About this talk...
... or why should you be here?

Two choices - Get frustrated, angry, etc. - Embrace the opportunity to learn

“By the end of this day, I’ll either have smashed my computer against the wall, or will have become a better human being”
/me to a colleague during an emergency case involving Windows and a web based remote access system

So let’s embrace this opportunity

Rough agenda...
- Biggest differences
- How to feel (more) at home
- Percona Toolkit: what works, what doesn’t?
Focus on plain MySQL (not NDB or Galera)

Biggest differences
Wednesday, November 6, 13
Case sensitivity
- Though identifiers must be consistent on the same statement
select a from tbl where A=1 -- won’t work
Wednesday, November 6, 13
Path separator
- ‘\’ is path separator on Windows- ‘\’ is escape character on MySQL- Use ‘/’ instead: LOAD DATA INFILE ‘c:/tmp/table.dump’ ...
Wednesday, November 6, 13
CLI differences
- no pager- no readline- use ‘mysql’ package from cygwin instead
Wednesday, November 6, 13
Symlinks
- On Unix, you can symlink to MY[ID] files- On Windows, you can symlink to database directory - Does not work with innodb_file_per_table
Wednesday, November 6, 13
Config differences
- --standalone- --install / --install-manual / --remove- --slow-start-timeout - --socket / --enable-named-pipe - --shared-memory / --shared-memory-base-name- option separator ‘;’ (instead of ‘:’ on Unix) - i.e. for paths specified on tmpdir- innodb_flush_method : async_unbuffered
Wednesday, November 6, 13
No Percona binaries
- No date for this yet- Not impossible to build from source- No xtrabackup - mysqldump - MySQL Enterprise Backup

Feeling more at home

cygwin- Includes ‘mysql’ package (for unix client) - supports pager - supports readline - ~/.my.cnf will work- perl, bash (Percona Toolkit!)- vim, vmstat, etc...
Wednesday, November 6, 13
Measuring during troubleshooting
- vmstat from cygwin is decent- Resource Monitor- Performance Monitor

Percona Toolkit
Wednesday, November 6, 13
Rule of thumb
- Perl tools tend to work- Bash tools may or may not- Prefer Cygwin. ActivePerl may work too.

What I have used (successfully)
- pt-query-digest- pt-table-checksum- pt-mysql-summary- pt-stalk - band aid:edit check_disk_space() to always return 0 - pt-stalk --no-stalk --iterations 1

What was not on the previous slide, I have not used on Windows
