Purpose

This article provides a general problem solving approach to resolving the error:

Failure of server APACHE bridge

No backend server available for connection: timed out after 10 seconds or idempotent set to OFF.

Important to Note:

This troubleshooting support document features examples (including the images). These are "EXAMPLES ONLY". The fact, for example, that Oracle Forms is used as an example does not mean that processes and applications specific to the back end product (e.g. Oracle Forms) are responsible for the error. Troubleshooting efforts should focus on why there is a "disconnect" between the Oracle HTTP Server (OHS) mod_wl_ohs module and the given Oracle WebLogic Managed Server.

@Internal Only: If you resolve a Service Request or issue using a technique or problem solving path which is not described in this troubleshooting support document, please add a comment rather than create a new support document with a title containing the words 'Failure of server APACHE bridge'.
