Autoformat ANY amount item, anywhere

If you’re building a “finance-ey” application you probably have plenty of fields that should show and accept monetary amounts – and quite possibly these items may be implemented in a variety of ways – ordinary apex number items, edit fields in tabular reports, or even dynamically generated items using

Oracle Concurrent Manager, Specialization rules -Standard Manager

I have installed Oracle application R12.1.1 in my computer. By default the Specialization Rules of my Standard concurrent Manager has only 3-4 programs in the 'Include' state(attachment). Everytime I run a program, I need to make an entry here. This is very tedious process. Is there any process to include all the 1000+ programs automatically?

Please enlighten me.


In-memory Aggregation

The title of this piece is the name given to a new feature in, and since I’ve recently blogged about a limitation of the in-memory option I thought I’d pick this feature as the next obvious thing to blog about.

AWR Warehouse

I just noticed last week that there is a new patch for Enterprise Manager and it is enabling AWR Warehouse feature. There is a note ID 1901202.1 which describe bundle patch for OEM 12c release 4.

Today I had a chance to install it in my lab and now I can start testing new OEM feature.

SLOB Physical I/O Randomness. How Random Is Random? Random!

I recently read a blog post by Kyle Hailey regarding some lack of randomness he detected in the Orion I/O generator tool. Feel free to read Kyle’s post but in short he used dtrace to detect Orion was obliterating a very dense subset of the 96GB file Orion was accessing.

Crossplatform transportable tablespaces - part 2

It took some time since I wrote a first post about TTS migration but I finished that project literally hours before my summer break. Now after couple of days while I enjoyed thermal waters and good wine of Hungary it's time to write next post.

Why I don’t like the term “Center of Excellence”

I keep hearing about “Center of Excellence”. The term makes no sense to me. What does it mean? The middle (center) of wonderfulness? A place (center) where one goes to become excellent? Lately I’ve been hearing it used to describe our lab which is just a collection of computer equipment. In our case it’s a bunch of Oracle Engineered Systems. Our lab is really cool because we have a bunch of bad ass toys. I have even started hearing people refer to it as the Oracle Engineered Systems Center of Excellence, which doesn’t really roll off the tongue does it?
