如果Server段没有安装X界面,如何来安装Oracle呢?我们可以使用Oracle提供的静默安装来实现提示符下的Oracle安装。安装前的系统环境变量及内核参数的设置这里就不重复了,可以查看安装光盘中的安装文档。
假设Oracle安装文件已经解压至/u02 。
su - oracle
mkdir -p /u01/app/oracle/
1. 建立静默安装的配置文件
cd /u02/database/response
vi enterprise01.rsp
RESPONSEFILE_VERSION=2.2.1.0.0
FROM_LOCATION="../stage/products.xml"
ORACLE_HOME="/u01/app/oracle/product/10.2.0/db_1/"
ORACLE_HOME_NAME="OraDb10g_home1"
TOPLEVEL_COMPONENT={"oracle.server","10.2.0.1.0"}
DEINSTALL_LIST={"oracle.server","10.2.0.1.0"}
SHOW_SPLASH_SCREEN=false
SHOW_WELCOME_PAGE=false
SHOW_COMPONENT_LOCATIONS_PAGE=false
SHOW_CUSTOM_TREE_PAGE=false
SHOW_SUMMARY_PAGE=false
SHOW_INSTALL_PROGRESS_PAGE=false
SHOW_REQUIRED_CONFIG_TOOL_PAGE=false
SHOW_CONFIG_TOOL_PAGE=false

ACCEPT_LICENSE_AGREEMENT=true
COMPONENT_LANGUAGES={"en"}
CLUSTER_NODES=
INSTALL_TYPE="EE"
s_nameForDBAGrp=dba
s_nameForOPERGrp=dba
b_oneClick=false
SHOW_DATABASE_CONFIGURATION_PAGE=false
b_createStarterDB=false
相关属性的值的意义,请参考Oracle提供的enterprise.rsp文档中的说明 。
2. 开始安装
cd /u02/database/
./runInstaller -silent -responseFile /u02/database/response/enterprise01.rsp
#注意-responseFile参数后的文件路径一定是绝对路径 ,并且enterprise01.rsp oracle用户可读。
执行过程如下:

Please check '/u01/app/oracle/oraInventory/logs/silentInstall2008-05-12_08-26-55PM.log' for more details.

3. 运行安装所需脚本
vi /u01/app/oracle/oraInventory/logs/silentInstall2008-05-12_08-26-55PM.log
查看日志,提示我们用root用户运行如下两个脚本
/u01/app/oracle/oraInventory/orainstRoot.sh
/u01/app/oracle/product/10.2.0/db_1/root.sh
至此Oracle的产品已经安装完成,可是目前为止我们还没有建立数据库。
由于没有X界面无法启动dbca ,所以不能用dbca来帮我们建立数据库。这时候你可能会想到用create database 语句来建立数据库,可是语法实在是繁琐,并且还要运行许多的
oracle脚本 。
下面我们来利用oracle提供的种子数据库还原一个数据库出来。
假设我们要建立的数据库的名称为orcl 。

4.建立我们所需的目录。
mkdir -p /u01/app/oracle/admin/orcl/{a,b,u}dump
mkdir -p /u01/app/oracle/oradata/orcl
找到oracle为种子数据库提供的控制文件并copy至/u01/app/oracle/oradata/orcl 。
cd /u01/app/oracle/product/10.2.0/db_1/assistants/dbca/templates/
cp Seed_Database.ctl /u01/app/oracle/oradata/orcl

5.建立pfile文件
cd /u01/app/oracle/product/10.2.0/db_1/dbs
vi initorcl.ora
*.db_name=SEEDDATA #注:因为Seed_Database.ctl控制文件中记录的db_name为SEEDDATA。
control_files='/u01/app/oracle/oradata/orcl/Seed_Database.ctl'
compatible=10.2.0.1.0

6.启动数据库到mount状态
sqlplus / as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production . Mon May 12 21:48:47 2008
Copyright (c) 1982, 2005, Oracle.  All rights reserved.
Connected to an idle instance.
SQL> startup mount
ORACLE instance started.

