How to install Oracle software

If you are not familiar with installing the Oracle software in silent mode, you can use the following articles to learn about its practical application and functions. The following is a detailed introduction of the article.

Sometimes it is inconvenient to log on to the Linux/Unix graphical interface to install the database, and the GUI installation makes it impossible for us to know what operations are actually performed, we can install and delete Oracle software in command mode instead of OUI), create and delete databases instead of dbca ).

Platform: RHEL4.5, Oracle10.2.0.1

1. Upload and decompress the Oracle software. If it is stored in the/home directory

 
 

  
  
$ cd /home  
  
  
$ unzip 10201_database_linux32.zip  
 
 

2. Set the required operating system information for installing Oracle software, such as group, user, system kernel parameters, directory, and user initialization parameters.

Add group and user

 
 

  
  
# groupadd oinstall  
  
  
# groupadd dba  
  
  
# useradd -g oinstall -G dba Oracle  
  
  
# passwd Oracle  
 
 

Modify system kernel parameters

 
 

  
  
# vi /etc/sysctl.conf  
  
  
kernel.shmall = 2097152 
  
  
kernel.shmmax = 2147483648 
  
  
kernel.shmmni = 4096 
  
  
kernel.sem = 250 32000 100 128  
  
  
fs.file-max = 65536 
  
  
net.ipv4.ip_local_port_range = 1024 65000  
  
  
net.core.rmem_default = 1048576 
  
  
net.core.rmem_max = 1048576 
  
  
net.core.wmem_default = 262144 
  
  
net.core.wmem_max = 262144 
 
 

/Sbin/sysctl-p to make the parameter take effect)

Add shell restrictions for Oracle users to improve performance

 
 

  
  
# Vi/etc/security/limits. conf
  
  
Oracle soft nproc 2047
  
  
Hard nproc 16384
  
  
Oracle soft nofile 1024
  
  
Oracle hard nofile 65536
  
  
# Vi/etc/pam. d/login
  
  
Session required/lib/security/pam_limits.so
  
  
Session required pam_limits.so
  
  
# Vi/etc/profile
  
  
If [$ USER = "Oracle"]; then
  
  
If [$ SHELL = "/bin/bash"]; then
  
  
Ulimit-p 16384
  
  
Ulimit-n 65536
  
  
Else
  
  
Ulimit-u 16384-n 65536
  
  
Fi
  
  
Fi
  
  
# Vi/etc/selinux/config invalidates the Secure linux flag)
  
  
SELINUX = disabled
 
 

Create the Oracle_BASE directory

 
 

  
  
# mkdir -p /opt/Oracle  
  
  
# chown -R Oracle:oinstall /opt/Oracle  
  
  
# chmod -R 775 /opt/Oracle  
 
 

Setting the. bash_profile file of an Oracle user

 
 

  
  
# su - Oracle  
  
  
$ vi ~/.bash_profile  
  
  
umask 022  
  
  
export Oracle_BASE=/opt/Oracle  
  
  
export Oracle_HOME=/opt/Oracle/product/10.2.0/db_1  
  
  
export Oracle_SID=WENDING 
  
  
export PATH=$Oracle_HOME/bin:$PATH  
  
  
$ . ~/.bash_profile  
 
 

3. Create an oraInst. loc File

 
 

  
  
$ Su-
  
  
# Vi/etc/oraInst. loc add or modify the following content, where/opt/Oracle is Oracle_BASE)
  
  
Inventory_loc =/opt/Oracle/oraInventory
  
  
Inst_group = oinstall
  
  
# Chmod 664/etc/oraInst. loc
 
 

4. Create a response file. After decompression, the Oracle software's response directory contains various response file templates)

 
 

  
  
# Su-Oracle
  
  
$ Cd/home/database/response
  
  
$ Cp enterprise. rsp enterprise_temp.rsp
  
  
$ Vi required ise_temp.rsp the following parameters must be set)
  
  
UNIX_GROUP_NAME = "oinstall"
  
  
Oracle_HOME = "/opt/Oracle/product/10.2.0/db_1"
  
  
Oracle_HOME_NAME = "OraDb10g_home1"
  
  
S_nameForDBAGrp = "dba"
  
  
S_nameForDBAGrp = "dba"
  
  
N_configurationOption = 3
 
 

5. Running OUI-noconfig through the response file indicates that no configuration assistant is run and only software is installed)

 
 

  
  
$ cd /home/database  
  
  
$ ./runInstaller -silent -noconfig -responseFile /home/database/response/enterprise_temp.rsp  
 
 

After the installation is complete, run root. sh under $ Oracle_HOME as the root user:

 
 

  
  
$ su -  
  
  
# /opt/Oracle/product/10.2.0/db_1/root.sh  
  
  
# exit  
 
 

6. Run NetCA through the response File

 
 

  
  
$ Cd/home/database/response
  
  
$ Cp netca. rsp netca_temp.rsp
  
  
$ Vi netca_temp.rsp if you want to modify the listening name or port here, you generally do not need to modify anything)
  
  
$ Oracle_HOME/bin/netca/silent/responsefile
/Home/database/response/netca_temp.rsp
 
 

After the listener is executed, the listener is started. The above content describes how to install the Oracle software in silent mode. I hope it will help you in this regard.
