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

"SQL monitoring time has been dramatically reduced and our IT Infrastructure team has improved SQL maintenance and monitoring knowledge over time just by using SQL DM."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"The ability to go back and look at historical data is the most valuable feature."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"Baselining our SQL Servers has made a huge impact."
"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. It's basically the output of an sp_who2."
"OEM 12 C has simplified management of our Enterprise Systems and has eliminated unnecessary and legacy tools."
"One of the most valuable features of Oracle Enterprise Manager has been the preventive reporting capability."
"If your database scalability is more or if your infrastructure is as big as the product we have, Oracle is the only solution out there."
"The best part is the efficient database performance monitoring and the ability to take actions directly from there."
"If you run Oracle Products from Oracle OVM, Oracle Database, Web Logic, etc. Oracle Enterprise Manager is by far the best way to provide a single console and monitoring and alerting solution."
"This is one of the best tools we've had."
"The most valuable feature of the solution is that it is a very user-friendly tool."
"It's a very flexible, straightforward installation; it's user friendly, usable day by day and we can see the database monitoring, host monitoring, everything."
 

Cons

"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."
"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."
"Reporting and overall analysis of data gathered from SQL Server."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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."
"Some more granularity in alerting."
"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."
"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."
"I feel more dashboards can be added, especially those useful to higher levels of IT management."
"Every release, they seem to move the navigation and you have to retrain your entire DBA staff."
"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."
"Services are pretty inconsistent. Too much usage will make it go down, and we will have to step in to bring it back up."
"It's very expensive."
"One of the big problems we had was using Data Guard along with OEM; it just didn’t work (Data Guard is a local higher level solution). Every time we did a takeover, it would stop working, so that was the biggest challenge we had."
"The weaknesses I would like to address in Oracle Enterprise Manager involve the dealing of Grid Infrastructure."
"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."
 

Pricing and Cost Advice

"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."
"The pricing is reasonable, it's comparable with the competitors."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"The licensing is the responsibility of our customers."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"The basic functions are free. You only pay license fees for advanced features."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"The product is very expensive."
"It's expensive."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
