Audit Configuration and the ADTCFG File

Configuration parameters in the ADTCFG file specify the properties of the audit configuration. For UNIX, and Windows, these configuration parameters are ADTERR, ADTMODE, ADTPATH, and ADTSIZE. For Extended Parallel Server, an additional UNIX parameter, ADTADMMODE, specifies whether to audit certain utility program events.

The pathname for the ADTCFG file follows.

ADTCFG Pathname

UNIX

$INFORMIXDIR/aaodir/adtcfg

Windows

%INFORMIXDIR%\aaodir\adtcfg

If you edit the ADTCFG file to change the audit parameters, the audit configuration is not changed until you reinitialize shared memory. If you use the onaudit utility to change the audit configuration, the changes occur immediately.

Changes made with onaudit are written to an adtcfg.servernum companion file. (SERVERNUM is a parameter in the ONCONFIG file, which the IBM Informix: Administrator's Reference describes). An audit administrator must manually copy the changes from the adtcfg.servernum file to the ADTCFG file. The intent is to make it harder for the DBSA to start an instance of the database server with invalid audit parameters. For details on how to use the onaudit utility to configure the ADTCFG file, see Utility Syntax.
