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,…

Monitors databases and applications efficiently with timely alerts
The most valuable features are the monitoring capabilities and how it provides time-to-time alerts, which are very beneficial. It is particularly helpful in providing alerts for tablespace issues or when databases or applications cross certain thresholds. The tool allows us to monitor 24/7, configure dashboards, and quickly check the status of databases that are in critical states. This saves time and enhances productivity.

Quotes from Members

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

Pros

"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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 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."
"The ability to go back and look at historical data is the most valuable feature."
"Memory and CPU utilization features are good."
"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. It's basically the output of an sp_who2."
"The job subsystem, monitoring subsystem, alerting, grouping of targets, and reporting features are valuable to us."
"The 13cR2 updates to the OEM family, strongly integrate Cloud (off-site, hybrid and on-premise) services providing a seamless way to see all of your resources regardless of where they are deployed."
"Oracle Enterprise Manager helps me investigate and extract what the issue is, rather than just observing the Oracle environment."
"It is a good tool for monitoring databases."
"It is the best monitoring tool for Oracle databases."
"The product gives us as much control as we can have by providing a complete picture of the whole set of Oracle products."
"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."
"It can also help with capacity planning, sizing, and maximizing overall performance in a large scale environment."
 

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."
"It would helpful if SQL DM could mark when changes are made within the program."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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 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."
"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."
"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."
"Technical support could be more responsive."
"The tool is expensive."
"They should improve the hover text context. This would provide assistance whenever a task is attempted by a DBA."
"My opinion is that this solution needs to improve consolidation. That is what our business needs the most right now."
"The platform's interface could be more streamlined. Currently, there are multiple ways to navigate to a specific point, which can be confusing."
"Better mobile access would be useful."
"In my opinion, rather than a younger DBA, think the user interface could be improved."
"The product is pretty comprehensive, but quite resource hungry. This might be due to the majority of the application seemingly being written in Java."
 

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."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"The solution is inexpensive to purchase."
"The basic functions are free. You only pay license fees for advanced features."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
"Oracle Enterprise Manager is a free tool from Oracle."
"The pricing is very high."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
