Installing Oracle 11gR2 / 12c Database on Linux / Fedora |
Oracle DB 11gR2 Installation needs some kernel parameters changing adding some new packages , so its a little tricky and i thought let me write this one to detail the installation process of Oracle 11gR2 Database on Linux Most Important : Select AL32UTF8 character set in the first screen of installer if you are planning to Install Oracle Fusion Middleware RCU Schemas
Softwares |
You would need 2 zip files p10404530_112030_Linux-x86-64_1of7.zip and p10404530_112030_Linux-x86-64_2of7.zip , you can download this from www.oracle.com under database downloads, extract or unzip to a folder this creates 2 folders by names database , you would need to Merge these two folder without over writing each other
unzip p10404530_112030_Linux-x86-64_1of7.zip unzip p10404530_112030_Linux-x86-64_2of7.zip
for 12c Database
unzip linuxamd64_12102_database_1of2.zip unzip linuxamd64_12102_database_2of2.zip
Edit Host File |
[root@james database]# sudo gedit /etc/hosts
your host file should should look something like this with the machine name added
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.X.Y.Z james james-laptop
all the above in 2 lines
Edit Host File for FMW Install |
[root@james database]# sudo gedit /etc/hosts
your host file should should look something like this with the machine name added
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 james james-laptop ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.X.Y james
all the above in 3 lines
Run the Installer |
First few screens are simple , just click next and next , give the password , the complications come when you see warnings
[james@james-laptop database]$ su Password: [root@james-laptop database]# sudo gedit /etc/hosts
Edit Kernal Parameters |
[root@james-laptop database]# sudo gedit /etc/sysctl.conf
Your parameters should look like this , you can copy paste if needed.
# Useful for debugging multi-threaded applications. kernel.core_uses_pid = 1 # Disable netfilter on bridges. net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 #added by james below lines fs.suid_dumpable = 1 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmni = 4096 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default=4194304 net.core.rmem_max=4194304 net.core.wmem_default=262144 net.core.wmem_max=1048586 kernel.shmmax = 4124653568
Save the Editor and close , set the Parameters
[root@james-laptop database]# /sbin/sysctl -p
Setting Hard and Soft Limits
[root@james-laptop database]# sudo gedit /etc/security/limits.conf
you can copy paste these lines in the Editor, Save and close
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 4096 oracle hard nofile 65536 oracle soft stack 10240 * soft nproc 2047 * hard nproc 16384 * soft nofile 4096 * hard nofile 65536 * soft stack 10240
Now on the Installer Click on Check again button, you would see most Warnings gone , you can also try “Fix and Check again” that will ask you to execute a shell script as root, that should reduce few more warnings.

Missing Packages |
During Operating System many packages might not be installed as required by Oracle Database , its required to add them
[root@james-laptop CVU_11.2.0.3.0_james]# yum install libaio Loaded plugins: langpacks, presto, refresh-packagekit .... Installed: libaio.x86_64 0:0.3.109-5.fc17 Complete!
