Dear Bernard
I have changed the password using brtools. I have also read the note 50088. There are a zip file attached to this note. Please let us know that can we run those zip file (*.sql) on sqlplus system/manager and it will create the OPS$ users.
Otherwise request you to send the procedure for the same .
My old system hostname is :KTMHOECQAS
New system hostname is : KTMHOECCDRTEST
