Real Application Testing report On Premise vs. Oracle Public Cloud

Just a quick post today as I wanted to highlight a video that has been made available by one of my colleagues, Valentin Tabacaru. Valentin is a sales consultant based out of one of our Spanish offices. The
YouTube video shows a SQL Performance Analyzer execution and report generation using real world workload testing between On Premise Oracle 11gR2 Database and Oracle Public Cloud 12c Pluggable Database Service. Both environments are managed using EM12c providing (more...)

PeteWhoDidNotTweet returns from the dead!

If you attempted to get to PeteWhoDidNotTweet over the past few days, you would have noticed it was down. The reason for that is I finally found the time to do something that I’ve wanted to do for some time – perform a major update of the entire website.

A few weeks back, I finally managed to get on a WordPress course (WordPress is the software that the site runs on, of course). I had (more...)

Snap Clone on Exadata

Recently I created a new screenwatch that walks you through the new features of Snap Clone on Exadata in Enterprise Manager 12c version 12.1.0.5. The screenwatch walked through using Snap Clone on Exadata, both from a multi-tenant architecture perspective and a standard non container database perspective. Unfortunately, putting both together meant the resultant video was around 20 minutes long.

Generally, we try to make our screenwatches shorter than that, as the evidence (more...)

EM 12.1.0.5 has been announced!

The latest version of Enterprise Manager, EM 12.1.0.5, has been announced! The announcement can be seen here. Obviously, there will be a number of posts that come out about it over the next few weeks, so I’ll add this post here as a quick notification and will update it with links to more information as it becomes available.

EM Express versus EM Cloud Control

Recently I was asked the question “What is the real difference between EM Cloud Control [NOTE: I’ll refer to this as EM12c through the rest of this post] and EM Database Express in 12c?” It was (for me) a pretty easy question to answer, but I wanted to provide the questioner with a link to the place in the Enterprise Manager documentation where it covers that in detail. Somewhat to my surprise, I wasn’t (more...)

Installing Enterprise Manager 12c For Testing

A question I get asked fairly often when I’m at conferences, either during the Q&A for my sessions or in general chit chat (a.k.a. networking) afterwards is “I want to play around with the features in Enterprise Manager 12c but don’t want to do that in our Production environment. How do I go about installing a copy of Enterprise Manager 12c somewhere else in the easiest way as a test environment?” The (more...)

Troubleshooting Target Status Availability Issues

If you’ve been using EM12c (or any of its precursors for that matter), you’d know that it can sometimes be problematic to troubleshoot an availability issue for targets.  You can see they might be up (hopefully!), down, pending, unreachable or showing a metric collection error, but understanding what’s causing that particular status (and indeed why it can sometimes be wrong) can be difficult at times.

Thankfully there’s a couple of Information Publisher reports (more...)

Data Subsetting

Recently a good friend of mine posted his thoughts on data subsetting. As you would expect from Kyle, it’s a well-reasoned discussion (well, till he went down the path of using Delphix 😉 ) but I wanted to add a few extra comments. It’ll probably take longer than a quick comment on his post, so let me add my 2 banana skins worth here then link to this discussion back on his post.

So Why Subset?

Collaborate ’15

It’s time for another phenomenal Collaborate conference next week, made even more fabulous by the fact that I’ll be there for the first time! :) For some reason, Collaborate is one of the few big user group conferences I haven’t made it to before, so when my boss asked me to go and present at it I leapt at the chance.

Originally, I had one presentation timeslot, but then Alex Gorbachev of Pythian / Oak Table (more...)

Data Cloning and Refresh

For some time now, I’ve been creating blog posts that walk you through using some of the Enterprise Manager technology to perform specific tasks. For example, there’s one here on setting up Chargeback in EM 12.1.0.4. I’ve never been really satisfied with the way these blog posts turn out, as to document a step by step process like this takes lots of screenshots and you end up with a post that’s a (more...)
