Mysql Cluster Manager 1.3.6 User Manual Abstract MySQL Cluster Manager 1.3.6 User Manual Abstract Deprecated release. MySQL Cluster Manager 1.3 has been superseded by later releases that add new features and incorporate fixes to bugs found in previous MySQL Cluster Manager releases; users of MySQL Cluster Manager 1.3.6 should upgrade as soon as possible. Thus, this document is archival in nature, and no longer actively maintained. Information about the most recent MySQL Cluster Manager release can be found at http://dev.mysql.com/ doc/mysql-cluster-manager/en/. This is the User Manual for the MySQL Cluster Manager, version 1.3.6. It documents the MySQL Cluster Manager Agent and MySQL Cluster Manager Client software applications which can be used to administer MySQL Cluster, a version of the MySQL Database System (referred to hereafter as “MySQL Server” or simply “MySQL”) that incorporates the NDB storage engine for high availability and data redundancy in a distributed computing environment. This Manual applies to MySQL Cluster Manager 1.3.6 and contains information that may not apply to older versions of the MySQL Cluster Manager software. For documentation covering previous MySQL Cluster Manager releases, see MySQL Documentation: MySQL Cluster, on the MySQL website. MySQL Cluster Manager features. This manual describes features that may not be included in every version of MySQL Cluster Manager, and such features may not be included in the version of MySQL Cluster Manager licensed to you. If you have any questions about the features included in your version of MySQL Cluster Manager, refer to your MySQL Cluster Manager license agreement or contact your Oracle sales representative. MySQL Cluster Manager, MySQL Server, and MySQL Cluster features. This manual contains certain basic information about MySQL Server and MySQL Cluster; however, it is not in any way intended as an exhaustive reference for either of these products. Current versions of MySQL Cluster compatible with MySQL Cluster Manager are based on versions 7.2, 7.3, and 7.4 of the NDB storage engine; these versions of MySQL Cluster are known as “MySQL Cluster NDB 7.2,” “MySQL Cluster NDB 7.3,” and “MySQL Cluster NDB 7.4,” respectively. MySQL Cluster functionality varies between MySQL Cluster releases; MySQL Cluster Manager cannot supply or emulate MySQL Cluster features that are not present in the version of the MySQL Cluster software in use. For complete information about MySQL Server and MySQL Cluster, please refer to the appropriate version of the MySQL Manual: For information about MySQL Cluster NDB 7.3 and 7.4, see MySQL NDB Cluster 7.3 and NDB Cluster 7.4. If you do not have the MySQL Server and MySQL Cluster documentation, you can obtain it free of charge from the MySQL Documentation Library, on the MySQL website.

  • Beyond Relational Databases
    EXPERT ANALYSIS BY MARCOS ALBE, SUPPORT ENGINEER, PERCONA Beyond Relational Databases: A Focus on Redis, MongoDB, and ClickHouse Many of us use and love relational databases… until we try and use them for purposes which aren’t their strong point. Queues, caches, catalogs, unstructured data, counters, and many other use cases, can be solved with relational databases, but are better served by alternative options. In this expert analysis, we examine the goals, pros and cons, and the good and bad use cases of the most popular alternatives on the market, and look into some modern open source implementations. Beyond Relational Databases Developers frequently choose the backend store for the applications they produce. Amidst dozens of options, buzzwords, industry preferences, and vendor offers, it’s not always easy to make the right choice… Even with a map! !# O# d# "# a# `# @R*7-# @94FA6)6 =F(*I-76#A4+)74/*2(:# ( JA$:+49>)# &-)6+16F-# (M#@E61>-#W6e6# &6EH#;)7-6<+# &6EH# J(7)(:X(78+# !"#$%&'( S-76I6)6#'4+)-:-7# A((E-N# ##@E61>-#;E678# ;)762(# .01.%2%+'.('.$%,3( @E61>-#;(F7# D((9F-#=F(*I## =(:c*-:)U@E61>-#W6e6# @F2+16F-# G*/(F-# @Q;# $%&## @R*7-## A6)6S(77-:)U@E61>-#@E-N# K4E-F4:-A%# A6)6E7(1# %49$:+49>)+# @E61>-#'*1-:-# @E61>-#;6<R6# L&H# A6)6#'68-# $%&#@:6F521+#M(7#@E61>-#;E678# .761F-#;)7-6<#LNEF(7-7# S-76I6)6#=F(*I# A6)6/7418+# @ !"#$%&'( ;H=JO# ;(\X67-#@D# M(7#J6I((E# .761F-#%49#A6)6#=F(*I# @ )*&+',"-.%/( S$%=.#;)7-6<%6+-# =F(*I-76# LF6+21+-671># ;G';)7-6<# LF6+21#[(*:I# @E61>-#;"# @E61>-#;)(7<# H618+E61-# *&'+,"#$%&'$#( .761F-#%49#A6)6#@EEF46:1-#

The typical configuration of any enterprise application is a 2 Node solution (Active-Standby mode or Active-Active Mode). The challenge lies in fitting the MySQL Clsuter Nodes in the 2 Nodes offering the application services and to make it work in that configuration with no single point of failure. 3.0 MYSQL CLUSTER The intent of this section is to briefly mention the important actors and their roles in the overall MySQL Cluster. For more information the reader can refer to the MYSQL reference documents from its official site (http://dev.mysql.com/doc/index.html). MySQL Cluster is a technology that enables clustering of in-memory databases in a “shared-nothing system”.

