Oracle 12C -- 手动创建CDB

1.指定oracle_sid

$ export ORACLE_SID=db12

2.指定环境变量

　　比如ORACLE_BASE、ORACLE_HOME、PATH(要包含$ORACLE_HOME/bin)
3.选定验证方式

　　·操作系统验证

　　·口令文件验证
4.创建初始化参数文件

$ vi initdb12.ora
db_name='db12'
memory_target=2G
processes = 150
db_block_size=8192
db_domain=''
diagnostic_dest='/u12/app/oracle'
dispatchers='(PROTOCOL=TCP) (SERVICE=db12XDB)'
open_cursors=300 
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='undotbs1'
control_files ='/u12/app/oracle/oradata/db12/control01.ctl','/u12/app/oracle/oradata/db12/control02.ctl'
compatible ='12.0.0'
audit_file_dest='/u12/app/oracle/admin/db12/adump'
audit_trail='db' 
enable_pluggable_database=true

5.如果是windows，需要创建一个实例

> oradim -NEW -SID <sid> -STARTMODE MANUAL -PFILE <file>

6.连接到实例

$ sqlplus /nolog
SQL> conn /as sysdba
Connected to an idle instance.

7.创建spfile

SQL> create spfile from pfile;

File created.

SQL> 

8.启动实例

SQL> startup nomount;
ORACLE instance started.

9.执行create database命令

create database db12
  user sys identified by oracle
  user system identified by oracle
  logfile group 1 ('/u12/app/oracle/oradata/db12/redo01a.log','/u12/app/oracle/oradata/db12/redo01b.log') size 100m,
          group 2 ('/u12/app/oracle/oradata/db12/redo02a.log','/u12/app/oracle/oradata/db12/redo02b.log') size 100m, 
          group 3 ('/u12/app/oracle/oradata/db12/redo03a.log','/u12/app/oracle/oradata/db12/redo03b.log') size 100m
  maxloghistory 1
  maxlogfiles 16
  maxlogmembers 3
  maxdatafiles 1024
  character set al32utf8
  national character set al16utf16
  extent management local
  datafile '/u12/app/oracle/oradata/db12/system01.dbf' size 700m reuse autoextend on next 10240k maxsize unlimited
  sysaux datafile '/u12/app/oracle/oradata/db12/sysaux01.dbf' size 550m reuse autoextend on next 10240k maxsize unlimited
  default tablespace users
    datafile '/u12/app/oracle/oradata/db12/users01.dbf' size 500m reuse autoextend on maxsize unlimited
  default temporary tablespace tempts1
    tempfile '/u12/app/oracle/oradata/db12/temp01.dbf' size 20m reuse autoextend on next 640k maxsize unlimited
  undo tablespace undotbs1
    datafile '/u12/app/oracle/oradata/db12/undotbs01.dbf' size 200m reuse autoextend on next 5120k maxsize unlimited
  enable pluggable database
    seed
    file_name_convert = ('/u12/app/oracle/oradata/db12',
                         '/u12/app/oracle/oradata/db12/pdb1')
    system datafiles size 125m autoextend on next 10m maxsize unlimited
    sysaux datafiles size 100m
    user_data tablespace usertbs
    datafile '/u12/app/oracle/oradata/db12/pdb1/usertbs01.dbf' size 200m reuse autoextend on maxsize unlimited;

10.运行脚本创建数据字典视图

@?/rdbms/admin/catcdb.sql

11.windows的话设置开机自动启动

> ORADIM -EDIT -SID <sid> -STARTMODE AUTO -SRVCSTART SYSTEM [-SPFILE]

 12.查看

SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;

    CON_ID       DBID NAME                           OPEN_MODE
---------- ---------- ------------------------------ ----------
         2 3463549582 PDB$SEED                       READ ONLY

SQL> select con_id,dbid,name,open_mode from v$containers;

    CON_ID       DBID NAME                           OPEN_MODE
---------- ---------- ------------------------------ ----------
         1 1741224387 CDB$ROOT                       READ WRITE
         2 3463549582 PDB$SEED                       READ ONLY
