1. A computer program stored a non-transitory computer readable storage medium, wherein if the computer program is executed by one or more processors the computer program performs operations for Change Data Capture (CDC) by one or more processors, and the operations comprises:
extracting a change data from at least one redo log of an online redo log and an archive redo log;
analyzing at least one information of a resource utilization rate information and a remain log information of a source database server; and
determining to process the change data in one mode of a first mode saving the change data as a CDC file and a second mode recording the change data in a memory, based on at least one of the remain log information and the resource utilization rate information.
