Mutual & Federal Insurance Company Limited Authorised Financial Services Provider ----- Hi, I am being pressured into changing users on some oracle servers with regards to DBA accounts. The client wants all these accounts to expire and some commonly known accounts to be locked. I have not yet tried to experiment with this and would like to know from the community before actually trying this. What if any are the implications of locking the SYS account? TIA Denham
