如何配置Hibernate连接oracle12c 的PDB和CDB数据库

1 连接到CDB

和普通实例一样的连接。 指定ORACLE_SID 以后可以使用OS认证，也可以使用密码进行连接。

[oracle@Ora12c /]$ echo $ORACLE_SID
cndba
[oracle@Ora12c /]$ sqlplus / as sysdba

SQL> conn system/oracle

--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.

--通过lsnrctl 也可以判断：
[oracle@Ora12c /]$ lsnrctl service

通过这些service，就可以远程连接CDB。

--通过TNSNAMES.ORA连接：

在tnsnames.ora 中配置如下：
cndba =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cndba)
)
)

2 在不同Container database中切换

在12c的架构中，因为有CDB和 PDB的存在，所以会有很多不同的container，所以在连接到不同的container时，就需要进行切换。

--查看当前的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

--切换container：
SQL> alter session setcontainer=pcndba2;
Session altered.

SQL> show con_name

CON_NAME
------------------------------
PCNDBA2

3 连接到PDB

--EZCONNECT:

C:\Users\Dave>sqlplussystem/oracle@192.168.1.10:1521/pcndba2

SQL>

--TNSNAMES.ora

在tnsnames.ora 中添加如下内容：
pcndba =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pcndba2)
)
)
