Linting your code, the vanilla way

You may want a linter plugin to lint your code in Vim but you probably don't need it. At least try the built-in way before jumping on the plugin bandwagon.

Defining makeprg

autocmd FileType <filetype> setlocal makeprg=<external command>

This autocommand tells Vim to use <external command> when invoking :make % in a <filetype> buffer. You can add as many similar lines as needed for other languages.

SQL Server Performance Tuning Class - Day 2

Denver 2015

Finding Queries and Bottlenecks

• RECOMPILE hints will cause the sproc to not show up in the DMV (Dynamic Management Views)
• DMVs and profiler will only catch perf issues for a window of time. They are passive tools that have to be running when the issue occurs
• sp_Blitz will look across a wider window of time.
• ClearTrace as scriptable (and more powerful) version of SQL Server Profiler.
• Recommended practice is to create a Tools database to store scripts like ClearTrace and the BrentOzar scripts. May shops will not allow anything to be installed to master. Plus, master won't be restored typically during a rebuild

SQL Server Performance Tuning Class - Day 1

Denver 2015

Getting ready steps

• Write down 3 biggest pain points
  • "IS" it the database that's slowing things down or environmental? Is perfmon the answer?
  • Deadlocks / locking. Should we be running in a differnet isolation mode?
  • Audit solution - triggers vs in-app, etc.
• Gather SQL server stats
• Gather Wait statistics
