SQL Server Always On Availability Groups for SQL Server Linux instances

In this 29th article of the SQL Server Always On Availability Groups series, we configure the AG between SQL Server Linux instances.

Introduction

SQL Server 2017 & 2019 works on the cross-platform operating system: Windows and Linux. You can use SQL Server on Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server, and Ubuntu. You can install it on-premise or cloud solutions such as Azure, AWS.

Environment details

In this article, we create an availability group between two Linux instances. For this purpose, we require two virtual machines in the Oracle VM VirtualBox. You can follow my earlier article SQL Server 2019 on Linux with Ubuntu, and prepare the virtual machines with Ubuntu OS.

I use the following virtual machines in this article:

  • linuxnode2: 10.0.2.51 – Initially, it acts as the primary replica
  • linuxnode3: 10.0.2.50 – Initially, it acts as the Secondary replica
  • Domain Controller and DNS: VDITest3 (10.0.2.15)
  • SSMS client on Windows VM: SQLNode3 (10.0.2.44)

Configure the SQL Server Linux VM’s for static IPs

By default, once you create a virtual machine, it gets a dynamic IP address. The dynamic IP address might change when you reboot the OS. We need to assign the static IP address using the network configuration of Ubuntu.

Connect to the virtual machine linuxnode3, launch terminal and install the ifconfig utility like below. We use the ifconfig command to check the network interfaces and associated IP addresses.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.

Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package

List of Available Database for Current User In SQL Server

Introduction

When working in the SQL Server, we may have to check some other databases other than the current one which we are working. In that scenario we may not be sure that does we have access to those Databases?. In this article we discuss the list of databases that are available for the current logged user in SQL Server