使用默认的参数建立spfile
SQL> create spfile from pfile;
重新启动数据库
SQL> shutdown immediate
SQL> startup mount
更改sga_max_size,sga_target参数的值 。
SQL> alter system set sga_max_size=200M scope=spfile;
SQL> alter system set sga_target=160M scope=spfile;
然后再次重新启动数据库
SQL> shutdown immediate
SQL> startup mount


7.用rman连接数据库
rman target /

Copyright (c) 1982, 2005, Oracle.  All rights reserved.
connected to target database: SEEDDATA (DBID=3891038516, not open)
RMAN> list backup;

using target database control file instead of recovery catalog

List of Backup Sets
===================

BS Key  Type LV Size       Device Type Elapsed Time Completion Time
------- ---- -- ---------- ----------- ------------ ---------------
1       Full    89.23M     DISK        00:00:36     30-JUN-05      
        BP Key: 1   Status: AVAILABLE  Compressed: YES  Tag:

  List of Datafiles in backup set 1
  File LV Type Ckp SCN    Ckp Time  Name
  ---- -- ---- ---------- --------- ----
  1       Full 446074     30-JUN-05 /ade/aime_10.2_lnx_push/oracle/oradata/seeddata/system01.dbf
  2       Full 446074     30-JUN-05 /ade/aime_10.2_lnx_push/oracle/oradata/seeddata/undotbs01.dbf
  3       Full 446074     30-JUN-05 /ade/aime_10.2_lnx_push/oracle/oradata/seeddata/sysaux01.dbf
  4       Full 446074     30-JUN-05 /ade/aime_10.2_lnx_push/oracle/oradata/seeddata/users01.dbf

可以看到,我们可以利用/ade/aime_10.2_lnx_push/oracle/oradata/Seed_Database.dfb这个备份集来还原数据库。
但是很明显我们系统中并没有这样一个文件/ade/aime_10.2_lnx_push/oracle/oradata/Seed_Database.dfb ,但是查找发现路径/u01/app/oracle/product/10.2.0/db_1/assistants/dbca/templates下有Seed_Database.dfb文件 。
有两种方法,一个是建立一个软链接/ade/aime_10.2_lnx_push/oracle/oradata/Seed_Database.dfb 指向/u01/app/oracle/product/10.2.0/db_1/assistants/dbca/templates/Seed_Database.dfb 。另一个是创建目录/ade/aime_10.2_lnx_push/oracle/oradata/
并将Seed_Database.dfb copy至其下 。

8.还原数据库
run {
set newname for datafile '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/system01.dbf' to '/u01/app/oracle/oradata/orcl/system01.dbf';
set newname for datafile '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/sysaux01.dbf' to '/u01/app/oracle/oradata/orcl/sysaux01.dbf';
set newname for datafile '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/undotbs01.dbf' to '/u01/app/oracle/oradata/orcl/undotbs01.dbf';
set newname for datafile '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/users01.dbf' to '/u01/app/oracle/oradata/orcl/users01.dbf';
restore database;
switch datafile all;
}

cd /u01/app/oracle/oradata/orcl
[oracle@man /u01/app/oracle/oradata/orcl]$ ls
Seed_Database.ctl  sysaux01.dbf  system01.dbf  undotbs01.dbf  users01.dbf
可以看到我们所需要的数据文件都还原回来了,但是现在还缺少log file 。
我们现在打开数据库。
因为控制文件中记录的log file路径为 /ade/aime_10.2_lnx_push/oracle/oradata/seeddata 所以要先创建相应的目录。
SQL> alter database open resetlogs;
此时,在目录/ade/aime_10.2_lnx_push/oracle/oradata/seeddata 下创建了redo01.log,redo02.log,redo03.log,temp01.dbf文件。
我们要更改这几个文件的路径,所以先将数据库关闭,然后cp /ade/aime_10.2_lnx_push/oracle/oradata/seeddata/× /u01/app/oracle/oradata/orcl/
启动数据库到mount状态,并更改日志和临时文件的路径
SQL> alter database rename file '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/redo01.log' to '/u01/app/oracle/oradata/orcl/redo01.log';

Database altered.

