Editor to share with you how to configure the environment before oracle database installation. I hope you will get something after reading this article. Let's discuss it together.

System version redhat5.6

1. Pre-installation environment configuration

View memory

Grep MemTotal / proc/meminfo

Grep SwapTotal / proc/meminfo

(or free-m checks both memory and swap space, which generally requires 2G of memory and 2G of swap space.)

Modify user's SHELL restrictions, modify / etc/security/limits.conf file

Oracle soft nproc 2047

Oracle hard nproc 16384

Oracle soft nofile 1024

Oracle hard nofile 65536

Oracle soft stack 10240

Modify / etc/pam.d/login file

Session required / lib/security/pam_limits.so

Session required pam_limits.so

Modify the linux kernel, modify the / etc/sysctl.conf file, enter the command: vi / etc/sysctl.conf

Fs.aio-max-nr = 1048576

Fs.file-max = 6815744

Kernel.shmall = 2097152

Kernel.shmmax = 4294967295

Kernel.shmmni = 4096

Kernel.sem = 250 32000 100 128

Net.ipv4.ip_local_port_range = 9000 65500

Net.core.rmem_default = 262144

Net.core.rmem_max = 4194304

Net.core.wmem_default = 262144

Net.core.wmem_max = 1048576

Execute sysctl-p to make the sysctl.conf file effective

Edit / etc/profile to add the following to the file.

If [$USER = "oracle"]; then

If [$SHELL = "/ bin/ksh"]; then

Ulimit-p 16384

Ulimit-n 65536

Else

Ulimit-u 16384-n 65536

Fi

Create related users and groups

Groupadd-g 1000 oinstall

Groupadd-g 1001 dba

Groupadd-g 1002 oper

Useradd-u 1001 oracle-d / home/oracle-g oinstall-G dba,oper

Create a related directory and change the owner of the directory

Mkdir / u01

Chown-R oracle:oinstall / U01

Chmod-R 755 / U01

Set the environment variable .bash _ profile for oracle

Export ORACLE_BASE=/u01/app/oracle

Export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

Export ORACLE_SID=ORA11GR2

Export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin

Install the lazy package under Linux (it is recommended to install it with rpm before trying to use yum)

Configure yum

/ etc/yum.repo.d/yum.repo

[redhat5u6]

Name=redhat5u6

Baseurl= file:///test/Server/

Enabled=1

Gpgcheck=0

Yum clean all

Yum list
