Jovery,

Can you help me out on this issue, I was trying to do backup of my database, the preferred credentials has been set. when i go TOOLS - DATABASES WIZARD - BACKUP MANAGEMENT and I click on BACKUP, am still getting this error

Using preferred credentials, the following error occured: ORA-01031: Insufficient priviledges

Thanks
