Overview
This RFC upgrade the Apache and Tomcat to the latest version, including:
- Upgrade Apache to 2.2.15 x86, to 2.2.14 on x64
- Upgrade TomCat to 6.0.24
Motivation
- The current release of Apache included in MGOS is 2.2.11 which has a know issue PR 47672 (https://issues.apache.org/bugzilla/show_bug.cgi?id=47672)
(Apache PR 47672: fix seg fault under load due to pool concurrency problem).
This Apache defect has been corrected in release 2.2.14.
- If a user attempts to configure Apache/Tomcat on Windows 64bit they will want to configure Tomcat as a service (this is very important for performance reasons).
The batch script to install the service appears to work, but the service fails to start under Windows Server 2008 64bit.
In order to correct this, we need to install 64 bit Tomcat binaries for the 64 bit version. The first build of Tomcat which includes 64 bit binaries is 6.0.24.
Proposed Solution
Upgrade the exsiting Apache to 2.2.15 on Linux and x86, to 2.2.14 on x64.
Upgrade the Tomcat to 6.0.24
Note:
- The latest Tomcat build is 6.0.26, however the 6.0.24 was fully tested with Autodesk MapGuide Enterprise 2011. So I'd like to move the Tomcat to 6.0.24 at this time.
- The 64 bit Apache is 2.2.14, which is from http://www.blackdot.be/?inc=apache/binaries. And it's not official Apache release.
