7.1.5: Remote database access with DB2 Universal Database (UDB)

DB2 databases can be installed on the same machine as the WebSphere Application Server software or on a different machine. Installing the database on a different machine has several advantages:

  • Placing the database and application server software on different machines improves their performance because they do not need to compete for system resources.
  • You can independently tune the machines that host the database server and the application server to achieve optimal performance.
  • Many organizations have invested in high-availability solutions for their database servers, reducing the possibility of it being a single point of failure in a system.

All remote database clients use a communications product to support the protocol that is used to access a remote database server. The protocol stack must be installed and configured before a client can communicate with a remote DB2 UDB server. For WebSphere Application Server, the recommended protocol is TCP/IP.

See the WebSphere Application Server installation documentation for your platform for instructions on how to configure a remote DB2 database.
