I see many issues on OTN forum site which are related “File Not Found” errors during 11gR1 and 11gR2 installations.

While you are starting to make installation by running RunInstaller or Setup.exe you can hit “File Not Found” Errors for WFMLRSVCApp.ear, WFMGRApp.ear, WFALSNRSVCApp.ear files.

This is know issue.This error show us Unzip of downloaded install images was done incorrectly.

For 11GRx version on Unix ,you can follow:

$ mkdir setup
$ mv aix.ppc64_11gR1_database_disk1.zip setup
$ mv aix.ppc64_11gR1_database_disk2.zip setup
$ cd setup
$ unzip aix.ppc64_11gR1_database_disk1.zip
$ unzip aix.ppc64_11gR1_database_disk2.zip
$ cd database
$ ./runInstaller
For Windows ,you can follow:

– create a directory C:\tmp\Setup

– copy win32_11gR2_database_1of2.zip and win32_11gR2_database_2of2.zip under C:\tmp\Setup

– unzip win32_11gR2_database_1of2.zip and win32_11gR2_database_2of2.zip under C:\tmp\Setup
