History of MySQL


| 9 02/04/10

In the beginning

Founded by

David Axmark

Allan Larsson

Michael “Monty” Widenius

Named after Monty’s daughter “My” (Pronounced mee)


Ownership

Remember MySQL is Open Source: Anyone can compile the source code and use the binaries as long as they follow the rules of the license.

Jan 2008:Sun purchased MySQL for $1B

Oracle purchased sun about year later for $7.4B

FUD ensues…

Today, MySQL continues to live on


What about IBM i?

Two years ago Oracle dropped support for MySQL on Power and discontinued compiling the binaries.

Old binaries still available on Oracle archive site

IBM began looking for a new suitor

Zend stepped up and took over the binary distribution for MySQL for IBM i and the new product is called Zend DBi

Same wonderful MySQL, just compiled for POWER IBM i

Available for no charge at www.zend.com/products/dbi

http://www.zend.com/products/dbi


Installation, Zend DBi


First, remove old version??? • If you have no real data…

• Stop ZMYSQL Subsystem

• Delete ZMYSQL library

• RMVLNK ‘/usr/local/mysql*’

• Knowledge base article 305 (Dated but still useful!)

• http://kb.zend.com/index.php?View=entry&EntryID=305

http://kb.zend.com/index.php?View=entry&EntryID=305


Zend DBi Installation process

• Documented at Zend.com

• Option to install or update within point release

• Can update 5.1.n to 5.1.current (Zend Server)

• Cannot update 5.0.n (Zend Core)

• Download .zip from Zend.com, contains SAVF & README

• Follow readme.txt in SAVF, pretty straight forward

• Required LP’s are typically installed before Zend Server

• A word about QSECOFR…

| 14 02/04/10


Update anyone? • Here we have 5.1.50 (install with ZS 5.1)

• Let’s go up to 5.1.59

| 15 02/04/10


Start the installation process • Have ROOT password before updating

• Just stop ZMYSQL

• GO ZMYSQL/ZCMYSQL

• Option 5 then Option 2 then exit MySQL menu

| 16 02/04/10


Get SAVF to IBM i • FTP and check it…(DSPSAVF)

| 17 02/04/10


Start the update process • Steps to fire up process

• RSTLIB SAVLIB(ZMYSQL)

• CHGCURLIB ZMYSQL

• CALL ZMYSQLUPG1…update begins…

| 18 02/04/10


Set update options • Have ROOT password before you get here

• Will run MySQL script to update!

• Without ROOT process will fail, QSECOFR doesn’t work here!

| 19 02/04/10


Woohoo!

| 20 02/04/10


New subsystem and daemon • ZENDDBI

• ZENDDBID

| 21 02/04/10


MySQL Command Line


MySQL Monitor • MySQL has no native GUI interface (sound familiar?)

• Command line accessible from QSHELL, QP2TERM, etc.

• This is the brute force method for accessing.

• Will show you access, but not a big fan.

• Fully documented at mysql website

• Many books on the subject

| 23 02/04/10


Starting MySQL Monitor • I typically use CALL QP2TERM, can use QSH, etc.

• The mysql> is the prompter for the monitor

• Mysql –u root (First time, please set password!)

• Mysql –u root –p mikey

| 24 02/04/10


List all the databases • Show databases; • List all databases in MySQL

• Database is like a library

• Usually sorted by application

| 25 02/04/10


Set database • Use <DBNAME>

• Selects the database you will use for processing

• Database is like a library, where you store tables, etc.

• Typically on database per application

| 26 02/04/10


List tables

| 27 02/04/10


Display the user table

| 28 02/04/10

• Use SQL,

• select host, user, password from user;

• Use quit to end the session in the MySQL Monitor and F3 to close shell.


Are there any GUI’s?


Many GUI solutions

Adminer

Single PHP script

Lightweight, powerful and easy to use

phpMyAdmin

Widely used by community

Installed with Zend Server


Adminer


phpMyAdmin • Open Source PHP Project

• Provides nearly every access to MySQL you might need

• Installed automatically with Zend Server.

• Launch from Zend Server MonitorDashboard tab

| 32 02/04/10


phpMyAdmin – Set ROOT password • Login with “root” profile

• Create your profile

• Test your profile

• Change root password IMMEDIATELY (if not sooner)

• This is a similar process as you might use for new LPARs

| 33 02/04/10


Tour the dashboard..then on to privileges

| 34 02/04/10


Privileges • Click Add new user

• Fill out details, click GO

| 35 02/04/10


Look at databases & tables • Left hand navigation

• Right hand workspace

• FULL CRUD capabilities

• Think DFU for MySQL!

| 36 02/04/10


IBM DB2 Storage Engine


Why use MySQL to store data in DB2?

Many PHP applications in the open source arena

These application “talk” to MySQL by design

Modifying to access DB2 can be cumbersome & then updates?

Zend DBi includes IBM DB2 Storage Engine

Two instructions and you are there!


Architecture


How to install

From the MySQL Monitor in QSH or QP2TERM

Now go to phpMyAdmin and select the engine


IBM DB2 Storage Engine:phpMyAdmin

Create Table, set number of fields

Select storage engine


phpMyAdmin gives you the SQL!


Add records to table


What happened on the i?

Library test was created

Table was created

Records populated


Records, please?

STRSQL

Select * from test/exampleDB2
