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."
"Memory and CPU utilization features are good."
"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 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 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."
"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."
"It is the best database management system."
"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."
"The solution is easy to use and has good performance."
"I mostly use the top events, and look at how the execution is happening on the database; and monitoring the cluster level rates. I even look at the execution plan."
"What I like most about Oracle Enterprise Manager are its features, particularly the active session history. It provides insights into SQL, and I use it regularly to identify potential issues."
"It allows me to manage resources effectively and monitor active sessions."
"It's a useful feature to be able to see the top SQL, the number of executions, the CPU, and the resources that it's using."
"One of the most valuable features of Oracle Enterprise Manager has been the preventive reporting capability."
 

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."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"The weaknesses I would like to address in Oracle Enterprise Manager involve the dealing of Grid Infrastructure."
"There are limited numbers of other OEM devices that can be integrated into enterprise management that can be scaled by Oracle by adding other OEM devices to enterprise management."
"The solution’s pricing could be improved."
"The product must improve its support team."
"The interface offered by Oracle Enterprise Manager has certain shortcomings and needs improvement to become a nice tool."
"The platform's interface could be more streamlined. Currently, there are multiple ways to navigate to a specific point, which can be confusing."
"Improving the integration speed would be beneficial, as the current Java-based system can sometimes result in slow responses."
"It needs to support the Database versions lower than 10.2."
 

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."
"The product is highly-priced."
"The product is very expensive."
"The license is good but can be improved."
"Oracle Enterprise Manager is a free tool from Oracle."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"There is only the standard licensing fee. There are no other costs."
"The pricing is very high."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
