I have installed db2 10.1 on windows 8 but each time i am creating database it is generating
SQL1092N The requested command or operation failed because the user ID does not have the authority to perform the requested command or operation
but i have confirmed that user name by whom db2 is installed have proper administrative authority.
Note: I noticed one thing that in previous installation the user that installed automatically become the member of DB2ADMNS group but in my case there was no any group of name DB2ADMNS exist. for time being i have created a new group of DB2ADMNS but it also did not work.
