4 stars based on 74 reviews

For an instance of SQL Server that includes the Database Engine, Analysis Services, and Reporting Services, each component has a full set of data and executable files, and common files shared by all components. To isolate install locations for each component, unique instance IDs are generated for each component within a given instance of SQL Server. Program files and data files cannot be installed on a removable disk drive, cannot be installed on a file system that uses compression, cannot sql binaries location installed to a directory where system files are located, and cannot be installed on shared drives on a failover cluster instance.

Do not delete any of the following directories or their contents: You can delete other directories, if necessary; however, you might not be able to retrieve any lost functionality or data without uninstalling and then reinstalling SQL Server. Do not delete sql binaries location modify any of the. Sql binaries location are required for SQL Server tools to function properly.

The default is usually drive C. MSSQL for the Database Engine, followed by the major version number, followed by an underscore and the minor version when applicable, and a period, followed by the instance name.

MSAS for Analysis Services, followed by the major version number, followed by an underscore and the minor version when applicable, and a period, followed by the instance name. You can specify any value for the instance ID, but avoid special characters and reserved keywords. Integration Services and client sql binaries location are not instance aware and, therefore are not assigned an instance ID.

By default, sql binaries location components are installed to a single directory: Changing the installation path for one shared component also changes it for the other shared components. Subsequent installations install non-instance-aware components to the same directory as sql binaries location original installation.

After instance renaming is complete, directories and registry keys will continue to use the instance ID created during installation. The registry also maintains a mapping of sql binaries location ID to instance name. Instance ID to instance name mapping is maintained as sql binaries location. The installation path is displayed in Setup only for features with a user-configurable destination folder:.

Changing the installation path for one component also changes it for other components. Subsequent installations install components to the same location as the original installation. When you add features to an existing installation, you cannot change sql binaries location location of a previously installed feature, nor can you specify the location for a new feature. You must either install additional features to the directories already established by Setup, or uninstall and reinstall the product.

For clustered configurations, you must select a local drive that is available on every node of the cluster. When you specify an installation path during Setup for the server components or data files, the Setup program uses the instance ID in addition to the specified location for program and data files.

MSSQL for the Database Engine, followed by the major version number, followed by an underscore and the minor version when applicable, and a period, followed by the instance name.

MSAS for Analysis Services, followed by the major version number, followed by an underscore and the minor version when applicable, and a period, followed by the instance name. MSRS for Reporting Services, followed by the major version number, followed by an underscore and the minor version when applicable, and a period, followed by the instance name.

In the preceding examples, version number 14 is SQL Server The directory structure for a SQL Server named instance that includes the Database Engine and Analysis Services, named "MyInstance", and installed to the default directories would be as follows:.

You can specify any value for the instance ID, but avoid special characters and reserved keywords. Integration Services and client components are not instance aware and, therefore are not assigned an instance ID. By default, non-instance-aware components are installed to a single directory: Changing the installation path for one shared component also changes it for the other shared components.

Subsequent installations install non-instance-aware components to the same directory as the original installation. If an instance of Analysis Services is renamed, the instance ID will not change. After instance renaming is complete, directories and registry keys will continue to use the instance ID created during installation. The registry also maintains a mapping of instance ID to instance name. Instance ID to instance name mapping is maintained as follows:. The installation path is displayed in Setup only for features with a user-configurable destination folder:.

Note that the default drive for file locations is systemdrive , normally drive C. Installation paths for child features are determined by the installation path of the parent feature. Changing the installation path for one component also changes it for other components. Subsequent installations install components to the same location as the original installation.

If you apply an update to any of the instances on the computer, any changes to files in this folder will affect all instances on the computer. When you add features to an existing installation, you cannot change the location of a previously installed feature, nor can you specify the location for a new feature.
