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."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"Memory and CPU utilization features are good."
"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."
"I think the look and feel and the accessibility to the databases, the scale of environment support."
"I would recommend learning and using OEM right away; it will cut down the time put in by DBAs a lot by using OEM."
"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."
"It is the best database management system."
"I have found the uptime of all of our systems to be most valuable with this solution. This is important because we need to guarantee specific uptime and preventive maintenance. We need to know upfront if there are going to be any issues on the database so we can proactively solve those."
"I think the neatest, most valuable feature of Enterprise Manager (OEM) is that single pane of glass for the whole stack, that it gives me as an admin the ability to look all the way up from my storage all the way up to the application tier."
"It allows me to manage resources effectively and monitor active sessions."
"If your database scalability is more or if your infrastructure is as big as the product we have, Oracle is the only solution out there."
 

Cons

"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."
"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."
"Reporting and overall analysis of data gathered from SQL Server."
"Some more granularity in alerting."
"It would helpful if SQL DM could mark when changes are made within the program."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"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."
"If it had more drill-down facilities, that would be great."
"The product is pretty comprehensive, but quite resource hungry. This might be due to the majority of the application seemingly being written in Java."
"We've had a lot of struggles patching automation. There's no good log file that you can debug."
"I would like to see better pricing."
"In a large organization with large number of targets, managing systems on an individual basis can be time consuming and difficult."
"The fact that Oracle Enterprise Manager is an expensive solution is a matter of concern and needs to be considered for improvement."
"I would like to see Oracle address the multi-data center monitoring and management in a more seamless way where management services are easily spread across the data centers like they can be today, but address the single database repository that can only exist in one data center at a time."
"Technical support is good. That said, they take a lot of time before they start acting upon an issue."
 

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."
"There is only the standard licensing fee. There are no other costs."
"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."
"The basic functions are free. You only pay license fees for advanced features."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"The license is good but can be improved."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
"The solution is inexpensive to purchase."
"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."
