Symptoms

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

https://docs.oracle.com/middleware/12213/formsandreports/deploy-forms/using-oracle-forms-services-http-listener-and-oracle-weblogic-server.htm#FSDEP233

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> <ORACLE_HOME\ohs\bin\launch.exe ORACLE_HOME\ohs\bin\httpd.exe -DOHS_MPM_WINNT -d ORACLE_HOME/user_projects/domains/FormsReports/config/fmwconfig/components/OHS/instances/ohs1 -f ORACLE_HOME\user_projects\domains\FormsReports\config\fmwconfig\components\OHS\instances\ohs1\httpd.conf: exit status = 1>

Changes

 Added the following line to forms.conf:

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