Which Load Balancer is right for you..?

Posted by Sriram Sanka on September 20, 2023


Oracle has Two Load Balancer Services available. , In case if you are not sure which one is best for you and what are the differences, you can refer the following chart provided by Oracle. https://cloud.oracle.com/load-balancers#

Load balancer

The load balancer service provides a reverse proxy solution that hides the IP of the client from backend application server and vice versa. It is capable of performing advanced layer 7 (HTTP/HTTPS), layer 4 (TCP) load balancing and SSL offloading.

Best for: Websites, mobile apps, SSL termination, and advanced HTTP handling.

Network load balancer

The network load balancer service provides a pass-through (non-proxy solution) that is capable of preserving the client header (source and destination IP). It is built for speed, optimized for long running connections, high throughput and low latency.

Best for: Scaling network virtual appliances such as firewalls, real-time streaming, long running connections, Voice over IP (VoIP), Internet of Things (IoT), and trading platforms.

Enable/Disable MFA on Oracle Cloud (OCI) portal

Posted by Sriram Sanka on September 12, 2023


When signing up, it is mandatory to configure and enable Multi-Factor Authentication (MFA). Once configured, during the login process, you will be required to obtain approval either through the Oracle Authenticator App or by obtaining a passcode.

To customise the MFA Configuration, access the Identity & Security section and select the desired domain. This action will direct you to the Domain Dashboard, where you can choose the appropriate security settings and explore additional options for Multi-Factor Authentication.

You can change the Default Configuration under Identity–>Domains–>Default domain–>Security –>MFA, when you try to update the changes , you may get the error as below “You cannot disable these factors as they are being referenced in Rules used in Sign-On Policies. Remove them from the Rules before disabling the factors.”

In order to prevent the occurrence of the aforementioned error, it is advisable to disable the default sign-in policy for both users and administrators as indicated in the error message.

Please note that it is not advisable to disable security policies and multi-factor authentication (MFA) for cloud access. follow https://docs.oracle.com/en-us/iaas/Content/Security/Reference/iam_security_topic-IAM_MFA.htm for more information.

Download Youtube ( Channel ) videos using Python Module – Pytube ,scrapetube.

Posted by Sriram Sanka on April 25, 2023


In this post, I will present the code to download Youtube Individual/Channel Videos step-by-step.

You can download the Videos using pytube module by passing the video URL as an argument. Just Install pytube and run as below.

python -m pip install pytube

This will download the given video URL to your current Directory, what about if you want to store your local copy for your educational purpose when you are offline.? The following will download the all the videos from the given URL to your desired location in the PC.

import requests
import re
from bs4 import BeautifulSoup
from pytube.cli import on_progress
from pytube import YouTube
from pytube import Playlist
from pytube import Channel


def get_youtube(i):
    try:
        yt = YouTube(i,on_progress_callback=on_progress)
        yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first().download('C:\\Users\\Dell\\Videos\\downs\\Sriram_Channel\\')
    except:
        print(f'\nError in downloading:  {yt.title} from -->' + i)
        pass
l = Channel('https://www.youtube.com/channel/UCw43xCtkl26vGIGtzBoaWEw')

for video in l.video_urls:
    get_youtube(video)

You may get regular Expression error in fetching the video information due to changes implemented in the channel URL using symbols. or any other restrictions which are unsupported by the pytube module, either you have to download and install the latest or identify and fix it on your own.

To avoid this, you can use another module called scrapetube

pip install scrapetube

The following code will give you the Video id from the URL provided as input. you need to append ‘https://www.youtube.com/watch?v=’ to mark that as a complete URL.

import scrapetube

videos = scrapetube.get_channel("........t7XvGJ3AGpSon.......")

for video in videos:
    print('https://www.youtube.com/watch?v='+ video['videoId'])

as you can see channel id is the key here, what if you are unaware of channel id.? You can get the channel id either from browser view page source or you can also use “requests” and “BeautifulSoup” module to get the channel ID

import requests
from bs4 import BeautifulSoup

url = input("Please Enter youtube channel URL ")
response = requests.get(url)
soup = BeautifulSoup(response.content,'html.parser')
print(soup.find("meta", itemprop="channelId")['content'])

