oracle多个实例创建

1. 修改ORACLE用户环境变量

vi /home/oracle/.bash_profile ,修改export LANG=EN_US   同时生效。 source .bash_profile

2. 创建数据库文件夹

/oradata为数据库表空间的存放路径

/oradata/system 为系统表空间和在线日志的存放路径

/oradata/tbs01为表空间数据文件的存放路径。

将/oradata下的用户所有者更改为oracle用户:

chown -R oracle:dba /oradata/

赋予该文件夹可操作权限:chmod 755 /oradata

3. 数据库创建

dbca -silent -responseFile /home/oracle/tcms/dbca.rsp

dbca.rsp脚本的内容如下:

[GENERAL]

RESPONSEFILE VERSION = "10.2.0"

OPERATION_TYPE="createDatabase"

[CREATEDATABASE]

TEMPLATENAME = "General_Purpose.dbc"

GDBNAME = "TCMS"//数据库名称

SID="TCMS"//数据库实例名

EMCONFIGURATION = "NONE"

SYSPASSWORD = "password"

STORAGETYPE=FS

DATAFILEDESTIINATION = /oradata/system  //为系统表空间和在线日志的存放路径

AUTOMATICMEMORYMANAGEMENT = "TRUE"

CHARACTERSET = "ZHS16GBK"

TOTALMEMORY = "10336"

4.创建表空间及数据库基本表

sqlplus '/as sysdba'

@create_tablespace.sql

@create_ora_user.sql

exit;

其中create_tablespace.sql内容：

create tablespace business_data_ts01 datafile

'/oradata/tbs01/business_data_ts01.dbf' size 5120m autoextend off;

create tablespace business_ind_ts01 datafile

'/oradata/tbs01/business_ind_ts0101.dbf' size 1024m autoextend off;

其中create_ora_user.sql内容:

create user business identified by business default tablespace business_data_ts01

quota unlimited on business_data_ts01

quota unlimited on business_ind_ts01

account unlock;

grant connect ,resource to business;

grant dba to business;

5.登录business用户 sqlplus business/business

进行表创建:@ora_create_tables.sql

6.启动监听：

lsnrctl start
