Does anyone use Oracle Enterprise Manger and Gird Control?

I’ve been running Oracle 10g RAC in production since it was released, but in all that time I’ve probably had the DB Control running for about 10 minutes. Now admitedly we’re talking about an Oracle product on Tru46, but I can not believe how much memory it takes up. If I leave it on for more than a few minutes it grabs about 450M of memory. I don’t know about you but I can think of much better uses for that memory.

I foolishly decided to give grid control a go. Now the agents on database nodes were fine. They didn’t take up too much memory or CPU, but on the app servers they went berserk. We’re talking 500M of memory and 20-40% of the CPU. The crux of it is, in order to monitor the performance of your box you have to kill the performance of your box. I suppose the plus side of it is that it sends you an email to tell you that the agent processes are killing the box.

Needless to say, the whole OEM and grid control thing is not what I expected. Of course the TAR I raised about the problem resulted in a generic platform bug report that now claims it has been fixed in the next version of Grid Control, which I guess will come out soon after 10g Release 2.

So back to the question that is the title of this post, has anybody got this stuff to work without a massive investment in hardware just to run the agents?



Old fart of Oracle in the making…

My company has just bought several PL/SQL Developer licenses and it’s a pretty good tool, but every time I edit a source file I keep accidentally using my beloved UltraEdit (a posh text editor). I then compile the code using SQL*Plus.

Now I know that PL/SQL Developer is designed for the job, but I have everything I need with UltraEdit. I don’t need a code beautifier because I know how to indent code. I don’t need a debugger as I instrument my modular code. I’ve had syntax highlighting for years in UltraEdit.

I’m seriously starting to think I’m becoming an old fart.

Please, somebody validate me. Tell me it’s OK not to use posh IDEs…



PS. I’m thinking of switching from FireFox to Lynx as my main browser. Those new fangled graphical browsers will never catch on…

Debugging the debugger…

I’m having an intermittent problem with a Java Stored Procedure. I raised a TAR with Metalink who asked me to run oradebug against the process to pull out errorstacks. Doing this not only killed the session, but brought down the whole instance and OS!

Next I started to get errorstacks out using dbms_system.set_ev. This seemed to work, but it produced truncated errorstacks.

Now I’m debugging the errorstack production in order to allow me to debug the original Java issue.

The joys of running Oracle on Tru64…

Oracle supporting multiple platforms???

Oracle support their products on a ridiculously large number of operating system platforms. It’s a statement of fact, but in reality what does this mean. Over the last coupe of years I’ve come to believe that Oracle “port” to many platforms, but they can only effectively “support” a limited range of those platforms.

These are my thoughts on the relevance of several operating systems on a per-product basis…

Oracle 10g Database:

Linux – Works very fast and is extremely reliable, provided you are VERY careful about what OS packages you update.

Solaris – I like Solaris, but I question using expensive Sparc hardware when Linux on x86 runs faster. Never used Solaris on x86, but then why would I? That’s what Linux is for 😉

HP-UX – Works well, but it’s a dead platform. Ask anyone within HP and you will know that Tru64 and HP-UX are not long for this world. HP-UX on x86? Yeah, right!

Tru64 – Contact Oracle support for help on Tru64 and you will soon find out they don’t have access to Tru64 instances to test anything worth doing. It’s a great platform but it’s already been end-of-lifed by HP so don’t even go there!

Windows – Oracle works well on Windows, but it’s not as fast as running it on top of Linux, so why put money into Bill’s pocket for lower performance?

Oracle 10g Application Server:

It’s a Linux product. Running it on any other operating system is a waste of time and money.

Please don’t try and run it on Tru64. You’ll spend months fighting it and eventually get HP to replace your Alpha kit with x86 kit for free. It happened to me 😉

Oracle Collaboration Suite:

It’s a messy and overcomplicated product built on 9iAS components. In my opinion 9iAS was a total abortion, and I’m not too fond of OCS.

Anyway, it’s a Linux product. To paraphrase a conversation with Oracle consultants, “It’s supported on a number of platforms but it’s a Linux product.” Enough said.

Oracle E-Business Suite:

See AS10g and OCS.

From this post you might conclude one of two things:

  • I’m a rabid Linux fan.
  • I’ve used Oracle on many platforms and always found the best way to get support is to use the latest version of a product on the platform Oracle prefer and Oracle currently have a love affair with Linux.

I like to think it’s the latter, but I do find myself foaming at the mouth in the presence of penguins…



The ORACLE-BASE blog starts here.

I’ve decided to start a blog because I have lots of thoughts and opinions that don’t really fit in with the article structure on

This blog will also act as a replacement for the mailing list on my main website. I was never happy with the mailing list format. It always seemed a bit too formal to me. This seems more relaxed and informal so for the moment it seems like the way to go.

The existing website will continue in its current form, and this will be the location for my random musings.
