The presentation in two parts was exactly what an Oracle DBA like me would need to have a peek into the security territory of SQL Server. I was afraid it would be really “deep dive” and assumed lots of SQL Server knowledge but I was actually fine. I think it would be cool to have a full day real deep dive and looking at what Peter was talking about, I’m convinced that he could keep going further and further into details should we give him more time.
I was very surprised that Oracle released Oracle Database for Mac OSX, especially, version 10g now that 11g has been out for almost 2 years. There is no quick install guide for OS X but only a standard Oracle® Database Installation Guide 10g Release 2 (10.2) for Apple Mac OS X (Intel). It’s fine but if you want to install Oracle on your MacBook and not for production use then you might take some shortcuts and follow a quick instructions so I gathered my notes while installing just released Oracle Database 10.2.0.4 on my MacBook, here they are.
I presented my session Under The Hood of Oracle Clusterware and it went quite well and even the demo worked so we didn’t get to the fun troubleshooting experience. I love when the audience is actively engaged and presentation is not “one-way” — lot’s of fun (and spare time to refill while someone else is talking). We had a nice break between two parts of the presentation and, instead of 10-15 minutes bio-break, it turned into 30 minutes of peers networking and, unfortunately, I had to interrupt it in order to continue. Note to myself, we should plan to have more free flowing discussions and also plan small meetups directly in a pub, maybe.
I’m excited to announce that Paul Vallée, Pythian Founder and Executive Chairman, will be on-the-air online this week with a free webinar — Database Platform Migration: when is it strategically appropriate to migrate existing applications to an open-source platform? It’s based on our 10+ years experience supporting proprietary databases, such as Oracle and SQL Server, and open-source MySQL databases on the other hand and what we learned on the numerous migrations.
This is not a complete guide on the Oracle RAC install with VMware Fusion but just the hints on setting up shared storage for Oracle RAC using Mac as host for VMWare Fusion virtual machines (VM’s). The reader is assumed to understand how to setup Oracle RAC and has general understanding of VMware itself. There are plenty of guides on the Internet on how to setup Oracle RAC including VMware but they usually refer to VMware Server on Linux or Windows. Please note that I’m writing it largely by memory so if you hit any issue — please leave a comment.
I have been presenting about RAC Connection Management on a number of conferences and I have done a white paper that is focused on RAC Workload Management. It was available to the conference attendees and now is publicly available so read on.
Gday everyone. This information would be most useful for the Oracle professionals in Sydney, Australia. I’m very excited to announce the Sydney Oracle Meetup (SOM). We will be meeting regularly starting on Tuesday, 31st of March 2009. For each event, I’m targeting to have one or two speakers — sometimes with a formal full blown presentation and other times with rather informal whiteboard style sessions. The target is to meet fortnightly if we can manage such pace.
don’t want to post the link to this (perhaps, it was left public unintentional?) but here is what I stumbled upon recently. This is a log of production maintenance of IT systems in Perth, Western Australia (as far as I could say): Good idea but shouldn’t companies keep this sort of information private?
Pythian DBA’s have daily reports for each monitored database and some of the components are using charts to visualize the data. I’m a big fan of charts myself (when applied appropriately) and want to show how you can generate simple charts directly from the database. You’d be very surprised how easy it can be done from *any* database without installing any additional software or configuring something special.
I apologize for off-topic on this blog but I think it’s important…Victoria experienced unprecedented bushfire this month taking lives of almost 180 (the list is growing) people and leaving thousands without homes. This disaster left tears on everyone’s faces even outside of Australia. If you would like to show the compassion and provide some help there are few ways. One of them is to contribute to the Red Cross Bushfire Appeal 2009. You don’t have to be in Australia to do that — you just need to have a big heart and few bucks to share.
