Breaking the Technology Barrier

PCTI's database middleware technology (U.S. PAT: #6,421,688 and other pending patents) has broken a long-standing technological barrier in transaction replication.  This breakthrough enables synchronous parallel transaction replication using multiple stand-alone database servers. It is capable of delivering higher database performance and higher service availability at the same time.  

Databases are the most crucial components in the IT infrastructure, especially where mission-critical transactional applications are involved.  Traditionally, availability is achieved by sacrificing performance; transaction protection is achieved by sacrificing performance and availability. It was impossible to achieve high performance and high availability at the same time.  

PCTI's DB^x™ is the second generation of the ICX-UDS DBScaler parallel synchronous transaction replication engine designed for businesses of all sizes.  PCTI's product suite allows continuous database protection and performance enhancements with zero transaction loss — a capability that substantially exceed competitive products. 
 
How Our Technology Works

PCTI's patented parallel processing technology elevates data replication technologies to a new level: enabling higher performance and higher availability at the same time. It works when transactions are being transferred from the clients before reaching the server. It can dynamically serialize updates that have concurrency conflicts, dynamically load balance the read queries and parallel replicate other updates. This allows building a customized database grid for improved performance and availability simultaneously. This revolutionary technology allows parallel synchronous transaction replication without the usual overheads associated with total transaction serialization and the traditional two-phase-commit protocol with immediate rollback. This technology provides the foundation for building ultra high performance and highly available database service for arbitrarily large datasets.

This middleware can be added-on to an existing IT infrastructure, requiring minimal changes to existing applications and can be applied to all types of database systems including MySQL, Microsoft SQL Server, Oracle, Sybase and DB2. The current product supports Microsoft SQL Server®.
