Need to lock the users user accounts in bulk

Content

Hello Oracle Experts,

We want to lock the user accounts in bulk at once. I checked the Business Object - User (User.dat file) but there is no attribute to lock the user account. Is there any HDL file or anything which we can use to lock the accounts at once? If yes, the appreciate it if shared.

Thanks and Regards,

JD
