From the IP Configuration Reference Step 3: Configure VMCF and TNF The Pascal socket interface uses the IUCV/VMCF services for a limited set of inter-address space communication flows. As a result, if you are using any applications (provided by IBM or others) that use the Pascal socket API, you must ensure that the Virtual Machine Communication Facility (VMCF) and Termination Notification Facility (TNF) subsystems are active before the applications are started. TCP/IP provides the following applications and commands that use the Pascal socket interface: o SMTP and LPD servers o TSO HOMETEST, LPQ, LPR, LPRM, LPRSET, TELNET, and TESTSITE commands
Check the IEFSSNxx for statements starting the TNF and VMCF subsystems. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
