Real-time monitoring we can quickly find the session or queries that are causing issues.
Improvements to My Organization:
With our different platforms running our databases like UNIX, Linux and Windows it becomes difficult to support manually with different type of scripts. With different types of database versions like 9i, 10g and 11g it helps to have one tool that can support them all.
Room for Improvement:
One thing I would like to see is the option of agent less monitoring. I would also like to see monitoring only at LDOM level so if you are using Solaris zones you only monitor at LDOM level.
Use of Solution:
I've been using OEM since version 10g which would have been since 2007.
The setup is straightforward the installer guides you during the installation. The installer also has pre-checks to make sure your system is ready for installation or upgrade. For upgrades you have the option of a 2 step system for if you want to move to another server and OS at the time of your upgrade from older versions.
I would recommend that you try OEM, it can monitor many different products and it has been well designed. When monitoring database performance in real-time I have yet to see another product that can do it as well as OEM.
Disclosure: I am a real user, and this review is based on my own experience and opinions.
