How to backup your DB2

Xyiry — Mon, 15 Sep 2008 08:49:32 +0000

Hi today I’m going to share with you on how to backup your db2 database.

I’m assuming you guys are running db2 on Unix platform. So make sure you login as a DB2 Administrator.

For my case I logged in as db2inst1

Steps:

1) su db2inst1

2) db2 connect to databasename

3) mkdir /usr/db2backup

4) db2 backup db databasename to /usr/db2backup

So that’s all for db2 backup.

Configure Cake PHP on Zend Core For Oracle

Xyiry — Sun, 20 Apr 2008 08:51:27 +0000

If you guys are running XAMPP as your apache then its a piece of cake for you to configure cakePHP for the first time.

just open your httpd.conf and look for the following line and uncomment it
LoadModule rewrite_module modules/mod_rewrite.so

But if you guys are running Zend Core as your apache then you will need a little bit more effort to configure your cakePHP for the first time.

Look for these lines in your httpd.conf

1. LoadModule rewrite_module modules/mod_rewrite.so
(Uncomment It)
2.
Options FollowSymLinks
AllowOverride None

(Change to this)

Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all

3. AllowOverride None (Change to this) AllowOverride All

4. Restart you apache service and refresh your browser.

That’s it, Good Luck
