The archecker utility configuration parameters and environment variable

These topics describe the AC_CONFIG environment variable and the configuration parameters that you use with the archecker utility.

The archecker utility uses the configuration parameters in the ac_config.std template to verify a backup or perform a table-level restore. If you need to change these parameters, copy the ac_config.std template to the AC_CONFIG file. The AC_CONFIG environment variable specifies the location of the AC_CONFIG file.

Because ON-Bar calls the archecker utility to verify backups, you must configure the archecker environment variable and parameters before you can use the onbar -v option.

You can also use other archecker configuration parameters that do not have default have default values in the ac_config.std file, but are valid in that file.

Table 1. Configuration parameters that the **archecker** utility uses
Configuration parameter	Description
AC_DBSPACES	A comma separated list of dbspaces to scan.
AC_DEBUG	Prints debugging messages in the archecker message log.
AC_IXBAR	Specifies the path name to the IXBAR file. If not set in the ac_config file, the value of the BAR_IXBAR_PATH configuration parameter is used.
AC_MSGPATH	Specifies the location of the archecker message log. This configuration parameter is in the default ac_config file.
AC_SCHEMA	Specifies the path name to the archecker schema command file.
AC_STORAGE	Specifies the location of the temporary files that archecker builds. This configuration parameter is in the default ac_config file.
AC_TIMEOUT	Specifies the timeout value for the onbar and the archecker processes if one of them exits prematurely.
AC_VERBOSE	Specifies either verbose or terse mode for archecker messages. This configuration parameter is in the default ac_config file.
BAR_BSALIB_PATH	Identical to the BAR_BSALIB_PATH server configuration parameter that is in the onconfig.std file. For more information, see BAR_BSALIB_PATH configuration parameter.
