Loading the System
Configuration File
Normally, you select Current (CONFIG), the default system configuration file. For the
system disk volume you select to load the system, CONFIG represents the system
configuration database that is currently running or was last running.
If you cannot load the system using Current (CONFIG), you might need to use these
files to recover:
•
Saved Version (CONFxxyy) is a saved system configuration file. Use this file to
recover from a configuration change that causes a problem. If you cannot load the
system using the CONFIG file, you can use a saved version in the form xx.yy, if
one is available. For example, the CONF0205 file would be specified as 02.05.
Use this method to recover from a configuration change that caused a problem
(such as a system freeze). When the system starts and displays a TACL prompt,
you can log on and start the rest of the system applications.
•
Base (CONFBASE) is the most basic configuration required for system startup.
Although you will probably never need to load the system from the CONFBASE
file, you might need to use this file if you cannot load the system using any other
method.
For more information about when to use CONFSAVE or CONFBASE, see Recovering
From a System Load Failure on page 15-20
