Just send out resign letter, and will have a week of holiday in Japan, from 17/07 to 25/07 :-)

My Oracle 11gR1 gone crazy with 100% CPU loading when working with Debian sid. This page provide a functional solution:

Shutdown OEM, login as SYSMAN user and restart the provisioning daemon by executing the two packaged procedures

SYSMAN> execute MGMT_PAF_UTL.STOP_DAEMON

PL/SQL procedure successfully completed.

SYSMAN> execute MGMT_PAF_UTL.START_DAEMON

PL/SQL procedure successfully completed.

Start OEM again and the problem is gone.

WARNING: You must take this on your own responsibility!

So here is my detail procedures. For shutdown OEM (login as user oracle where Oracle 11gR1 installed in /u01/app/oracle/product/11.1.0/db_1/bin):

Login as SYSMAN:

Then execute the following PL/SQL commands:

Restart OEM:

Check the CPU loading and it should be fine now :-)

Debian only provide stable and testing installation CD/DVD so there is no way to install with sid directly. In order to use Debian sid, you will need to upgrade from existing installation. BTW, you may try once before but found that there was a lot of error message about package dependency, or not even able to complete the upgrade due to some tricky gap.

Here I will give you a simple guideline about how to upgrade in an elegant and stable style, from Debian stable or testing to sid.

This simple HOWTO will guide you about how to setup Apache2.2 + PHP5.2 + PDO_OCI from sketch. Compile all package from tarball can give you the maximum flexibility of functionality, e.g. you can enable both mysql/mysqli/pgsql/oci8/pdo_mysql/pdo_pgsql/pdo_oci within single installation.

Before start, I will assume you have Debian sid and Oracle 11gR1 installed correctly, which will not detail within this document.

This is a simple HOWTO, for installing Oracle Database 11g Release 1 on Debian sid.

But why we need this HOWTO? Since Oracle only officially support Red Hat Enterprise Linux, SUSE Enterprise Linux and other enterprise level Linux distribution; BTW, there shouldn't be any problem if you hope to use with other distribution, which just need some special configuration and install required dependent packages. On the other hand, some dependent packages are obsoleted in Debian etch, but only available in oldstable or sid, so install with sid should be better than etch + hybrid sid packages.

Before start you will need to prepare your Debian with:

• A complete Debian sid installation with X11.
• Static public IP address (or you may bind to localhost during installation).
• Functional hostname, e.g. hardcode it within /etc/hostname and /etc/hosts.

後人發，先人至。
軍無輜重則亡，無糧食則亡，無委積則亡。
兵以詐立，以利動，以分合為變者也。
其疾如風，其徐如林，侵掠如火，不動如山，難知如陰，動如雷霆。
避其銳氣，擊其惰歸。

以近待遠，以佚待勞，以飽待饑。

Long story short, you can seem KVM as replacement of VMware, XEN, VirtualBox, and so on (If you don't know what am I talking about, please give a look about what is Virtualization).

If you have play with similar solutions once before, the virtualization GUI shouldn't be new to you. The virtualization GUI usually provide an interface for client creation, managment and also operation, e.g. when you start a virtual client, the GUI will provide a window for it and display its screen message as like as real PC. So any similar solution for KVM? Yes, virt-manager (http://virt-manager.et.redhat.com/) is one of similar choice.

Besides previous 2 mini-HOWTO (KVM on Debian mini-HOWTO and libvirt + KVM on Debian mini-HOWTO), here I will guide you though how to employ virt-manager for more high level visualization handling.

Tagline (Site Subtitle) in MediaWiki is a bit similar as Drupal's site slogan, so how to configure it? Change the name of the wiki give a good example:

Tagline

The tagline can be edited either in the language files, or through the MediaWiki namespace. Using the latter method, the edit MediaWiki:Tagline and amend the existing text as required.

Note: Editing the MediaWiki namespace will only have an effect if $wgUseDatabaseMessages is set to true. This is the default.

So what's the meaning? Just edit the content of page MediaWiki:Tagline (e.g. http://example.com/wiki/MediaWiki:Tagline) and it will take effect to your tagline :-)

P.S. Some other useful resources:

• Category:MediaWiki Administrator's Handbook.
• MediaWiki Administrator's Handbook/Editing in the MediaWiki Namespace.

After a long long wait, start test and using it since Beta4, it's time to get it: Firefox3 is now release for public! Actually there is not much different from RC3, and just a build on 2008-05-29 (which also means RC3 is already stable enough so need not to have a new build):
About Mozilla Firefox

On the other hand, some useful plugin are now coming with Firefox3, too. E.g. Web Developer, Firebug, YSlow, ChatZilla and so on. This is the plugins that I am now using:

P.S. Since official site is now VERY busy, you may get my local copy from here, too.
