Hi JavaPoet, and thank you for your answer.
Changing this installation path for RD&T is not mandatory for us, but in our site we have already stablished some rules and standars for our AIX systems, our first Linux is this one dedicated to RD&T, and we would like apply our Unix politics to this new Linux server.
One of this rules used for recovering from Back ups is that in /usr only could be installed software base and the rest of products must be installed in /opt, /var/opt , /user-HOME, etc..
This is the reason of my question.
I make different tests changing the path and using "links" to the new directory, but that did not work and other test, and of the problems was the eDMosa emulation, this connection emulation did not start...
For your comment I already know is not recommended changing this installation path, but somebody can give more detail about why this product needs /usr/z1090/bin as installation path, and why is not recommended change it?.
Thank you everybody.
