摘要： A method repairs a table. A replication environment has a first replicate comprising a source table on a source server and a target table on a target server. The source server transmits replication data from the source server with repair data from the source server to the target table in accordance with a commit order of the replication data and the repair data. The target server applies the repair data and the replication data to the target table based on the commit order.
摘要翻译：一种修复表的方法。复制环境具有包含源服务器上的源表和目标服务器上的目标表的第一复制。源服务器根据复制数据和修复数据的提交顺序，从源服务器将具有修复数据的复制数据从源服务器传送到目标表。目标服务器根据提交顺序将修复数据和复制数据应用于目标表。

摘要： A method and system for performing at least one transaction on at least one column of a table in a database system is disclosed. The method includes determining whether a first transaction of the at least one transaction fulfills all of at least one criteria. The method further includes ensuring that the at least one column is in a shared numeric lock if the first transaction fulfills all of the at least one criteria, wherein the shared numeric lock is a lock that allows at least a second transaction fulfilling all of the at least one criteria to access the same column concurrently with the first transaction without releasing the shared numeric lock between transactions, and wherein the shared numeric lock is released only after all of the transactions fulfilling all of the criteria have completed processing. The method further includes processing the first transaction.

The method and system include determining whether a first transaction of the at least one transaction fulfills all of the criteria and ensuring that the at least one column is in a shared numeric lock if the first transaction fulfills the at least one criteria. The shared numeric lock allows at least a second transaction fulfilling the at least one criteria to be processed concurrently with the first transaction without releasing the shared numeric lock. The method and system also include processing the first transaction. Thus, the method and system allow multiple transactions to be processed concurrently.

摘要： Techniques are provided for resynchronizing instances of a replicated table. In one embodiment, a database server is provided as a member of a plurality of communicatively coupled database servers. Each database server is configured to support a replicating mode of operation and a non-replicating mode of operation. The instances of the replicated table are resynchronized responsive to a user request, without stopping any of the plurality of database servers and without requiring any of the plurality of database servers to operate in the non-replicating mode of operation.
摘要翻译：提供技术用于重新同步复制表的实例。在一个实施例中，数据库服务器被提供为多个通信耦合的数据库服务器的成员。每个数据库服务器被配置为支持复制操作模式和非复制操作模式。复制表的实例响应于用户请求重新同步，而不停止多个数据库服务器中的任何一个，并且不要求多个数据库服务器中的任何一个以非复制操作模式操作。
