Grant privilege on all objects in a Schema to a user in Oracle Database

In this example I have given select on all tables in schema test1 to user test2. As well grant all DML privilege on tables and views, and grant execute on procedures, functions and packages in a schema test1 to user test2.

Table created.
SQL> show user;
