I’ve been struggling to get a TCPIP function working. The TCPIP documentation repeatedly says use the configuration in TCPIP.DATA. I did – and it made no difference.
What it should say is in the //SYSTCPD data set in your TCPIP procedure.
TCPIP started tasks such as the resolver, can query TCPIP and get the name of the dataset.
As I’ve said before, it is easy when you know the answer.
I also blogged this, so when I forget this in a few months time, and look for TCPIP.DATA , a search of the internet will find it.
