tuxedo 升级官方说明文档上说主要有两个升级，一个是停止应用后的升级，简单升级，一个是不停止应用的hot 升级

备份这些文件Backing Up Files
There are certain files that you need to back up prior to the installation and then restore after the installation is complete. Any modifications that you made to these files will be overwritten when the new Oracle Tuxedo software is installed.

To avoid having to modify these files again, follow these steps:

Back up the RM file to a temporary location. The RM file contains database vendor-specific settings that are used by commands such as buildtms and buildXAJS. It is located in the tux_prod_dir/udataobj directory, where tux_prod_dir is the directory in which you installed the Oracle Tuxedo or Oracle WebLogic Enterprise software.
Back up the tuxwsvr.ini and webgui.ini files to a temporary location. These files contain customized initialization settings for the Oracle Tuxedo Administration Console server and GUI. The tuxwsvr.ini file is located in the tux_prod_dir/udataobj directory, and the webgui.ini file is located in the tux_prod_dir/udataobj/webgui directory.
Back up the CATNAMES, jrepository, and jrly.config files. The CATNAMES file is located in the tux_prod_dir/locale directory. The jrepository and jrly.config files are located in the tux_prod_dir/udataobj/jolt directory structure.
Move any files that you or your coworkers added to the tux_prod_dir directory to a temporary location.
After the installation is complete, restore these files to their original locations.
