Abstract
A distributed transaction system includes a plurality of log groups each having a unique identifier assigned thereto, a data storage device storing data and a log storage device storing a log of the data. A table is provided in each of the log groups and has registered therein information about a database management device having the management right of each of the log groups. Wherein in response to the management right of the global representative log group moving to another database management device during an in-doubt state period of the two-phase commit, the table is rewritten to reflect moving of the management right of the global representative log group.
