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

"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."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"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 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."
"Memory and CPU utilization features are good."
"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"The masking features are good, and many new options and features are available in OEM for masking when compared to other tools."
"The most valuable features of Oracle Enterprise Manager are the data guide and online monitoring."
"We increased our capacity and speed of detection, diagnose and resolution of database issues."
"Can drastically reduce the diagnostic time and help monitoring multiple instances."
"I think it provides value for the money; it definitely helps us be proactive in our database administrating, because we don't have to spend time reacting to everything and can find out where the problem is before our customer even realizes they have a problem."
"We went with Oracle because we were looking for stability, a vendor that is reliable, being able to get help, troubleshooting when there's a problem."
"The best features are the usability and the interface."
"I would recommend Oracle Enterprise Manager to others."
 

Cons

"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."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"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."
"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."
"Enterprise Manager is not easy or for the faint of heart. It is extremely robust, and hence very complicated to set up and maintain."
"I would say mostly backup and recovery, through the Enterprise Manager. Or any corruptions, to be able to fix them through Enterprise Manager."
"There's a lot of documentation to go through as a new user."
"The issues we've had with Enterprise Manager go hand-in-hand with our issues with SOA Suite. There are performance issues that we see tied to SOA Suite and the B2B functioning, all of which impacts Enterprise Manager."
"Reporting and statistical charting is largely still left up the end-user to develop custom solutions."
"Services are pretty inconsistent. Too much usage will make it go down, and we will have to step in to bring it back up."
"It's very expensive."
"The user interface is not very interactive. It needs 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."
"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 product’s price is reasonable."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"The solution is inexpensive to purchase."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"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 pricing is very high."
