Abstract: Some exemplary embodiments of the present disclosure disclose a computer program stored in a computer readable storage medium in which the computer program includes commands for allowing a recovery server to perform the following operations including: acquiring at least one redo log file; reading the at least one redo log file and loading redo log data on a program global area (PGA) memory, in which the redo log data includes a plurality of change vectors (CVs) and data block addresses (DBAs) associated with the plurality of CVs; analyzing the redo log data and generating a plurality of CV groups, in which the plurality of respective CV groups is associated with DBAs and the DBAs associated with the plurality of respective CV groups are different from each other; generating a CV sorting group in which the plurality of CV groups is sorted based on the DBA; acquiring at least one DBA associated with the plurality of CV groups included in the CV sorting group by performing multi block read (MBR) in a persistent

Abstract: Disclosed is a method for improving a database recovery speed using a log data analysis according to a first exemplary embodiment of the present disclosure, including: reading at least one redo log file and loading recovery log data on a storage unit; analyzing the loaded recovery log data and generating a plurality of sub log data groups, the plurality of respective sub log data groups being associated with specific data blocks and the specific data blocks associated with the plurality of respective sub log data groups being different from each other; and generating at least one adjacent log data group based on positional information of the specific data blocks associated with the plurality of respective sub log data groups, each of the at least one adjacent log data group including at least one sub log data group.
