High level features of Azure Machine Learning

Hi All


In our previous article we “Starting with Azure Machine Learning” we created a free Microsoft Machine Learning account. If you haven’t done that, please create your own free ML account so you can practise and understand this article further. If you have an account already created and we are all good to go.


Azure Machine Learning Studio is a GUI-based integrated development.


Our next step is to understand very high level Azure ML options. Below are high level feature in Azure ML followed by understanding of each high level feature:


Projects: As you can see in the screenshot, Projects is a newly added feature to Microsoft Azure Machine Learning. An individual can work on multiple dataset, Notebook and experiment for different clients/projects. Unless we use a proper naming convention, it was difficult to understand which dataset is associated to which project/client. To resolve this issue, Projects was introduced so that we can consolidate all information related to single project in same location. I would say Projects was a very small change to Azure ML but it has a very big Impact.


Experiments: This is the brain and heart of Azure ML. Experiments is where we create new models and train our model on smaller data. We can iterate on our model design, editing the experiment and running it until it gives us the results we looking for. Experiments in Azure ML is a showcase for simple experiments that make it easier for someone who wants to start exploring machine learning, through datasets. We would be spending nearly 70 % of our time in Experiments by using different features like data format conversions, data input and output, feature selection, etc. Below is screenshot of same:


Web Services : When our model is ready, we can publish it as a web service so that others can send it new data and get predictions in return. This is a very important feature in Azure ML and we will discuss a lot about this feature in our upcoming articles.


NoteBooks : As you can see in the screenshot, Notebooks is a newly added feature to Microsoft Azure Machine Learning. As we have already seen and discussed, Azure ML is GUI based, drag and drop simple to use ML platform however we have lot of other platform which are non GUI base. Azure ML Notebooks is create to encourage those who still want to continue writing code. We can create a machine learning model in a notebook by writing the code and implementing the machine learning API.


Datasets: The first and the foremost thing we need in Machine Learning is data. Azure ML offers several sample datasets which are part of Machine Learning Studio. We ca use it or we have option to import data from many sources like from our local machine. Very common dataset formats are GenericCSV, Attribute-Relation File Format (ARFF), GenericTSV, DataTableDotnet, etc


Trained Models : We can say that trained Model is a part of web services. When our model is ready, we can publish it as a web service so that others can send it new data and get predictions in return. Similarly, I can use this trained models for my other dataset without publishing it and use it within same workspace. This is a very important feature in Azure ML and we will discuss a lot about this feature in our upcoming articles.


Settings: Workspace name, storage, account information, users, data gateways and Authorization tokens are options available in settings. This is just like any other settings available in applications.


I will explain uses of each and every High level feature and talk more in details about them in my upcoming articles.


Happy Learning!!

Starting with Azure Machine Learning

Hi All,


Today we create a Machine Learning account and will have a glance of very basics of Microsoft Machine Learning. Well machine learning in general helps to predict things based on its learning from data provided, for instance the weather, route you around traffic jams, and display personalized ads on your web pages. Throughout my upcoming articles we will learn how to use Azure machine learning in order to create, deploy, and maintain predictive solutions.


I will try to share my experience with Machine Learning data which issues I faced, solutions we used to resolve our issues. My aim to publish as many articles as possible to share everyday problems and solutions I go through and help you if you face same issues or similar issues with your experiment. So let’s get started with an experiment and ML.


To start with, we will create a free Microsoft Machine learning account. How do we create the same follow below steps:

  1. Create a new Microsoft live account from URL https://signup.live.com/
  2. Browse Site https://studio.azureml.net/
  3. Click on “Sign up Here
  4. Select “Sign In” which says “Free Workspace”.
  5. Once you Sign in with your account, you will have a Free Azure ML subscription ready to use.


So congratulation, you now have a Microsoft Azure Machine Learning account created with just 5 simple steps and less than 10 mins.

Advantages of this account is:

a.  Currently this is a life time free account from Microsoft

b. You get free 10 GB of storage space which can be used for data processing.

c. You get R and Python scripts support

d. You will Predictive web services support


Now, I would like you to go through below options like Project, experiment, Web services, etc to understand what they are. I will go through all of them one by one and explain each one of them in detail in my upcoming articles.

MySQL server Replication

Hello Everyone,

Today we are doing mysql replication, for Mysql installation you can refer my previous blogs

for this setup we need to VM installed Mysql, server which contain primary DB will be “Master” & server which has replica of the DB know as a “Slave”

lets start the replication.


