 | 19-AUG-10 | Everything you ever wanted to know about the Cluster Health Monitor. | Markus Michalewicz | - | The Cluster Health Monitor (CHM) (formerly known as Instantaneous Problem Detector for Clusters, or IPD/OS) is designed to detect and analyze operating system (OS) and cluster resource related degradation and failures in order to bring more explanatory power to many issues that occur in clusters where Oracle Clusterware and Oracle RAC are running such as node eviction. This web seminar will introduce CHM in more detail and explain its usage. |
| 05-AUG-10 | Provisioning Oracle RAC in a Virtualized Environment using Oracle Enterprise Manager | Kai Yu | General | Oracle Enterprise Manager provides an end-to-end solution for automated provisioning, patching, and lifecycle management of virtual infrastructures and Oracle Real Application Clusters (Oracle RAC). Oracle Enterprise Manager provides a central management solution for Oracle RAC in virtualized environments. Learn how Oracle Enterprise Manager allows rapid provisioning of Oracle RAC systems in a virtualized environment by using prebuilt Oracle VM templates and Oracle RAC provisioning features. Authored by a Dell engineer and the Oracle enterprise manager product manager, this session shows the best practices to establish an Oracle VM environment on commodity servers and to configure the guest VMs for deploying Oracle RAC using Enterprise manager VM management pack. It will focus on how to provision and scale up an Oracle RAC system in no more than a few clicks using the enterprise management provisioning pack. The presentations will share the road map for upcoming provisioning, virtualization, and cloud computing features of Oracle Enterprise Manager. |
| 22-JUL-10 | RAC BOOTCAMP: PERFORMANCE MONITORING & TUNING RAC | John Kanagaraj | Performance | In this RAC Bootcamp presentation, we will look at the considerations and procedures for optimizing database and application performance in a RAC environment. Starting with a deeper understanding of some of the background processes, we will progress to RAC related wait events and what they mean. Armed with this information, we will look at RAC specific AWR and Statspack report sections, understand what they mean and how to interpret them. We will also look at best practices and design issues including workload partitioning and management.
Our assumption is that you have an adequate understanding of Oracle RAC in that you have a good understanding of how RAC is setup and managed as well as some of the concepts such as the Interconnect, Cache transfers and RAC specific background processes and their functions. We will not spend time in this paper or in the presentation on the concepts except where warranted. |
| 08-JUL-10 | ASM: advantages and disadvantages | Frits Hoogland | ASM |
https://ouweb.webex.com/ouweb/k2/j.php?ED=138614472&UID=1129614272&RT=MiM0
Oracle is positioning ASM as the resolution for resolving storage and I/O problems. Is this true? Or does ASM have advantages and disadvantages and do you need to make a choice depending on your specific situation? This presentation shows how ASM works, and discusses the basic storage choices, like not using ASM, redunancy levels and using ASMLib. Learn about ASM and its characteristics!

| 24-JUN-10 | Under the Hoods of Cache Fusion, GES, GCS and GRD | Arup Nanda | General |
https://ouweb.webex.com/ouweb/k2/j.php?ED=140262902&UID=1138478717&RT=MiM0
How does cache fusion actually work? What is the role of Global Enqueue Service and how is it different from Global Cache Services? Well, what's the concept of enqueue in case of RAC? Is locking handled differently in RAC compared to single instance? How is the GRD populated, or mainatained, or worse, what is a Global Resource Directory? Learn answers to all these questions explained through live online deomonstrations. Find out different modes of the locks, how locks are downgraded/upgraded, how instance locks are different from row locks and how they are acquired and released, how cache fusion does not always mean network transfer but causes I/O as well, and much more, all shown via live demos. Mastering these important concepts will not only help you in administering a RAC cluster; but hone your troubleshooting and tuning skills as well. |
| 13-MAY-10 | Migrating from an administrator-managed database to a policy-managed database | Markus Michalewicz | Oracle Clusterware |
https://ouweb.webex.com/ouweb/k2/j.php?ED=137521782&UID=1123381847&RT=MiM0
With Oracle Database 11g Release 2 and Oracle Grid Infrastructure a new way of managing Oracle Real Application Clusters (RAC) Databases was introduced: Policy-managed databases. This session will review the motivation for policy-managed databases and the new way (policy-managed) versus the old way (administrator-managed)to manage clustered databases in a grid. Also this session will discuss how to migrate from an administrator-managed database to a policy-managed database (and vice versa).

| 04-MAR-10 | Oracle ASM 11g Release 2 - The Evolution | Alex Gorbachev | ASM |
https://ouweb.webex.com/ouweb/k2/j.php?ED=134103337&UID=1106348167&RT=MiM0
Oracle Automatic Storage Management has proven to be one of the most widely adopted new features in Oracle Database 10g and it has been dramatically improved in the later 11g releases. This presentation will explain what changes are solved by ASM, how these challenges are solved, what barriers there are to ASM adoptions, and how 11g Release 2 addresses these barriers. |
| 18-FEB-10 | Practical Performance Management for Oracle Real Application Clusters | Barb Lundhild | Oracle Clusterware | https://ouweb.webex.com/ouweb/k2/j.php?ED=134300527&UID=1107263257&RT=MiM0
Learn strategies for managing the performance of your Oracle Real Application Clusters database. We will review the common problems that customers have faced and how to resolve them. This session will provide hints and tips for performance problem solving when using a cluster. Join the experts to uncover the best practices to get the best performance from your application. |
| 03-DEC-09 | Why I/O and CPU, not Interconnect Speed, is Critical to RAC Performance | Arup Nanda | Oracle Clusterware | Ever since cache fusion has been made write-write, it has been generally perceived that a very high interconnect speed is vital to the success of RAC performance. This is a myth. Much of the RAC performance depends heavily on the availability of CPU for the key processes as well as the effectiveness of the storage subsystem. This myth often leads to mis-diagnosis of performance issues not yielding any resolution. In this session, attendees will learn how to correctly diagnose the RAC performance issues by understanding the real cause of the interconnect related wait events, especially with respect to CPU and I/O. Finally a real life case study will show how these principles were applied to correctly diagnose an issue. |
| 12-NOV-09 | Oracle Clusterware 11g Release 2 - a first glimpse under the hood - NOTE TIME: 8AM PT | Markus Michalewicz | Oracle Clusterware | One of the major enhancements in Oracle Database 11g Release 2 is the easier management of databases in dynamic and scaleable architectures. Oracle Clusterware 11g Release 2 is the underlying infrastructure that lets any enterprise application benefit from cluster environments. Following this session, you will learn, how new concepts like the server pool based Policy-based management, Grid Plug and Play (GPnP), and the new Grid Naming Service (GNS) enable Oracle Clusterware to support highly flexible grid environments |
| 29-OCT-09 | What is the point of oRACle Checkpoints? | Harald Van Breederode | Performance | This web-seminar explores the circumstances causing the issuance of all the checkpoint types
used by the Oracle RAC database server, and in particular, how checkpoints occurring on one instance may impact other instances. It begins by introducing the key data structures and logic of the Oracle buffer cache including the touch count based LRU algorithm. Redo Log architecture is then investigated, examining the relationship between buffer cache and redo log management thereby demonstrating the importance of correct online redo log sizing. The lesson continues by discussing checkpoint related database parameters and dynamic performance views and concludes by adding practice to theory with live demos on a RAC database.
