Backup is one of the most important topics for any Oracle DBA. It is our primary responsibility to make sure that at any point in time we can recover a database. Some time ago, I created a survey (my very first one): “Why do you use RMAN catalog DB for your Oracle DB backups?” In this blog post, I will share the survey’s results.
SLOB on steroids v0.1: Use it at your own risk. First of all, let me state that I’m falling in love with SLOB :).
First of all, if you are using NFS to store Oracle database data files, I strongly advise you to enable Oracle Direct NFS (DNFS) to access these files. However, if you are not using NFS, DNFS is probably not of interest to you, and you should stop reading here. But, if you want to set it up, let’s go!
This is just a very short blog entry to inform folks that there is an open discussion group over at LinkedIn for SLOB topics of interest.
This posts finalizes a few weeks of work on comparing SLOB and ORION IO testing tools.
In this blog post, I will share the physical IO testing results I got by running SLOB and ORION on the same system and on the same disks. I will use those results as a reference in a few blog posts to come. As of now, I would like to make few points based in the results here.
The purpose of this blog post is to share my favorite speakers list from Collaborate 12 and give you hints on who you may want to listen to at future conferences.
I just installed 3.1.1 Oracle VM server on my sandbox for training purposes and faced the same issue I did when installing versions 3.0.3 and 3.0.1. I quickly found a workaround that worked for me. But as a follow up, I decided to search though Google and MOS in order to see if there has been any good development in resolving the issue from others.
The purpose of this blog isn’t to show off the results of my presentation at Collaborate conference, but to inspire you (and maybe myself in the future) and give you additional motivation to never give up on your dreams if you truly believe in them.
As SLOB takes the IO testing on Oracle Instance level, you need to watch for several things before you declare official testing results. My suggestion is: Don’t take any result for granted. You need to assess those before stating that you are done.
