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

"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."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"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 ability to go back and look at historical data is the most valuable feature."
"Memory and CPU utilization features are good."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"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."
"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."
"I think what I really like in this product is that DBAs and my management development team don’t have to sit and manually write queries."
"I like the reports of Enterprise Manager, as you have a lot of targets and can create generic reports based on some metrics of those targets, which allows me to have some sort of place to check all my targets."
"The 13cR2 updates to the OEM family, strongly integrate Cloud (off-site, hybrid and on-premise) services providing a seamless way to see all of your resources regardless of where they are deployed."
"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."
"It can also help with capacity planning, sizing, and maximizing overall performance in a large scale environment."
"What used to take hours to solve a problem can be done in a matter of minutes."
"The first reason we chose Oracle was the feature set; it was really comprehensive."
"My high rating reflects its ease of use and that it contains a host of features, anything and everything a database administrator would want it to perform; all the way from creating a database to adding space, to performance monitoring, to back up and recovery, to exports and imports, and security."
 

Cons

"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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."
"Some more granularity in alerting."
"Reporting and overall analysis of data gathered from SQL Server."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"I feel more dashboards can be added, especially those useful to higher levels of IT management."
"Costs of add-on’s and management packs i.e AWS (Amazon) and Golden Gate"
"It comes with some monitoring bugs, which once reported to Oracle support is always solved."
"RMAN tools need improvement."
"Some of the new features it could give us: maybe access to some of the taxation data and also some of the other benefits it could include as part of the system."
"It should be more scalable, because only for the database can we have the backup source standardized."
"One thing I would like to see is the option of agent less monitoring."
"The solution’s pricing could be improved."
 

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."
"It's expensive."
"The basic functions are free. You only pay license fees for advanced features."
"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."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"The product is very expensive."
"The product is highly-priced."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"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."
