oracle 12c创建可插拔数据库（PDB）与用户详解-木庄网络博客

前言

由于oracle 12c使用了CDB-PDB架构，类似于docker，在container-db内可以加载多个pluggable-db，因此安装后需要额外配置才能使用。

一、修改listener.ora , tnsnames.ora

###listener.ora###
LISTENER =
(DESCRIPTION =
 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
 (CONNECT_DATA = (SERVICE_NAME = orcl))
)
#sid list列举cdb和所有pdb的数据库名，所有sid与oracle环境变量保持一致#
SID_LIST_LISTENER =
(SID_LIST =
 (SID_DESC =
 (GLOBAL_DBNAME = orcl) #cdb db_name
 (SID_NAME = orcl)
 )
 (SID_DESC =
 (GLOBAL_DBNAME = pdborcl) #pdb db_name
 (SID_NAME = orcl)
 )
)
###listener.ora###

##tnsnames.ora###
#cdb
orcl =
(DESCRIPTION = 
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) )
 (CONNECT_DATA =
 (SERVICE_NAME = orcl) #cdb的db_name
 )
)
#pdb
pdborcl =
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
 )
 (CONNECT_DATA =
 (SERVICE_NAME = pdborcl) #pdb的db_name
 )
)
##tnsnames.ora###

在客户端连接时使用“service_name+domain_name”连接。如果出现ora-01017，很有可能是

二、创建pdb

cdb相当于操作系统，调用并管理各个pdb。pdb相当于真正提供业务需求的数据库实例。oracle 12c安装后只创建了cdb，需要自己生成相应的pdb。
