There is absolutely no need to grant DBA to that other user. This is very insecure.

As a DBA you should execute the following SQL commands:

Revoke DBA from That_User;
Create Role MyAccount_Read;
Grant Connect to MyAccount_Read;
Create Role MyAccount_Update;
Grant MyAccount_Read to MyAccount_Update;
Grant Select on MyAccount.Table1 to MyAccount_Read;
Grant Select on MyAccount.Table2 to MyAccount_Read;
Grant Insert, Update, Delete on MyAccount.Table1 To MyAccount_Update;
Grant Insert, Update, Delete on MyAccount.Table2 To MyAccount_Update;
Grant MyAccount_Read to User_That_Needs_ReadOnly_Privs;
Grant MyAccount_Update to User_That_Needs_Update_Privs;
Create Public Synonym Table1 for MyAccount.Table1;
Create Public Synonym Table2 for MyAccount.Table2;
