Help! Level - 0 Archive / Informix Administrator unavailable!

Informix 7.12 Solaris ??? We have a small database residing on one volume for which we created a separate blob space (for Text columns) on the same volume - pretty basic stuff I guess. We were in the process of changing the database to use logging (it was not using logging before). The next step was to perform a level - 0 archive to activate the logging. Now the problem, Our Administrator had to leave unexpectedly due to an illness in the family. The level - 0 archive was never performed. I cannot find our copy of the Online Dynamic Server Administrator's Guide Vol. 1. I know what I need to do but I have no clue as to the syntax, etc. I would like to perform the level - 0 archive to a null device. (backups are not an issue for this database, it is being used to test an application that is behind schedule). Can anyone help please ??? Thanks, Bill
