Oracle 用脚本安装第二个数据库

  • 安装第二个数据库:
登录oracle用户进入家目录,添加配置环境变量:
vi .bash_profier
ORACLE_SID=prod2

  

 
  • 临时环境变量:
$export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
$export ORACLE_SID=prod2

  

 
  • 创建第二个数据库文件目录:
$mkdir -p /u01/app/oracle/oradata/prod2

  

 
  • 创建sys用户密码文件:
$cd  /u01/app/oracle/product/11.2.0/db_1/dbs
$orapwd file=orapwprod2 password=oracle
 

  

  • 创建一个可读参数文件:
$vi initprod2.ora
添加:
DB_NAME=prod2
sga_target=500M
control_files=‘/u01/app/oracle/oradata/prod2/control01.ctl‘

  

 
  • 打开实例进入nomount模式,创建数据库系统proc,view ……:
SQL> sqlplus / as sysdba
SQL> startup nomount;
SQL> create spfile from pfile;
SQL> shutdown immediate;
SQL> startup nomount;
SQL> alter system set db_create_file_dest=‘/u01/app/oracle/oradata/prod2‘;
SQL> create database character set AL32UTF8 extent management local;
SQL> @?/rdbms/admin/catalog.sql;
SQL> @?/rdbms/admin/catproc.sql;
SQL> alter user system identified by oracle account unlock;
SQL> conn system/oracle
SQL> @?/sqlplus/admin/pupbld.sql;

  

 
  • 验证实例:
 
SQL> show parameter name;
 
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert                 string
db_name                              string      prod2
db_unique_name                       string      prod2
global_names                         boolean     FALSE
instance_name                        string      prod2
lock_name_space                      string
log_file_name_convert                string
service_names                        string      prod2
 

  

 
  • 多个数据库切换:. oraenv
[oracle@test ~]$ . oraenv
ORACLE_SID = [prod2] ? prod1
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 is /u01/app/oracle

  

 
  • 当再切入第二的环境变量的时候的,会无法自动识别oracle家目录,需手动输入地址,解决方法如下:
vi /etc/oratab(当用dbca窗口删库时,添加oratab文件后,dbca数据库列表会显示数据库名) 添加到最后一行参数:(Y代表支持dbstart和dbshut启停数据库) prod2:/u01/app/oracle/product/11.2.0/db_1:Y    
# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
 
 
# A colon, ‘:‘, is used as the field terminator.  A new line terminates
# the entry.  Lines beginning with a pound sign, ‘#‘, are comments.
#
# Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively.  The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
prod1:/u01/app/oracle/product/11.2.0/db_1:Y
prod2:/u01/app/oracle/product/11.2.0/db_1:Y

  

  • 演示1:
[oracle@test ~]$ ps -ef|grep smon
oracle   11062     1  0 00:25 ?        00:00:00 ora_smon_prod2
oracle   12799 12285  0 02:12 pts/2    00:00:00 grep smon
[oracle@test ~]$ dbshut
ORACLE_HOME_LISTNER is not SET, unable to auto-stop Oracle Net Listener

Processing Database instance "prod1": log file /u01/app/oracle/product/11.2.0/db_1/shutdown.log
Processing Database instance "prod2": log file /u01/app/oracle/product/11.2.0/db_1/shutdown.log
[oracle@test ~]$ ps -ef|grep smon
\oracle   12955 12285  0 02:12 pts/2    00:00:00 grep smon

  

 
  • 演示2:
[oracle@test ~]$ . oraenv
ORACLE_SID = [prod2] ? prod1
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 is /u01/app/oracle
[oracle@test ~]$ dbstart
ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
Usage: /u01/app/oracle/product/11.2.0/db_1/bin/dbstart ORACLE_HOME
Processing Database instance "prod1": log file /u01/app/oracle/product/11.2.0/db_1/startup.log
Processing Database instance "prod2": log file /u01/app/oracle/product/11.2.0/db_1/startup.log
[oracle@test ~]$ ps -ef|grep smon
oracle   13130     1  0 02:13 ?        00:00:00 ora_smon_prod1
oracle   13239     1  0 02:13 ?        00:00:00 ora_smon_prod2
oracle   13390 12285  0 02:14 pts/2    00:00:00 grep smon

[oracle@test ~]$ ps -ef|grep smon
oracle   13550 12285  0 02:14 pts/2    00:00:00 grep smon
 

  

 
  • 监听器没有受到快捷启停命令的影响:
[oracle@test ~]$ ps -ef|grep lsnr
oracle   13609     1  0 02:18 ?        00:00:00 /u01/app/oracle/product/11.2.0/db_1/bin/tnslsnr LISTENER -inherit
oracle   13621 12285  0 02:19 pts/2    00:00:00 grep lsnr
