Patent ID: 7478112

Claim:
A method for initializing data propagation execution for a large data source, comprising: a) providing a source database including an original source database table, with the original source database including a large quantity of data and having a table structure and an original source table name, and providing a target database including an original target database table, with the original target database table including t-he a large quantity of data and having a table structure and an original target table name; b) creating a temporary source database table having data and a table structure identical to the data and the table structure of the original source database table and a name different than the original source table name, in the source database, and creating a temporary target database table having data and a table structure identical to the data and the table structure of the original target database table and a name different than the original target table name, in the target database, c) creating an empty source table having the structure of the original source database table in the source database and naming said empty source table the original source table name, and creating an empty target table having the structure of the original target database table in the target database and naming said empty target table the original target table name; d) moving a single record, from the temporary source database table to the empty source table, which is now a single record source table; e) starting a cold-start/initialization replication of the single record, from the single record source table to the empty target table, which is now a single record target table; f) stopping said replication after a complete replication cycle of the single record, to set a synchronization point marker; g) validating said replication of the single data record; and h) renaming the temporary source database table to the original source table name, and renaming the temporary target database table to the original target table name.
