A quick consult with Dr Google shows lamentably few hits for

   "openvms sysconfig -r socket sb_max"

and the rest (though some which may be of interest).

I also notice an online manual

   "HP TCP/IP Services for OpenVMS Tuning and Troubleshooting"

available from various sites, e.g. (quoted to prevent wrapping)

which seems to be missing from the VSI collection

https://docs.vmssoftware.com/

Are the directives and recommendations still applicable to VSI TCP/IP 
Services 5 and 6?
