Oracle Clusterware for DBA’s and Sysadmins with Roland Knapp, 28-29 April, Lysaker April 27, 2010

This new seminar describes advanced techniques for managing Oracle Clusterware and its processes including configuration, diagnosibility and best practices.

The first session of the seminar describes the general function and the different layers within Oracle Clusterware like Cluster Synchronisation Services and Cluster Ready Services.
The second session will focus on the Oracle Clusterware processes, its integration with the operating system and will show which process is responsible for what. We discuss the OPROCD behavior as well as the Oracle Clusterware fencing method.
The third session investigates the difference between CSS and CRS and how they interact. Furthermore, we will address the nodeapps resources, what their functions are and how to change their default values.
The fourth session describes the best practice on Voting Disk and OCR configuration. It will discuss the use of Voting Disks in extended cluster configuration.
The fifth session investigates the network and disk timeout settings within Oracle Clusterware, their tunables and challenges. We address the network/switch redundancy topic.
The sixth session will describe all RACG executeables, the VIP and USERVIP integration as well as how this fits together with ONS and FAN.
The seventh session will focus on the vendor cluster integration with Oracle Clusterware.
In session eight we will discuss and show how simple it is to protect your own application using Oracle Clusterware. There will be a practical example shown on a real installation.
Session nine will focus on the troubleshooting, trace file location and debugging techniques for Oracle Clusterware. We will learn how to use crsctl and its modules to debug and trace Oracle Clusterware issues, and which information is important in order to open Service Requests with Oracle Support.
