ovdb_recover

ovdb_recover(8) 					    InterNetNews Documentation						   ovdb_recover(8)

NAME

       ovdb_recover - Perform recovery on the ovdb database, if needed

SYNOPSYS

       ovdb_recover [-f]

DESCRIPTION

       Attempts to open the ovdb database, and if the database needs recovery, it attempts to perform the recovery.  Similar in function to the
       BerkeleyDB db_recover command.

       Specify the `-f' option to force a recovery, even if the database appears to not need it.  It is not an error to perform a recovery opera-
       tion on a clean database.  However, do not run `ovdb_recover -f' while the database is in use by any other processes.

       Returns exit status of 0 if the database did not need recovery or if recovery succeeded, and returns exit status 1 if recovery failed.  In
       the latter case, the database may be damaged beyond repair, requiring a rebuild with makehistory(8).

       This command is normally called automatically by rc.news(8).

HISTORY

       Written by Heath Kehoe <hakehoe@avalon.net> for InterNetNews.
