HP-UX静默安装oracle11g过程

HP-UX 安装oracle11g过程

规划：

安装文件存放在/tmp目录下，目录层次自拟

数据库安装在/orain目录下，目录层次自拟

数据库数据文件存放在/oracle目录下，目录层次自拟

 

#代表在root用户下操作

$代表在oralce用户下操作

1、下载安装包

机器是HP-UX Itanium的，找对应的文件进行下载，下载链接为：http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html，我下载的版本是：Oracle Database 11g Release 1 (11.1.0.6.0) for HP-UX Itanium 。

这里做个说明，down下来后进行解压，找到数据库的doc，看快速安装指导，那个里面会讲安装所需的硬件及相关环境。现在服务器自然是硬盘大，内存大，这些硬件条件大概看下就可以，但是版本却是一个很重要的问题，因为我刚开始下载的是：Oracle Database 10g Release 2 (10.2.0.1.0) for HP-UX Itanium，这个版本的只能安装在主机版本是11.23的机器上，而我目前的操作系统版本却是11.31，所以导致第一次安装进行不下去。

 

 

安装环境的信息：

 

查看内存

# /usr/contrib/bin/machinfo  | grep -i Memory

Memory: 130938 MB (127.87 GB)

 

查看交换空间

# /usr/sbin/swapinfo -a

#

 

 

 

 

2、建立数据库用户及相应的组

----------------------------------------------------

建立组

# groupadd     -g 501      oinstall

# groupadd     -g 502      dba

# groupadd     -g 503      oper

# groupadd     -g 504      asmadmin

# groupadd     -g 505      asmdba

# groupadd     -g 506      asmoper

#

建立oracle用户

#/usr/sbin/useradd -u 501 -d /home/oracle  -g oinstall -G dba,oper,asmadmin,asmdba,asmoper oracle 

查看建立后的情况

#id oracle

uid=501(oracle) gid=501(oinstall) groups=502(dba),503(oper),504(asmadmin),505(asmdba),506(asmoper)

 

3、修改oracle用户的环境变量

指定ORACLE_HOME为/orain/oracle/product/10.2/db_1

数据文件另外要指定在/oracle目录下，这个将会在建立数据库时指定。

#su - oracle

$cd

$ ls -al

total 112

drwxr-xr-x   3 oracle     107           8192 Mar  2 18:55 .

drwxr-xr-x   9 root       root          8192 Mar  1 18:50 ..

-r--r--r--   1 oracle     107            832 Mar  1 16:33 .cshrc

-r--r--r--   1 oracle     107            347 Mar  1 16:33 .exrc

-r--r--r--   1 oracle     107            334 Mar  1 16:33 .login

-rw-r--r--   1 oracle     107           1173 Mar  2 16:56 .profile

-rw-------   1 oracle     107           5084 Mar  2 19:59 .sh_history

drwxr-x---   5 oracle     oinstall        96 Mar  2 18:55 .sw

 

修改.profile文件增加如下内容

$ vi .profile

#--------------------------------------------------------

 export ORACLE_BASE=/orain/oracle

 export ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1

 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32:/usr/local/lib:/usr/lib:/lib

 export PATH=$ORACLE_HOME/bin:$PATH

 export NLS_LANG=AMERICAN_AMERICA.UTF8

 export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"

 export EDITOR=vi

 export ORACLE_SID=oss15

#----------------------------------------------------------

$exit

4、准备安装文件，安装文件打算放在/tmp/hpia64_11gR2_database

#cd /tmp

#mkdir hpia64_11gR2_database

在win7上解压hpia64_11gR2_database_1of2.zip和hpia64_11gR2_database_2of2.zip，右键选择时都解压到当前目录，最后会生成一个database目录，将这个目录整个用ftp工具上传到hp主机/tmp/hpia64_11gR2_database目录。

修改安装文件所在目录的用户及可执行权限：

#chown -R oracle:oinstall /tmp/hpia64_11gR2_database

#chmod -R 775 /tmp/hpia64_11gR2_database

 

如果服务器支持unzip命令可以直接上传zip文件，然后使用以下命令进行解压：

unzip hpia64_11gR2_database_1of2.zip -d /tmp/hpia64_11gR2_database

unzip hpia64_11gR2_database_2of2.zip -d /tmp/hpia64_11gR2_database

 

5、安装数据库

安装时需要使用一个response文件，oracle已经给了模板，可以通过修改模板达到我们所需要的安装特性。

这里模板的路径是：/tmp/hpia64_11gR2_database/database/response

 

修改响应模板文件

#su - oracle

$vi db_install.rsp

#---------------------------------------------------------------------------------------------

以下参数不要更改

oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0

 

oracle.install.option=INSTALL_DB_SWONLY

DECLINE_SECURITY_UPDATES=true

#以下参数根据实际情况更改,一般也无需更改

UNIX_GROUP_NAME=oinstall

INVENTORY_LOCATION=/orain/oracle/oraInventory

SELECTED_LANGUAGES=en,zh_CN,zh_TW

ORACLE_HOME=/orain/oracle/product/11.2/db_1

ORACLE_BASE=/orain/oracle

oracle.install.db.InstallEdition=EE

oracle.install.db.isCustomInstall=true

oracle.install.db.customComponents=oracle.rdbms.partitioning:11.2.0.1.0,oracle.oraolap:11.2.0.1.0,oracle.rdbms.lbac:11.2.0.1.0,oracle.rdbms.dm:11.2.0.1.0,oracle.rdbms.dv:11.2.0.1.0,oracle.rdbms.rat:11.2.0.1.0

oracle.install.db.DBA_GROUP=dba

oracle.install.db.OPER_GROUP=oinstall

#-----------------------------------------------------------------------------------

 