  • XAMPP Web Development Stack
    XAMPP Web Development Stack Overview @author R.L. Martinez, Ph.D. The steps below outline the processes for installing the XAMPP stack on a local machine. The XAMPP (pronounced Zamp) stack includes the following: Apache HTTP Server, MariaDB (essentially MySQL), Database Server, Perl, and the PHP Interpreter. The “X” in XAMPP is used to signify the cross-platform compatibility of the stack. The Apache HTTP Server and PHP are required to run phpMyAdmin which is a PHP application that is used for database administration tasks such as creating databases and tables, adding users, etc. Alternative to XAMPP If you have experience with MySQL Workbench, you may prefer to install MySQL Server and MySQL Workbench via the MySQL Installer. MySQL Workbench performs the same functions as phpMyAdmin. However, unlike phpMyAdmin which is a web-based application, MySQL Workbench is a locally installed application and therefore does not require an HTTP Server (e.g. Apache) to run. Installing XAMPP Many of the steps listed have several alternatives (such as changing MySQL passwords via a command line) and students are welcomed and encouraged to explore alternatives. 1. Download XAMPP from the URL below and place the installer (.exe) in the location where you want to install XAMPP. Placing the installer (.exe) in the same location as the intended installation is not required but preferred. http://www.apachefriends.org/download.html Page 1 of 17 XAMPP Web Development Stack 2. See the warning which recommends not installing to C:\Program Files (x86) which can be restricted by UAC (User Account Control). In the steps below XAMPP is installed to a USB flash drive for portability.

    THE VALUE OF OPEN SOURCE MICHAEL ”MONTY” WIDENIUS Entrepreneur, MariaDB Hacker, MariaDB CTO MariaDB Corporation AB 2019-09-25 Seoul 11 Reasons Open Source is Better than Closed Source ● Using open standards (no lock in into proprietary standards) ● Resource friendly; OSS software tend to work on old hardware ● Lower cost; Usually 1/10 of closed source software ● No cost for testing the full software ● Better documentation and more troubleshooting resources ● Better support, in many cases directly from the developers ● Better security, auditability (no trap doors and more eye balls) ● Better quality; Developed together with users ● Better customizability; You can also participate in development ● No vendor lock in; More than one vendor can give support ● When using open source, you take charge of your own future Note that using open source does not mean that you have to become a software producer! OPEN SOURCE, THE GOOD AND THE BAD ● Open source is a better way to develop software ● More developers ● More spread ● Better code (in many cases) ● Works good for projects that can freely used by a lot of companies in their production or products. ● It's very hard to create a profitable company developing an open source project. ● Not enough money to pay developers. ● Hard to get money and investors for most projects (except for infrastructure projects like libraries or daemon services). OPEN SOURCE IS NATURAL OR WHY OPEN SOURCE WORKS ● You use open source because it's less expensive (and re-usable) ● You solve your own problems and get free help and development efforts from others while doing it.

  • Mysql Cluster – Evaluation and Tests, OCTOBER 2, 2012 1 Mysql Cluster – Evaluation and Tests
    MySQL Cluster – Evaluation and Tests, OCTOBER 2, 2012 1 MySQL Cluster – Evaluation and Tests Michael Raith (B.Sc.), Master-Student F Abstract Websites or web applications, whether they represent shopping systems, on demand services or a social networks, have something in common: data must be stored somewhere and somehow. This job can be achieved by various solutions with very different performance characteristics, e.g. based on simple data files, databases or high performance RAM storage solutions. For today’s popular web applications it is important to handle database operations in a minimum amount of time, because they are struggling with a vast increase in visitors and user generated data. Therefore, a major requirement for modern database application is to handle huge data (also called “big data”) in a short amount of time and to provide high availability for that data. A very popular database application in the open source community is MySQL, which was originally developed by a swedisch company called MySQL AB and is now maintenanced by Oracle. MySQL is shipped in a bundle with the Apache web server and therefore has a large distribution. This database is easily installed, maintained and administrated. By default MySQL is shipped with the MyISAM storage engine, which has good performance on read requests, but a poor one on massive parallel write requests. With appropriate tuning of various database settings, special architecture setups (replication, partitioning, etc.) or other storage engines, MySQL can be turned into a fast database application. For example Wikipedia uses MySQL for their backend data storage. In the lecture “Ultra Large Scale Systems” and “System Engineering” teached by Walter Kriha at Media University Stuttgart, the question “Can a MySQL database application handle more then 3000 database requests per second?” came up some time.
