Pour activer AWR Warehouse, l'administrateur d'Enterprise Manager doit :
- Créer une instance de base de données Oracle Database 18.104.22.168 (recommandé) ou 22.214.171.124+ pour le référentiel AWR
- Découvrir l'instance dans EM12c
- Appliquer le patch sur l'OMS (cela permet d'avoir AWR Warehouse dans le menu)
- Appliquer le (more...)
The webinar is over, but you haven’t missed out on everything I presented on the console feature, under the hood and behind the scenes!
Thanks to everyone who attended and a big thanks to GP for doing the introduction and ODTUG for hosting us!
We went over a few of the Java “tuning” options last time, so let’s go onto the OMS tier for this post.
Location, Location, Location
High latency issues between the OMS(Service) and the OMR, (Repository) when separated by geographical location is common. It’s important when designing the Enterprise Manager environment that you keep your OMS hosts close to the repository hosts geo-locationally. Your agents can be global, with minor network considerations, but the (more...)
In my recent post I already mentioned it a little bit: Integrating your manual Data Guard Broker configuration in OEM Cloud Control can become a sort of climbing a Mountain. And it doesn’t have to be.
But first a short description of the situation. I have a working Data Guard broker configuration between two Cluster Databases running Oracle 126.96.36.199 on linux x86-64. Both clusters have an Cloud Control agent (188.8.131.52) (more...)
The last few months I’ve been working with Oracle Data Guard, reading lots of manuals and (parts of) books, to make smart decisions and get a solid foundation. I consider myself part of the people who like to work with the command line. That way you really get to understand what you are doing and you won’t have to panic when you don’t have a GUI at your disposal. Once that’s an acquired skill I will (more...)
I’ve already talked about the recommendations we make for properly sizing an Enterprise Manager 12c and many already know about tuning a database, but let’s look at the tuning that may be a bit foreign to DBAs. We’ll start with Java.
We all know that it’s part of the EM12c architecture, but we often don’t realize that it requires attention to assist in Enterprise Manager running efficiently.
The Java component of the (more...)

I often hear, “My EM12c environment is slow!” and I just as often am granted access to the environment and find out that EVERYTHING is running on an old single core server with 2Gb of RAM someone found lying around. Enterprise Manager is often an after thought to many IT organizations. After all the work has gone into the production environments that build revenue, there is often a disconnect on how important (more...)
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!!
The Security Console helps the administrator set clear expectations for security standards for database administration and EM12c environment security. It provides read (more...)
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? How cool would it be if you could peruse a library of plug-ins to support the extensibility framework for you to check out and use for the benefit of your company and you?
