SQL Server 2017 on Linux

Hello, followers, I need to share with you some tips in SQL Server 2017 on Linux

  • SQL Server 2017 supported Red Hat, SUSE and Ubuntu
  • You need 3.25 GB of memory to run SQL Server Enterprise on the Linux operating system
  • Not like Windows Server you can install multiple instances on the operation system, Linux supported only one SQL Server instance
  • Hostname of the SQL server should be less than 15 Characters
  • File System has a different configuration in Ubuntu and SUSE should be EXT4 but in Red Hat should be EXT4 and XFS Files.
  • Remote databases can’t be stored on NFS system
  • SQL Server Native GUI still not supported in Linux system till this moment
  • Cannot connect to the SQL instance on Linux from the management studio installed on Windows Server
  • The maintenance plan, Management Data Warehouse, distributed transactions, and the Data Collector are not supported in SQL Server /Linux
  • If you have SQL version less than 2017 and you need to migrate it to Linux , Recommended to upgrade it on Windows server to SQL 2017 than you can take backup from DB and restore it on Linux or Attach / De attach and in the restore DB from windows to Linux you need to use “WITH MOVE” T-SQL statement
  • SQL Server 2017 unsupported feature on Linux (transactional replication, merge replication, stretch DB, polybase, distributed queries with third-party connections, system extended stored procedures, file tables, CLR assemblies with external access or unsafe permissions set, and buffer pool extensions. Database mirroring, agent alerts, managed backups, the SQL Server browser and the machine learning services that include support for the R and Python programming languages, are also not supported at the time of this recording)

I know this a lot features in SQL Server 2017 not supported in Linux but personally, I am so proud about this results it is the first time for Microsoft to see SQL Server on another operating system (Red Hat, SUSE or Ubuntu)
