Oracle Enhances MySQL Manageability on Windows
Employee_Team +2 Vote Up -0Vote Down

Windows is a major development and deployment platform for MySQL. A few months ago, we held our first MySQL Online Forum, dedicated to MySQL on Windows. We outlined then why MySQL was a great fit for the Windows environment, and what were the upcoming milestones to make MySQL even better on the Microsoft platform.

LRU follow up
+0 Vote Up -0Vote Down

Due to one of the machines being configured a little bit too close to the edge we had to restart it to downsize its innodb_buffer_pool_size a little bit. We tested the innodb_lru_dump_restore directive with this machine. Results were very promising: it wrote the dump every 5 minutes (we set the variable to 300 seconds) and after MySQL had restarted it reloaded the dump.

Handling Human Errors
+0 Vote Up -0Vote Down

Interesting question on human mistakes was posted on the DBA Managers Forum discussions today.

As human beings, we are sometimes make mistakes. How do you make sure that your employees won’t make mistakes and cause downtime/data loss/etc on your critical production systems?

I don’t think we can avoid this technically, probably working procedures is the solution.
I’d like to hear your thoughts.

I typed my thoughts and as I was finishing, I thought that it makes sense to post it on the blog too so here we go…
