上一篇已经用应答文件安装了数据库软件，这一篇博客接着安装12c新推出的CDB和PDB。

一，配置netca

1. 复制并修改netca配置文件

[oracle@snow response]$ cp -rp netca.rsp cdb_pdb_netca.rsp

[oracle@snow response]$ vi cdb_pdb_netca.rsp

[GENERAL]

RESPONSEFILE_VERSION="12.1"

CREATE_TYPE="CUSTOM"

[oracle.net.ca]

INSTALLED_COMPONENTS={"server","net8","javavm"}

INSTALL_TYPE=""custom""

LISTENER_NUMBER=1

LISTENER_NAMES={"LISTENER"}

LISTENER_PROTOCOLS={"TCP;1521"}

LISTENER_START=""LISTENER""

NAMING_METHODS={"TNSNAMES","ONAMES","HOSTNAME"}

NSN_NUMBER=1

NSN_NAMES={"EXTPROC_CONNECTION_DATA"}

NSN_SERVICE={"PLSExtProc"}

NSN_PROTOCOLS={"TCP;HOSTNAME;1521"}

2. 确认ORACLE_HOME环境变量已经设定，以便于直接输入netca -silent ...

oracle@snow response]$echo $ORACLE_HOME

/u01/app/oracle/product/12.1.0.1/db_1

3. 采用应答文件配置netca

[oracle@snow response]$netca -silent -responseFile /home/oracle/orainst/12.1.0.1/database/response/cdb_pdb_netca.rsp

Parsing command line arguments:

Parameter "silent" = true

Parameter "responsefile" = /home/oracle/orainst/12.1.0.1/database/response/cdb_pdb_netca.rsp

Done parsing command line arguments.

Oracle Net Services Configuration:

Configuring Listener:LISTENER

Listener configuration complete.

Oracle Net Listener Startup:

Running Listener Control:

/u01/app/oracle/product/12.1.0.1/db_1/bin/lsnrctl start LISTENER

Listener Control complete.

Listener started successfully.

Profile configuration complete.

Oracle Net Services configuration successful. The exit code is 0

4. netca配置完毕，测试一下效果

[oracle@snow response]$lsnrctl status

(DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521)))

The listener supports no services

The command completed successfully

二，创建cdb+pdb

1. 创建cdb+pdb的应答文件如下：

[oracle@snow response]$ cat cdb_pdb.rsp

[GENERAL]

RESPONSEFILE_VERSION = "12.1.0"

OPERATION_TYPE = "createDatabase"

[CREATEDATABASE]

GDBNAME = "cdb"

SID = "cdb"

CREATEASCONTAINERDATABASE =true

NUMBEROFPDBS =1

PDBNAME =pdb1

TEMPLATENAME = "General_Purpose.dbc"

STORAGETYPE=FS

CHARACTERSET = "AL32UTF8"

NATIONALCHARACTERSET= "UTF8"

SAMPLESCHEMA=TRUE

[CONFIGUREDATABASE]

SYSDBAUSERNAME = "sys"

SYSMANPASSWORD = "oracle"

DBSNMPPASSWORD = "oracle"

[ADDINSTANCE]

DB_UNIQUE_NAME = "cdb"

NODELIST=

SYSDBAUSERNAME = "sys"

[CREATEPLUGGABLEDATABASE]

SOURCEDB = "cdb"

PDBNAME = "pdb1"

2. 使用应答文件创建数据库

这里有些不足的地方是密码没有配置到reponse文件中，在执行过程中需要手工输入密码。

[oracle@snow response]$dbca -silent -createDatabase -responseFile /home/oracle/orainst/12.1.0.1/database/response/cdb_pdb.rsp

Enter SYS user password:oracle

Enter SYSTEM user password:oracle

Enter PDBADMIN User Password:oracle

从进度中看出任务并没有完成，没有任何关于pdb的输出，查看/u01/app/oracle/cfgtoollogs/dbca/cdb/cdb8.log发现一个经典错误

[oracle@snow response]$ more /u01/app/oracle/cfgtoollogs/dbca/cdb/cdb8.log

这个错误在图形安装cdb时也出现过，是因为perl的问题，采用替换的方式搞定！

[oracle@snow bin]$ mv perl perl.bak

[oracle@snow bin]$ln -s /usr/bin/perl .

lrwxrwxrwx 1 oracle oinstall 13 Mar 2 10:28 perl -> /usr/bin/perl

3. 重新执行使用应答文件创建数据库

[oracle@snow response]$dbca -silent -createDatabase -responseFile /home/oracle/orainst/12.1.0.1/database/response/cdb_pdb.rsp

Enter SYS user password:

Enter SYSTEM user password:

Enter PDBADMIN User Password:

4. 测试一下创建效果

[oracle@snow response]$ sqlplus / as sysdba

到这里使用应答文件安装数据库软件、配置netca、创建CDB数据库和PDB数据库已经演示完毕。

跟oracle10g相比，12c的response方式复杂了些，而且随着CDB和PDB的出现，配置安装更加复杂。想要完全掌握12c的应答方式安装数据库需要用些时间多做实验。因为应答方法不仅可以创建单实例的12c数据库，也可以创建RAC数据库。一看到RAC，难度和复杂度就成倍增加了。

生产环境中使用图形方式DBCA，使用静默方式调用DBCA还是使用CREATE DATABASE方式创建数据库还是应答方式创建数据库没有最好的方法、只有更合适的方法。如果需要快速的部署云平台oracle数据库，应答方式无疑是最佳选择，简单快速。只需要交互式配置些参数就可以实现一键安装。
