Users can still generate memory dumps manually when automatic core dump is disabled coredump. There are two options for controlling the type of memory dumps that SQL Server collects: coredump.

These relate to the two phases of core dump capture. The first phase capture is controlled by the coredump. The second phase is enabled when the coredump.

Any user on the computer can create a database using an instance of LocalDB, store files under their user profile, and run the process under their credentials.

By default, access to the instance of LocalDB is limited to its owner. The data contained in the LocalDB is protected by file system access to the database files. If user database files are stored in a shared location, the database can be opened by anyone with file system access to that location by using an instance of LocalDB that they own.

If the database files are in a protected location, such as the users data folder, only that user, and any administrators with access to that folder, can open the database. LocalDB always runs under the users security context; that is, LocalDB never runs with credentials from the local Administrator's group.

This means that all database files used by a LocalDB instance must be accessible using the owning user's Windows account, without considering membership in the local Administrators group. SqlLocalDB Utility. Skip to main content. This browser is no longer supported.

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.

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.

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.

For example,. The registry also maintains a mapping of instance ID to instance name. Instance ID to instance name mapping is maintained as follows:.
