If you are interested in learning more about mainframe network management, there is an upcoming webcast on "Proactive problem determination and automation for IBM System z TCP/IP networks".
This is a free webcast sponsored by IBM that will help you learn how to better manage and optimize mainframe network throughput and technologies with IBM Tivoli System z network management solutions, and achieve the highest degree of mainframe network performance. You’ll come away with a better understanding of how IBM Tivoli can help you get the most out of System z networking components such as Enterprise Extender (EE), Open Systems Adapter (OSA) network controllers and TN3270 applications.
