5. Goals To understand: What is SQL Server 2017
Install and configure on Linux
Running on Docker
What else is new?
What is next?

Currently in Customer Technology Preview (CTP 2.0)
Monthly releases of new features and fixes
Release notes
CTP 1.0 (Nov 2016),…,CTP 1.4 (Mar 2017), CTP 2.0 (Apr 2017)
Lots of new features (beyond just SQL Server on Linux)
non-Production support with Early Adoption Program (EAP)
Describe the purpose, link to source info, release notes, …

7. Where can I run SQL Server 2017?
Windows 64-bit (ISO and CAB)
Linux (supported Linux distributions)
Red Hat Enterprise (RHEL) 7.3
Ubuntu Linux 16.04
SUSE v12 SP2
Azure VM template (RHEL 7.3)
Docker
on Windows Image
on Linux Image
What about macOS, XYZ Distro?
Not planned for support but likely to work or use Docker
Windows 64-bit (ISO and CAB) -
Linux (supported OS packages)
Red Hat Enterprise (RHEL)
Ubuntu Linux
SUSE v12 SP2 -
Azure VM template (RHEL 7.3) -
Docker
on Windows Container -
on Linux Container -
macOS – use Docker

8. How does SQL Server run on Linux?
SQL Server Operating System (SOS/SQL OS)
Internal abstraction layer for tasks, schedules, memory,…
Drawbridge project
MSFT Research late 2011
Application sandboxing – isolating, picoprocesses, library OS,…
SQL Platform Abstraction Layer (SQL PAL)
Started with SQL 2005 design
Reference

9. How does SQL Server run on Linux?
Started with SQL 2005 design
Reference
Outcome: Effectively the same compiled code for Windows runs on Linux

10. SQL Server on Linux Minimum system requirements:
4 GB memory (tested up to 1TB to date)
2 GB disk space minimum
Supported file systems:
ext4 or xfs

11. SQL Server on Linux - Demo
Install & config
mssql-server
command-line tools
Sql server agent
Restore a database

12. SQL Server on Linux - Administration
Configuration – Port, SA password, default paths, traceflags
/opt/mssql/bin/mssql-conf list /opt/mssql/bin/mssql-conf set network.tcpport 1433
Service control – systemd service manager
systemctl enable mssql-server
systemctl disable mssql-server
systemctl start mssql-server
systemctl stop mssql-server
systemctl status mssql-server
Logging
Default path for errorlog, XE - /var/opt/mssql/log
syslog by default for SQLPAL, so make sure to monitor

13. SQL Server on Linux - Administration
Use Linux commands* for admin functions
df – mounted file system free space & usage
du – used space for given directory
top/htop - displays process and resource usage
ps – active processes chown/setfacl – file ownership/acl’s …
* General Linux admin support links in the slide notes

14. SQL Server on Linux – High Availability
Shared-disk clustering using Pacemaker
Pacemaker != WSFC
Availability Groups
All features supported
Read-only routing
Auto-seeding
Distributed/subnets
Failover options

15. SQL Server on Linux - Performance
Hardware/virtualization and OS vendor recommendations
Storage configuration & separation rules still apply
Tempdb, data, log, …
Kernel tunables (sysctl):
vm.swappiness = 10?
vm.dirty_reads
fs.file-max …
Check out TPC-H support documents for SQL on Linux submission
SQL configuration practices: max server memory, MAXDOP, trace flags,…
ALWAYS BASELINE, CHANGE & TEST AGAIN!

16. Machine vs OS Virtualization (containers)
What is Docker?
Machine vs OS Virtualization (containers)

17. Why Docker? Resource efficiency – shared OS
Manage apps side-by-side in isolation – higher density
Not a new concept (FreeBSD Jails, Solaris Zones,…)
Easy container management
Portable
Ready-to-run containered applications
Ability to create your own
Integration into DevOps world
Puppet, Chef, Vagrant, Ansible,…

18. Docker - Terminology Images – collection layered file system changes
Does not have state and never changes
Registry – hosting service of images
100,000 apps on Docker Hub
Containers – runtime instance of an image
Layered filesystem
Data Volumes - persisted
Network port bindings

19. SQL Server Docker - Images
Two different base-images: Linux and Windows
Github -
Requirements
Docker Engine 1.8+
Min 4 GB disk
Min 4 GB memory

20. SQL Server Docker - Demo
Docker commands
Pull mssql-server-windows image
Create a container, mapping port and data volume
Restore a database
Create more containers, using “attach_dbs”

21. SQL Server Docker – Administration
Management tooling options:
Kitematic – Desktop UI interface to Hub
Rancher - Orchestration
Shipyard – Cluster management
Deployment:
Windows Server 2016
Azure – PaaS and IaaS options
Resource allocation:
CPU shares
Specific cores
Memory limit

22. SQL Server 2017 - What else is new?
Lots of Community driven enhancements!
Smarter backup information – sys.dm_db_file_space_usage has modified_page counts
SELECT INTO … ON FILEGROUP! – keep your staging separate
Tempdb per-user database usage information
VLF DMF - sys.dm_db_log_info()
Sockets, cores per, numa_node_count - sys.dm_os_sys_info
Improved small database backup performance

23. What else is new? – Part 2
Resumeable online index rebuilds – pause, continue
Graph Processing – represent complex relationships with NODES and EDGE tables, and the new MATCH operator
LOB support in Clustered Columnstore indexes
Adaptive JOINS – dynamic switching of joins during query execution
Query store wait stats – query level wait information
Automatic Tuning – query store analysis and automation recommend and fix identified problems

24. What else is new? – Part 3 Reporting Services Stand-alone install
Power BI hosted reports
Analysis Services
Ragged Hierarchy members
Detail row – custom row sets definable in the drill-down
Tabular table-level security
Machine Learning (formerly R Services)
Python language support

25. What else is new? - Demo T-SQL focused fun!
BULK INSERT … FORMAT = ‘CSV’
TRIM(), TRANSLATE(), CONCAT_WS()
Graph functionality
MovieLens dataset -
Full: 24,000,000 ratings and 670,000 tag applications applied to 40,000 movies by 260,000 users. Includes tag genome data with 12 million relevance scores across 1,100 tags. Last updated 10/2016.

26. What is next? More features coming, but bigger items:
Cross-platform, community open sourced, management UI
AD authentication on Linux – host must be AD joined (realmd)
