We all know it's really hard to get good pricing and cost information.
Please share what you can so you can help your peers.
The pricing is very high.
Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive. Be careful to only enable the packs for which you have a license as this is an issue we see time and again. I.e., customers who do not understand the licensing model have not turned off access to packs that they are not licensed for, then get into legal issues for it later.
The basic functions are free. You only pay license fees for advanced features.
License version..does not cost too much due to license and agreement between vendor and company.
Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts. Day-to-day is very roughly $100 for routine patching and maintenance. High-availability significantly may double or even triple these expenditures, but for some environments that's inevitable. If one system needs that level of oversight, then all of the infrastructure will be managed to the same level of oversight by OEM. There is also an augmented set of separate, but useful features being added under the Oracle Management Cloud suite of products designed to focus more on analytical problem identification (such as when one issue triggers a seemingly unrelated set of other symptoms) and leverages the power of mass target data agglomeration at the expense of having costs driven by the volume of data being recorded. But this is typical of most cloud-based solutions, where bandwidth utilization is a cost driver. Oracle Management Cloud is basically a VM environment spun up in the region containing your systems to be monitored and managed. Oracle do not support cross-region management using OMC (however, you can do that with additional plugins to OEM on-premise) so if you run VMs actively in more than one region, you'll end up with multiple OMC systems, and the associated costs. Be aware, you are charged in many different levels, but mostly to license the product itself, the cost and storage to run the VM, and then storage to injest and store however much logging and data you want to retain for the puposes of monitoring, troubleshooting, auditing, and forecasting growth. This is quite different from on-premise monitoring costs which usually are limted to a base license, plus support subscriptions, and then incremental spends for increasing base storage for the hosts. It's best to proceed slowly and incrementally when adding systems to OMC to monitor, so you can baseline and measure how much each system costs in-total to monitor, and determine what level you want to monitor each system (Enterprise and Standard monitoring templates are available and can be dynamically switched for each system, or the whole OMC target inventory.)
The initial setup was probably a couple of hours of installation time. Besides applying the quarterly patches which takes 2 - 4 hours (we have two Cloud Control environments) another "cost" is hardware resources on a VM. There are a few bugs with the software which require opening SRs with Oracle Support which contribute to the day-to-day cost. Perhaps 8 hours per month is spent dealing with support, just as a rough guess. I would highly recommend the Tuning and Diagnostic Packs for OEM to greatly aid performance tuning with come with additional licensing fees.
