We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users.
We have been satisfied with technical support.
Once this solution is configured, it will help administrators centralize their management of the environment.
Oracle Enterprise Manager Cloud Control gives us diverse monitoring capability that can be extremely powerful.
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.
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.
They should add more features like object storage.
There is a lack from the point of view of monitoring on the system. The performance of the system and its resources are things that I think can be improved. There needs to be real-time monitoring available on the solution.
Because this solution provides insight into all of the areas within the IT stack, it would benefit from enhancements in security.
The product does have room for improvement in patch management.
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.
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.
Pricing and Cost Advice
VRA is very expensive but OpenNebula is free.
The licensing costs are largely too high.
We are using the free version. We are not using any licensed packages of Enterprise Manager, so I’m not quite sure how much each package is. As I understand it, there are different plug-ins that you need to buy for Enterprise Manager.
