For partitioning, see the Creating a Separate Partition for Data (block) Storage section in the Installation Guide.

Rename all the repos under the directory /etc/yum.repos.d/

mv /etc/yum.repos.d/oracle-linux-ol8.repo /etc/yum.repos.d/oracle-linux-ol8.repo_bkp
mv /etc/yum.repos.d/uek-ol8.repo /etc/yum.repos.d/uek-ol8.repo_bkp
mv /etc/yum.repos.d/virt-ol8.repo /etc/yum.repos.d/virt-ol8.repo_bkp

Create the /etc/yum.repos.d/ocsm.repo with the following content:

[OCSM]

baseurl=ftp://<REPO_SERVER_IP>/pub/ocsm/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=0
enabled=1
proxy=_none_

Run this command to clean-up the repo:
yum clean all

Run this command to verify the repolist:

yum repolist

# yum repolist

repo id  repo name
OCSM     OCSM dependencies

Copy the following from the repo server to the Session Monitor server in the temporary directory, such as /tmp/dependency/ and install those RPMs on Session Monitor server in this order.
```
yum install perl-IO-Socket-SSL-2.066-4.module+el8.6.0+20623+f0897f98.noarch.rpm
perl-Mozilla-CA-20160104-7.0.1.module+el8.3.0+21136+b437fca9.noarch.rpm
perl-Net-SSLeay-1.88-2.module+el8.6.0+20623+f0897f98.x86_64.rpm
```
Install the MySQL RPM files using the following command:
```
yum install mysql-commercial-*
```
Copy the following RPMs from the Repo server to the Session Monitor server in a temporary directory, such as /tmp/dependency/, and install the RPM files on the Session Monitor server in this order:
1. rpm -ivh python39-setuptools-wheel-50.3.2-4.module+el8.9.0+90016+9c2d6573.noarch.rpm
2. rpm -ivh python39-pip-wheel-20.2.4-8.module+el8.9.0+90016+9c2d6573.noarch.rpm
3. rpm -ivh python39-libs-3.9.18-1.module+el8.9.0+90071+8dc52a4f.x86_64.rpm
4. rpm -ivh python39-3.9.18-1.module+el8.9.0+90071+8dc52a4f.x86_64.rpm
5. rpm -ivh python39-pip-20.2.4-8.module+el8.9.0+90016+9c2d6573.noarch.rpm
6. rpm -ivh python39-pyyaml-5.4.1-1.module+el8.9.0+90016+9c2d6573.x86_64.rpm
Download the following protobuf package from https://pypi.org/project/protobuf/3.20.3/#files to a temporary directory, such as /tmp/dependency/ of the Session Monitor Server:
```
protobuf-3.20.3-cp39-cp39-manylinux_2_5_x86_64.manylinux1_x86_64.whl
```
Download the following MySQL Connector package from MOS to the same temporary directory used above. such as /tmp/dependency/ directory of Session Monitor Server:
```
MySQL Connector 8.0.33 Package: p35301971_800_Linux-x86-64.zip
(Patch 35301971: MySQL Connector/Python 8.0.33 WHL for portable Linux x86 (64bit) Python 3.9)
```
Note:
The Session Monitor dependencies used here are based on MySQL Connector 8.0.33 version since we are using MySQL 8.0.34 version. If there are any additional dependencies required, please take that as well.
Run this command to set Python alternatives to python 3.9:
```
update-alternatives --config python3
update-alternatives --config python 
```
Note:
After the Session Monitor upgrade, while installing any new packages using yum, some packages will install Python 3.6 as a dependency. As a result, Python alternatives will be getting changed. This can cause unexpected problems in the Session Monitor functionality. So, it is mandatory to verify that Python is pointing to Python 39. Run the commands listed above after installing every package using yum.

Note:
When prompted, select the number corresponding to python3.9 option and press the Enter key on the keyboard.
Run the following commands to install MySQL Connector from the temporary directory, such as /tmp/dependency/:
```
cd /tmp/dependency/
yum install unzip
unzip p35301971_800_Linux-x86-64.zip
pip3 install mysql_connector_python-8.0.33-1commercial-cp39-cp39-manylinux1_x86_64.whl --no-index --find-links=/tmp/dependency/
```
Note:
In the pip3 command used above, the option "--find-links" points to the directory where the dependencies required for the MySQL Connector whl file is present. Here, protobuf package is a dependency for MySQL Connector and is present in the temporary directory, such as /tmp/dependency/ as mentioned in the previous steps.
Run this command to install Session Monitor:
```
yum install ocsm
```
For adjusting the firewall access, see the section Tasks to be Performed after RPM Installation in the Session Monitor Release 5.2 Installation Guide.
