Oracle DB restore needs

I remember to do few post db restorations steps on SQL server while migrating DB back from one server to other. For example see below:

EXECsp_change_users_login'Report'
EXECsp_change_users_login'Update_One', 'td', 'td'
EXEC sp_changedbowner       'sa'

Do we really need to do any such procedure execution for oracle restore?? Because  I am getting invalid username/password error while restoring dbid.xml (this dbid.xml updated as per the new server information so assume that dbid.xml has accurate information).
