Goal
Oracle HTTP Server (OHS) 12c is the Web Server based on Apache HTTP Server 2.2 (12.1.x) and 2.4 (12.2.x). OHS includes modules developed specifically by Oracle.
Oracle HTTP Server 12c for UNIX Platforms (Linux,Solaris,etc...) supports and ships with different Multi-Processing Modules (MPMs) as following.
- Worker
- Prefork
- Event (from 12.2.x)
For Oracle HTTP Server 12c, the default MPM is "worker" for Unix. For Linux user, the default MPM is "event" from 12.2.x.
This document is intended to describe how to switch between the "prefork" MPM and the "worker" MPM in an Oracle HTTP Server 12c.
It is not recommended to config OHS instance with non-default MPM.
If you use Oracle HTTP Server 11g or Oracle HTTP Server 10g (based on Apache2.0) bundled with OracleAS 10g Companion CD
