If rollback logging is enabled using DFSETUP, this utility recovers a database after a system crash. It is usual to arrange for DBRECOV to be run automatically as part of the startup for a DP4 system, so that end users do not have to run this program for themselves.
See Recovering a Database in the DP4 Developer's Manual for further information about this program.
