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

"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."
"The ability to go back and look at historical data is the most valuable feature."
"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."
"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."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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."
"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."
"The most valuable features are security and speed."
"It's very insightful when it comes to what you can check healthwise on a database."
"The single-pane and single interface in the centralized system is the most valuable feature."
"Oracle Enterprise Manager helps to control servers."
"The masking features are good, and many new options and features are available in OEM for masking when compared to other tools."
"It allows me to manage resources effectively and monitor active sessions."
 

Cons

"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."
"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."
"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."
"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."
"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 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."
"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."
"Reporting and overall analysis of data gathered from SQL Server."
"The solution is considered expensive."
"I would like to improve the cost."
"We would like to have a single dashboard for monitoring and controlling all of our products."
"What I would love to see in Enterprise Manager is more support for the hardware, more support for Bare Metal."
"The only con is that we may need to install patches provided by Oracle from time to time for its upgrades or bug fixes."
"The solution’s stability could be improved."
"Every release, they seem to move the navigation and you have to retrain your entire DBA staff."
"The deployment is not straightforward."
 

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."
"The product is very expensive."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
"We are satisfied with the pricing."
"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."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"The product is highly-priced."
"The solution is inexpensive to purchase."
