When starting the install of Oracle Database Server there always seems to be a few items that either you are just suppose to know or you spend a day banging your head against the wall trying to figure out what you need to do to get the install up and running.
First item, is creating a database user and group for the install. Do this as the root user:
# groupadd -g 1001 oinstall
# groupadd -g 1002 dba
# useradd -u 1002 -g oinstall -G dba oracle
# passwd oracle
Next, you need to setup X11 forwarding. Modify the /etc/ssh/ssh_config file to allow forwarding: ForwardX11 yes. I personally use BitVise SSH Client and Xming in order to access my SSH environments. In the Xming client, I change the offset to 10 from the default of 0. In the SSH Client, enable X11 Forwarding and set it to 127.0.0.1:10. On the Unix box, install the xauth rpm using yum install xauth. Connect as the oracle user (or psoft) and create the xauthority file, command: xauth add 127.0.0.1:10 . 12345678900987654321123456789009 – you should be able to validate that x11 works by running xclock – if you see a clock, you are golden! If you see the error: Warning: Cannot convert string “” to type XftFont, do a yum install xorg-x11-fonts*
Firewalls can be a bit of a problem, and you will want to make sure that the iptables firewall allows the database to talk to machines that will be connecting to the database. In this example 10.100.120.10 is my application server connecting to the database server 10.100.120.20:
-A INPUT -s 10.100.120.10 -p tcp -m state –state NEW,ESTABLISHED -m tcp –dport 1521 -j ACCEPT
-A OUTPUT -s 10.100.120.20 -p tcp -m state –state ESTABLISHED -m tcp –dport 1024:65535 –sport 1521 -j ACCEPT
RPMs need to installed in order to make the install work correctly, you can manually do everything or you can automate the application by:
# cd /etc/yum.repos.d
# wget https://public-yum.oracle.com/public-yum-ol6.repo –no-check-certificate
# yum install oracle-rdbms-server-11gR2-preinstall
wget https://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle –no-check-certificate
