If you plan to install multiple Replication Servers, and many of the rs_init values are similar, using resource files to install, configure, upgrade, or downgrade may save time. See Appendix B, “Using rs_init with Resource Files” for more information.
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, you edit the resource file to contain the variables, then type that file name on the rs_init command line.
