Help: Can't Find bcheck in V6.0

A few days ago, somebody has posted an article which said that the following command can unlock a locked table safely: bcheck -y <TABLE> However, when we tried to execute the command under our HP9000 S800 machine with Informix On-line v6.0 installed, it returns "bcheck: not found". Could someone on the net answer some of my questions below: 1. Exactly what functions does bcheck perform? 2. Does it comes with Informix? If yes, then which version? 3. If bcheck does not come with Informix, then how can I get one? Thanks in advance. -------------- Toh Hong Chuan bcsis@technet.sg
