Prior to MySQL 5.7, the CREATE USER command had a number of limitations:

• No way to set both authentication plugin and password
• No way to disable a user
• No way to define user resource limitations
• No way to set a non-default password expiration policy
• No way to require SSL/x509

All of these things could be done through other means, but typically involved other statements, such as GRANT commands. Starting with MySQL 5.7.6, these can all be done through a new and improved CREATE USER …

Compiling MySQL Workbench yourself is quite a common task for Linux users, even though the application is available precompiled for certain platforms ready from our download page and available in our yum and apt repositories. In this blog post we show you how to compile it on Windows.

Introduction

Doing a build on Windows is a totally different matter and most users never need to do that. It’s mostly intersting for those wanting own functionality or just being curious. But you should be an experienced Visual Studio user. It’s a complicated task and not a good start for a beginner. The key problem when building on Windows is that we cannot ship any 3rd party library we used. Instead you have to collect them all yourself. In order to ease that task we created the list below. Each library comes with a version number which usually specifies the minimum version to be used. Most of the time it’s not mandatory to use the exact …

UMASK and UMASK_DIR are amongst few MySQL Environment variables which defines directory and file creation modes (file permissions). In this post we will understand using UMASK & UMASK_DIR for changing the database directory and file permissions from it's default to what we need.

The post UMASK & UMASK_DIR – changing default MySQL file dir permissions first appeared on Change Is Inevitable.

A question I often hear when customers want to set up a production PXC cluster is: “How many nodes should we use?”

Three nodes is the most common deployment, but when are more nodes needed? They also ask: “Do we always need to use an even number of nodes?”

This is what we’ll clarify in this post.

This is all about quorum

I explained in a previous post that a quorum vote is held each time one node becomes unreachable. With this vote, the remaining nodes will estimate whether it is safe to keep on serving queries. If quorum is not reached, all remaining nodes will set themselves in a state where they cannot process any query (even reads).

To get the right size for you cluster, the only question you should answer is: how many nodes can simultaneously fail while leaving the …

The consumerization of IT and the integration of BYOD throughout the enterprise in recent years has made the customer king. And this means the end-user experience has become critical. The latest figures show that if your site doesn’t do a full page load in 3 seconds or less, then your customers will leave and abandon you and head over to your competitors site to spend their money there. Customers simply have no patience for slow, erratic, or downed websites. And this is why keeping your business-critical applications running optimally and efficiently is crucial for the success of your organization. Without this you might as well close up shop.

Application performance monitoring is the key to ensuring that the …
