12.2 E-Business Suite Technology Stack Expected HTTP Server Processes (httpd) Do Not Start Based Upon Setting For Variable 'StartServers' In httpd.conf (Doc ID 2335092.1)

Last updated on DECEMBER 13, 2017

Applies to:

Oracle E-Business Suite Technology Stack - Version 12.2.4 and later
Information in this document applies to any platform.

Goal

E-Business Suite 12.2 Applications Technology Stack, HTTP Server for Applications Technology

 

 

 

 

Discuss the different settings for variable 'StartServers' in httpd.conf, and how the value relates to the number of HTTP server processes.

The variable 'StartServers' is a directive which sets the number of HTTP child server processes created at startup.

However when setting StartServers 5, users report the below observations at the OS level:
for example:
> ps -ef|grep httpd
r122 14981 14830 0 Sep20 ? 00:00:01 /home/EBS/r122/fs1/FMW_Home/webtier/ohs/bin/httpd.worker
r122 15065 14981 0 Sep20 ? 00:00:00 /home/EBS/r122/fs1/FMW_Home/webtier/ohs/bin/httpd.worker
r122 15301 14981 0 Sep20 ? 00:00:01 /home/EBS/r122/fs1/FMW_Home/webtier/ohs/bin/httpd.worker
r122 16950 14981 0 Sep20 ? 00:00:01 /home/EBS/r122/fs1/FMW_Home/webtier/ohs/bin/httpd.worker
r122 15865 9034 0 11:02 pts/4 00:00:00 grep httpd

In HTTP Server document <Note 2201817.1> the following guidelines are listed:

If StartServer is set to 2, you will have 1 parent httpd, 1 child httpd for OPMN and 2 child httpd processes to handle requests. For a total of 4 httpd processes.
If StartServer is set to 3, you will have 1 parent httpd, 1 child httpd for OPMN and 3 child httpd processes to handle requests. For a total of 5 httpd processes.
If StartServer is set to 4, you will have 1 parent httpd, 1 child httpd for OPMN and 4 child httpd processes to handle requests. For a total of 6 httpd processes.

The above leads E-Business users to request more information on why StartServers is set to 5, but only 4 processes are started to handle requests.
