LTXHWM is the Long Transactio High Water Mark - set to 75% which tells online to roll transactions back when the logs are 75% full. LTEXHWM is the Long Transaction Exclusive High Water Mark - set to a value > LTXHWM, usually 80% , which when reached, gives "exclusive" access of the logical logs to the transaction currently being rolled back. just a brief explanation but i hope it helps. regards, ramesh. > >======================================================================== >Bharat Shah Voice: (508)-663-7570 >Unifi Communications Corp.
