Last updated on AUGUST 20, 2019

Applies to:

Oracle HTTP Server - Version to [Release AS10gR2]
Oracle Containers for J2EE - Version to [Release AS10gR2]
Information in this document applies to any platform.



Oracle Application Server IDM (Identity Management) 10.1.4 installed running SSO and OID services, and Oracle Application Server 10.1.2 HTTP Server (Apache 1.3) on another node.
Attempting to replicate a deployment described in the Oracle Identity Management 10.1.4 Enterprise Deployment Guide whereby an HTTP server is configured to act as an SSO front-end and directs single sign on requests to the SSO/OID servers using the AJP13 protocol.

The configuration works fine over AJP,  but if it is configured over SSL ( i.e. AJPS ), the HTTP Server does not start.

The following error can be seen in the HTTP Server OPMN log file HTTP_Server~1:

<date time> Start process
ORACLE_HOME/Apache/Apache/bin/apachectl start: execing httpd
[<date time>] [error] MOD_OC4J_0366: Failed to load iaspt library file "" and the error message is " cannot open shared object file: No such file or directory".
