It is very easy to use,it can help me troubleshooting database issues as well provide recommendations for changes or upgrades that will improve performance of my application/database server etc!It's free version has limited features but you do get what u need without paying any money!! I have been using it since last 5 years with different clients in various industries such as manufacturing industry which are mostly DB2 servers running IBM iSeries OS (AS400) applications like MVS-RPGLE & COBOL programs; also we were solving some problems related business logic by writing custom scripts written in C++ language - this was quite difficult task at times because AS 400 does not support natively cpp compiler unlike other platforms so had no choice than write our own code from scratch instead of relying on existing libraries available within system itself!!
