Installation of a version of IBM HTTP Server or Edge Caching Proxy supported by ihsdiag.

Installation Instructions

Install this ihsdiag package on the system with IBM HTTP Server or Edge Caching Proxy. You can also install ihsdiag on a personal workstation in order to view the enclosed documentation, or you can view the documentation from an IBM web site.

Invocation Instructions
The Java components of ihsdiag must be run under an IBM Java runtime of 1.4.2 or later. IBM HTTP Server 6.0.2 and later bundles a compatible Java runtime, so it is is suggested to invoke the java bundled by IBM HTTP Server instead of the java command found first in your path.

For information on using this diagnostic tools package for IBM HTTP Server issues (crashes, hangs, high CPU, startup failures), refer to this document and follow the links appropriate for your operating system and symptom:
