Hi Romeo,

You can actually find quite a good deal of information on many of the more common profile parameters within the application itself. For instance, if you call up transaction RZ11 and put in the parameter you're interested in (e.g., "em/address_space_MB"), then click on Display docu, you'll get inline help on what the parameter is for and how it's used, etc.

Another good place to start inside the application, with memory and performance-related parameters, is ST02. Simply double-click on a buffer or memory area of interest, then click Current Parameters, and you will get a list of the parameters related to that buffer or memory area. Selecting the parameter and clicking Change Profile parameter will then bring up RZ11 with that parameter pre-populated.

Another method of parameter discovery is with the report RSPARAM. This will list all parameters in your system, and again double-clicking them will bring up details and a link to online documentation.

Finally, not to toot my own horn -- well, ok, perhaps just a little bit -- I wrote a blog some time back about buffer tuning that you might find a useful place to start: https://blogs.sap.com/2015/09/08/auto-tune-your-buffers-with-kernel-742/.

Cheers,
Matt
