As part of the projects I work on at Oracle, it’s often ensuring that those customers that wish to deploy Enterprise Manager, (EM12c) to large environments, have the correct settings and are tuned to offer the best performance from the Oracle Management repository database, weblogic and up to the console URL’s accessed by users. This means that these large environments often receive recommendations from our experts that differ from what EM12c comes “out of (more...)
Metric thresholds have come a long way since I started working with OEM 10g. I remember how frustrating it could be if an ETL load impacted the metric values that had to be set for a given IO or CPU load for a database when during business hours, a much lower value would be preferable. Having to explain to the business why a notification wasn’t sent during the day due to the threshold (more...)
Some time back, I posted a blog entry about Metering and Chargeback in Enterprise Manager, where I covered the basic capabilities of the Chargeback Application. It’s taken me some time to get back to the promised followup blog post on setting up Chargeback, what with Oracle Open World getting in the way of things, but that’s what I’m finally doing now.
Chargeback can be setup in EM12c by any user with the EM_CBA_ADMIN role, or (more...)
If you want to download the slide deck, here it is. As always, I would really, really like to hear from you.

Yet again the monster that is Oracle Open World is about to take over San Francisco. I won’t be making it this year, but considering we had something like 60,000 attendees last year I’d hate to see what the numbers are gonna be this year!
To try and make it a little easier for you to find all the Private Cloud and Lifecycle Management with EM12c material, here are the ones I know about. If (more...)

On the Maximum Availability Architecture website, there’s a paper on <awful term alert>Best Practices</awful term alert> for Database Consolidation. It’s a great paper, as you’d expect from the MAA guys (well, apart from that awful term alert I had to add! ). Since database consolidation is an area I work in a lot, I thought I’d start looking at implementing as much of their recommendations as I could in Enterprise Manager, which of course is (more...)
When I normally start work on a new EM 12c environment, I would request to have a userid created; however, I don’t have a userid in this environment and I need access EM 12c as SYSMAN. Without knowing the password for SYSMAN, how can I access the EM 12c interface? The short answer is that I can change the SYSMAN password from the OS where EM 12c is running.
Before changing the SYSMAN password (more...)
In case you haven’t noticed it – and chances are you haven’t noticed because I just created it! – I’ve added a new page called “Tips and Techniques” to the website. It’s where I keep a random collection of odd items I’ve come across that might be of interest yet don’t deserve a full blog post. It’s sort of like a FAQ list, but not necessarily with the “F”.
You can reach it either via (more...)
This is an interesting point that came up recently, where someone had a DBaaS environment running on an Exadata system for a couple of months, with no issues. It has recently started to return errors on the Database Cloud Self Service portal in the “Placement Algorithm” region:
Constraint : Number Of Databases
Current Resource Usage: 18
Total Resource Available: 10
Maximum Limit Defined: 10

Depuis quelques semaines, la nouvelle version d' Oracle Enterprise Manager (22.214.171.124) ainsi que les bundle patches pour OMS sont disponibles.
Si vous prévoyez de d'appliquer ces patches et que la problématique d'arrêt de service vous concerne, il est désormais possible de réduire le temps d'arrêt.
Le document intitulé "Reducing Downtime While Patching Multi-OMS Environments" contient les instructions et les étapes pour cela.
