用SQL命令手工创建CDB

1.设置环境变量
  $ export ORACLE_SID=ora12c
  $ export ORACLE_HOME=/home/oracle/product/12.1.0/db1
  $ export PATH=$ORACLE_HOME/bin:$PATH

2.创建文本参数文件
  $ vi initora12c.ora
    db_name='ora12c'
    enable_pluggable_database=true
    audit_trail='db'
    control_files='/home/oracle/oradata/ora12c/control01.ctl','/home/oracle/oradata/ora12c/control02.ctl'
    db_block_size=8192
    db_domain=''
    memory_target=796917760
    memory_max_target=796917760
    open_cursors=300
    processes=300
    remote_login_passwordfile='EXCLUSIVE'
    undo_tablespace='UNDOTBS1'

3.创建数据库脚本
  $ vi crtcdb.sql
    CREATE DATABASE CDB
    MAXLOGFILES 16
    MAXLOGMEMBERS 4
    MAXDATAFILES 1024
    MAXINSTANCES 1
    MAXLOGHISTORY 1024
    CHARACTER SET ZHS16GBK
    NATIONAL CHARACTER SET AL16UTF16
    DATAFILE
    '/home/oracle/oradata/ora12c/system01.dbf' SIZE 500M
    EXTENT MANAGEMENT LOCAL
    UNDO TABLESPACE undotbs1 DATAFILE
    '/home/oracle/oradata/ora12c/undotbs01.dbf' SIZE 800M
    SYSAUX DATAFILE
    '/home/oracle/oradata/ora12c/sysaux01.dbf' SIZE 500M
    DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE
    '/home/oracle/oradata/ora12c/temp01.dbf' SIZE 500M
    DEFAULT TABLESPACE USERS DATAFILE
    '/home/oracle/oradata/ora12c/users01.dbf' SIZE 50M
    LOGFILE GROUP 1
    ('/home/oracle/oradata/ora12c/redo01a.rdo') SIZE 50M,
    GROUP 2
    ('/home/oracle/oradata/ora12c/redo02a.rdo') SIZE 50M
    USER sys IDENTIFIED BY test
    USER system IDENTIFIED BY test
    USER_DATA TABLESPACE userdt DATAFILE
    '/home/oracle/oradata/ora12c/userdt01.dbf' SIZE 500M
    ENABLE PLUGGABLE DATABASE
    SEED FILE_NAME_CONVERT = ('/home/oracle/oradata/ora12c','/home/oracle/oradata/ora12c/pdbseed');

4.创建相应目录
  $ mkdir -p /home/oracle/oradata/ora12c/pdbseed
  
5.创建数据库
  $ sqlplus / as sysdba
  SQL> @crtcdb.sql

6.运行内置脚本
  $ sqlplus / as sysdba
  SQL> @$ORACLE_HOME/rdbms/admin/catalog.sql
            @$ORACLE_HOME/rdbms/admin/catproc.sql
  SQL> conn system/test
            @$ORACLE_HOME/sqlplus/admin/pupbld.sql
