If you installed the Oracle Tuxedo software on a UNIX system, Oracle strongly recommends that you create a separate user account for the Oracle Tuxedo administrator and give ownership of the Oracle Tuxedo files to that account. To change ownership of the Oracle Tuxedo software on a UNIX machine, enter the following command:

chown -R adm_account full_path_of_tux_prod_dir 
chgrp -R adm_group full_path_of_tux_prod_dir

Replace adm_account with the Oracle Tuxedo administrator account, replace adm_group with the Oracle Tuxedo administrator group ID, and replace full_path_of_tux_prod_dir with the full pathname of the product directory in which you installed the Oracle Tuxedo software.
