How to Enrol Website to Search Engines

Before registering a website to search engines, it helps if you know at a glance about how it works. Search engine is a database system designed to index internet addresses (URL, FTP, etc.). To carry out its duties, search engines have a special program that is usually called a spider, bot, or crawler. By the time you register a web address (URL), the search engine spiders will receive and analyze the URL. With certain algorithms, spider web will decide whether you submitted acceptable or not. If feasible, the spider will add the URL to their database systems. But if not, you are forced to be patient and repeat the registration within a certain period. The speed of each search engine crawler is different. Therefore, if you register the URL now, new possibilities can dilisting in 2 weeks to 2 months. This is because there are thousands of new URLs that register every day. Google.com and AllTheWeb.com are two search engines that have the largest capacity crawler today.

Lost Oracle SYS and SYSTEM password ?

If your administration is as good as anybodies, you are bound to loose the not-so-frequently used password for the SYS and SYSTEM users of oracle. Here are a few ways I found to re-set those passwords:

Method 1: SQLPLUS (Tested on AIX Oracle 9.2.0.1.0)
Log into the database server as a user belonging to ‘dba’ [unix ] or ‘ora_dba’ [windows ] group , typically ‘oracle’, or an administrator on your windos machine. You are able to log into Oracle as SYS user, and
