Forms or Reports 11g intermittently fails with an "Failure of Server APACHE Bridge" error in the browser or a FRM-92103 error in the form.

To resume normal working, the OHS component in the Forms / Reports technology stack has to be stopped and restarted.

The following errors are logged in <instance home>\diagnostics\logs\OHS\ohs1\ohs1.log file:

[2011-11-22T20:36:54.9189+00:00] [OHS] [ERROR:32] [OHS-9999] [mod_weblogic.c] [host_id: celvpint5309] [host_addr:] [pid: 3604] [tid: 1600] [user: SYSTEM] [VirtualHost: main] ap_proxy: trying GET /forms/frmservlet at backend host '; got exception 'NO_RESOURCES: [os error=0, line 1915 of ../nsapi/URL.cpp]: apr_socket_connect call failed hostname: error [730049]'

If mod_wl_ohs debug is enabled as per

<Note: 967889.1> How to View Oracle HTTP Server 11g MOD_WL_OHS Routing and Other Debug Information?

the following errors are logged in the mod_wl_ohs debug log:

The error is not specific to Forms / Reports 11.1.2 installations. It can be reproduced also on any Fusion Middleware Installation using OHS (Oracle HTTP Server) or . If unsure if your version is affected, run <ORACLE_HOME>\OPatch\opatch lsinventory -detail and check the "Patch of Oracle HTTP Server 2.0" version.


At configuration time, the WebLogic cluster option was chosen, and consequently the HTTP Server configuration file, containing the MOD_WL_OHS settings, has the directive WebLogicCluster

In the case of Forms / Reports this parameter is found in the forms.conf and reports_ohs.conf respectively.
