6.3 Limit the number of HTTPD processes

To avoid spawning too many HTTPD processes (which is memory consuming) set the following directive in the Oracle HTTP Listener configuration file (httpd.conf):

KeepAlive Off

If you must use KeepAlive On, for example, for another application, make sure that KeepAliveTimeout is set to a low number for example, 15 seconds, which is the default.
