Oracle releases MySQL 5.5

Oracle after the acquisition of SUN , comes out strongly with the new release of open source Database MySQL. They have upgraded the version from 5.1 from 5.5. Oracle is targetting Mysql 5.5 for Web applications , then buddy what is Oracle targetted for???

They say that Oracle database is the leading enterprise database for high-end packaged applications: enterprise resource planning, customer relationship management, online transaction processing, large data warehouses and business intelligence applications.


MySQl is being widely used in opensource community and as it is part of LAMP, they believe it would be easier for LAMP administrators to handle MySQL when compared to ORacle.

When coming to Mysql 5.5 , whats new with this... 5.5 comes with better scalability and improved replication. Connection pooling has been improved drastically, now it can handle around 1000 connections at once. It also handles large datas with out slowing down the system.
The software can also offer additional performance gains when increasing the number of server cores beyond four, which previous versions were unable to do.

When looked at the performance level, Oracle showed that MySQL 5.5 showed a 360 percent improvement in reads and writes over version 5.1 running on Linux. On Windows Server machines, that performance gain jumped over 1,500 percent. "We get higher throughput in general with 5.5.

In terms of replication, the software now includes the ability to do semi-synchronous replications. Previous versions only offered asynchronous replications, meaning the backup copy of the database would not be updated as soon as new data was entered to the original.


These were the facts given by Oracle on its new release. Now lets wait and watch for more reviews on the usage of Mysql 5.5.

Hackers turn Google into vulnerability scanner

As i was just browsing on articles like online security i found an interesting thing which is called Goolog scan. "Goolag Scan" works as a Web auditing tool, and enables anyone and everyone to audit their own Web site through Google.May be this post is helpful for the system administrators of any organisation.
Here is more detailed information from Networkworld which says about Goolog scan

The hacking group Cult of the Dead Cow (CDC) has released a tool that turns Google into an automated vulnerability scanner, scouring Web sites for sensitive information such as passwords or server vulnerabilities.

CDC first achieved notoriety ten years ago with its backdoor Back Orifice, which demonstrated in a highly public way just how easy it was to take unauthorized control of a Windows PC.

The new tool, called Goolag Scan, is equally provocative, making it easy for unskilled users to track down vulnerabilities and sensitive information on specific Web sites or broad web domains.

This capability should serve as a wake-up call for system administrators to run the tool on their own sites before attackers get around to it, according to CDC.

The tool is a stand-alone Windows .Net application, licensed under the open source GNU General Public License, that provides about 1,500 customized searches under categories such as "vulnerable servers," "sensitive online shopping information" and "files containing juicy information."

The results are displayed as a list of links that can be opened directly in a browser. Example results include tell-tale error messages and Java applets for the remote control of surveillance cameras, according to CDC.

Goolag Scan is based on "Google hacking," the practice of exposing vulnerabilities via Google, which CDC says has been pioneered by a hacker going by the handle "Johnny I Hack Stuff."

Goolag Scan is, however, the first time such vulnerability searches have been built into a simple tool, according to CDC
