As many of you are aware Quest provides a tool known as Benchmark Factory, BMF for short. BMF is a load generation tool that also allows you to install small databases for testing. The tools out of the box can provide TPC-B, TPC-D, TPC-H, AS3AP and many other standard benchmarks as well as allowing goal and scalability tests from your own code, either manually entered or scanned from text or, in the case of Ora ...

On March 26, 2008 I gave a webcast on physical tuning named “Goal! Success through Storage.” Due to some delays starting it overran a bit so I wasn’t able to answer questions afterward as I usually do. So, here are the answers to all the questions that weren’t handled by Darren Mallet (who handles the questions online when I am webcasting, thanks Darren!)

In my ten plus years as a database consultant before joining Quest Software I had the opportunity to visit hundreds of client sites. At client sites I performed analysis of their environments to help them improve the performance of their database systems.

I was working the other day to rebuild my Linux 32 bit cluster in preparation for doing some tests between OEM and PAO for some internal training. I planned to use raw for my cluster configuration and voting files for CRS and ASM for the rest of the shared files. The 32 bit cluster had been up and operating fine and I had completed the testing I was doing so I retasked the drives to build a 64 bit cluster. I dr ...

Well, I decided that Linuxtown wasn’t going anywhere very fast and with the all the SRs I was leaving in my wake I soon would not be welcome by the locals so I decided I would take it on the lamb over to Windowsville for a while. Besides it was looking like the local disk array was going to pin a power supply failure on me.& ...

I am participating in the Oracle11g beta. The next time I tell you I am going to do a beta please lock me up until the fit passes. I have subjected myself to this abuse since Oracle8, usually tied with writing or updating a book. Maybe I am getting smarter as I get older as I am not (currently) involved in a book project although there may be one or two mor ...
