Automatic database checking and recovery: tcbck(ADM)

Automatic database checking and recovery: tcbck(ADM)

When the system is halted suddenly by power or hardware failures, some filesystem damage can occur. Such damage can result in the removal of security database files, or can leave these files in an interim state if they were being updated at the time of the system crash. Whenever a reboot occurs, the system runs a series of programs to check the status of the database files. When the system terminates abnormally and is rebooted, this check is performed after fsck(ADM) is run on the root filesystem, prior to entering multiuser mode. See ``Checking the security databases'' in the SCO OpenServer Handbook.


NOTE: tcbck(ADM) executes several checking utilities and even repairs certain inconsistencies (via authck), but does not execute integrity(ADM) or fixmog(ADM).
