In this post i try to show to  you way to make more easier Discoverer 10.1.2 installation on OEL5.5 x86-64 platform

Before start you must follow below document:

I am using setup which is avalibale under Business Intelligence part

There is no specific setup for linux x86-64. There is only available setup for linux x86.

If you run installation directly which you download from upper Discover setup,  it gives you below error:

disco@xxx Disk1]$ ./runInstaller

The Oracle Application Server 10g is a 32-bit application to be installed on either Linux x86 or Linux x86-64. There are 32-bit installation requirements on Linux x86-64 in order allow compatibility with the 32-bit Application Server product. Please see the Installation Guide for other general platform requirements.

For can run seup,  first set below line on your shell than try to start runInstaller again

disco@xxx Disk1]$ linux32 bash
disco@xxx Disk1]$ ./runInstaller

This command will you bring installation wizard but it will stuck on pre-request check steps.You will have “your OS is not certified” error durin installation wizard.

So the question is how we can pass this error. This issue already cover in first metalink note 564174.1.

Before installing Oracle Application Server 10g Release 2 (10.1.2.0.2) , you must apply Patch:6687768 in order to start the installer. If you do not apply this patch, pre-req check for the OS Version will fail when you invoke the runInstaller.

After apply path start installer as below:

disco@xxx Disk1]$ ./runInstaller -ignoreSysPrereqs

During installation you can hit some  error message while i faced with all issue on my installation. If you hit any error message during Discoverer 10.1.2 installation please check metalink note 564174.1 Known issue part
