Applies to:

Oracle HTTP Server - Version and later
Information in this document applies to any platform.


Configured forms.conf in Forms 12c using the example note referenced in the deployment guide at the link below.


When including any user-defined aliasMatch with the prefix /forms/ in forms.conf, add the directive WLExcludePathOrMimeType. For example, in Linux, when defining the aliasMatch for /forms/usericons in forms.conf, the directive WLExcludePathOrMimeType is defined as following:

AliasMatch /forms/usericons/(..*) "/home/userx/myicons/$1"WLExcludePathOrMimeType /forms/usericons/

OHS fails to start with the following messages in the ohs1.log:

<INFO> <OHS-0> <AliasMatch takes two arguments, a regular expression and a filename>
<SEVERE> <OHS-0> <C:\Oracle\MW\ohs\bin\launch.exe C:\Oracle\MW\ohs\bin\httpd.exe -DOHS_MPM_WINNT -d C:/Oracle/MW/user_projects/domains/FormsReports/config/fmwconfig/components/OHS/instances/ohs1 -f C:\Oracle\MW\user_projects\domains\FormsReports\config\fmwconfig\components\OHS\instances\ohs1\httpd.conf: exit status = 1>
<INFO> <OHS-4005> <Check the instance log file for more information: C:\Oracle\MW\user_projects\domains\FormsReports\servers\ohs1\logs\ohs1.log>
<SEVERE> <OHS-0> <Failed to start the server ohs1>


 Added the following line to forms.conf:

 AliasMatch /forms/usericons/(..*) "/home/userx/myicons/$1"WLExcludePathOrMimeType /forms/usericons/
