In this example, the PROFILE DD statement is not specified:

//TCPIP  PROC PARMS='CTRACE(CTIEZB00)'
//*
//* z/OS Communications Server 
//* SMP/E Distribution Name: EZAEB01G

//TCPIP    EXEC PGM=EZBTCPIP,

2. jobname.nodename.TCPIP

   If jobname.nodename.TCPIP is found, the search stops here.

3. TCPIP.nodename.TCPIP

   If TCPIP.nodename.TCPIP is found, the search stops here.

4. jobname.PROFILE.TCPIP

   If jobname.PROFILE.TCPIP is found, the search stops here.

5. TCPIP.PROFILE.TCPIP
