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

"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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."
"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."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"Baselining our SQL Servers has made a huge impact."
"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."
"In my opinion, without Enterprise Manager no DBA can do their job."
"It is the most up-to-date tool as of now for monitoring, that's it."
"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"
"It is a scalable solution. So far, my company has not faced any issues with the scalability part of the solution."
"The tried and tested services that Oracle provides is second to none."
"Monitoring of the database is the most valuable feature, because we want to know what's going on there."
"We are going to minimize the downtime; if the system is down, it will page us and we are going to get to that issue, and it also tells us when the system is running slow so if some people are experiencing performance issues we can see that, and it is a very useful graphical user interface for the management to understand."
 

Cons

"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"Some more granularity in alerting."
"Reporting and overall analysis of data gathered from SQL Server."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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 like to see better pricing."
"The user interface is pretty clunky."
"One of the drawbacks that I don't like is, quite often you'll see that the agent will show a status of Pending."
"Sometimes it will take some time to open forms, so I feel it should be a little bit faster."
"Enterprise Manager is not easy or for the faint of heart. It is extremely robust, and hence very complicated to set up and maintain."
"The support is not good for this product. The enterprise system that I have is kind of complex."
"Setting up provisioning can be challenging. Also there are a lot of bugs and some specific to platforms."
"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."
 

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 pricing is very high."
"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."
"The license is good but can be improved."
"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’s price is reasonable."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
"The licensing is the responsibility of our customers."
"The solution is inexpensive to purchase."
