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

"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."
"One of the things that it is used for is to detect anything that could possibly cause our systems not to function well, and it has helped us to determine that before anything has actually happened."
"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."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"I have found the singular GUI feature very helpful. Fewer DBA resources can be allocated with Toad licenses."
"It's the most reliable database available on the market."
"The most valuable feature of the solution is that it is a very user-friendly tool."
"The product gives us as much control as we can have by providing a complete picture of the whole set of Oracle products."
"I would recommend Oracle Enterprise Manager to others."
"We can manage everything in our environment."
"Technical support responds quickly."
"The most valuable feature is high availability."
 

Cons

"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 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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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."
"Some more granularity in alerting."
"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."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"It would helpful if SQL DM could mark when changes are made within the program."
"I don't think anybody can walk on water. Software is buggy and that's the nature of the beast."
"What I would love to see in Enterprise Manager is more support for the hardware, more support for Bare Metal."
"It is mostly stable, but we have found some issues when we are having resource contention or CPU issues."
"For databases and servers with high blocking issues, the monitoring and graphs in OEM frequently became so overloaded that they could not be used and would not load, making OEM useless for troubleshooting certain production issues."
"It could be faster; sometimes it takes a while to make the connection. Sometimes, it's complicated, too."
"The support is not good for this product. The enterprise system that I have is kind of complex."
"When contacting My Oracle Support, I encounter first-line support initially, which is inadequate as I require more in-depth support."
"The solution’s stability could be improved."
 

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 pricing is very high."
"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."
"The product is very expensive."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
"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."
"There is only the standard licensing fee. There are no other costs."
"The licensing is the responsibility of our customers."
