Restoring the SQL Server Master Database

INTRODUCTION

The master database contains records of the structure/configuration for both the current instance and all other databases. When you run sp_configure, you are writing data to the master database. It also contains most of the dynamic management views that are necessary to monitor the instance.

The importance of the master database is crucial. First, it has the information necessary for opening all other databases and has to be opened first. Then, it involves all instance level principals for the current instance.

It is crucial to back up the master database daily. Equally important is to know how to restore the master database to the instance. The most frequent cases are the database crash or the necessity to restore the master database to another instance when no longer use the source instance. In this article, we will examine the specific case of moving the master database to another instance.

CHECK THE STATUS OF APPLICATION SERVICES

Restoring the master database to another instance will involve starting the instance in the single user mode. Thus, it is essential to make sure that the active session is the only one controlling the instance.

For that, stop all application services from accessing the instance, especially if such applications have privileged access. Problems can occur if you start the instance in the single-user mode while the application has already established a session. In this case, you will not be able to proceed with an interactive session from SQL Server Management Studio.

STOP SQL SERVER SERVICES

Stop all SQL Server Services with the SQL Server Configuration Manager: right-click each service and select Stop from the context menu (see fig. 2).

START SQL SERVER IN THE SINGLE USER MODE

To restore the master database, you need the SQL Server instance in the single user mode. Take the following steps:

  1. Open CMD Prompt
  2. Navigate to C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn
  3. Issue sqlservr –m OR NET start MSSQLServer /c /m /T3604

Note that step 2 refers to the Binn directory location. It can be different in your installation.

You can find the necessary directory by checking the Service tab of SQL Server service properties in SQL Server Configuration Manager (See Figure 4):

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.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.
