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,…

A stable tool that provides users with a dashboard to give a view of all the implementations of Oracle products at a glance
When my company has to deal with complex customers along with the many products from Oracle, we use Oracle Enterprise Manager as a dashboard to get a view of all the implementations of Oracle products The fact that Oracle Enterprise Manager is an expensive solution is a matter of concern and…

Quotes from Members

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

Pros

"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 DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"Memory and CPU utilization features are good."
"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 a stable solution...The initial setup of Oracle Enterprise Manager was straightforward."
"The solution's most valuable feature is the ability to examine SQL code, track how many times it’s been parsed and used, and utilize this data for tuning."
"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."
"The job subsystem, monitoring subsystem, alerting, grouping of targets, and reporting features are valuable to us."
"Oracle Enterprise Manager is a scalable solution."
"The 13cR2 updates to the OEM family, strongly integrate Cloud (off-site, hybrid and on-premise) services providing a seamless way to see all of your resources regardless of where they are deployed."
"Due to the infrastructure's size, the introduction they offer is very, very useful. It helps with an overall understanding of the product."
"The dashboards are great for gathering analytic information and seeing where the problems are."
 

Cons

"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."
"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."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"Patching. It's extremely difficult to determine what requires patching and the process to patch each component is slightly different."
"The solution has a very large resource system. It's too big. There are too many items."
"The solution is considered expensive."
"The tool is expensive."
"Reporting and statistical charting is largely still left up the end-user to develop custom solutions."
"We would like to have a single dashboard for monitoring and controlling all of our products."
"In my opinion, rather than a younger DBA, think the user interface could be improved."
"The areas where Oracle Enterprise Manager could improve include the dashboarding, which could be made more intuitive, and the drill-down reporting, which can and should be enhanced."
 

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."
"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."
"The solution is free."
"The product’s price is reasonable."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"We are satisfied with the pricing."
"It's expensive."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
