Question: How to install Oralce 11g R2 Database server on Centos 6.x?
Answer:
1-Before to begin you have to download Some dependencies
yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c++ libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel
2-adjust the sysctl.conf
in my case
[root@Oracle ~]# sysctl -p net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key error: "net.bridge.bridge-nf-call-iptables" is an unknown key error: "net.bridge.bridge-nf-call-arptables" is an unknown key kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296
Please change to the standard Oracle values
net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 net.ipv4.ip_local_port_range = 9000 65500 fs.file-max = 65536 kernel.shmall = 10523004 kernel.shmmax = 6465333657 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.core.rmem_default = 262144 net.core.wmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576
3-add users and groups and permissions
# groupadd oinstall #groupadd oper # groupadd dba #/usr/sbin/useradd -u 502 -g oinstall -G dba,oper oracle
# passwd oracle
[root@Pirat9 ~]#vi /etc/pam.d/login # add session required pam_selinux.so open session required pam_namespace.so session required pam_limits.so session optional pam_keyinit.so force revoke session include system-auth -session optional pam_ck_connector.so
[root@Pirat9 ~]#vi /etc/security/limits.conf # add This bellow oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536
[root@Pirat9 ~]#vi /etc/profile # add at the last line if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
Now Switch to a user Oracle
[oracle@Pirat9 ~]$chmod 755 /app/oracle [oracle@Pirat9 ~]$mkdir /app/oracle/app [oracle@Pirat9 ~]$chmod 775 /app/oracle/app [oracle@Pirat9 ~]$mkdir /app/oracle/oradata [oracle@Pirat9 ~]$chmod 775 /app/oracle/oradata
[oracle@Pirat9 ~]$vi ~/.bash_profile # add this to oracle profile
ORACLE_HOME=/app/oracle/11.2.0.2/client ORACLE_BASE=/app/oracle TEMP=/app/tmp/ora TMPDIR=/app/tmp/ora export ORACLE_HOME export ORACLE_BASE export TEMP export TMPDIR export PATH PATH=$PATH:$HOME/bin::$ORACLE_HOME/bin umask 022
Now run the installer and enjoy
