Oracle 12c 如何連接到 CDB 和 PDB

1  連接到CDB

和普通實(shí)例1樣的連接。 指定ORACLE_SID 以后可使用OS認(rèn)證，也能夠使用密碼進(jìn)行連接。

[oracle@Ora12c /]$ echo $ORACLE_SID

cndba

[oracle@Ora12c /]$ sqlplus / as sysdba

SQL> conn system/oracle         

Connected.

SQL>

--查看CDB中可用的service：

SQL> COLUMN name FORMAT A30

SQL> SELECT name,pdb

  2 FROM   v$services

  3  ORDER BY name;

NAME                           PDB

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

SYS$BACKGROUND                 CDB$ROOT

SYS$USERS                      CDB$ROOT

cndba                          CDB$ROOT

cndbaXDB                       CDB$ROOT

pcndba2                        PCNDBA2

pdbcndba                       PDBCNDBA

6 rows selected.

--通過lsnrctl 也能夠判斷：

[oracle@Ora12c /]$ lsnrctl service

[oracle@Ora12c /]$

通過這些service，就能夠遠(yuǎn)程連接CDB。

--通過TNSNAMES.ORA連接：

在tnsnames.ora 中配置以下：

cndba =

 (DESCRIPTION =

   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))

   (CONNECT_DATA =

2  在不同Container database中切換

在12c的架構(gòu)中，由于有CDB和 PDB的存在，所以會有很多不同的container，所以在連接到不同的container時，就需要進(jìn)行切換。

--查看當(dāng)前的container：

SQL> show con_name

CON_NAME

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

CDB$ROOT

SQL> SELECT SYS_CONTEXT('USERENV','CON_NAME') FROM   dual;

SYS_CONTEXT('USERENV','CON_NAME')

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

CDB$ROOT

SQL> set lin 140

SQL> select con_id, dbid,guid, name , open_mode from v$pdbs;

   CON_ID       DBID GUID                             NAME       OPEN_MODE

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

        2 4088301206 F7C1E3C96BBF0585E0430A01A8C05459 PDB$SEED   READ ONLY

        3  426143573F7C209EB1DFC0854E0430A01A8C0B787 PDBCNDBA   READ WRITE

        4 1231796139 F812DE1B6A8F363AE0430A01A8C0C759 PCNDBA2    READ WRITE

--切換container：

SQL> alter session setcontainer=pcndba2;

Session altered.

SQL> show con_name

CON_NAME

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

PCNDBA2

3  連接到PDB
