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

"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"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."
"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 ability to go back and look at historical data is the most valuable feature."
"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 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."
"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"You can get a healthful overview of all your targets in one snapshot in Enterprise Manager."
"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."
"The ability to scale is excellent."
"Oracle Enterprise Manager helps me investigate and extract what the issue is, rather than just observing the Oracle environment."
"SQL Tuning Advisor, ADDM, Top Activity, ASM Space Manager, Incident Notifications"
"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."
"We use Oracle Enterprise Manager as a tool to monitor Oracle products."
"I have found the singular GUI feature very helpful. Fewer DBA resources can be allocated with Toad licenses."
 

Cons

"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"Some more granularity in alerting."
"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."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"Reporting and overall analysis of data gathered from SQL Server."
"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."
"We did have some hiccups in working with Oracle."
"Enterprise Manager is not easy or for the faint of heart. It is extremely robust, and hence very complicated to set up and maintain."
"When contacting My Oracle Support, I encounter first-line support initially, which is inadequate as I require more in-depth support."
"I would say the footprint on the server. Also the GUI can be tricky."
"The product must improve its support team."
"I would say mostly backup and recovery, through the Enterprise Manager. Or any corruptions, to be able to fix them through Enterprise Manager."
"Middleware (weblogic) has some bugs and crashes occur which should be fixed to make OEM more productive."
"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."
"There is only the standard licensing fee. There are no other costs."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"It's expensive."
"The licensing is the responsibility of our customers."
"Oracle Enterprise Manager is a free tool from Oracle."
"The solution is free."
