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

"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."
"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."
"The ability to go back and look at historical data is the most valuable feature."
"Memory and CPU utilization features are good."
"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."
"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."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"The solution's most valuable aspect is the fact that it is embedded with the Oracle database and Oracle's engineering system, its extra data, and analytics."
"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."
"I think the fact that I can manage all of our infrastructure, all the hardware and software, from one place which makes it very useful."
"It's the most reliable database available on the market."
"Query tuning, historical graphs, real time statistics on query usage, easy to find blocking or locking queries, easy to kill queries, easy to add new datafiles to tablespaces about to run out of space, easy to explore table structure."
"We use Oracle Enterprise Manager as a tool to monitor Oracle products."
"We need 99.9995 uptime, and Oracle Enterprise Manager helps us to achieve this goal with its superior monitoring and management capabilities."
"Oracle Enterprise Manager is a scalable solution."
 

Cons

"Reporting and overall analysis of data gathered from SQL 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."
"Some more granularity in alerting."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"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."
"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."
"I think with the documentation there could be improvements."
"RMAN tools need improvement."
"In a large organization with large number of targets, managing systems on an individual basis can be time consuming and difficult."
"Technical support is good. That said, they take a lot of time before they start acting upon an issue."
"The solution’s pricing could be improved."
"There are some monitoring tools, such as GoldenGate, that would be great if they could put them in OEM."
"I have been using OEM 13c which is their latest release and I would have expected that the product would have been more stable and should not have bugs for very simple things like CPU utilisation or amount of physical memory on Linux hosts."
"Middleware (weblogic) has some bugs and crashes occur which should be fixed to make OEM more productive."
 

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."
"The basic functions are free. You only pay license fees for advanced features."
"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 product’s price is reasonable."
"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."
"Based upon 3 days of implementation by a single person, plus licensing costs would be approximately $60,000, including the virtualized hosts."
"The pricing is very high."
"The product is very expensive."
"There is only the standard licensing fee. There are no other costs."
