The TCP/IP address space will hang in initialization if Unix System Services is (are?) not available.

I've heard 2 justifications for this: 1. Faster recovery if a TCP/IP stack crashes. Depending on the Tn3270 configuration, Tn3270 initialization can be lengthy. 2. In a multi-stack environment access to Tn3270 may still be available through another stack. (I did not hear this justification from IBM and have never worked in a multi-stack environment so I don't know if that explanation holds water.) In my opinion (which counts for nothing) this was not the right decission, but it was a purposeful one, not ust an accidental implementation. I think they could have made this behavior optional, but they forgot to ask me. :-) Pat O'Keefe ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
