Retry with a different user name
If i create with a different user, i worry my database can't use with my backup data.
because instance user as possible same with the user database from the production database, except i use database with different name, i can use restore into different name database.
Actually i want create with the user exists on the system for DB2 instance.
If you want create instance with user exists on SuSe 10 Enterprise,
and i try to delete that exist user before create instance, after than i can create Instance user from DB2. I already try this and the result is good.
