A few days a go me and my team start with project PSAK 50/55 for banking regulatory application. This application is about calculating fee amortization and calculation provision of debtor in bank. Our application is builted in .NET with oracle database.

I think all of you familiar with oracle. The version oracle that we used is Oracle 11g R2 and my team request me to explain about HOW TO SETUP ORACLE 11G R2 on windows 7. To install oracle we have 2 main step to do. First we must prepare all assets and number two the main step is installation. Let's start.

  1. Praparation Step 

  • Check the Bit of operating system
  • At least RAM 4GB (8GB or more is better, especially if you will also use Oracle’s development tools)
  • Disk space 4GB or more is better. The big size disk needs depend on where is place we put the data
  • Ensure sure the PATH of environment variable is shorter than 1,000 characters. If our path is more than 1.000 characters oracle cannot be installed properly and we must to replace the PATH and move old PATH with new PATH. 
  • Before we start we must have the Oracle installation. 
    • Source Oracle 11G Installation
    Source Oracle 11G R2 Installation
  • If we don't have the installer we can download from oracle site. Detail link as below : http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
