Benefits of using DB2 Multisystem

Benefits of using DB2^® Multisystem include improved query performance, decreased data replication, larger database capacity, and so on.

You can realize the benefits of using DB2 Multisystem in several ways:

• Query performance can be improved by running in parallel (pieces of the query are run simultaneously on different servers)
• Need for data replication decreases because all of the servers can access all of the data
• Much larger database files can be accommodated
• Applications are no longer concerned with the location of remote data
• When growth is needed, you can redistribute the file across more systems, and applications can run unchanged on the new systems

With DB2 Multisystem, you can use the same input/output (I/O) methods (GETs, PUTs, and UPDATEs) or file access methods that you have used in the past. No additional or different I/O methods or file access methods are required.

Your applications do not need to change; whatever connectivity methods you currently use, unless you are using OptiConnect, also work for any distributed files you create. With OptiConnect, you must use the OptiConnect controller descriptions.
