The replication of large amounts of data from a database source to a
database target is often prone to failure when the amount of data exceeds
the transaction capacity of the database. In other words, if the amount
of data transfer during initial start-up fills the transaction log before
the database changes are committed, then the transaction does not
complete and the changes are rolled back. For a transaction to be
completed and database changes to be made permanent, the transaction must
be completed in its entirety. A method for initializing data propagation
execution for a large data source according to an embodiment of the
invention uses standard DBMS copy, rename and log clearing/cleaning
utility applications to successfully complete an initial load process so
that all necessary initialization fields are primed. The method steps
create temporary database table names and structures and execute an
initialization/cold start using a single data record to set a
synchronization point marker. Upon validation of the single record
initialization, the replication of the large data table proceeds in a
continue/warm mode from the set synchronization point marker. Executable
instruction steps and computer readable media incorporating the
executable instruction steps are disclosed.
