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."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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."
"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."
"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 feature is the automation of the alerting, so we can be proactive when we use that program instead of being called in the middle of the night because something is wrong."
"The best part is the efficient database performance monitoring and the ability to take actions directly from there."
"My company choose to use this product because I can see that it's going to be more aligned with the technology, with the cloud."
"My high rating reflects its ease of use and that it contains a host of features, anything and everything a database administrator would want it to perform; all the way from creating a database to adding space, to performance monitoring, to back up and recovery, to exports and imports, and security."
"The best features are the usability and the interface."
"It is a must if you have more than a couple of databases to monitor and manage, it can also do a lot of other stuff and monitor various types of targets."
"Oracle Enterprise Manager triggers critical alerts."
"In my opinion, without Enterprise Manager no DBA can do their job."
 

Cons

"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."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"Reporting and overall analysis of data gathered from SQL Server."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"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."
"The tool is expensive."
"My opinion is that this solution needs to improve consolidation. That is what our business needs the most right now."
"For databases and servers with high blocking issues, the monitoring and graphs in OEM frequently became so overloaded that they could not be used and would not load, making OEM useless for troubleshooting certain production issues."
"Customer Service: 2 out of 5. I often choose to open an SR as a last resort."
"It could be faster; sometimes it takes a while to make the connection. Sometimes, it's complicated, too."
"If you see the documentation, it's not really that much good."
"It's very expensive."
"The fact that Oracle Enterprise Manager is an expensive solution is a matter of concern and needs to be considered for improvement."
 

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."
"It's expensive."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
"The product is highly-priced."
"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."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"We are satisfied with the pricing."
"There are a few bugs with the software which require opening SRs with Oracle Support which contribute to the day-to-day cost. Perhaps 8 hours per month is spent dealing with support, just as a rough guess."
