Known issues

The following sections describe known issues with this release of SQL Server vNext CTP1 on Linux.

General

  • Manually setting the system time backwards in time will cause SQL Server to stop updating the internal system time within SQL Server.

    • Resolution: Restart SQL Server.

  • Some time zone names in Linux don’t map exactly to Windows time zone names.

  • The length of the hostname where SQL Server is installed needs to be 15 characters or less.

    • Resolution: Change the name in /etc/hostname to something 15 characters long or less.

  • SQL Server Engine expects lines in text files to be terminated with CR-LF (Windows-style line formatting).

  • Only single instance installations are supported.

    • Resolution: If you want to have more than one instance on a given host, consider using VMs or Docker containers.

  • All log files and error logs are encoded in UTF-16.

  • SQL Server Configuration Manager can’t connect to SQL Server on Linux.

  • SQL Server Engine has only been tested up to 256GB of memory at this time.

  • CREATE ASSEMBLY will not work when trying to use a file. Use the FROM method instead for now.

Databases

  • Changing the locations of TempDB data and log files is not supported.

  • System databases can not be moved with the mssql-conf utility.

  • When restoring a database backed up on SQL Server on Linux, you must use the WITH MOVE clause in the Transact-SQL statement.

In-Memory OLTP

  • In-Memory OLTP databases can only be created in the /var/opt/mssql directory. If you require more space than what is available at that location, one solution is to mount a drive under var/opt/mssql.

SqlPackage

  • Using SqlPackage requires to specify an absolute path for files. Using relative paths will map the files under the“/tmp/sqlpackage.<code>/system/system32” folder.

    • Resolution: Use absolute file paths.

  • SqlPackage shows the location of files with a “C:\” prefix.

SQL Server Management Studio (SSMS)

The following limitations apply to SSMS on Windows connected to SQL Server on Linux.

  • Maintenance plans are not supported.

  • Management Data Warehouse (MDW) and the data collector in SSMS is not supported.

  • SSMS UI components that have Windows Authentication or Windows event log options do not work with Linux. You can still use these features with other options, such as SQL logins.

  • The SQL Server Agent only supports TSQL-based jobs. Agent functionality in SSMS which relies on other job types do not work on Linux.

  • The file browser is restricted to the “C:\” scope, which resolves to /var/opt/mssql/ on Linux. To use other paths, generate scripts of the UI operation and replace the C:\ paths with Linux paths. Then execute the script manually in SSMS.
