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

"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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 ability to go back and look at historical data is the most valuable feature."
"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."
"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 feature of the solution is that it is a very user-friendly tool."
"The biggest benefit of using Oracle Enterprise Manager is its monitoring capability."
"The most valuable feature is high availability."
"The most valuable feature is the monitoring because it's very useful for checking and troubleshooting compared with other products, like Nagios for example, that have some interaction with Oracle."
"With ASH Analytics, ADDM, Real-Time SQL Monitoring, SQL Tuning Advisor, we can measure SLAs, detect performance hotspots, perform deep diagnostics into specific tiers, tune applications, and remediate."
"It's easy to implement as it's made by Oracle for Oracle."
"Oracle Enterprise Manager has eased the responsibilities among our DBAs. We can now assign individual tasks to separate DBAs."
"It is a scalable solution. So far, my company has not faced any issues with the scalability part of the solution."
 

Cons

"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"Patching. It's extremely difficult to determine what requires patching and the process to patch each component is slightly different."
"Technical support could be more responsive."
"The tool is expensive."
"The product must improve its support team."
"I feel more dashboards can be added, especially those useful to higher levels of IT management."
"Reporting and statistical charting is largely still left up the end-user to develop custom solutions."
"I rate Oracle Enterprise Manager six out of 10 for affordability. It's expensive."
"We could use it but definitely with some effort we can streamline much better and sometimes some box here and there, like 13C you have to really wait, but there are great features. Just have to make sure it is a stable product."
 

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 solution is free."
"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."
"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."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
"The pricing is very high."
"The product’s price is reasonable."