安装开始：

$ ./runInstaller -silent  -ignorePrereq  -force -noconfig -responseFile /tmp/hpia64_11gR2_database/db_install.rsp

Starting Oracle Universal Installer...   Checking Temp space: must be greater than 415 MB.   Actual 4211 MB    Passed Checking swap space: must be greater than 150 MB.   Actual 32768 MB    Passed Preparing to launch Oracle Universal Installer from /tmp/OraInstall2011-03-02_04-58-19PM. Please wait ...$ You can find the log of this install session at:  /orain/oracle/oraInventory/logs/installActions2011-03-02_04-58-19PM.log   # The following configuration scripts need to be executed as the "root" user.  #!/bin/sh  #Root scripts to run   /orain/oracle/product/11.2/db_1/root.sh To execute the configuration scripts:          1. Open a terminal window          2. Log in as "root"          3. Run the scripts          4. Return to this window and hit "Enter" key to continue   Successfully Setup Software.

 

在此安装过程中遇到过两个问题：

 

错误一

$ ./runInstaller -silent -force -noconfig -responseFile /tmp/hpia64_11gR2_database/db_install.rsp Starting Oracle Universal Installer...   Checking Temp space: must be greater than 415 MB.   Actual 4347 MB    Passed Checking swap space: must be greater than 150 MB.   Actual 32768 MB    Passed Preparing to launch Oracle Universal Installer from /tmp/OraInstall2011-03-02_04-46-11PM. Please wait ...$ [SEVERE] - Email Address Not Specified

 

此错误是因为安装模板中少修改了一个参数导致，需要将下面的参数的值修改为true：

DECLINE_SECURITY_UPDATES=true

 

错误二

 

$ [FATAL] [INS-13013] Target environment do not meet some mandatory requirements.    CAUSE: Some of the mandatory prerequisites are not met. See logs for details. /orain/oracle/oraInventory/logs/installActions2011-03-02_04-49-41PM.log    ACTION: Identify the list of failed prerequisite checks from the log: /orain/oracle/oraInventory/logs/installActions2011-03-02_04-49-41PM.log. Then either from the log file or from installation manual find the appropriate configuration to meet the prerequisites and fix it manually.

 

 

这个错误在网上查到说在安装命令中加入选项-ignorePrereq可以解决，但问题的根本原因没有找到。

 

执行脚本建立oratab,dbhome,oraenv,coraenv文件:

 

 

 

# ./root.sh

Check /orain/oracle/product/11.2/db_1/install/root_ynsap02_2011-03-02_17-16-04.log for the output of root script

 

# more /orain/oracle/product/11.2/db_1/install/root_ynsap02_2011-03-02_17-16-04.log

Running Oracle 11g root.sh script...   The following environment variables are set as:     ORACLE_OWNER= oracle     ORACLE_HOME=  /orain/oracle/product/11.2/db_1   Creating /etc/oratab file... Entries will be added to the /etc/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root.sh script. Now product-specific root actions will be performed. Finished product-specific root actions.

 

# more /etc/oratab

# # 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.

#

 

6、静默配置监听

 

 

通过response文件运行netca, 生成sqlnet.ora和listener.ora文件, 位于$ORACLE_HOME/network/admin目录下

#su - oracle

 

$ ./netca /silent /responsefile /tmp/hpia64_11gR2_database/database/response/netca.rsp

Parsing command line arguments:     Parameter "silent" = true     Parameter "responsefile" = /tmp/hpia64_11gR2_database/database/response/netca.rsp Done parsing command line arguments. Oracle Net Services Configuration: Profile configuration complete. Oracle Net Listener Startup:     Running Listener Control:       /orain/oracle/product/11.2/db_1/bin/lsnrctl start LISTENER     Listener Control complete.     Listener started successfully. Listener configuration complete. Oracle Net Services configuration successful. The exit code is 0

 

$ ls -l $ORACLE_HOME/network/admin/*.ora

-rw-r--r--   1 oracle     oinstall       362 Mar  2 17:26 /orain/oracle/product/11.2/db_1/network/admin/listener.ora

-rw-r--r--   1 oracle     oinstall       213 Mar  2 17:26 /orain/oracle/product/11.2/db_1/network/admin/sqlnet.ora

 

查看监听状态：

$ lsnrctl status

到此数据库安装成功。

 

7、静默建库

 

修改响应模板文件：

$ cd /tmp/hpia64_11gR2_database/database/response/

$ vi dbca.rsp

#--------------------------------------------------------------------

#以下参数不要更改

[GENERAL]

RESPONSEFILE_VERSION = "11.2.0"

OPERATION_TYPE = "createDatabase"

#以下参数必须设置

[CREATEDATABASE]

GDBNAME = "ORCL.LK"

TEMPLATENAME = "General_Purpose.dbc"

#以下参数不设置则使用默认值,建议设置

CHARACTERSET = "ZHS16GBK"

TOTALMEMORY = "5120"

#这个是指定数据文件要存放在哪个目录

DATAFILEDESTINATION =/oracle

#--------------------------------------------------------------------

 

开始建库：

$ ./dbca -silent -responseFile /tmp/hpia64_11gR2_database/database/response/dbca.rsp

Enter SYS user password:   Enter SYSTEM user password:   Copying database files 1% complete 3% complete 11% complete 18% complete 26% complete 37% complete Creating and starting Oracle instance 40% complete 45% complete 50% complete 55% complete 56% complete 60% complete 62% complete Completing Database Creation 66% complete 70% complete 73% complete 85% complete 96% complete 100% complete Look at the log file "/orain/oracle/cfgtoollogs/dbca/orcl11g/orcl11g.log" for further details.

 建库后实例检查：

$ ps -ef | grep ora_ | grep -v grep | wc -l
