Archiving Application Server Configuration Files
To track changes made to the psappsrv.cfg file and the history of the changes, a subdirectory, named "archive," stores various versions of the CFG file. You can find this subdirectory in the domain name directory, as in C:\PS_CFG_HOME\appserv\domain name\archive, where the current version of psappsrv.cfg resides.
When you boot the application server domain for the first time, PSADMIN places a copy of psappsrv.cfg in the archive directory. In subsequent boots, if PSADMIN detects a change in psappsrv.cfg based on the time stamp values, it replaces the current psappsrv.cfg with the latest version. The file name of the new version is then psappsrv_mmddyy_hhmm_ss.cfg, as displayed on the time stamp.
