Presentation Title

Everything a DBA Needs to Know about TCP/IP Networks


Databases do not run in a vacuum. Clients and application servers connect to the database, which connects to storage systems and to each other - communicating through (mostly) TCP/IP networks. Quirks at the network level have a profound effect on the availability and performance of your database.

Can you diagnose those problems, and do you know for sure when the problem occurs? What do you do when your network admin will not listen?

This session explains the underlying principles of network performance, how to use network diagnostics tools to approach database problems, and dives into the fine details of the SQLNET protocol. Learn from an Oracle ACE how to diagnose problems faster and communicate with the network admin more effectively.
