Last updated on JUNE 29, 2023

Applies to:

Oracle HTTP Server - Version and later
Oracle Fusion Middleware - Version and later
Generic UNIX


OracleAS 10g HTTP Server on a Unix platform,  has been configured to listen on a port or ports with value < 1024

A startup of HTTP Server is failing.

The OPMN  HTTP_Server~1.log shows no error, only

<date time> Start process

The OHS error_log shows an error

.. [crit] (13)Permission denied: make_sock: could not bind to port ...

Analysis of the output from

suggests there are no other processes locking the port / socket required by HTTP Server.


Oracle HTTP Server was working fine, but problem elsewhere in the technology stack necessitated a restore from backup - LOHA -  using the OracleAS Backup Recovery Manager i.e the bkp_restore script. Following the restore, HTTP Server no longer starts.
