This process can be used for most 11G upgrade projects. Very often a hardware got updated at the same time as a database version. In such case we migrate a database from an original location to a new server upgrading database version and sometimes changing operational system. If this is your scenario then you can use the upgrade process to minimize system’s downtime to 1 hour independently from size of the database you migrate.
This blog post is a short summary of one of our migration strategies used to migrate Oracle 10g databases to ODA balancing the requirements of minimal downtime and efforts/costs of the project.
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 database. Some time ago I created a survey,”Why do you use RMAN catalog DB for your Oracle DB backups?” In this blog post I am sharing the survey’s results.
SLOB on steroids v0.1 (you use it on your own risk). If you don’t know what is SLOB read here.
First of all if you are using NFS to store Oracle database data files I strongly advice you to enable Oracle Direct NFS (DNFS) to access those files, the main reason is performance. DNFS removes a serialization point over the traditional “kernelized” NFS. However if you are not using NFS then most probably DNFS is out of interest for you and you should stop reading, but if you want to set it up lets 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. The group can be accessed through the following link
This posts finalizes a few weeks work on comparing SLOB and ORION IO testing tools.
In this blog post I share physical IO testing results I got running SLOB and ORION on the same system on the same disks. I will use those results as a reference in few next blog posts. 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 at future conferences. Let me start with 4 speakers that I didn’t hear before Collaborate 12.
I just installed 3.1.1 Oracle VM server for training purposes on my sandbox and faced the same issue I faced installing 3.0.3 and 3.0.1 versions before. I quickly found a workaround that worked for me. But as 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 (Oracle may be ;). Anyway this is that I found.
