Since the mysql database is a critical component of the gateway, I would like for you to consult with your mysql DBA and give me a hard yes or no answer if this acceptable (I realize that the short term answer may likely be something along the lines of 'we cannot confirm, this will not be covered under your maintenance agreement, proceed at your own risk, and even if it works it may break with later patches, etc), which is fine. However, this may become a long term solution that allows for disk space maintenance of the mysql partition without incuring downtime, as the 'Shrinking MySQL ibdata file' disclaimer warns. Also, reading that procedure, I think I can perfrom it without incuring an outage... if it works I'll post it here so you can update that document.
