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,…

Performance issues have been identified and monitored effectively during peak hours
The weaknesses I would like to address in Oracle Enterprise Manager involve the dealing of Grid Infrastructure. Oracle Enterprise Manager's handling of Grid Infrastructure needs some improvement. I want to see additional features in the future that deal with security in relation to Oracle Grid Infrastructure. I want to improve these two components.

Quotes from Members

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

Pros

"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."
"The ability to go back and look at historical data is the most valuable feature."
"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."
"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."
"Baselining our SQL Servers has made a huge impact."
"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."
"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."
"It provides a graphical interface and easy management."
"My advice to others is Oracle Enterprise Manager is a stable and scalable enterprise compared to the other similar solutions."
"I think it provides value for the money; it definitely helps us be proactive in our database administrating, because we don't have to spend time reacting to everything and can find out where the problem is before our customer even realizes they have a problem."
"Oracle Enterprise Manager helps to control servers."
"I am happy with it; I think we are not leveraging it enough, but for what we use it for, it is perfect."
"We use Oracle Enterprise Manager for a lot of services like ERP and PLM."
"Initial installation of 12c OEM is convenient and straightforward."
"My company choose to use this product because I can see that it's going to be more aligned with the technology, with the cloud."
 

Cons

"Scalability is what I mentioned earlier, regarding room for improvement. It doesn't seem to scale out to an environment as large as ours, with just a single monitoring server."
"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."
"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."
"Some more granularity in alerting."
"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."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"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 solution is considered expensive."
"They should improve the hover text context. This would provide assistance whenever a task is attempted by a DBA."
"Oracle Enterprise Manager's scalability is an area with certain shortcomings where improvements are required."
"There are some monitoring tools, such as GoldenGate, that would be great if they could put them in OEM."
"Setting up the Oracle Enterprise Manager is challenging as it requires setting up a separate server."
"In my opinion, rather than a younger DBA, think the user interface could be improved."
"Technical support could be more responsive."
"I don't think it is that scalable. We are using multiple nodes, and we have faced issues there, with the scaling."
 

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's expensive."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"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."
"There is only the standard licensing fee. There are no other costs."
"We are satisfied with the pricing."
"Oracle Enterprise Manager is a free tool from Oracle."
"The product is highly-priced."
