The user SCOTT owns the CUST table that is placed in the SALES tablespace. The user SCOTT
opens a session and executes commands as follows:
SQL> INSERT INTO cust VALUES(101, ‘JACK’);
1 row created.
SQL> INSERT INTO cust VALUES(102, ‘SMITH’);
1 row created.
As a DBA, you execute the following command from another session:
ALTER TABLESPACE sales READ ONLY;
Which statement is true regarding the effect of this command on the transaction in Scott’s
session?
A.
The command fails as a transaction is still pending.
B.
The transaction in Scott’s session is rolled back and the tablespace becomes readonly.
C.
The command waits and the user SCOTT can execute data manipulation language (DML)
statements only as part of the current transaction.
D.
The command hangs until all transactions on the objects in the tablespace commit or rollback,
and then the tablespace is placed in readonly mode.
