摘要

Replication in distributed environment has become increasingly popular due to its high degree of availability, fault tolerance and enhance the performance of a system. These advantages of replication are important because it enables organizations to provide users with access to current data where and when user needed at anytime or anywhere, even if the users are geographically remote. However, this way of data organization introduces low data consistency among replicas when changes are made during transactions. Therefore, a system to monitor data replication in distributed system environment arises. Read-One-Write-All Monitoring Synchronization Transaction System (ROWA-MSTS) has been developed to solve this problem. By using this system, it helps to monitor the replicated data distribution over multiple sites while maintaining the data consistency.
