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 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."
"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 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."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"Baselining our SQL Servers has made a huge impact."
"Oracle Enterprise Manager has eased the responsibilities among our DBAs. We can now assign individual tasks to separate DBAs."
"The product gives us as much control as we can have by providing a complete picture of the whole set of Oracle products."
"Initial installation of 12c OEM is convenient and straightforward."
"Oracle Enterprise Manager 12c is a transformational technology that comes with a set of comprehensive features and great practices that help IT transform into a true enterprise Cloud that delivers on business needs."
"The look and feel I think. Fast and compatible."
"Using this product, we have improved our process for generating revenue and sending out invoices to our customers."
"In fact, I've already met many people in which I have done just that."
"Oracle Enterprise Manager provides a single pane of control that gives you the visibility to see all Oracle products, plus the non-Oracle products; hardware, software, middleware."
 

Cons

"Reporting and overall analysis of data gathered from SQL Server."
"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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"OEM needs to be a little bit faster."
"The one area was the process of setting up targets and hosts as it seems rather lengthy and repetitive."
"There are a lot of options; it takes time. I don't see anything like a dashboard or something similar."
"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."
"One of the biggest issues, especially for 12c grid control, is the performance; to be able to monitor and find the root cause of performance issues immediately, in real time."
"I would probably like to see more plug-ins to manage even more heterogeneous types of resources."
"The deployment is not straightforward."
"Services are pretty inconsistent. Too much usage will make it go down, and we will have to step in to bring it back up."
 

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."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"Oracle Enterprise Manager is a free tool from Oracle."
"The licensing is the responsibility of our customers."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"The product’s price is reasonable."
