Software Needed:

We can download these from official Oracle website (https://edelivery.oracle.com/osdc/faces/SoftwareDelivery_ ).

1. Grid Infra (Including cvuqdisk utility)
2. Oracle Database 19c
3. Oracle database and grid RU patches from Oracle Support Patch download section ( https://support.oracle.com/knowledge/Oracle Cloud/19202304_9.html )

Downloading Grid Infra (Oracle Restart) & Oracle Database 19.3.0.0 version from edelivery location as shown in picture here.

Note : edelivery has WGET options as well to download softwares, in case if WGET is a viable option to download.

Note : You should not download Oracle HTTP Server 12.2.1.3.0 from list.

• Create a folder

• Copy WGET script from download page onto the server in that folder as WGET_1.sh

• Change script permission to 755

  chmod 755 WGET_1.SH
  

• WGET will download all files into one folder.

Downloaded files are listed here:

• V982063-01.zip - Oracle Database
• V982068-01.zip - Grid Infra (ASM, Oracle Restart)

Installation of ASM Binaries:

Installation Steps:

We need to update system first:

sudo su -
yum update

Installing Pre-Instllation requirements using YUM:

sudo su -
yum install oracle-database-preinstall-19c

Setting up Oracle User and its group

Since already we have executed pre-installation package, these users and group would already be there.

Verify, if not created:

id oracle

It should return like :

uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba)

Switch you login to Root:

su -

## Incase if pre-install has not worked and oracle user has not created:
groupadd oinstall
groupadd dba
groupadd oper
groupadd backupdba
groupadd dgdba
groupadd kmdba

useradd -m -g oinstall -d /home/oracle oracle
usermod -a -G dba, oper, backupdba, dgdba, kmdba  oracle


## These groups to be created:
groupadd asmadmin
groupadd asmdba
groupadd asmoper
groupadd osoper


usermod -a -G asmdba,osoper oracle
useradd -u 54323 -g oinstall -G asmadmin,asmdba,asmoper grid

Create OFA folders for installations:

## For Oracle user
mkdir -p /u01/app/oracle/product/19.0.0/db_1

## For Grid user
mkdir -p /u01/app/grid
mkdir -p /u01/app/19.0.0/grid

chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle

chmod -R 775 /u01

Login to oracle to set environment Oracle Database

• su - oracle

backing up existing .bash_profile

• mv ~/.bash_profile ~/.bash_profile_org

Use vi editor with .bash_profile to create below lines:

vi .bash_profile

Unzipping downloaded files of database using oracle user:

Unzipping downloaded files of Grid Infra using grid user:

• Grid Infra

  su - grid
  unzip V982068-01.zip -d /u01/app/19.0.0/grid
  

• Database Unzip

  unzip V982063-01.zip -d /u01/app/oracle/product/19.0.0/db_1

Swtich login to Root:

• su -

Install Oracle ASMLib Package

yum install oracleasm-support
yum install kmod-redhat-oracleasm
yum install oracleasmlib-2.0.17-1.el8.x86_64.rpm

In case yum install is not working for oracleasm-support, download it from Oracle Linux 8 Yum repository .

On this page, search for "oracleasm-support"

You can download ASMLib 2.0 from Oracle ASMLib page :

Once the installation done, proceed to it's configuration:

• oracleasm configure -i

We need to answer few questions asked by this configurator.

  Default user to own the driver interface []: grid
  Default group to own the driver interface []: oinstall
  Start Oracle ASM library driver on boot (y/n) [n]: y
  Scan for Oracle ASM disks on boot (y/n) [y]: y

Switch back to root user:

Need to perform some task which is required Root user's permission.

Updating Kernel Parameters

Note: If pre-install package did not work, this work to be done manuall.

Kernel parameters are to be updated as per Oracle documentations. Below parameters value to be set. We have two ways to update this. Create another file in folder system.d starting with any number for example:

99-oracle-database-sysctl.conf

Open the file and update values:

 fs.aio-max-nr = 1048576
 fs.file-max = 6815744
 kernel.shmall = 2097152
 kernel.shmmax = 4294967295
 kernel.shmmni = 4096
 kernel.sem = 250 32000 100 128
 net.ipv4.ip_local_port_range = 9000 65500
 net.core.rmem_default = 262144
 net.core.rmem_max = 4194304
 net.core.wmem_default = 262144
 net.core.wmem_max = 1048576

To apply changes in kernel parameters :

 sysctl -p

Note: A reboot may require if the changes does not refelect

Other packages required for this installation

Two more packages to be installed.

 yum install ksh
 yum install libaio-devel.x86_64
