Oracle’s Enterprise Manager is an on-premises monitoring and management tool. The console is designed primarily to manage other Oracle products, it but can integrate to manage non-Oracle components as well.

SolarWinds Database Performance Analyzer (DPA) enables deep visibility into database performance and expert advice for performance optimization and tuning. What can you monitor with DPA? Oracle Oracle Exadata Oracle EBS Microsoft SQL Server Azure SQL Database Azure SQL Database Managed Instance MySQL DB2 SAP ASE Aurora MariaDB DPA monitors physical, virtual,…
I wish I had an option to give it a 9.5 :) OEM Cloud Control is very well suited if you have a system with multiple implementations of Oracle Database Enterprise Edition. If you are willing to pay for the huge license cost which is typical with Oracle, then you will love to use OEM Cloud Control to monitor your entire ERP solution including web servers, applications, network, storage, and physical servers. It is not worth the buck if your's is a small implementation. Your DBA's should be able to work without depending on OEM Cloud Control.
I believe that SolarWinds Database Performance Analyzer is a great choice for an organization that does not have a specific DBA or one that is still growing into the role. SolarWinds Database Performance Analyzer is filled with hints, tips, and explanations of the various readings and metrics. This is very useful to help understand what is happening and why, what it means, and what some potential solutions are towards remediating any issues. This is extremely valuable for our development team, allowing them to be more proactive with the queries they write in viewing how they perform and where bottlenecks might be.
Oracle Enterprise Manager is a "one stop shop" for all of our management needs. This is helpful because it minimizes the management of the management software itself. There are less upgrades and connectivity issues to handle. And there are "plug-ins" for additional products we use like Blue Medora's one for PostgreSQL.
Managing administrative jobs can be burdensome in a shop with dozens of servers and databases. OEM Cloud Control makes it easy since you can view all the jobs for all servers in one place. It is easy to filter on jobs with problems or the like so that you can quickly look at the logs and fix the issues.
Tuning PL/SQL is much easier using OEM Cloud Control. Most DBAs are familiar with trace files and TKPROF, but not having to do those things at a command line smooths the process out. The graphical interface makes it easier to show developers exactly what the issues are. This makes for less finger-pointing and quicker resolution of performance problems.
Proactive management is easier using OEM Cloud Control. Before having the gui, I had a collection of scripts that I would have to install on each database server, then set up cron jobs to run them. When Oracle was upgraded, those scripts might have to be updated on each and every server. OEM Cloud Control has those things built in. You can choose exactly which metrics are important to you. And you can keep performance graphs up all day on a second monitor to let you instantly see when something might cause a problem.
We also use OEM to monitor SQL Server. However, OEM only provided limited features for SQL Server. It would be nice if we can schedule backup jobs for SQL Server in OEM.
The ability to run SQL queries. You can't run queries in OEM. I have to go to SQL Developer or SQL PLUS to run. queries.
Resiliency of the Monitoring checks after the server underwent maintenance reboot. My experience is the monitor (Action) needs to be started manually. If possible it can automatically detect service/server then start to monitor again when system is back up.
We have relied on this product for a very long time and it continues to exceed expectations. The product is a vital part of our organization at this point, it would not be very ideal for us to abandon it. We use it almost every day and depend on its alerts for critical parts of our business
It's great! It does everything and anything you would want it to do. It can monitor things which doesn't comes out of the box by adding plug ins to it, for example, you can even monitor Oracle GoldenGate Replication by adding a plug-in to OEM Cloud Control.
I don't want to think about managing clusters of SQL servers in the future without this tool. We have demoed other tools and SolarWinds Database Performance Analyzer is the gold standard for usability and insight into what your servers are doing. The UI is a bit dated, but everything is laid out in a logical manner and drilling down into queries or timeslices is extremely intuitive.
I still rate OEM as a must-have tool for central management of Oracle fleet. The pros and cons of the product is prominent. Meanwhile, I also acknowledge that OEM was design about a decade ago. At that time, it did not have the landscape we have today, such as cloud, DEVOPS, machine learning, etc. I hope in future releases, the design will incorporate those features.
I have had to use their support on a few occasions, for reasons that I am not clear about until recently I have always had problems upgrading the software (although the last 2 updates have gone without issue which I am very pleased to say). On those unfortunate occasions, the support has been brilliant with either excellently documented guides on how to resolve the issue by myself or have been hands-on with calls and screen sharing to remotely fix the issue. Every time the problem was sorted and more importantly, nothing was lost (apart from a bit of time). And as I stated above whatever the problem was that was causing my upgrade issues appears to have been resolved in the last 2 updates.
Follow the guidelines for the capacity of the servers. We found that the DPA databases were getting rather large and also that there are ways to reduce their size built into some of the options.
Kibana from Elastic is another monitoring tool that claims to provide very similar information to OEM. It seems to be an information tool rather than a tool that can actually make changes within a database. I think Kibana is more robust for hardware versus database software so it is more suited to that purpose and does to compare to the Oracle Database monitoring attributes of OEM.
I have used Spotlight (for Oracle on RAC) but it has been several years. The dashboard was crisp, clean, and intuitive, but the tool had a significant overhead. However, no competitor made a tool that met our needs at the time. I have also used Idera's SQL Diagnostic Manager in more than one company. That tool is helpful for a larger environment than we currently have. But I think it is better at alerting than DPA but worse at just about everything else. The good thing is you can flag an alert as acknowledged, so you stop getting emails. The bad thing is I don't think I could use it to troubleshoot issues like I do with DPA. I do not have enough experience to provide helpful feedback on the others selected.
Positive: Alerting features. Without this we would have to be a 24x7 shop with someone always manning the helm. With the alerting feature we can define levels of alerts and only get the most pressing alerts sent out.
ROI: OEM is free, so the ROI is whatever you make of it.
Paid for itself in days. We had a stored procedure that could not meet its SLA, DPA highlighted the issue and contributed to the resolution.
We had a stored procedure that we were able to calculate as running in 9 milliseconds, unfortunately, we had transactions coming in 7 milliseconds, resulting in duplicate transactions, indicating that a mutex function was needed.
