I find myself forgetting on how to disable Oracle AUTO_TASKs on regular basis. Therefore I have decided to document it under this small blog post.

Just received a page about “Corrupt block”. From the first look it kind of scary to receive such page 40 minutes before your shift ends. Right?
After examining an alert.log (see below) and looking through knowledge bases found an explanation that it isn’t as bad as I thought. I liked the explanation I found therefore I decided to share it with rest of the world. Here you go folks
In this blog post I am publishing my SLOB tests results and conclusions testing Oracle database IO performance placing data files on NFS directly and on ASM disk group located on NFS.
My tweet few days ago – “Personally I don’t see the point building ASM on (d)NFS. ASM suppose to exclude unnecessary layers. In NAS case it adds an additional layer.” Since then Oracle people in my Social Media environment helped me to find several legitimate reasons to run ASM on NAS. Thank you folks very much. Now I am sharing our common thoughts with the rest of the community.
There is a very strong Oracle Community in Perth, Australia. I admire many Perth based Oracle User Group volunteers who year from your organizing a great Oracle event.

Disclaimer: much that follows is pure speculation on my part. It could be completely wrong and I’m putting it out there in the hopes that it’ll eventually be proven one way or the other.

I hope that by now you’ve all heard about the fun that is pluggable databases. Oracle 12c will allow you to have multiple databases within the same instance. It is not often that Oracle makes a major architecture change that opens new possibilities. As a consultant it is certainly exciting, I can now imagine new and better-than-ever solutions for my customers.