SQL> alter database rename file '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/redo02.log' to '/u01/app/oracle/oradata/orcl/redo02.log';

Database altered.

SQL> alter database rename file '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/redo03.log' to '/u01/app/oracle/oradata/orcl/redo03.log';

Database altered.

SQL> alter database rename file '/ade/aime_10.2_lnx_push/oracle/oradata/seeddata/temp01.dbf' to '/u01/app/oracle/oradata/orcl/temp01.dbf';

Database altered.

SQL> alter database open;

到此数据库已经建立,并且数据文件也放到了我们期待的地方。但是还有一个问题,就是数据库名称不是我们事先期待的。
SQL> show parameter name

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert                 string
db_name                              string      SEEDDATA
db_unique_name                       string      SEEDDATA
global_names                         boolean     FALSE
instance_name                        string      orcl
lock_name_space                      string
log_file_name_convert                string
service_names                        string      SEEDDATA
下面我们将数据库名称SEEDDATA改成我们需要的orcl 。注意此时仅仅更改参数文件的值是不行的,因为控制文件中同样也记录着数据库的名称。

9.更改数据库名称
备份控制文件脚本
SQL> alter database backup controlfile to trace as '/tmp/ctl.txt';
SQL> create pfile from spfile;
将spfile删除,编辑pfile将db_name="SEEDDATA" 改成 db_name="orcl" 。

vi /tmp/ctl.txt 将其中如下一段
CREATE CONTROLFILE REUSE DATABASE "SEEDDATA" NORESETLOGS  NOARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
  GROUP 1 '/u01/app/oracle/oradata/orcl/redo01.log'  SIZE 50M,
  GROUP 2 '/u01/app/oracle/oradata/orcl/redo02.log'  SIZE 50M,
  GROUP 3 '/u01/app/oracle/oradata/orcl/redo03.log'  SIZE 50M
-- STANDBY LOGFILE

DATAFILE
  '/u01/app/oracle/oradata/orcl/system01.dbf',
  '/u01/app/oracle/oradata/orcl/undotbs01.dbf',
  '/u01/app/oracle/oradata/orcl/sysaux01.dbf',
  '/u01/app/oracle/oradata/orcl/users01.dbf',
  '/u01/app/oracle/oradata/orcl/tt.dbf'
CHARACTER SET US7ASCII
;

修改为
CREATE CONTROLFILE REUSE DATABASE "SEEDDATA" set database "ORCL"  RESETLOGS  NOARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
  GROUP 1 '/u01/app/oracle/oradata/orcl/redo01.log'  SIZE 50M,
  GROUP 2 '/u01/app/oracle/oradata/orcl/redo02.log'  SIZE 50M,
  GROUP 3 '/u01/app/oracle/oradata/orcl/redo03.log'  SIZE 50M

DATAFILE
  '/u01/app/oracle/oradata/orcl/system01.dbf',
  '/u01/app/oracle/oradata/orcl/undotbs01.dbf',
  '/u01/app/oracle/oradata/orcl/sysaux01.dbf',
  '/u01/app/oracle/oradata/orcl/users01.dbf',
  '/u01/app/oracle/oradata/orcl/tt.dbf'
CHARACTER SET US7ASCII
;
重新启动数据库到nomount状态 。
运行上面的建立控制文件的脚本,然后打开数据库 。
SQL> alter database open resetlogs;

10.控制文件更名并实现冗余。
修改参数文件initorcl.ora
*.control_files='/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control02.ctl'
,'/u01/app/oracle/oradata/orcl/control03.ctl'

cd /u01/app/oracle/oradata/orcl
mv Seed_Database.ctl control01.ctl
cp control01.ctl control02.ctl
cp control01.ctl control03.ctl
重新启动数据库,大功告成!
