Oracle12c: How to create PDB in manually

Posted 2023-02-15 yexianyi

Pre-condition: Go through my last blog.

Install:

1. Mount and open CDB

   sqlplus / as sysdba;
   
   startup nomount ;
   
   alter database open ;
   
   conn sys@NDLNE as sysdba ;

2. Create PDB

   create pluggable database pdb1
   admin user pdb1_admin identified by pdb1_admin
   /

3. Open PDB

   alter pluggable database pdb1 open ;

4. Create common user
   1. Make sure current user is "SYS" and current container is "CDB$ROOT"

      SQL> show user
      USER is "SYS"
      SQL> show con_name
      
      CON_NAME
      ------------------------------
      CDB$ROOT
      

   2. Create common user

      create user c##cdbuser identified by common 
      container = all ;

   3. Grant privilege

      grant connect to c##cdbuser ;
      grant create session to c##cdbuser ;

   4. Test

      SQL> connect c##cdbuser/common@NDLNE ;
      Warning:  Product user profile information not loaded!
      You may need to run PUPBLD.SQL as SYSTEM
      Connected.
      
      SQL> show user
      USER is "C##CDBUSER"
      

5. Create Net Service Name in tnsnames.ora

   # tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.2.0/dbhome_1/network/admin/tnsnames.ora
   # Generated by Oracle configuration tools.
   
   PDB1 =
     (DESCRIPTION =
       (ADDRESS_LIST =
         (ADDRESS = (PROTOCOL = TCP)(HOST = centos8.linuxvmimages.local)(PORT = 1521))
       )
       (CONNECT_DATA =
         (SERVICE_NAME = PDB1)
       )
     )
   

6. Test Net Service by tnsping

   [oracle@centos8 ~]$ tnsping PDB1
