====== [DOC] Working with pluggable databases ======

====== Mangement ======
===== Create a pluggable database =====
<code sql>CREATE PLUGGABLE DATABASE PDB01 ;
</code>

===== Startup pluggable database =====
<code sql>
ALTER PLUGGABLE DATABASE PDB01 OPEN ;
</code>

===== tnsnames.ora =====
Tnsnames is necessary for connecting to the pluggable databases with cli tools (sql*, expdp...)
<code bash>
vim  $ORACLE_HOME/network/admin/tnsnames.ora
</code>
<code>
PDB01 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PDB01)
    )
  )
</code>

====== Working with PDB's ======
===== List of Services (pdbs+cdbs) =====
<code sql>SELECT NAME, CON_ID FROM V$ACTIVE_SERVICES ;
</code>

===== Info about currently connected instance =====
<code sql>
SET LINESIZE 200
SET PAGESIZE 10000
SET SERVEROUTPUT ON
COLUMN "DB DETAILS" FORMAT A100\
SELECT
 'DB_NAME: ' ||sys_context('userenv', 'db_name')||
 ' / CDB?: ' ||(select cdb from v$database)||
 ' / AUTH_ID: ' ||sys_context('userenv', 'authenticated_identity')||
 ' / USER: ' ||sys_context('userenv', 'current_user')||
 ' / CONTAINER: '||nvl(sys_Context('userenv', 'con_Name'), 'NON-CDB')
 "DB DETAILS"
 FROM DUAL
 /
</code>

===== List PDBS from current container =====
<code sql>
COLUMN "RESTRICTED" FORMAT A10
select 
   v.name, 
   v.open_mode, 
   nvl(v.restricted, 'n/a') "RESTRICTED", 
   d.status
from 
   v$pdbs     v 
inner join 
   dba_pdbs d
using (GUID)
order by v.create_scn;
</code>

===== Connect from CDB =====
<code sql>
ALTER SESSION SET CONTAINER=PDB01 ;
</code>

===== With sql* =====
<code bash>
sqlplus 'sys/DBA@PDBTEST1 AS SYSDBA'
</code>
