NAME

 hadbm clearhistory - clears the history files on the database

SYNOPSIS

 hadbm clearhistory [adminpassword=password | adminpasswordfile=filename] [saveto=path] [agent=ma_url] [dbname]

DESCRIPTION

Use the hadbm clearhistory command to clear the history files on the database. The directory to which the history files are to be saved must exist and must be writeable. The history file of the named database will be truncated. You can verify by checking the size of the history file. The database state remains unchanged. If a database is identified, it should already exist. If a database is not named, the default database history files are cleared. The default database is hadb.

In interactive mode, the hadbm clearhistory command prompts for a confirmation before clearing the history.