Configure MySQL Master

1) Need to edit “/etc/my.cnf”

server-id = 1
binlog-do-db=otrs #dbname
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/mysql-relay-bin.index
log-error = /var/lib/mysql/mysql.err
master-info-file = /var/lib/mysql/mysql-master.info
relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
log-bin = mysql-bin

2) Restart the mysql service

# service mysqld restart

3) create a Slave user and password. For instance

[root@OtrsMaster ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 17
Server version: 5.1.73-log Source distribution

affiliates. Other names may be trademarks of their respective
Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.


mysql> STOP SLAVE;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> GRANT REPLICATION SLAVE ON *.* TO ‘centos’@’%’ IDENTIFIED BY ‘centos’;
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)

5) Applied Read only lock on slave

Query OK, 0 rows affected (0.00 sec)

| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
| mysql-bin.000001 | 106 | otrs | |
1 row in set (0.00 sec)

6) Note down the file (mysql-bin.000001) and position number (106)

7) Backup Master server database

# mysqldump –all-databases –user=root –password –master-data > masterdatabase.sql

8) After taking the backup Again login to MySQL as root user and unlock the tables

Query OK, 0 rows affected (0.01 sec)
mysql> quit

9) Copy the masterdatabase.sql file to your Slave server using SCP
scp masterdatabase.sql root@

Configure MySQL Slave

1) Need to edit “/etc/my.cnf”
server-id = 2
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/mysql-relay-bin.index
log-error = /var/lib/mysql/mysql.err
master-info-file = /var/lib/mysql/mysql-master.info
relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
log-bin = mysql-bin
innodb_buffer_pool_size = 256M
innodb_log_file_size = 512M

2) Import the master database:

mysql -u root -p < /root/masterdatabase.sql

3) # service mysqld restart

4) Log in to the MySQL & run the below commands

mysql> SLAVE STOP;
Query OK, 0 rows affected (0.01 sec)
mysql> CHANGE MASTER TO MASTER_HOST=’′, MASTER_– USER=’centos’, MASTER_PASSWORD=’centos’, MASTER_LOG_FILE=’mysql-bin.000001′, MASTER_LOG_POS=20249;
Query OK, 0 rows affected (0.03 sec)

Query OK, 0 rows affected (0.01 sec)

Last_SQL_Errno: 0
1 row in set (0.00 sec)

If your application & DB server are the same then installed the application on slave server before adding in to it Mysql Slave.

& rsync your application folders with slave server in scenario you will get Mysql replication as well as application  server

[root@OtrsMaster ~]# crontab -l
*/10 * * * * /usr/bin/rsync -avr –progress –delete //var/article/* root@ 

Fail-over Master to slave

1)flush log if server was master after booting you have to run below command
mysql> flush logs;
Query OK, 0 rows affected (0.01 sec)

mysql> SLAVE STOP;
Query OK, 0 rows affected (0.01 sec)
Query OK, 0 rows affected (0.01 sec)

Query OK, 0 rows affected (0.01 sec)
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
| mysql-bin.000001 | 20425 | | |
1 row in set (0.00 sec)

After doing all these settings restart the applications services

[root@OtrsMaster ~]# /etc/init.d/httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]

To make failed server (after rebuilding) again MySQL slave please follow “Configure MySQL Slave” section.



Configure Office Web App 2013 Farm with SharePoint 2013 Farm


Hi Friends,


Today we will discuss on how to configure Multi Server Office Web Apps farm with a SharePoint farm. Also the specialty of this OWA configuration is that it can work inside and outside of firewall. Normally OWA farms are setup HTTP inside the firewall network(Internal network) and HTTPS outside the network(External world) but using this configuration we will configure HTTPS for both inside and outside network. This will not only decrease additional overhead and configuration but also is recommended by Microsoft to use HTTPS for production environment.


We need to meet below pre-requisites before we proceed further:
1. SharePoint farm configured and ready to use
2. Two or more Office Web Apps servers with setup files
3. One certificate for Office Web App
4. If you are using Windows server 2012 R2 then you would need to install latest update for Office Web Apps
5. FQDN name for your Office web app farm e.g.(owa.domain.com) and its DNS entry with Round Robin(You can also configure Windows NLB or a Load Balancer entry for same)

Installation of Office Web App is very simple, You just need to download the installable and execute it on all OWA servers.

Install Office Web apps on all Office Web Apps servers. If you are using Office Web App on Windows Server 2012 R2, you should install latest update for Office Web Apps. You would need an Office Web app certificate imported to IIS
Now Let’s configure Office Web App, Open Windows PowerShell and execute below command

Once the Office Web App farm is configured, open IIS and make sure SSL binding for site HTTP80 has proper certificate attached.

From IIS binding select the certificate and export the .cer file.
You need to import it to central admin manage trust.

To Attach this Office web app farm to SharePoint farm, you need to create a WOPI connection. Open SharePoint PowerShell on SharePoint server and execute below command:

New-SPWOPIBinding -ServerName “officewebapp.domain.com”

Set Wopi zone

Now if you want to add other Office Web App Server to OWA farm, you need to execute below command on existing OWA server
new-officewebappsmachine -machinetojoin “owa2server.domain.com”

Hope this will help you

Configure Workflow Manager 1.0 with SharePoint Server 2013

Hi Friends,

Today we will discuss on how to configure Multi Server Workflow farm with SharePoint farm. Just of your information, you need to access Workflow farm only from WFE and Application servers. This means just like your database server, even workflow servers are not exposed to end users.

