Management

Video : Multitenant : Memory Resource Management for Pluggable Databases (PDBs)

In today’s video we’ll discuss how Resource Manager allows us to manage the memory usage in PDBs. This can be useful to stop a small number of PDBs using all memory assigned to the instance.

This video was based on this article.

Video : Multitenant : Dynamic CPU Scaling – Resource Manager Control of CPU using CPU_COUNT and CPU_MIN_COUNT

In today’s video we’ll discuss how Resource Manager can control CPU usage in PDBs using the CPU_COUNT and CPU_MIN_COUNT parameters. Oracle call this Dynamic CPU Scaling. This can be useful to stop a small number of PDBs using all CPU resources assigned to the instance.

This video is based on the following article.

Video : Instance Caging to Manage CPU Usage

In today’s video we’ll discuss instance caging to manage CPU usage. This can be useful when we are trying to consolidate multiple instances on a single server.

This video is based on the following article.

Will I Be The Next President Of The UK Oracle User Group?

I’ve decided to put myself forward to be President Elect of the UK Oracle User Group (UKOUG). The position of President Elect is, in effect, President-in-waiting. You shadow the current president before taking over the role when their term comes to an end. In this case, that will be in a year.

Friday Philosophy – Condoning Bad Behaviour

I used to work with a man called Nick(*). Nick was friendly enough, he was good at programming and he had very few annoying personal habits. Nick was easy to work with.

Friday Philosophy – Improving Your Working Life

If I got you all to write down the top 5 things that make working bearable, and then got you to make a list of the top 5 things that make working enjoyable, I have a suspicion there will be one thing high on the “Enjoyable” list that may not even be on the “Bearable” list:

Being in a good team.

This one thing can make a real difference to your working life. I know this is true for me and it’s something I’ve heard other people say a lot. The team you are in can make up for a lot of negative things about any given job. I’ve found myself in roles where I am unsuitable for the task, or under a ridiculously high workload, even being paid much less than I know I am worth. But if I have been in a good team, working with people I like (well, at least some of them!) it makes it all a lot better. A lot, lot better. Think about the jobs or roles you have most enjoyed in your life. In any of them did you not like the team you were in?

Friday Philosophy – “Technical Debt” is a Poor Term. Try “Technical Burden”?

Recently my friend Sabine Heimsath asked a few of us native English speakers what the opposite of “technical debt” was. My immediate reaction was to say:

I’d say (sarcastically) “proper development” or “decent designer” or even “what we did 25 bloody years ago when we were allowed to take pride in the software we created!”

But my next comment was less reactive and more considered. And that was to say that I did not like the phrase “Technical Debt”:

A debt is when you owe something to someone, to be paid back. You do not owe anything to someone when you build poor systems, you are actually creating a “technical burden” – something those in the future will need to live with and may eventually have to sort out. Those who created the bad app or design will probably not be the ones fixing it – as in paying the debt.

My New Book!

After what seems like eons since we first started on it, I’m excited to announce a new book I co-authored is finally out. The book is called “Building Database Clouds in Oracle 12c” and is available on Amazon. Of course, it really isn’t that long ago that we started writing the book, but there’s been a lot happening between then and now!

The book was co-authored with Tariq Farooq and Sridhar Avantsa. Tariq asked me to write the material on Enterprise Manager (chapters 4 – 8 in the book), which was done over a number of releases of EM12c. We deliberately left the material on the versions it was written on, because people are still on a variety of different releases, so you can see how it applies in the version you’re using.

From a content perspective, this is what the book covers:

Friday Philosophy – Being the Best Manager

I’d like you to spend a minute thinking back on your career and decide who your best manager has been.

Surely your best manager ever deserves a good cup of tea

Surely your best manager ever deserves a good cup of tea

I don’t mean the manager who you personally got on best with or was most popular with the team – though being one (or even both!) of those does not rule them out as being the best manager you had.

It does not have to be in IT – or even work, actually, cast the net wide to include people who have managed teams and groups outside of work that you have been in.

Determining What Management Packs Are Needed

In Enterprise Manager 12c, there was a little known functionality where you could check what management packs you needed to be licensed for to use a particular page in Enterprise Manager. I referred to it many times at conferences I was presenting at, and almost always people did not realize the functionality existed. Let’s see how this works.

To start with, I’m going to go to the Performance Home page for a particular database (accessed via the Performance menu from the Database home page). Note I’m not particularly interested in what it shows me, I’m just using this as an example of a page that requires the licensing of a management pack. Once I’m on that page, I can follow the path Setup -> Management Packs -> Packs for this Page:
