REPLICATING DATA CHANGES USING MULTIPLE STORAGE DEVICES AND TRACKING RECORDS OF PENDING DATA CHANGES STORED ON THE STORAGE DEVICES

Methods, computer program products, and/or systems are provided that perform the following operations: generating log files while performing data changes of a source database system table; storing the log files on a first memory device having a first access time; archiving a part of the log files from the first memory device on a second memory device having a second access time, the second access time being higher than the first access time; tracking a second number of pending data changes, the pending data changes being data changes of the records of data change of log files archived on the second memory device which are not yet replicated in a target database system table; selecting a type of data replication from a first type of data replication and a second type of data replication based on the second number; and replicating the data changes in the target database system table.
