Abstract: 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 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.

Abstract: A method, system and article of manufacture implementing the 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.
