I am very new to Oracle so please understand that everything I have done for my Oracle database is my first time. I was given the task to manage a database while the DBA was out. I am not a DBA I'm a database analyst. My task was to refresh a schema I researched it and it was suggested to do a drop user cascade so I did a drop user cascade for a clean slate before doing an import schema. What I have noticed now when I compare the from and to schema is that the indexes on the designated schema do not match up to the number of indexes on the schema where the export file came from, a significant drop. I have also noticed that the security roles are missing a large number of objects that were assigned to them. Would the drop user cascade cause these things to occur? Thank you.

drop user will just drop the user / do a clean up in target area.
Anything associated with the user is gone.
>> do not match up to the number of indexes on the schema where the export file came from
Depends on how you did the export and import.
May be you excluded indexes/constraints that will create indexes.
You can always recreate the roles/privs from source.
