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

"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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."
"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."
"Memory and CPU utilization features are good."
"Overall, it has allowed us to do more with database management and run more databases on a given server, because we're able to isolate issues quicker and take the proactive steps necessary to correct them."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"I like the performance tuning features, particularly since it gives me a good glimpse of what has been happening."
"The solution is easy to use and has good performance."
"Technical support responds quickly."
"It is the best monitoring tool for Oracle databases; you have full visibility with the tool, it is a complete solution, and the software is simple to use."
"I think the look and feel and the accessibility to the databases, the scale of environment support."
"In my experience it seems the best tool for monitoring Oracle products, ranging from software to hardware like the engineered systems (e.g. Exadata)."
"Due to the infrastructure's size, the introduction they offer is very, very useful. It helps with an overall understanding of the product."
"I think what I really like in this product is that DBAs and my management development team don’t have to sit and manually write queries."
 

Cons

"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"Some more granularity in alerting."
"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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"Reporting and overall analysis of data gathered from SQL 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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"The product is pretty comprehensive, but quite resource hungry. This might be due to the majority of the application seemingly being written in Java."
"Improving the integration speed would be beneficial, as the current Java-based system can sometimes result in slow responses."
"It would be helpful if OEM is integrated with OBIEE reports and free report viewer without a license."
"Better mobile access would be useful."
"Customer Service: 2 out of 5. I often choose to open an SR as a last resort."
"The fact that Oracle Enterprise Manager is an expensive solution is a matter of concern and needs to be considered for improvement."
"We have experienced some downtime in terms of performance. For example, when we carry out some complicated code, it usually times out; sometimes it goes beyond sixty seconds and that's frustrating for the users."
"One of the drawbacks that I don't like is, quite often you'll see that the agent will show a status of Pending."
 

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 license is good but can be improved."
"The solution is free."
"As far as I know, you do not pay for Oracle Enterprise Manager separately. You can use Enterprise Manager for free if you already have an Oracle license for your database."
"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."
"We are satisfied with the pricing."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"The product’s price is reasonable."
"The product is very expensive."
