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

"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"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. It's basically the output of an sp_who2."
"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."
"Memory and CPU utilization features are good."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"The ability to go back and look at historical data is the most valuable feature."
"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 a number of different user interfaces you can choose from."
"I would recommend that you try OEM, it can monitor many different products and it has been well designed."
"Customer service has been consistently excellent."
"Can easily visualize bottlenecks in database performance tuning with historical graph trends; whereas before it would be based upon manually tuning using scripts which are text based."
"Can drastically reduce the diagnostic time and help monitoring multiple instances."
"One of the valuable features is performance drill down."
"It can also help with capacity planning, sizing, and maximizing overall performance in a large scale environment."
"We use it extensively for performance tuning testing, monitoring, and configuration."
 

Cons

"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"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."
"Some more granularity in alerting."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"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."
"Reporting and overall analysis of data gathered from SQL Server."
"The monitoring feature should be improved, so that it may be used as a dependable monitoring solution, as well as a deployment solution for SPARC-based hardware and operating systems."
"Technical support is good. That said, they take a lot of time before they start acting upon an issue."
"Sometimes it will take some time to open forms, so I feel it should be a little bit faster."
"One of the biggest issues, especially for 12c grid control, is the performance; to be able to monitor and find the root cause of performance issues immediately, in real time."
"Technical support could be more responsive."
"With any Oracle protocol, and Enterprise Manager is one of them, as far as the interface is concerned, it's not good and is still pretty ugly."
"The storage system monitoring is really a little basic. They just give the symptoms, not the solutions."
"It should be more scalable, because only for the database can we have the backup source standardized."
 

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 is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"The basic functions are free. You only pay license fees for advanced features."
"The licensing is the responsibility of our customers."
"The product is highly-priced."
"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."
"The product is very expensive."
