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,…

Quotes from Members

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

Pros

"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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."
"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."
"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 tried and tested services that Oracle provides is second to none."
"The dashboards are great for gathering analytic information and seeing where the problems are."
"We can manage everything in our environment."
"It is a stable solution...The initial setup of Oracle Enterprise Manager was straightforward."
"I have found the singular GUI feature very helpful. Fewer DBA resources can be allocated with Toad licenses."
"The job subsystem, monitoring subsystem, alerting, grouping of targets, and reporting features are valuable to us."
"It can also help with capacity planning, sizing, and maximizing overall performance in a large scale environment."
"SQL Tuning Advisor, ADDM, Top Activity, ASM Space Manager, Incident Notifications"
 

Cons

"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."
"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."
"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 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."
"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."
"When contacting My Oracle Support, I encounter first-line support initially, which is inadequate as I require more in-depth support."
"There's a lot of documentation to go through as a new user."
"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."
"We have encountered performance issues when the load is huge."
"My opinion is that this solution needs to improve consolidation. That is what our business needs the most right now."
"The solution has a very large resource system. It's too big. There are too many items."
"Oracle Enterprise Manager's scalability is an area with certain shortcomings where improvements are required."
 

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 basic functions are free. You only pay license fees for advanced features."
"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."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"The licensing is the responsibility of our customers."
"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."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"The pricing is very high."
"It's expensive."
