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

"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"We're able to diagnose issues prior to their actually becoming issues. Without the alerting, we wouldn't have a clue as to what was going to happen. With the alerting, it gives us a heads-up that a specific threshold has been met, and we need to take specific action."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"The most valuable features are disk space projections for planning, and also the Snapshotting ability, to look back in time, to see what was going on the server at a particular time."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"The ability to go back and look at historical data is the most valuable feature."
"Baselining our SQL Servers has made a huge impact."
"Some of the most valuable features are its real-time performance view/dashboard, metric history, real-time monitoring and alerts, as well as quick access to Oracle's tuning and diagnostic options."
"This solution was the only one which allows us to monitor all our solutions from one interface."
"I have found the uptime of all of our systems to be most valuable with this solution. This is important because we need to guarantee specific uptime and preventive maintenance. We need to know upfront if there are going to be any issues on the database so we can proactively solve those."
"As a troubleshooter, I was able to quickly resolve memory issues."
"Customer service is good and technical support is very good."
"It is a scalable solution. So far, my company has not faced any issues with the scalability part of the solution."
"We use this solution to monitor the server, looking at the system, and maintaining it."
"This solution allows us to quickly drill down when there are issues."
 

Cons

"I'm going to do an upgrade which may resolve my issues, but one area for improvement is its ability to handle the amount of data that we collect with it. We're likely one of the largest installations, with over 300 servers being collected with this product, and sometimes there are gaps. That would really be my only concern, in terms of how the data is collected and stored, for consistency."
"With basic SQL training in my history, I've found at times I needed to Google SQL counters, for example, to understand what was occurring or how to configure SQL DM to be useful."
"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."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"Some more granularity in alerting."
"The one area was the process of setting up targets and hosts as it seems rather lengthy and repetitive."
"Some of the new features it could give us: maybe access to some of the taxation data and also some of the other benefits it could include as part of the system."
"If you see the documentation, it's not really that much good."
"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."
"The weaknesses I would like to address in Oracle Enterprise Manager involve the dealing of Grid Infrastructure."
"We would like to have a single dashboard for monitoring and controlling all of our products. This would add value, for us, because as it is now, we have to go to different screens to check different products."
"In my experience, the monitoring could be improved."
"It could improve in some areas like the screen. It's not so clear for the novice, when a new person looks at the screen he/she may not really understand where to start first."
 

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."
"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."
"The basic functions are free. You only pay license fees for advanced features."
"The product is highly-priced."
"The product is very expensive."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"The solution is free."
