Real-time database replication (almost!)

admin — Sat, 05 Feb 2011 16:00:32 +0000

Been fortunate enough to join the first batch (i think!) of Oracle GoldenGate (OGG) in Malaysia.
OGG is the real-time database replication app which enhance Oracle Data Integrator (ODI).
I’ve seen the reason why database replication are important nowadays. One that I can relate is the emerging of cloud computing which need replication geographically.
Replication used by Disaster Recovery (DR) not usually replicate real-time.
OGG in my oppinion is not suite for DR eventho it can do the job well.
It suite well for real-time ETL in Data Warehousing and it can be geographically available in almost real-time.
The interesting idea that can be archive via OGG is something like, you can separate heterogeneous database for different function (like oracle for write and mysql for read) and make the data available realtime. This architecture help when lots of reading needed on the data.
Replication can be bi-direction, heterogeneous and multi master multi slave.

PHP5.3 : goto

admin — Mon, 19 Apr 2010 02:43:24 +0000

Pernah guna fungsi goto? last time aku guna mcm 4-5 tahun dlu. sebab dulu PHP memang takde.

/* function lock */
function lock()
{
    $file = fopen("file.txt","r+");
    retry:
    if(flock($file,LOCK_EX))
    {
        fwrite($file, "Success!");
        fclose($file);
        return 0;
    }
    else
        goto retry;
}

loop dalam function. nice?

CakePHP: Ternary condition

admin — Tue, 23 Mar 2010 00:00:25 +0000

Kalau selalu guna if and else, langkah seterusnya mesti tahu ternary condition. ade alternative lain nak guna dalam CakePHP, contoh:

 /* ife in cakePHP */
ife($condition, $true, $false)

jadi, kalau statement ternary tu cam ni:

/* ternary condition */
echo ($x)?'x = true':'x = false';

ble ubah jadi macma ni. mudah sket

/* replace ternary with ife in cakePHP */
echo ife($x, 'x = true', 'x = false');

urm.. dapat?

CakePHP: Kenapa layout masih tak tukar?

admin — Mon, 22 Mar 2010 06:28:05 +0000

Kalau malas asik nak declare layout di cakephp, aku akan guna code macam ni.

/* before Render */
function beforeRender()
{
parent::beforeRender();
 $this->layout = 'plugin';
....
}

lepas tu aku nak tukar stail layout, misalnya nak guna layout “ajax”. jadi aku declare macam ni..

/* children */
function children($id = null)
{
....
$this->layout = 'ajax';
}

tapi tak jadi!? kenape? perasan function beforeRender tu?

/* before filter */
function beforeFilter()
{
parent::beforeFilter();
….
$this->layout = ‘plugin’;
}

baru jadi! sebab beforeRender akan override balik variable sebelum render! sebab tu tak jadi.

Html helper, link untuk plugin

admin — Thu, 18 Mar 2010 04:37:15 +0000

Aku ada masalah nak buat link dari plugin page ke page biasa.

mula² jumpa cara macam ni..

$html->link(__(‘Home’, true), array(‘root’ => false, ‘plugin’ => false, ‘controller’ => ‘users’, ‘action’ => ‘home’), array(‘class’ => ‘menu’));

tapi still tak menjadi.. aku check cake version betul.. 1.2.5

jadi.. setelah mencari² cara macam mana nak reroute balik (kejalan yang benar) siap bukak source asal. rupa² nyer kena guna null. jadi seperti ni.

$html->link(__(‘Home’, true), array(‘root’ => false, ‘plugin’ => null, ‘controller’ => ‘users’, ‘action’ => ‘home’), array(‘class’ => ‘menu’));

kenapa false tak ok? pelik tapi benar
