Backup large databases with mysqldump by splitting up the backup files

The primary responsibility of MySQL professionals is to establish and run proper backup and recovery plans. The most used method to backup a MySQL database is the mysqldump utility. This mysqldump utility creates a backup file for one or more MySQL databases that consists of DDL/DML statements needed to recreate the databases with their data. To [...]

How to get colored output from ‘ls’ on Solaris10
+0 Vote Up -3Vote Down

For all of those linux users out there that have moved over to, or tried out, Solaris10 or OpenSolaris because they heard the tales of how MySQL is faster on Solaris… or perhaps you wanted to learn how to use Sol10 for the great features of Zones or the ZFS filesystem? Regardless of why you’re on it you are probably wondering why Linux has colored output of filenames and directories but Solaris does not. The question of ‘why?’ isn’t important, but how to enable colors is. It’s very simple, and here’s how I fixed it. This is a result of digging through multiple semi-related links on Google.

Automating MySQL access with expect and bash scripting
+2 Vote Up -2Vote Down

If you have multiple database servers with strange names, or if you have to hop over multiple machines to connect to any mysql database server, then you know what a pain it can be to administer such a setup. Thanks to some scripting, you can automate such tasks as follows:

Create an expect script:
/path/to/sshmysql.exp

#!/usr/bin/expect -f
#script by darren cassar
#mysqlpreacher.com

set machine [lindex $argv 0]

set timeout -1

spawn ssh username@$machine
match_max 100000
expect -exact “assword: “
send — “password\r”
send — …

Introduction

StackOverflow is an amazing site for coding questions. It was created by Joel Spolsky of joelonsoftware.com, Jeff Atwood of codinghorror.com, and some other incredibly smart guys who truly care about user experience. I have been a total fan of SO since it went mainstream and it's now …

Replicating from MySQL to *
+3 Vote Up -0Vote Down

Recently I needed to replicate between MySQL and another database technology. You might say, why on earth would you want to do something like that, but believe me there are reasons and definitely not (to go away from MySQL to some other DB technology like Oracle or SQL server). Unsurprisingly there are quite a few different tools to do it from any platform towards MySQL but very few which do it the other way round, just to name a couple: Golden Gate and DSCallards.

Once again, I was unable to attend all of the sessions I wanted to at this year's User Converence, but I was happy to make it to Bob Burgess' talk on bash scripting with mysql. The slides and examples aren't up yet, but when they are (which may be as you read this, check the last link), they would probably also be a great tutorial.


So, I got bore^D^D^D^D inspired later that day to put some of the practices into use, and …

RESET SLAVE, bash edition
+0 Vote Up -0Vote Down

Nearly every job advertisement for MySQL DBA positions asks for ’shell scripting’, so I decided to investigate what it is. I remembered some performance training, where I was told how forking is bad, and one should attempt to use shell features as much as possible (like, avoid paths to something, what can be used by builtin (e.g. don’t use /usr/bin/[, just pure [ instead )

I tried to automate one MySQL DBA task (reinitializing slave after relay log corruption or after copying in cloned dataset from other server) using just bash - and it kind of worked. From now on I can put 'Shell scripting' proudly on my resume :-)

Next step - learn JCL …
