Use of return code in "ping" function

[antyale]

In the following sub, shouldn't it return ERROR at the end by default and just OK when it is OK for sure?

sub ping {
    my $self = shift;
    try {
        unless (defined $self->db()) {
            $self->_connect_db();
        }
        unless($self->db->do('delete from dod_dbmon.ping') == 1) {
            $self->log->debug('Problem deleting entry from ping table');
            $self->log->debug("Database seems UP but not responsive");
            return $ERROR;
        };
        unless($self->db->do('insert into dod_dbmon.ping values (curdate(), curtime())') == 1) {
            $self->log->debug('Problem inserting entry into ping table');
            $self->log->debug("Database seems UP but not responsive");
            return $ERROR;
        }
        $self->log->debug("Database is UP and responsive");
        return $OK;
    } catch {
        $self->log->error("Problem connecting to database. DB object:");
        $self->log->debug( Dumper $self->db() );
        return $ERROR;
    };
    return $OK;
}
