After you unzip the OpenSSO Enterprise 8.0 Update 1 Patch 4 (or later) ZIP file, the Diagnostic Tool is in the ssoDiagnosticTools.zip file in the zip-root/opensso/tools directory, where zip-root is where you unzipped the Patch 3 ZIP file.
Create a directory for the Diagnostic Tool and its related files and then unzip the ssoDiagnosticTools.zip file in the new directory. The tool is available for these platforms:
Solaris and Linux systems: ssodtool.sh
Windows: ssodtool.bat
In this guide, diagnostic-tool-zip-root represents the directory where you unzipped the ssoDiagnosticTools.zip file.
