Using rs_init with resource files to install, configure, upgrade, or downgrade may save time if you plan to install multiple Replication Servers and many of the rs_init values are similar.
A resource file is an ASCII-formatted file that contains configuration information for rs_init. Instead of entering configuration variables during an interactive rs_init session, use any text editor to edit the resource file to specify the variables, then specify the resource file name on the rs_init command line.
