Offers effective monitoring of resources but lacks the ability to connect to an AWS instance and write custom queries.
We use it mainly for monitoring, including CPU, memory, and disk space, and for troubleshooting purposes We've set up alerts to notify us when performance deviates from the baseline we've configured for each resource. So, whenever that happens, we get an alert and can investigate immediately. So,…

Extensive functionality impresses despite occasional setup complexity
The functions and features of Oracle Enterprise Manager that I have found most valuable are its evolution from being problematic in 10g and 11g versions to becoming better and more stable. Now it has become a significantly improved product. We have integrated identity management, and we are using it for normal database examination, tuning, and performance. We are working with STATSPACK and similar tools that are integrated in Oracle Enterprise Manager. We are currently working with version 13.5, having upgraded from 13.4 last year. Automation is useful for improving operational efficiency, and there are many more opportunities to automate outside the databases. Not many things need to be automated inside the databases. We have jobs running, imports, exports, and similar tasks. To automate these processes, we utilize the Scheduler from Oracle, which is managed in the databases by the vendor. This is not part of our DBA functions in Oracle Enterprise Manager.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"One of the things that it is used for is to detect anything that could possibly cause our systems not to function well, and it has helped us to determine that before anything has actually happened."
"Baselining our SQL Servers has made a huge impact."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"Memory and CPU utilization features are good."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"The ability to go back and look at historical data is the most valuable feature."
"It is a must if you have more than a couple of databases to monitor and manage, it can also do a lot of other stuff and monitor various types of targets."
"We can manage everything in our environment."
"We get good support, tickets are resolved quickly and we are happy with the resolution."
"Oracle Enterprise Manager 12c is a transformational technology that comes with a set of comprehensive features and great practices that help IT transform into a true enterprise Cloud that delivers on business needs."
"The tried and tested services that Oracle provides is second to none."
"We need 99.9995 uptime, and Oracle Enterprise Manager helps us to achieve this goal with its superior monitoring and management capabilities."
"Excellent product for enterprise monitoring: The tool is able to monitor several other database products across various OS platforms."
"It's a useful feature to be able to see the top SQL, the number of executions, the CPU, and the resources that it's using."
 

Cons

"Reporting and overall analysis of data gathered from SQL Server."
"Scalability is what I mentioned earlier, regarding room for improvement. It doesn't seem to scale out to an environment as large as ours, with just a single monitoring server."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"The initial setup gives too many user rights to the server, so you have to put a user that is part administrator's group - that's the preferred way - on each server, which is kind of a risk. You want to do least privilege and you're not doing that."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"I don't have that functionality, which is very disappointing. That's pretty bad and frustrating because I could query it and find out so much information about what's hitting my environment and when, but instead, they want control over it and to not give me that information."
"I would absolutely love to create customized dashboards but, unfortunately, they don't provide me the information that I need to create the report. The report I need is the detail or the transaction detail that's happening on those Snapshots. I'd like to be able to go back through time and search for things. I don't have that functionality, which is very disappointing. That's pretty bad and frustrating because I could query it and find out so much information about what's hitting my environment and when, but instead, they want control over it and to not give me that information. So it's encrypted. I can't pull it out and that is really bothersome."
"Technical support could be faster."
"One of the drawbacks that I don't like is, quite often you'll see that the agent will show a status of Pending."
"Customer Service: 2 out of 5. I often choose to open an SR as a last resort."
"The solution is considered expensive."
"With regards to masking still, some options could be added like running in simulation mode, creation of audit file option, file summary, file after masking."
"I would say mostly backup and recovery, through the Enterprise Manager. Or any corruptions, to be able to fix them through Enterprise Manager."
"The platform's interface could be more streamlined. Currently, there are multiple ways to navigate to a specific point, which can be confusing."
"For databases and servers with high blocking issues, the monitoring and graphs in OEM frequently became so overloaded that they could not be used and would not load, making OEM useless for troubleshooting certain production issues."
 

Pricing and Cost Advice

"The pricing is reasonable, it's comparable with the competitors."
"We were upgraded to Premium Support without their actually asking us, when we were quoted. Then I asked for Standard Support and that they had to re-quote us that. But they don't do that by default. They upcharge you by default, which I didn't think was very nice, without even asking."
"We are satisfied with the pricing."
"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."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"Oracle Enterprise Manager is a free tool from Oracle."
"The solution is free."
"The basic functions are free. You only pay license fees for advanced features."
"It's expensive."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
