But don’t forget, that once you get those blocks back to Oracle, you (more...)
In this blog, I mostly write about performance issues (and tools to resolve them). I’d like to make a post about performance non-issues for a change. I think it might be interesting for two reasons. One, if not identified early, non-issues can consume lots of resources in terms of developers’ (more...)
Since the version 11G it is possible to exclude committed blocks from specific tablespace from being written to flashback recovery area. FBDA process writes committed blocks to flashback area and is quite IO intensive. There are, among other things, flashback checkpoints as well. They occur when when flashback logs fill (more...)
Zebedee has just boinged onto my TV screen on his big-spring lower body and told us all that it is “time for bed”. I concur Zebedee. Good night everyone!
For those of you who are not of UK origin and of “a certain age”, Zebedee was a character on the (more...)
Oracle allows you to download most of its software free of charge via the OTN Developer License.
This is a fantastic option that I appreciate a lot. But it is important to understand the restrictions of the license.

Even the great ones do misspeak from time to time. And when they do, this can lead to a terrible mess in people’s heads.
Here is one example:
Are you at 100% utilization? If not, you haven’t accomplished your job yet. You cannot
put CPU in the bank and save (more...)
I work for a company that provides betting to consumers in Australia…
In Australia, the three biggest days for betting are typically:
- Melbourne Cup (horse race)
