The folks at OTN have been very busy — among many others (both virtual and in RL), there are two upcoming developer/sysadmin days about MySQL and Solaris. Both will take place in California next month:

• On Tuesday, May 03, 2011, 8:00am to 4:00 pm, there will be the OTN Developer Day for MySQL in the Oracle Santa Clara Agnews Campus Auditorium. It will cover application development with MySQL, performance tuning tips and managing MySQL environments.
• On Tuesday, May 17, 2011, 8:00 am to 4:00 pm, the OTN's first …

Cannot give you all details yet and it's too early to say what the max performance we'll finally obtain, but currently we out-passed 100.000.000 (!) Read+Write transactions/sec on the latest MySQL 5.5 simply integrated on the Exadata X2-8 (full rack) instead of Oracle database!!! :-))

The result is so incredible.. - but we spent several days now to validate that workload is perfectly matching customer's requirement and really reproducing their production environment. The problem came from the performance issue they observed month to month and came in our Benchmark Center to test a new HW platform (and we're in competition here with HP and IBM, but they have already finished their testing and without a positive result (no comments.. ;-))).. Finally, no one of any tested platforms was able to keep the load expected for the end of the year.. And of course we think about Exadata :-)) but the problem that the customer's application is …

Three ways to recover a root user password:

The order of solutions here under gets more creative on the way down :)

1. obviously, before starting messing around check my.cnf or scripts for passwords entries, then try home directories for password files
2. secondly – can you restart mysql? if yes, restart with –skip-grant-tables, log into mysql, change your password and restart without –skip-grant-tables
3. third option – (on linux / unix ONLY)
If you haven’t found the password anywhere and can’t afford to restart your mysql.

cd data/mysql
cp -rp user.MYD bck_user.MYD_`date +%Y%m%d`
cp -rp user.MYD /tmp/user.MYD
vi /tmp/user.MYD #(edit the hashed passwords next to root*)
cp -rp /tmp/user.MYD user.MYD
sudo kill -HUP `pidof mysqld`

Note that the latter method of recovering a root password CAN be easily used maliciously leaving no trace! The only way to avoid such an attack is to make the …

So far the benchmarking script supports Linux, FreeBSD, and OSX. I’m installing virtual machines today to get ready for development on the next OS that the community wants to have supported. Vote today for your choice. Development will begin Friday 2010-09-03.

Last week's "announcement" of the death of OpenSolaris has steered a lot of questions my way about where people should go, and/or where OmniTI will go, now that OpenSolaris future looks non-existent. As one of the more open users of Solaris related technology, and running some beefy loads on top of it, it makes sense that people would be curious as to what we might be doing next. I would start with saying that as a company, we don't have an official policy on this yet, and probably won't. We evaluate each situation on a customer by customer basis, so what follows here is more my personal …

Here’s a simple answer to a simple question. “How do I run a backup of MySQL to another machine without writing to the local server’s filesystem?” – this is especially useful if you are running out of space on the local server and cannot write a temporary file to the filesystem during backups.

Method one – this writes a remote file.
mysqldump [options] [db_name|--all-databases]| gzip -c | ssh user@host.com "cat > /path/to/new/file.sql.gz"

Method two – this writes directly into a remote mysql server
mysqldump [options] [db_name|--all-databases]| mysql --host=[remote host] –user=root –password=[pass] [db_name]
