oracle手动创建数据库_oracle怎么建库

ORACLE 手动建库

ORACLE10GR2手动建库大致分为以下几个步骤

编辑.bash_profile文件，设置环境变量

创建所需目录结构

创建初始化参数文件

执行建库脚本

下面以创建test数据库为例

1、编辑.bash_profile文件，添加ORACLE_SID环境变量

在.bash_profile文件中指定ORACLE_SID

export ORACLE_SID=test[oracle@target scripts]$ source /home/oracle/.bash_profile

[oracle@target scripts]$ echo $ORACLE_SID

test

2、创建所需目录结构mkdir -p /home/oracle/admin/test/adump

mkdir -p /home/oracle/admin/test/bdump

mkdir -p /home/oracle/admin/test/cdump

mkdir -p /home/oracle/admin/test/dpdump

mkdir -p /home/oracle/admin/test/pfile

mkdir -p /home/oracle/admin/test/udump

mkdir -p /home/oracle/oradata/test

3、创建初始化参数文件–1、生成初始化参数文件

[oracle@target pfile]$ cd /home/oracle/admin/test/pfile

[oracle@target pfile]$ vi init.ora

db_block_size=8192

db_file_multiblock_read_count=8

open_cursors=300

db_domain=””

db_name=test

background_dump_dest=/home/oracle/admin/test/bdump

core_dump_dest=/home/oracle/admin/test/cdump

user_dump_dest=/home/oracle/admin/test/udump

control_files=(“/home/oracle/oradata/test/control01.ctl”, “/home/oracle/oradata/test/control02.ctl”, “/home/oracle/oradata/test/control03.ctl”)

job_queue_processes=100

compatible=10.2.0.3.0

processes=500

sga_target=274726912

audit_file_dest=/home/oracle/admin/test/adump

remote_login_passwordfile=EXCLUSIVE

dispatchers=”(PROTOCOL=TCP) (SERVICE=testXDB)”

pga_aggregate_target=91226112

undo_management=AUTO

undo_tablespace=UNDOTBS1

–2、连接ORACLE_SID=test实例，并以spfile启动数据库到nomount状态

[oracle@target pfile]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.4.0 – Production on 星期六 12月 14 23:35:09 2013

Connected to an idle instance.

SQL> create spfile=’$ORACLE_HOME/dbs/spfiletest.ora’ from pfile=’$ORACLE_BASE/admin/test/pfile/init.ora’;

File created.

SQL> startup nomount

ORACLE instance started.

Database Buffers 167772160 bytes

Redo Buffers 6303744 bytes

4、执行建库脚本–1、执行create database脚本

SQL> create database test

user sys identified by oracle

user system identified by oracle

logfile group 1 (‘/home/oracle/oradata/test/redo01.log’) size 50m,

group 2 (‘/home/oracle/oradata/test/redo02.log’) size 50m,

group 3 (‘/home/oracle/oradata/test/redo03.log’) size 50m

maxlogfiles 16

maxlogmembers 3

maxloghistory 1

maxdatafiles 100

maxinstances 8

datafile ‘/home/oracle/oradata/test/system01.dbf’ size 100m

autoextend on next 10m maxsize unlimited

autoextend on next 10m maxsize unlimited

default tablespace users

datafile ‘/home/oracle/oradata/test/users01.dbf’ size 100m

autoextend on next 20m segment space management auto

default temporary tablespace temp

tempfile ‘/home/oracle/oradata/test/temp01.dbf’ size 100m

autoextend on next 20m maxsize unlimited

undo tablespace undotbs1

datafile ‘/home/oracle/oradata/test/undotbs101.dbf’ size 100m

autoextend on next 20m maxsize unlimited;

–2、生成数据字典

SQL> @$ORACLE_HOME/rdbms/admin/catalog.sql

SQL> @$ORACLE_HOME/rdbms/admin/catproc.sql

–以system用户，运行pupbld.sql脚本

SQL> conn system/oracle

Connected.

SQL> @$ORACLE_HOME/sqlplus/admin/pupbld.sql

最后全备份数据库。
