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

"Baselining our SQL Servers has made a huge impact."
"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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 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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"Memory and CPU utilization features are good."
"If you run Oracle Products from Oracle OVM, Oracle Database, Web Logic, etc. Oracle Enterprise Manager is by far the best way to provide a single console and monitoring and alerting solution."
"The biggest bang for our buck with Enterprise Manger is automated patching."
"The single-pane and single interface in the centralized system is the most valuable feature."
"It's a very flexible, straightforward installation; it's user friendly, usable day by day and we can see the database monitoring, host monitoring, everything."
"I have found the singular GUI feature very helpful. Fewer DBA resources can be allocated with Toad licenses."
"One of the valuable features is performance drill down."
"I think what I really like in this product is that DBAs and my management development team don’t have to sit and manually write queries."
"From my experience, I'd say that the most valuable feature is the ability to manage all the databases, hardware, and middleware from one pane of glass."
 

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."
"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."
"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."
"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."
"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."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"I would like to have more details and privileges. I would say more grantable and obtainable privileges are needed."
"OEM needs to be a little bit faster."
"I have been using OEM 13c which is their latest release and I would have expected that the product would have been more stable and should not have bugs for very simple things like CPU utilisation or amount of physical memory on Linux hosts."
"I would like to see more functionality/information in Standard Edition Oracle for the same performance analysis."
"One thing I would like to see is the option of agent less monitoring."
"We use it mostly for the connection to the databases. It could be the version I'm on, but we seem a little limited on what we can do for monitoring for the middleware."
"It could be faster; sometimes it takes a while to make the connection. Sometimes, it's complicated, too."
"The product must improve its support team."
 

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 licensing is the responsibility of our customers."
"The solution is free."
"The solution is inexpensive to purchase."
"The pricing is very high."
"There is only the standard licensing fee. There are no other costs."
"We are satisfied with the pricing."
"The product’s price is reasonable."
"The license is good but can be improved."
