Create local user in oracle pluggable database

In this short article, I will give a brief idea about how to create a local user in a pluggable database and how to check its status as well.

Basically, with this multitenant architecture concept, there are two types of users common user and local user, common users are shared across multiple pluggable databases while local user is specific to a particular database, here we will discuss how to create a local user

SQL> alter session set container=technopdb; 

Session altered.

 

SQL> create user techno_user identified by test123;

 

User created.

 

SQL> grant create session to techno_user;

 

Grant succeeded.

 

SQL> show pdbs

 

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

         3 TECHNOPDB                      READ WRITE NO

SQL>

SQL> select username, con_id from cdb_users where username='TECHNO_USER';

 

USERNAME                      CON_ID

------------------------- ----------

TECHNO_USER                        3

 

SQL> select d.username, c.con_id,p.name from dba_users d, cdb_users c , v$pdbs p where d.username='TECHNO_USER' and d.username=c.username and p.con_id=c.con_id;

 

USERNAME                      CON_ID NAME

------------------------- ---------- --------------------------------------------------------------------------------------------------------------------------------

TECHNO_USER                        3 TECHNOPDB

Here we can check, how to connect to pluggable database using  local user

if you are trying it from your local machine/desktop then below command will work fine, you just need to have ip address and port number and if you are using tnsnames then mention the in the connection string
