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

"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."
"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"Memory and CPU utilization features are good."
"Baselining our SQL Servers has made a huge impact."
"The best part of SQL DM is the ability to customize alerts and counters. This allows our team to find an issue then alert on the issue at a granular level."
"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."
"The job subsystem, monitoring subsystem, alerting, grouping of targets, and reporting features are valuable to us."
"We increased our capacity and speed of detection, diagnose and resolution of database issues."
"I really love this tool because I don't need to type the commands, it's very user friendly, I just click and get the reports and get it done."
"The single-pane and single interface in the centralized system is the most valuable feature."
"The look and feel I think. Fast and compatible."
"I rate Oracle Enterprise Manager eight out of 10 for stability."
"I really like how Statspack has evolved into AWR, ADDM and ASH reports, fully automated out of the box."
"The most valuable is when a client calls us to tell us the performance is really bad, I can quickly go on to OEM and see which SQL is causing the problem."
 

Cons

"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"One thing I'd like to see is the ability to view the execution plan and have the system automatically recommend potential query optimizations, especially at the query level."
"We don't find that it helps us with performance monitoring and diagnostics. We find that SentryOne does that better. Also, in terms of alerts, we had to customize them dramatically so that we didn't get alerted on every little thing."
"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."
"Oracle Enterprise Manager's scalability is an area with certain shortcomings where improvements are required."
"Setting up the Oracle Enterprise Manager is challenging as it requires setting up a separate server."
"What I would love to see in Enterprise Manager is more support for the hardware, more support for Bare Metal."
"It needs to support the Database versions lower than 10.2."
"Customer Service: 2 out of 5. I often choose to open an SR as a last resort."
"It can be a process hog sometimes."
"Setting up the Oracle Enterprise Manager is challenging as it requires setting up a separate server."
"The solution's agents work with Java, and the Java code sometimes consumes a lot of memory on the CPU."
 

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."
"Oracle Enterprise Manager is a free tool from Oracle."
"There is only the standard licensing fee. There are no other costs."
"The solution is free."
"The product’s price is reasonable."
"As with all Oracle products, care should be taken when using any features to ensure that they do not activate licensed features that have not been paid for."
"The license is good but can be improved."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
