What we are looking at during this videocast is how to troubleshoot the connectivity issues that can be caused by VIP’s in Oracle RAC environment and how to diagnose cryptic Oracle error messages using SQL*Net tracing facility on the client side.
Oracle’s post-upgrade network ACL setup documentation is much more confusing than it needs to be, at least for simple minds like me. A colleague stepped forward with a simple set of commands for a basic setup that even the tired and stressed can understand. I’ll share that here, with some basic explanation.
The topic for this meetup is quite exciting – Oracle Exadata and everything about it. David Centellas, Senior Database Consultant from Oracle will do technical presentation on Exadata and, after the break, we will have a open forum discussion where two Oracle’s Enterprise Architects, Tim Rubin and Chris Jones, will answer our questions and share thir real-world experience.
Using OLE DB to get SQL Server to connect to Oracle servers can be done quite easily, but there are a few little tricks you should know to make it go smoothly. Once it’s working it seems to work quite well. I hope this blog post will save you a few headaches.
Recently, I tested a switchover on Oracle 11g SE1. As you know, Oracle Database Standard Edition One—as well as Standard Edition—does not have the Data Guard feature. Therefore, I had to do everything manually. The whole process took less than 15 minutes. This includes less than five minutes of full downtime to restart the database in READ-ONLY mode, and less than 10 minutes of READ-ONLY downtime. Here’s what I had.
Welcome, readers! It’s time for another update to our series of posts on installing Oracle on Ubuntu Linux. In this edition, we’ll be installing Oracle 11g R1 on Ubuntu 9.04, both 32-bit. This time, I’ve used VirtualBox to run a virtual machine (VM) to perform our work.
We will start with an overview of the AQ technology in Oracle database – what it is and what it let you do. Then we will see how it’s used in Oracle E-Business Suite and how to manage it. Our speakers for the evening are your fellow SOM members – Jurijs Velikanovs and Warwick Sands. TBC.
No doubt you want to cast you first vote for my abstract — Developing Plug-ins for Oracle Enterprise Manager by example :) This presentation starts with an introduction of Enterprise Manager’s Extensibility features and walks the audience through the basics of creating a new plug-in. This session will also demonstrate some proven plug-in development steps based on the experience gained from developing MySQL management plug-in. Session includes a demo of the plug-in development scenarios. After this presentation, attendees will be able to design and develop management plug-ins for their own applications. Login to Oracle Mix and vote now. At the time of writing, my session is on the very top — help to keep it there! ;-)
The first videocast was quite popular — it has more than 300 views in couple weeks and considering no Hollywood stars were starring in that video and there were no nude scenes, I think it’s fair to say that this format was very much welcomed by the audience. Today, I’m posting the follow up session on VIP’s (Virtual IP’s) with Oracle RAC. What I demonstrate today is a typical configuration mistake for a RAC databases created with Database Configuration Assistant (DBCA) and what’s the result of such omission.
I’ve been just sending the abstracts for UKOUG 2009 Conference before the extended deadline is over and realized that I hadn’t spread those exciting news. Actually, the news spread via Twitter before I saw the official confirmation in my inbox. Well, I guess the blog post title says it all. It’s a pleasure to join this program and get engaged in its activities.
