Installation of SQL Server Analysis Services

This document provides a comprehensive guide to installing SQL Server Analysis Services (SSAS) on your server. SSAS is a business intelligence solution that provides online analytical processing (OLAP) and data mining functionalities for business applications.

Prerequisites

Before you begin the installation, ensure that your system meets the following prerequisites:

A compatible version of Microsoft SQL Server installed.
Sufficient disk space for the SSAS binaries and databases.
Administrator privileges on the server where SSAS will be installed.
Network connectivity if installing on a remote server or requiring access to shared resources.

Installation Steps

Follow these steps to install SQL Server Analysis Services:

Download the SQL Server Installation Media: Obtain the appropriate SQL Server installation media (ISO file or media pack) from Microsoft.
Run the Setup Program: Locate the setup.exe file on the installation media and run it as an administrator.
Choose Installation Type: In the SQL Server Installation Center, select "Installation" and then "New SQL Server standalone installation or add features to an existing installation."
Enter Product Key: If prompted, enter your SQL Server product key.
Accept License Terms: Review and accept the license terms.
Select Features: On the "Feature Selection" page, ensure that "Analysis Services" is checked. You can also select other features if needed.
Instance Configuration: Configure the instance name for Analysis Services. It's recommended to use a meaningful name.
Server Configuration: Configure the service accounts for Analysis Services. For security best practices, it is recommended to use dedicated service accounts.
Database Engine Configuration: For Analysis Services, you will select the mode. Choose between "Multidimensional and Data Mining" or "Tabular".
- Multidimensional and Data Mining Mode: This is the traditional mode for SSAS, supporting OLAP cubes and data mining models.
- Tabular Mode: This mode offers an in-memory columnar database that uses a familiar data modeling approach with tables, rows, and columns.
Analysis Services Configuration: Specify the server mode (Multidimensional or Tabular). You will also need to specify the server administrators. Add the necessary user accounts or groups that will manage the SSAS instance.
Ready to Install: Review the summary of your selections and click "Install" to begin the installation process.
Installation Complete: Once the installation is finished, review the completion report.

Important: After installation, it is highly recommended to apply the latest service pack and cumulative updates for SQL Server to ensure you have the most up-to-date features and security patches.

Post-Installation Tasks

After a successful installation, consider the following tasks:

Configure Firewall: Ensure that firewall rules are configured to allow access to the SSAS instance if it needs to be accessed remotely.
Create Databases: Start creating your Analysis Services databases and populate them with data.
Set Permissions: Configure appropriate security roles and permissions for users and applications accessing SSAS.

Troubleshooting

If you encounter issues during installation, consult the SQL Server Setup log files located in the %Program Files%\Microsoft SQL Server\\Setup Bootstrap\Log directory. Common issues can often be resolved by verifying prerequisites or checking for conflicting software.
