Oracle Enterprise Manager Cloud Control Pros and Cons

Oracle Enterprise Manager Cloud Control Pros

Using Enterprise Manager, I was able to create user profiles for all the instances that have the same profile. Secondly, it's easier to manage performance, to automate the AWR reports to run every half an hour, or hour. Then, if you have a performance issue you just open the report and you can see what was running the last one hour, the SQL statements, or what was causing the performance issues.
Of course, that you can manage and create the backup strategies from a central environment for all your environments, so you don’t have to do so on each database. You can set up the policy you want for each database, but you do it from a central environment.

You can create a system group (database, application, and web server), so you can monitor performance as a system.
It is easier to manage your Oracle Database backups and create email alerts regarding the status of your backups (Succeeded or Failed).

One of the clearest examples is the agility of discovering processes/sessions that are burdening the database environment. With this agility, the DBA can more quickly verify this type of problem, in addition to checking locked sessions and not having to do several searches in views and tables of the data dictionary. The tool already does this for you in an agile way.
Another feature is the Resource Manager, where we can manage the consumption of resources of certain queries, separately in resource groups. Depending on the characteristics of the query, queries can be placed in groups that consume less database and hardware resources.

​The solution provides very useful insights for application and database performance tuning. We were able to do away with guess work in determining where the bottlenecks were in application performance.​
Advisors provide quick access to Insight and best practice information for performance tuning and configuration.

Oracle Enterprise Manager Cloud Control Cons

Because all our banking infrastructure is based on Oracle, I’ve tried to register Enterprise Manager on the middleware level, let's say, WebLogic applications. But I cannot say that I can do all the administration from Enterprise Manager, that I can do from the WebLogic Admin Console. So, I think here it needs some improvement: Things that you can do on the WebLogic Admin Console, you should be able to do them on the Enterprise Manager, so you don’t have to log into the Admin Console.
Sometimes the alerts are coming a bit late, for example, an alert for the CPU. It depends on the threshold that you have, how long you want to check the CPU of the machine. I got some faulty alerts with Data Guard. I had stopped a synchronization for maintenance and then I re-synchronized Oracle Data Guard. It took some time to appear in Enterprise Manager and send me the right notification that Data Guard was up and running and synchronizing. I realized this because I went directly into the database to check the status of Data Guard, and it was telling me that it was running okay. But in Enterprise Manager, it needed some more time to update the interface.

When registering a host, only if your host is running Linux will you get all the information which is available on EM. It would be nice if in future releases to include IBM AIX (primarily)​ and Microsoft Windows (secondly)​.
You cannot use Enterprise Manager as replacement for a WebLogic console.

One of the things that can be improved is the quality of results generated by BI Publisher. They are somewhat confusing when it comes to analysis.
The installation steps are very complex and the documentation for them is very generic and does not make very clear the correct steps from the installation to the addition of the host and database.
Another point that can be improved is the agent instability in the monitored hosts, because sometimes an agent has to be resynchronized to recapture the information.

​Oracle Data Guard monitoring: There are no alerts for redo log transport failure.​
