How to install Oracle Database 10g release2 on widows XP

Specifications

A Pentium III or Pentium 4 based PC with at least 800 MHz processor, 256 MB of ram (512 is recommended) and at least 6 Gigabytes of free disk space.

If you only have 256 MB of RAM, make sure you have Windows manage at least 400 MB swap file (virtual memory).

At least 6 GB of free disk space:

Space to download or copy source ZIP files: 1.5 GB
Space to unpack source ZIP files: 1.5 GB

Space for Oracle data files (varies): 2.0 to 5.0 GB

Installation

After downloading Oracle10g  then  double-click on the setup.exe program to get the installation process started.

It is assumed that this is a fresh install so no other Oracle products should be installed at this time.

In this screen, the Source and Destination locations must be specified.

The Source path should reflect either your CD-ROM or the directory in which you unzipped the source files. Leave it as the default. In the example above, the source files were unzipped into

c:DOCUME~1HARILOCALS~1temprar$ex12.1593diskstageproduct.xml.

For the Destination, leave the Oracle Home named oraDb10g_home1 as the default. Choose a hard disk drive that has at least 6 gigabytes of free space. In the example here, we are using the E: drive.

Leave the Oracleproduct10.1.0db_1 path as it is (the default). If you have to select a different drive, only change the drive letter and not the directories.

Click on the Next button to select the installation type. This may take up to 2 minutes (dependingon the speed of your machine).
