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,…

Extensive functionality impresses despite occasional setup complexity
The functions and features of Oracle Enterprise Manager that I have found most valuable are its evolution from being problematic in 10g and 11g versions to becoming better and more stable. Now it has become a significantly improved product. We have integrated identity management, and we are using it for normal database examination, tuning, and performance. We are working with STATSPACK and similar tools that are integrated in Oracle Enterprise Manager. We are currently working with version 13.5, having upgraded from 13.4 last year. Automation is useful for improving operational efficiency, and there are many more opportunities to automate outside the databases. Not many things need to be automated inside the databases. We have jobs running, imports, exports, and similar tasks. To automate these processes, we utilize the Scheduler from Oracle, which is managed in the databases by the vendor. This is not part of our DBA functions in Oracle Enterprise Manager.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"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."
"The ability to go back and look at historical data is the most valuable feature."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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."
"We are able to manage larger numbers of databases with less human resources."
"The best part is the efficient database performance monitoring and the ability to take actions directly from there."
"The single-pane and single interface in the centralized system is the most valuable feature."
"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 feature is that it is very easy for the novice DBA to drill down and find problems that might otherwise be difficult to find."
"It's a useful feature to be able to see the top SQL, the number of executions, the CPU, and the resources that it's using."
"It is the most up-to-date tool as of now for monitoring, that's it."
"The functions and features of Oracle Enterprise Manager that I have found most valuable are its evolution from being problematic in 10g and 11g versions to becoming better and more stable."
 

Cons

"Some more granularity in alerting."
"Reporting and overall analysis of data gathered from SQL Server."
"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."
"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."
"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."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"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."
"Oracle Enterprise Manager could improve the monitoring types and the graphics."
"Easier to read. For example, on the home page of information, under Adm, that should be a little bit easier to read."
"The areas where Oracle Enterprise Manager could improve include the dashboarding, which could be made more intuitive, and the drill-down reporting, which can and should be enhanced."
"I would like to see more functionality/information in Standard Edition Oracle for the same performance analysis."
"The solution has a very large resource system. It's too big. There are too many items."
"Sometimes the solution can be quite difficult in terms of when you want to deploy agents."
"The user interface is not very interactive. It needs improvement."
"There are a lot of options; it takes time. I don't see anything like a dashboard or something similar."
 

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 product is highly-priced."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"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."
"We are satisfied with the pricing."
"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."
"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 basic functions are free. You only pay license fees for advanced features."
