Abstract:
1. A method for data disaster tolerance preprocessing, comprising: setting a first database in a first Service Control Point (SCP), wherein the first database is used to perform disaster tolerance backup for a second database in a second SCP; after the step of setting the first database in the first SCP, the method further comprising: database-synchronizing the first database of the first SCP with the second database of the second SCP through an oracle advanced replication, wherein the step of database-synchronizing the first database of the first SCP with the second database of the second SCP through the oracle advanced replication comprises: the second database creating a materialized view log for a local data table needing disaster tolerance backup; the first database creating a database link, wherein a destination database of the database link is the second database of the second SCP; the first database creating a materialized view according to the database link, wherein the materialized view corresponds to the materialized view log one to one; and the materialized view regularly reading update information in the corresponding materialized view log and performing data synchronization according to the update information.
