Issue/Introduction
When starting Oracle HTTP Server Web Agent, it fails.
The log file shows the following:
/{home_OHS}/user_projects/domains/base_domain/system_components/OHS/<server>.log

Environment
Web Agent 12.52SP1CR11 64 bit on Oracle Http Server 12c on RedHat 7.x 64 bit.
Resolution
Run the Web Agent configurator to integrate the Oracle HTTP Server with the Web Agent. Some instruction can help to configure manually after running the configurator (1).
The configurator on Linux has a file name called: ca-wa-config.bin
To configure properly the Web Agent on Oracle HTTP Server 12c, with the Web Agent configurator, find where the OHS server is installed and know the exact version of the Apache that the OHS Server runs:
In this sample, the Web Server is installed in
/{home_OHS}/user_projects/domains/base_domain/config/fmwconfig/components/OHS/instances/<server>
The Oracle HTTP Server (Apache) is 2.2.22 64 bit.
As <user> user (or the one given for the installation of OHS), those are the commands to know the exact Apache version:
# export LD_LIBRARY_PATH=/{home_OHS}/lib:/{home_OHS}/ohs/lib:${LD_LIBRARY_PATH}
# /{home_OHS}/ohs/bin/httpd.worker -V
Server version: Oracle-HTTP-Server/2.2.22 (Unix)
Server built: Jun 11 2025 13:18:04
Server Label: APACHE_12.1.2.0.0_LINUX.X64_130611.0942
Server's Module Magic Number: 20051115:30
Server loaded: APR 1.4.5, APR-Util 1.4.1
Compiled using: APR 1.4.5, APR-Util 1.4.1
Architecture: 64-bit
Server MPM: Worker
threaded: yes (fixed thread count)
forked: yes (variable process count)
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/worker"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS
-D DYNAMIC_MODULE_LIMIT=128
-D HTTPD_ROOT="$(APACHE2_HOME)"
-D SUEXEC_BIN="$(APACHE2_HOME)/bin/suexec"
-D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="conf/mime.types"
-D SERVER_CONFIG_FILE="conf/httpd.conf"
Then, run the Web Agent configurator that way to have the Oracle HTTP Server fully configured with the Web Agent.
This comes from the configuration of Web Agent 12.52SP1CR11 64 bit on RedHat 7.x.
In this sample, the host has been registered already with the Policy Server and the SmHost.conf is already created.
As root :
# cd /{home_web_agent}/install_config_info
