rhel-6.5_x86-64 Installing Oracle-11.0.2.4 system settings

1. System Kernel parameter setting

Cat >>/etc/sysctl.conf << "EOF" ##### for ORACLE_11GR2 # # # # #fs. Aio-max-nr = 1048576 fs.file-max = 6815744 # ke rnel.shmall=2097152   # Kernel.shmmax=4195057664kernel.shmmni = 4096 Kernel.sem = 32000 Port_range = 9000 65500net.core.rmem_default = 262144 Net.core.rmem_max = 4194304 Net.core.wmem_default = 262144 Net.core. Wmem_max = 1048586EOF

RHEL 6 Shmall and Shmmax are configured to use the default settings, Shmmax is generally set to half of the system memory, 4195057664=4GB

After modification, the Execute command takes effect:

/sbin/sysctl-p

2. Modify User Restrictions

Cat >>/etc/security/limits.conf << "EOF" ##### for ORACLE_11GR2 # # # #oracle soft Nproc 2047oracle hard Nproc 1 6384oracle soft nofile 1024oracle Hard Nofile 65536EOFecho "session    required     pam_limits.so" >>/ETC/PAM.D /login

3. Modify the System configuration file

Cat >>/etc/profile << "EOF" ##### for ORACLE_11GR2 # # # # #if [$USER = "Oracle"]; Then     if [$SHELL = "/bin/ksh"], then ulimit-p 16384 ulimit-n 65536     else         ulimit-u 16384-n 65536     fi fi Eofcat >>/etc/csh.login << "EOF" ##### for ORACLE_11GR2 # # # # #if ($USER = = "Oracle") then     limit Maxproc 16 384     limit descriptors 65536     umask 022 endif EOF

4. Create Oracle user, prepare Oracle installation directory

/usr/sbin/groupadd Oinstall/usr/sbin/groupadd dba/usr/sbin/useradd-m-G oinstall-g dba Oracle echo "Oracle" |PASSWD--s Tdin oraclemkdir-p/opt/oracle/chown-r oracle:oinstall/opt/oracle/chmod-r 775/opt/oracle/  mkdir-p/opt/oraInven Tory chown-r Oracle:oinstall/opt/orainventorychmod-r 775/opt/orainventory

5. Modify the Oracle User profile

Cat >>/home/oracle/.bash_profile << "EOF" ##### for ORACLE_11GR2 # # # # #if [$USER = "Oracle"]; Then    if [$SHELL = "/bin/ksh"], then      ulimit-p 16384      ulimit-n 65536    else      ulimit-u 16384-n 65536

6. Configuring the Hosts File

echo "192.168.0.10 oracle11g oracle11g.local" >>/etc/hosts

7, modify the Rhel version number, complete the Oracle installation and then change back

Sed-i '/red Hat Enterprise Linux Server release 6.5 (Santiago)/s/^/#/'/etc/redhat-releasesed-i ' a Red Hat enterprise Li Nux Server Release 5.0 (tikanga) '/etc/redhat-release

8. Turn off SELinux, firewall

Sed-i '/selinux=enforcing/s/^/#/'/etc/selinux/configsed-i '/#SELINUX =enforcing/a selinux=disabled '/etc/selinux/ Config

Firewall disabled via Rhel graphical management tool, reboot system after completion
