DSA editionsThis information describes the different editions of DSA that are available.Two editions of Dynamic System Analysis are available:v DSA PortableDSA Portable Edition runs within the operating system; you do not have torestart the server to run it. It is packaged as a self-extracting file that youdownload from the web. When you run the file, it self-extracts to a temporaryfolder and performs comprehensive collection of hardware and operating-systeminformation. After it runs, it automatically deletes the temporary files and folderand leaves the results of the data collection and diagnostics on the server.If you are able to start the server, use DSA Portable.v DSA PrebootDSA Preboot runs outside of the operating system; you must restart the server torun it.