We need to meet below pre-requisites before we proceed further:
A. SharePoint farm configured and ready to use
B. Two or more Workflow servers with setup files
C. If you are using Windows server 2012 R2 then you would need update KB2799752(Service bus hotfix) and KB2799754(Workflow manager hotfix)
D. FQDN name for your workflow farm e.g.(Workflow.domain.com) and its DNS entry with Round Robin(You can also configure Windows NLB or a Load Balancer entry for same)

  1. Let’s get started with installation of Workflow Manager 1.0 on Workflow servers. We need installable as shown below

  2. When you will try to install the workflow.exe file you will be asked to download and install WebPlatformInstaller.exe. Now all the updates and most components are installed through WebPlatforminstaller.





  1. Once the WebPlatforminstaller is installed, you need to search for Workflow manager and Workflow manager client and install the same.








  1. Once Workflow Manager and client is installed, I would suggest you to install the updates as well.








  1. Now let’s configure Workflow Server farm. This is very important so please follow steps carefully.
  2. Lets execute the Workflow Manager Configuration Wizard
  3. Select “Configure Workflow Manager with Custom Settings”

  4. Now provide the SQL server instance name, Authentication, Certificate and SQL Workflow database names

  5. You need to provide the Workflow service account credentials which will be used to connect to SQL server and for workflow IIS Application pool.

  6. You would need to provide a Certificate Generation Key. It is just like Passphrase for your SharePoint farm

  7. Make sure you select “Allow workflow management over http on this computer”

  8. Along with Workflow Management, you need to configure Service Bus required by Workflow manager

  9. Make sure you select “use the same certificate generation key as provided for workflow manager”


  1. Once the Workflow Farm is created, you need to join other Workflow server to the farm. To do so execute the same Workflow configuration wizard and select “Join an Existing Workflow Manager Farm”

  2. Provide the existing Workflow Farm SQL server instance name, Workflow database name and Service Bus farm database name

  3. Provide the workflow service account and Certificate generation key used while creating workflow farm.

  4. Select “use the same service account credentials as provided for Workflow Manager”, then select next

  5. Once farm other server is joined to workflow farm you will see below

  6. Once workflow is configured, you need to attach Workflow Farm to SharePoint farm. Make sure you have DNS entry(Workflow.domain.com) for your Workflow farm. If not DNS, you should at least have Host entry for same. Try to browse http://workflow.domain.com:12291 on WFE and Application server, you might see Authentication error.

  7. Add the URL to Local Intranet and set the Local Intranet zone to “Automatically login with current username and password”


  1. Now you should be able to browse the workflow farm details, this shows you can connect to workflow farm and it is working fine.

  2. Now execute below command in SharePoint Powershell
    Register-SPWorkflowService -SPSite “http://sharepointsite” -workflowHostUri “http://workflow.domain.com:12291/” -AllowOauthHttp -ScopeName SharePoint –force

  3. Now you need to activate the workflow feature on site
    Enable-SPFeature -Identity WorkflowServiceStore –Url http://sharepointsite

  4. In Central Admin > Manage Service Application > Workflow Service Application Proxy

  5. Open site in SharePoint designer – Select workflow from left pane – select new workflow
    A. Workflow farm can co-locate on SharePoint servers
    B. As per Microsoft articles, for high availability you need to have at least 3 Workflow Server in farm. You cannot have 2 workflow servers in a farm. It has to be 1 or 3.

SharePoint 2016 Farm configuration issue on Windows Azure Virtual Machine

Hi All,
I hope you all know that now we can create a SharePoint 2016 VM on Windows Azure. In case you have not tried it yet, you can follow below:

Select New on Windows Azure > Compute > Virtual Machine > From Gallery > Select SharePoint from left hand navigation > Select SharePoint Server 2016 IT preview
While I was working with this VM, I came across an issue where I was unable to configure a SharePoint 2016 farm using the SharePoint 2016 VM created in Windows Azure using one of their template. I found that root of issue was Active Directory. SharePoint cannot work without active directory and not everyone using Azure creates a VM with AD in Windows Azure itself. If you plan to create an AD forest in Azure and then add SharePoint 2016 VM to that domain, please follow my article:

Creating a Lab on Windows Azure


If you are planning to use this VM only for learning purpose then you may want to create a SharePoint farm without Active Directory. Unlike previous versions of SharePoint, you cannot use Single Server install model to create a SharePoint farm without Active Directory or without installing SQL server.




To overcome this issue you need 1st install SQL Server and then use below PowerShell command to configure your SharePoint farm. You can download SQL server from below link



Once SQL server is installed and your local admin account has access to SQL server, you can use SharePoint PowerShell to create tour SharePoint 2016 Farm.
1. Open SharePoint PowerShell as Admin
2. You may want to type below command and provide actual values. When you execute the command, you will be requested for credentials of your local admin account you used while creating this Virtual Machine.
New-SPConfigurationDatabase -DatabaseName “SP2016_config” -DatabaseServer “Name of SQL Server” -Passphrase (ConvertTo-SecureString “Sharepoint@2016” -AsPlainText -force) -LocalServerRole SingleServerFarm -FarmCredentials (Get-Credential)


Note: I have observed that when people try to copy paste such commands, hyphen(-) sign does not work, so remove and add these sign again in whole command.

Once above command is executed successfully without any issue, you can execute SharePoint PSconfig wizard and complete SharePoint farm configuration.

Hope this will help you.
