Replication from Oracle to MariaDB the simple way - Part 2

The theme for this series of posts is, and indicated in the previous post, "Try and try, again", and there will be more of this now when I start to make this work by playing with Oracle, with PL/SQL and with the restrictions of Oracle Express (which is the version I have available).

So, what we have right now is a way of "sending" SQL statements from Oracle to MariaDB, the question is when and how to send them from Oracle. The idea for this was then to use triggers on the Oracle tables to send the data to MariaDB, like this, assuming we are trying to replicate the orders table from Oracle to MariaDB:
In Oracle, and assuming that the extproc I have that created to send UDP …

Replication from Oracle to MariaDB the simple way - Part 1

Yes, there is a simple way to do this. Although it might not be so simple unless you know how to do it, so let me show you how this can be done. It's actually pretty cool. But I'll do this over a number of blog posts, and this is just an introductory blog, covering some of the core concepts and components.

But getting this to work wasn't easy, I had to try several things before I got it right, and it's not really obvious how you make it work at first, so this is a story along the lines of "If at first you don't succeed mr Kidd" "Try and try again, mr Wint" from my favorite villains in the Bond movie "Diamonds are forever":
So, I had an idea of how to achieve replication from Oracle to MySQL and I had an idea on how to implement it, and it was rather simple, so why not try it.

So, part 1 then. Oracle has the ability to let you add a UDF (User Defined Procedure) just like MariaDB (and MySQL), …

Importing related MySQL tables into an Excel Data Model using MySQL for Excel

In this blog post we are going to talk about one of the features included since MySQL for Excel 1.3.0. 

Importing MySQL data into Excel is a common and important operation in MySQL for Excel. There may be times when you need to analyze the data stored in several MySQL tables or views, (possibly in an ExcelPivotTable which will be the subject of a future blog post), and to do it you need to dump the data into Excel as the first step. Starting with MySQL for Excel 1.3.0 we introduced a feature that allows you to import the data from multiple MySQL tables or views in a single operation.

Remember you can install the latest GA or maintenance version using the MySQL Installer or optionally you can download directly any GA or non-GA version from the  …

Accessing Fabric HA Groups from Java

It's been almost a year now since the initial release of MySQL Fabric. It is maturing and reached a GA state earlier this year as part of MySQL Utilities 1.4. Developers and architects are evaluating it for their applications, learning the capabilities of the system, and providing feedback for future features and usability enhancements. Connector/J has supported Fabric from the very beginning and continues to support the latest features. This blog post is an introductory level guide to using Fabric for high-availability from Java applications. Sharding features and Java APIs will be covered in a later post. The commands shown and feature descriptions are current for Fabric 1.5.1. In addition, Connector/J 5.1.32 and later support only Fabric 1.5 due to communication protocol differences from Fabric 1.4.

High-availability is a core concept in Fabric and is implemented by HA groups. An HA group is a set of servers configured with MySQL …

MEB copies binary logs and relay logs to support PITR and cloning of master/slave

With MySQL Enterprise Backup(MEB) 3.9.0 we had introduced full instance backup feature for cloning the MySQL server. Now with MEB 3.11.0 we have enhanced the feature by copying all the master-slave setup files like MySQL server binary logs(will be referred as 'binlogs'), binary log index files, relay logs of slave, relay log index files, master info of slave, slave info files. As part of full instance backup, copying of binlog files is default behavior MEB-3.11.0 onwards. DBA should be aware of the fact that current full instance backup is bigger than the backups with old MEB's.

As every event on MySQL production database goes as a entry to binlog files in particular format, binlog files could be huge. Backing of huge binlog and/or relaylog files should not impact the performance of MySQL server. Hence, all the binlog files, …
