In this blog series, I will share my experiences as I migrate commercial databases (i.e., Microsoft SQL or Oracle) to open source (MySQL). More specifically, we will look at how you can migrate from MS SQL Server to MySQL.

For this first blog post I’ve chosen Jira database as an example, and used three different tools to migrate Jira database in Microsoft SQL Server to MySQL:

1. MySQL Workbench (opensource)
2. Amazon DMS (cloud tool)
3. Ispirer MnMTK 2015 (commercial tool)

When I started my research, I was under the impression that Jira database would be easy to migrate (no stored procedures, no triggers, etc.). It turned out that there were some problems that I was able to fix.

One of the reasons I chose Jira as opposed to some standard MS SQL database (such as AdventureWorks2014) is that it is a non-standard …

Ahoi,There will be the IT-Tage 2016 conference. Where I'm going to give two talks. One will be about Docker being more then a technical revolution. The other one is about Best Practices for Docker+MySQL/MariaDB \o/
As always: fun first! Erkan

Welcome to this week’s Planets9s, covering all the latest resources and technologies we create around automation and management of open source database infrastructures.

In this blog, I will provide answers to the Q & A for the Troubleshooting configuration issues webinar.

First, I want to thank you for attending the June, 9 webinar. The recording and slides for the webinar are available here. Below is the list of your questions that I wasn’t able to answer during the webinar, with responses:

Q: What are the predefined roles installed per default?

A: MySQL does not support roles by default. But, if you need roles you can either use …

On behalf of the Percona Live Conference Committee, I am excited to announce the sneak peek schedule for the Percona Live Europe Amsterdam 2016 talks!

Percona Live Europe will feature a variety of formal tracks and sessions related to MySQL, MongoDB and ODBMS from members of the open source community. With many slots to fill, there will be no shortage of great content this year. Though we won’t finalize the entire conference schedule until mid-July, this preview list of talks is sure to whet your appetite! So without further ado, here is the SNEAK PEEK SCHEDULE!

To operate MongoDB efficiently, you need to have insight into database performance. And with that in mind, we’ll dive into monitoring in this second webinar in the ‘Become a MongoDB DBA’ series.

MongoDB offers many metrics through various status overviews and commands, but which ones really matter to you? How do you trend and alert on them? What is the meaning behind the metrics?

We’ll discuss the most important ones and describe them in ordinary plain MySQL DBA language. And we’ll have a look at the open source tools available for MongoDB monitoring and trending.

Finally, we’ll show you how to leverage ClusterControl’s MongoDB metrics, dashboards, custom alerting and other features to track and optimize the performance of your system.

Introduction

XA stands for “eXtended Architecture”, and is a standard created by The Open Group for distributed transaction processing. While MySQL 5.0 was the first version to support XA, MySQL 5.7 has removed major limitations,  fixed a number of bugs, and increased overall test-case coverage.…

In this post, we’ll discuss Docker automatic MySQL slave propagation for help with scaling.

In my previous posts on the Docker environment, I covered Percona XtraDB Cluster. Percona XtraDB Cluster can automatically scale by conveniently adding new nodes using the highly automated State Snapshot Transfer. State Snapshot Transfer allows a new node to copy data from an existing node (I still want to see how this is possible with MySQL Group Replication).

This is not the case with regular MySQL Replication. With MySQL Replication, the slave setup still requires manual steps (well, unless you’ve already scripted it for your environment). At least these are “simple” steps (ha!). Percona XtraBackup can setup replication with less work (see this link for details:  …

This post is a continuance of my Docker series, and examines Running Percona XtraDB Cluster nodes with Linux Network namespaces on the same host.

In this blog I want to look into a lower-level building block: Linux Network Namespace.

The same as with cgroups, Docker uses Linux Network Namespace for resource isolation. I was looking into cgroup a year ago, and now I want to understand more about Network Namespace.

The goal is to both understand a bit more about Docker internals, and to see how we can provide network isolation for different processes within the same host. You might need to isolate process when running several MySQL or MongoDB instances on the same …
