Abstract: A distributed transaction management device records a transaction settlement result log indicating a settlement result of a transaction in the distributed transaction system. When the distributed transaction management device receives a rollback processing completion notification from any one of multiple resource management units participating in the transaction, the distributed transaction management device deletes the transaction settlement result log of the rollback.
