Hi,
I have a doubt in locking user account in oracle database.
I was told to drop some unusable users in database which my clients dont require them.I verified the dependent objects of those users but not sure if these users can be dropped.
Instead can i make those user accounts locked so that they cannot connect to database ?
Would there be any impact on database performance if i lock those user accounts?
Is locking an account and dropping users is similar in anyway ?
Need your valuable input.
Thanks

When you lock an account, all you did is to restrict access to it. All its objects (tables, procedures, etc.) are still there (and accessible from other users, if privileges have been granted to them).
If you drop a user, all objects are also dropped.
If these users (that are no longer needed) are not related to other users (for example, their tables used in referential integrity constraints and similar), you might export these schemas, backup export files, and then drop users.

To put it another way - there is no way we can tell if dropping those users will cause issues.
It'll only cause issues if the users are being used by someone or something, but that you have to work out for yourself with proper analysis.

I take it you didn't bother doing this then:
