User not able to view table entries oracle 12c

Question

I am a newbie to the database and trying to learn roles and privilege in oracle12c. I am logged in as user dba643 and have following codes.

create table test
(
  obj1 Number,
  obj2 Varchar2(3)
);


Insert into test values('1','A');
Insert into test values('2','B');

create user rtest identified by rtest;

grant connect,resource to rtest;

grant select,insert,update,delete on test to rtest;

After logging in as rtest user and issuing the following select statement:

select * from dba643.test;

The user rtest is able to see the two table entries. However, if the user dba643 inserts a new record into the test table, that newly inserted record cannot be viewed by the user rtest . Similarly, the user rtest is able to insert a record into test table, however, the inserted record cannot be viewed by the dba643 user. Is there something basic I am missing in this?

Answer 1

Use "commit".

I am not seeing any commit on your code. Without using commit you can see the entries only on dba643 user. After committing records will be available for all user.
