Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
Backup and restore configuration parameter reference
Backup and restore configuration parametersThese topics describe the configuration parameters that you use with the ON-Bar, ontape, and archecker utilities.
The archecker utility configuration parameters and environment variableThese topics describe the AC_CONFIG environment variable and the configuration parameters that you use with the archecker utility.
AC_CONFIG file environment variableSet the AC_CONFIG environment variable to the full path name for the archecker configuration file (either ac_config.std or user defined).

AC_CONFIG file environment variable

Set the AC_CONFIG environment variable to the full path name for the archecker configuration file (either ac_config.std or user defined).

default value: UNIX™: $INFORMIXDIR/etc/ac_config.std; Windows™: %INFORMIXDIR%\etc\ac_config.std

takes effect: When ON-Bar starts

The following are examples of valid AC_CONFIG path names:

UNIX: /usr/dbserver/etc/ac_config.std and /usr/local/my_ac_config.std
Windows: c:\dbserver\etc\ac_config.std and c:\dbserver\etc\my_ac_config.std

If AC_CONFIG is not set, the archecker utility sets the default location for the archecker configuration file to $INFORMIXDIR/etc/ac_config.std on UNIX or %INFORMIXDIR%\etc\ac_config.std on Windows.

Important: If you do not specify the entire path, including the configuration file name in the AC_CONFIG file, the archecker utility might not work correctly.
