subject matter described herein relate to multi-log based replication. In aspects, database fragments are associated with different logs. Each change to a duplicated database record may be recorded in multiple logs. A history data structure is used to determine when duplication schemas are valid. A duplication schema indicates what database fragments duplicate one or more database records. For a particular time range, the duplication schema history is used to determine whether currently available logs include all changes. If multiple logs include the same change, one log may be selected to provide the change. Non-duplicative changes may be placed into a single data stream usable to update a remote database. | 10-28-2010 |
20110167038 | Dispatching Conflicting Data Changes - A method for distributing one or more conflicting data changes. The method includes extracting data changes from the source site log, and applying the data changes to the destination site. The method then includes identifying one or more constraints for each data change and generating a hash value for each identified constraint. The method then dispatches the data changes into a plurality of streams based on the hash values. The hash values are used to identify conflicting data changes and determine how the data changes should be sent through the plurality of streams such that data changes are applied in parallel in the plurality of streams without violating any causal consistency constraints. The method then includes committing data changes in the plurality of streams to the destination site in a single transaction, creating a consistent transactional view. | 07-07-2011 |
20110251997 | LOGICAL REPLICATION IN CLUSTERED DATABASE SYSTEM WITH ADAPTIVE CLONING - Architecture that addresses an end-to-end solution for logical transactional replication from a shared-nothing clustered database management system, which uses adaptive cloning for high availability. This can be time based using a global logical timestamp. The disclosed architecture, used for refreshing stale clones, does not preserve user transaction boundaries, which is a more complex situation than where the boundaries are preserved. In such a scenario it is probable that for a given data segment no clone of the segment may contain the complete user transaction history, and hence, the history has to be pieced together from the logs of multiple different clones. This is accomplished such that log harvesting is coordinated with the clone state transitions to ensure the correctness of logical replication. | 10-13-2011 |
20120284295 | LIGHTWEIGHT CACHING OF TRANSACTION LOG FOR SEQUENTIAL ACCESS - Searching cached log blocks.

Adjacent sequentially ordered log buffers are double linked to each other. Each log buffer includes a complete range of log blocks from a starting log block ID to an ending log block ID. As part of the first search one or more links are followed, forward and/or backward, to one or more other log buffers. The method may further include determining that the first log block is not found by following one or more links forward and/or backward to one or more other log buffers and as a result, follow one or more covering pointers to one or more log buffers to search for the first log block. | 11-08-2012 |
