Now connect your pluggable database

SQL> alter session set container=TEST;

Session altered.

Create one tablespace in pluggable database .

SQL> CREATE TABLESPACE TEST;

Tablespace created.

Create one user and grant quota on this tablespace to that user.

SQL> create user test identified by oracle default tablespace test quota unlimited on test;

User created.
SQL> grant create session to test;

Grant succeeded.

Now lets create a table which will be stored to TEST tablespace.

SQL> create table test.tst(no number,name varchar2(100), city varchar2(50)) tablespace test;

Table created.

SQL> insert into test.tst values(1,'jagruti','palanpur');

1 row created.

SQL> COMMIT;

Commit complete.

SQL> insert into test.tst select * from test.tst;

1 row created.

SQL> COMMIT;

Commit complete.

SQL> insert into test.tst select * from test.tst;

2 rows created.

SQL> /

4 rows created.

SQL> /

8 rows created.

SQL> COMMIT;

Commit complete.

SQL> 

Now lets check data of this table by connecting to TEST user

SQL> conn test/oracle@test
Connected.
SQL> select count(*) from tst;

  COUNT(*)

Lets again check list failure to crosscheck if any failure still exist


RMAN> list failure;

Database Role: PRIMARY

no failures found that match specification

RMAN>

Let us open TEST pdb now.

SQL> ALTER PLUGGABLE DATABASE TEST OPEN;

Pluggable database altered.

We can see here after RMAN’s repair failure the pdb is open now.
