Oracle Installation Prerequisites

Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.

Automatic Setup

yum install -y oracle-database-preinstall-19c

 

Manual Setup

If you have not used the "oracle-database-preinstall-19c" package to perform all prerequisites, you will need to manually perform the following setup tasks.

Add the following lines to the "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf".

fs.file-max = 6815744

kernel.sem = 250 32000 100 128

kernel.shmmni = 4096

kernel.shmall = 1073741824

kernel.shmmax = 4398046511104

kernel.panic_on_oops = 1

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

net.ipv4.conf.all.rp_filter = 2

net.ipv4.conf.default.rp_filter = 2

fs.aio-max-nr = 1048576

net.ipv4.ip_local_port_range = 9000 65500

 

Run one of the following commands to change the current kernel parameters, depending on which file you edited.

/sbin/sysctl -p

 

Add the following lines to a file called "/etc/security/limits.d/oracle-rdbms-server-12cR1-preinstall.conf" file.

groupadd -g 54321 oinstall

groupadd -g 54322 dba

groupadd -g 54323 oper

useradd -u 54321 -g oinstall -G dba,oper oracle

 

Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=permissive

Once the change is complete, restart the server or run the following command.

If you have the Linux firewall enabled, you will need to disable or configure it, as shown here. To disable it, do the following.

# systemctl stop firewalld

# systemctl disable firewalld
