This little project is proving to be a bit more challenging than I had anticipated. There doesn't seem to be a single process that gives me what I need.
GS's suggestion to use the "Create Like" in the em GUI is intriguing. It does include the grants. It's quite tedious for several hundred users, however.
Noons' suggestion to list out the dump file made with full=y from source database is likewise, very useful. I can get user creates and grants from that. The listing doesn't come out in a "usable" script format, so there is lots of editing to do.
To simply create a script to create the users, the easiest method seems to be simply spool a select username and password from dba_users. That, of course, doesn't help with the grants.
All in all, it has been a learning experience for me. Thanks to all who offered suggestions. Users expect to go live in the new database on Monday. Received on Sat Jun 14 2008 - 11:06:41 CDT