Instead of using Channel from pytube module, to make it easier lets make changes to the original code snippet posted above, using module “scrapetube.get_channel “

import requests
import re
from bs4 import BeautifulSoup
from pytube.cli import on_progress
from pytube import YouTube
from pytube import Playlist
from pytube import Channel
import scrapetube
import json

def get_youtube(i):
    try:
        print('Downloading ' +i)
        yt = YouTube(i,on_progress_callback=on_progress)
        #print(f'\nStarted downloading:  {yt} from -->' + i)
        yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first().download('C:\\Users\\Dell\\Videos\\downs\\Sriram_Channel\\')
    except:
        print('Error Downloading' +i)
        pass
l = scrapetube.get_channel("UCw43xCtkl26vGIGtzBoaWEw")
for video in l:
    #print('Downloading https://www.youtube.com/watch?v='+ video['videoId'])
    get_youtube('https://www.youtube.com/watch?v='+ video['videoId'])

Hope you like it ! Happy Reading.

Reading Chrome Bookmarks using Python Module chrome_bookmarks

Posted by Sriram Sanka on April 24, 2023


Chrome Browser Bookmark file is in JSON format whereas history file is a database format. One can read the data file using SQLite(DB Browser) to get the URL and downloads data.

In this post I am using chrome-bookmarks module to read the bookmarks and print the URL along with it Name and Folder Information.

Install chrome-bookmarks module using pip

pip install chrome-bookmarks

Now you can read the URL from Python as below.

import chrome_bookmarks
for url in chrome_bookmarks.urls:
    print(url.url)

We Can also print the URL Description/Name as below.

import chrome_bookmarks
for url in chrome_bookmarks.urls:
    print(url.url, url.name)
import chrome_bookmarks

for folder in chrome_bookmarks.folders:
    print(folder.name)
    print(folder.folders)

It is also possible to read the JSON without using the above module.

import json
file ="C:\\Users\\Dell\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\Bookmarks"
with open(file, "r", encoding='utf-8') as bookmarks:
    bookmark_data = json.load(bookmarks)
    print(json.dumps(bookmark_data, indent=1))

Azure ARM Template Validation Tool Kit helps you to validate & meet the Requirements to Publish your Solution to Azure Market Place.

You can Download the Latest Toolkit from https://github.com/Azure/arm-ttk/releases .

  • Download and Extract(unzip) arm-ttk.zip file
  • Start the Power Shell as administrator
  • Navigate to the Extracted Folder/Directory.
  • Unblock the script files Using “Get-ChildItem *.ps1, *.psd1, *.ps1xml, *.psm1 -Recurse | Unblock-File”
  • Import the module using ” Import-Module .\arm-ttk.psd1 “
  • Validate Templates using module “Test-AzTemplate”
Get-ChildItem *.ps1, *.psd1, *.ps1xml, *.psm1 -Recurse | Unblock-File
Import-Module .\arm-ttk.psd1
Test-AzTemplate -TemplatePath \path\to\template

Download and Extract(unzip) arm-ttk.zip file

Start the Power Shell as administrator & Navigate to the Extracted Folder/Directory.

Unblock the script files Using “Get-ChildItem *.ps1, *.psd1, *.ps1xml, *.psm1 -Recurse | Unblock-File”

Oracle Database 21c Express Edition (XE) RPM Installation On Oracle Linux 9

Posted by Sriram Sanka on March 29, 2023


What is Oracle Express Edition

Oracle Database Express Edition (XE) is a community supported edition of the Oracle Database family. It can be Installed in Linux, Windows, Dockers, and Virtual Machine as well.

Oracle Database Express Edition does not restrict in which environment it can be deployed. However, Oracle Database Express Edition is not supported and does not receive any patches, including security patches.

Oracle Database XE supports up to:

  • 2 CPUs for foreground processes
  • 2GB of RAM (SGA and PGA combined)
  • 12GB of user data on disk (irrespective of compression factor)

You can Download Oracle XE from https://www.oracle.com/nl/database/technologies/xe-downloads.html but its not available for Oracle Linux Version 9, In this article we are going install OL8 Version in OL9.

Pre- Installation

1. Make sure to have FQDN(fully qualified domain name) and an Entry with the same in /etc/hosts file.

2. Install dependent rpm compat-openssl10 , This can be downloaded from https://dl.rockylinux.org/pub/rocky/8/AppStream/x86_64/os/Packages/c/compat-openssl10-1.0.2o-4.el8_6.x86_64.rpm
