Red Hat Enterprise Linux (RHEL) 7 Released

It feels almost like heresy to discus something that isn’t Oracle-related on the day that Oracle announced the new In-Memory Database Option, but something else was also released today. Red Hat gave birth to Red Hat Enterprise Linux (RHEL) 7.

I’m a big fan of all things Linux. I’m typing this blog post on a Fedora 20 desktop at home. I’m a rabid fan of Oracle Linux for servers at home and at work. As a result, the birth of RHEL7 is a pretty big deal for me.

EM12c Rel. 4, the Security Console

Why is the Security Console an important new feature?  I was contacted by three people just this last week on how to secure an EM12c environment.  How many of you are still logging in to the EM12c console or CLI with the SYSMAN account?

Bad DBA, BAD!!  :)

Enterprise Manager Cloud Control 12c Release 4 (12cR4) Articles

I’ve started to play around with Enterprise Manager Cloud Control 12R4. The clean installations on Oracle Linux 5 and Oracle Linux 6 were really easy. You can see how I did them here.

I used 11.2.0.4 as the database repository. I’ll probably have a go with a 12c database in future, which is now supported, but my main focus this time was to check out something similar to what I have at work. Forgive my caution, but I’ll not be using 12c database for my EM repository for a while yet. Cloud Control is too important to risk…

The *New and Improved* Extensibility Exchange is Here!

How many of you use Oracle Enterprise Manager 12c, recognize it can do so much more than just taking it out of the box and plugging it in, then proceed to start building metric extensions, plug-ins, writing EM CLI scripts, etc?

Fame at last!

Someone, who shall remain nameless (Eric Yen), just pointed me to this example of creating a credential in the 12c manual.

Looks kind-of familiar! :)

I mentioned in my 12c scheduler article that the DBMS_CREDENTIAL package is used in pretty much the same way as the old credential procedures in the DBMS_SCHEDULER package. So much so that someone has taken the example from my 11g article (here), replaced the package name and put it in the 12c documentation.

Hadoop as a Cloud

The idea of clouds “meeting" big data or big data "living in" clouds isn’t simply marketing hype. Because big data followed so closely on the trend of cloud computing, both customers and vendors still struggle to understand the differences from their enterprise-centric perspectives. Everyone assumes that Hadoop can work in conventional clouds as easily as […]

Hadoop is Not Merely a SQL EDW Platform

I was recently invited to speak about big data at the Rocky Mountain Oracle User's Group. I presentedto Oracle professionals who are faced with an onslaught of hype and mythology regarding Big Data in generaland Hadoop in particular. Most of the audience was familiar with the difficulty of attempting to engineer even Modest Data on […]

Oracle Enterprise Manager 12c Release 4

Funny how there is no mention of the name “Cloud Control” in the latest announcement. Does that mean we are back to calling it just Enterprise Manager again?

Anyway, the latest instalment of EM has been born. The downloads are available on OTN.

I’ve got mine downloading. The past few versions have been relatively easy to install on a clean system, but the upgrades have been a total pig. I’m hoping this one is going to be significantly easier… Sucker… :)

Cheers

12.1.0.4 is HERE!!

After many months of work, Enterprise Manager Cloud Control 12.1.0.4 has finally been released. It’s a pretty big release, both in terms of the number of enhancement requests that have been added as well as the amount of new functionality. Broadly speaking, the main areas of enhancement in this latest release are: Framework enhancements, such […]

The DBSNMP Account and User

I talk a lot about Enterprise Manager 12c, from the OMS all the way to the EM CLI and the Agent, but I was discussing some interesting history with the account used by the OEM Management Agent- the DBSNMP account.
