Oracle 12C -- 手动创建CDB

时间:2024-12-09 10:33:38

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 =
db_block_size=
db_domain=''
diagnostic_dest='/u12/app/oracle'
dispatchers='(PROTOCOL=TCP) (SERVICE=db12XDB)'
open_cursors=
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. Total System Global Area bytes
Fixed Size bytes
Variable Size bytes
Database Buffers bytes
Redo Buffers bytes
SQL>

9.执行create database命令

create database db12
user sys identified by oracle
user system identified by oracle
logfile group ('/u12/app/oracle/oradata/db12/redo01a.log','/u12/app/oracle/oradata/db12/redo01b.log') size 100m,
group ('/u12/app/oracle/oradata/db12/redo02a.log','/u12/app/oracle/oradata/db12/redo02b.log') size 100m,
group ('/u12/app/oracle/oradata/db12/redo03a.log','/u12/app/oracle/oradata/db12/redo03b.log') size 100m
maxloghistory
maxlogfiles
maxlogmembers
maxdatafiles
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
---------- ---------- ------------------------------ ----------
PDB$SEED READ ONLY SQL> select con_id,dbid,name,open_mode from v$containers; CON_ID DBID NAME OPEN_MODE
---------- ---------- ------------------------------ ----------
CDB$ROOT READ WRITE
PDB$SEED READ ONLY SQL>
