I’ve done a couple of play installations of EM12c 22.214.171.124, just to get a feel for it. You can see the result of that here.
From an installation perspective, everything was pretty similar to the previous releases. I tried the installation on both OL5 and OL6, in both cases using 12c as the database repository. No dramas there.
A couple of things of note.
The latest version of Enterprise Manager, EM 126.96.36.199, 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.
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 able to find such a link – well, not quickly anyway. I think the reason for that is the documentation for EM Express (as it’s more commonly abbreviated to) falls under the database documentation which is owned by a different group in Oracle than the Enterprise Manager documentation. Well, that’s my speculation anyway. It may just be there in the documentation and I couldn’t find it in my quick search.
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 answer to that is pretty straightforward. It’s to download the relevant VM template from Oracle’s Software Delivery Cloud. Note: The screenshots shown in this post are from the new and enhanced Oracle Software Delivery Cloud, rather than the classic Software Delivery Cloud, so if you use the classic form your screens will be different. On the first screen, make sure you understand the export restrictions and click “Accept”:
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.
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
A common issue I’ve noted are dump files generated from the AWR Warehouse, but upon failure to transfer, the dumpfiles simply exist, never upload and the data is stuck in a “limbo” state between the source database, (target) and the AWR Warehouse.
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 fame noticed I was attending and asked me to do a couple of slots at Oak Table World on the Wednesday. Then the organizers had a drop-out and asked Seth Miller and I to fill it in, so my dance card is starting to look a bit more full! So dates and times for when I will be presenting currently stand at:
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 188.8.131.52. 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 mile long. It also gives the impression that doing something can be quite complex, when in fact it might only take a few minutes to perform all those steps.
