Uninstalling Oracle 10g Manually from Windows XP

Uninstalling Oracle 10g Manually from Windows XP
By Krishnamoorthy Sethuraman
List of additional steps to do for cleaning the system completely after uninstall using universal installer.
# Stop any Oracle services that have been left running.
Start->Settings->Control Panel->Services
Look for any services with names starting with ‘Oracle’ and stop them.
# Run regedit and delete the following keys (some may have slightly different names in your registry):
HKEY_CURRENT_USER\SOFTWARE\ORACLE
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet Services\EventLog\Application\Oracle.oracle
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet Services\OracleDBConsole
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet Services\Oracle10g_home
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet Services\OraclService
Note that the services control panel will still show the old services until you reboot.
# Delete the Oracle home directory
C:\Oracle
# Delete the Oracle Program Files directory:
C:\Program Files\Oracle
# Delete the Oracle Start Menu shortcuts directory:
C:\Documents and Settings\All Users\Start Menu\Programs\Oracle*
Where * indicates the name of your install. Look for and remove all Oracle directories from that location.
# Remove Oracle refereces from the path. To edit your path go to:
Start->Settings->Control Panel->System->Advanced->Environment Variables
Edit both of the environment variables user PATH and system PATH. Remove any Oracle references in them.
# Remove Oracle.DataAccess and any Polic.Oracle files from the GAC which is at:
C:\Windows\assembly\

Technical Terms in Oracle Apps explained through real time example


Story
The below example explains a few of the important terms and concepts used in the Oracle E-Business Suite. This would be a good starting point for the beginners to better understand the concepts behind Oracle Applications.
Say Harry is the owner of a wholesale fruit shop. He buys various fruits like apples, oranges, mangos and grapes etc from farmers directly and sells them to retail shop owners and also to the direct customers.
The farmers are referred to as VENDORS/SUPPLIERS in Oracle Applications. Harry
keeps track of all his vendors’ information like addresses,
bank account and the amount he owes to them for the fruits that he bought etc, in a book named PAYABLES.
Harry gets an order from a retail shop owner of Fruit Mart, for a shipment of 11 bags of apples, 25 bags of oranges and 32 kgs of grapes. In Oracle Apps, bags and kgs are referred to as UOM (unit of measure), Fruit Mart is calledCUSTOMER and the order is referred to as SALES ORDER. Harry maintains a book called
ORDER MANAGEMENT where he writes down all the details of the SALES ORDERS that he gets from his customers.
Say the fruits have been shipped to the customer Fruit Mart. Harry now sends him the details like cost of each bag/fruit, the total amount that the customer has to pay etc on a piece of paper which is called INVOICE / TRANSACTION. Once the INVOICE has been sent over, the customer then validates this against the actual quantity of fruits that he received and will process the payments accordingly. The invoice amount could be paid as a single amount or could be paid in installments. Harry’s customer, Fruit Mart pays him in installments (partial payments). So Harry has to make a note of the details like date received, amount received, amount remaining, amount received for what goods/shipments/invoice etc, when Harry receives the payments. This detail is called RECEIPT, which will be compared to the invoice by Harry to find how much Fruit Mart has paid to him and how much has to be paid yet. This information is maintained in a book named RECEIVABLES to keep track of all the customers, their addresses (to ship the items), what and how much he has shipped to his customers and the amount his customers owe him etc.
Harry’s fruit business has begun to improve and has attracted more and more customers. As a result, Harry decided to buy a cold storage unit where he could stock more fruits. In Apps, this cold storage unit is known as WAREHOUSE and all the fruits are referred to as INVENTORY. Due to increase in customers, Harry needs to hire more people to help him out in his business without any hiccups. These workers are called EMPLOYEES. At the end of every month, Harry pays the salary for all his employees through Checks. These checks are nothing but PAYROLL in Apps.
At the end of every month, Harry prepares a balance sheet in a book called GENERAL LEDGER to determine how much profit/loss he got and keeps track of the money going out and going in.
As the business grows, it becomes impossible to record everything on a paper. To make everybody’s life easier, we have very good tools in the market, which help the business men to keep track of everything. One such tool is Oracle E-Business Suite.
Oracle Applications is not a single application, but is a collection of integrated applications. Each application is referred to as a module and has it own functionality trying to serve a business purpose.
Few of the modules are Purchasing, Accounts Payables, Accounts Receivables, Inventory, Order Management, Human Resources, General Ledger, Fixed Assets etc.
Here is a high level business use of various modules:
Oracle Purchasing handles all the requisitions and purchase orders to the vendors.
Oracle Accounts Payables handles all the payments to the vendors.
Oracle Inventory
deals with the items you maintain in stock, warehouse etc.
Order Management helps you collect all the information that your customers order.
Oracle Receivables help you collect the money for the orders that are delivered to the customers.
Oracle Human Resources helps maintain the Employee information, helps run paychecks etc.
Oracle General Ledger receives information from all the different transaction modules or sub ledgers and summarizes them in order to help you create profit and loss statements, reports for paying Taxes etc. For Example: when you pay your employees that payment is reported back to General Ledgers as cost i.e money going out, when you purchase inventory items and the information is transferred to GL as money going out, and so is the case when you pay your vendors. Similarly when you receive items into your inventory, it is transferred to GL as money coming in, when your customer sends payment, it is transferred to GL as money coming in. So all the different transaction modules report to GL (General Ledger) as either “money going in” or “money going out”, the net result will tell you if you are making a profit or loss.
All the equipment, shops, warehouses, computers can be termed as ASSETS and they are managed by Oracle Fixed Assets.
There is a lot more in Oracle applications. This is the very basic explanation just to give an idea of the flow in ERP for the beginners.
