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

"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"The ability to go back and look at historical data is the most valuable feature."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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."
"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."
"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."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"Oracle Enterprise Manager provides complete, integrated solutions to achieve the level of business service quality required of enterprise applications, tools for managing configuration, performance and availability, and when combined with other management packs and plug-ins, it provides the means to achieve end-to-end management of the entire application infrastructure."
"It allows me to manage resources effectively and monitor active sessions."
"For Oracle databases and Oracle products in general, OEM is the best monitoring / console solution to get live and historical overview on your systems"
"The most valuable features are security and speed."
"The most valuable features of Oracle Enterprise Manager are the data guide and online monitoring."
"It is a good tool for monitoring databases."
"The look and feel I think. Fast and compatible."
"It is the best monitoring tool for Oracle databases."
 

Cons

"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"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."
"Some more granularity in alerting."
"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."
"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."
"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."
"We have experienced some downtime in terms of performance. For example, when we carry out some complicated code, it usually times out; sometimes it goes beyond sixty seconds and that's frustrating for the users."
"The one area was the process of setting up targets and hosts as it seems rather lengthy and repetitive."
"The technical support is not always 100% up to the mark or sometimes not as we expect it to be."
"It can be a process hog sometimes."
"The user interface is pretty clunky."
"The solution has a very large resource system. It's too big. There are too many items."
"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."
"BI Publisher integration; EM CLI commands."
 

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 product is highly-priced."
"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."
"The pricing is very high."
"The product is very expensive."
"The licensing is the responsibility of our customers."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"I rate Oracle Enterprise Manager’s pricing a five out of ten."
"The license is good but can be improved."
