篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了oracle 12c怎样创建一个cdb数据库-dbca方式相关的知识，希望对你有一定的参考价值。
一 实验目的
这里想建一个sid为orclcdb的cdb，建两个以orclpdb为前缀的pdb。
假如目前环境没有cdb或者已经有cdb，想新建一个cdb，可通过如下方式创建。
二 实验步骤
2.1 创建dbca建库所需的响应文件
su - oracle
vi dbca_cdb.rsp
添加如下内容：

## Specify values for the variables listed below to customize ##

2.2 dbca建库
dbca -silent -createDatabase -responseFile /home/oracle/dbca_cdb.rsp
2.3 设置cdb数据库开机自启
2.3.1 修改dbstart文件
修改/u01/app/oracle/product/12c/db_1/bin/dbstart文件，确保ORACLE_HOME_LISTNER=的值为$ORACLE_HOME
2.3.2 修改/etc/oratab
将
orclcdb:/u01/app/oracle/product/12c/db_1:N改为orclcdb:/u01/app/oracle/product/12c/db_1:Y
2.3.3 修改/etc/rc.d/rc.local
添加一行：
su oracle -lc /u01/app/oracle/product/12c/db_1/bin/dbstart
--说明：/u01/app/oracle/product/12c/dbhome_1为oracle的安装目录，要根据实际情况进行修改。
reboot试验下看是否能开机自动启动。
2.4 验证
--这里看到了orcl这个实例，是因为在创建cdb之前就有一个orcl实例。
2.5 配置服务名
cd /u01/app/oracle/product/12c/db_1/network/admin
vi tnsnames.ora
新增如下内容
orclpdb1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orclpdb1)
)
)
orclpdb2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orclpdb2)
)
)#测试服务是否通
2.6 连接pdb
[oracle@PC admin]$ sqlplus sys@orclpdb1 as sysdba
