MySQL Console Pops Up Unexpectedly

MySQL database server provides an easy to implement and uses ANSI SQL syntax with wide implementation for many programming platforms. It is still open source licensed for the Community Edition as GPL (see details at mysql.com).

Current versions of MySQL Community Edition is available on Red Hat 6+, Centos 6+ and MS Window 10, for following versions;

• MySQL 5.6 GA on 5.2.2013
• MySQL 5.7 GA on 21.10.2015

Both versions are known to support current SQL standards, being SQL:2008.

Since using MySQL Community Edition version 5.6.21, something strange has been happening every midnight. A DOS like prompt pops up and very quickly does "something", which does NOT really allow me the time to read the messages and then it goes away (disappears). On one occasion I managed to capture that screen as the database it was trying to reach was not connected and here is how that screen looks like.

Apparently it was updating the MySQL catalogue, pretty harmless. The problem that I can see;

• Takes up additional processing which is not good when I am running emulators or CPU intensive work
• Distracts any on going work, such as when preparing documentation
• Disrupts desktop on-going recordings
• Disrupts benchmark operations

One could either disable the update process or assign it to another pre-defined time. On MS Windows 10, here are the steps to do either.

Step 1: Start MySQL Installer

Click the MS Windows Start and type; mysql installer
Click the Desktop App that appears. An upgrade my be required, proceed with the upgrade.

Step 2:  Edit Installer Options

In the installer option, click the Configure icon (Looks like a wrench).

1. To disable the automatic catalog update; Uncheck "Should MySQL Installer update its catalog periodically?"
2. To change the update time; Select a new time in "What time?" dropdown list.

Click Close.

Done.
