  • 1.  Using CKNSERVE on ADCD systems clone

    Posted 16 days ago

    Greetings all,
    Happy new year to you all.
    I am using CKNSERVE on a clone of an ADCD z/OS system. I have been getting an error as follows,
    CKN002I 12 BPX1GAI getaddrinfo for hostname failed RC 1 error in domain, reason 78AE 1004x

    In the SYSTCPT output I get the following shown,

    GetAddrInfo Searching Local Tables for IPv6 Address                  
    Global IpNodes Dataset  = USER.Z31D.TCPPARMS(ZPDTIPN1)               
    Default IpNodes Dataset = USER.Z31D.TCPPARMS(ZPDTIPN1)               
    Search order            = CommonSearch

     - Lookup for S0W3                                                   
    GetAddrInfo Searching Local Tables for IPv4 Address

     BPX1CLO:  RetVal = 0, RC = 0, Reason = 0x00000000                   
    GetAddrInfo Failed:  RetVal = -1, RC = 1, Reason = 0x78AE1004        
    GetAddrInfo Ended: 2026/01/11 16:11:40.900399                        

    When I look at USER.Z31D.TCPPARMS(ZPDTIPN1) I see I have specified,
      10.1.1.2     &SYSNAME..DAL-EBIS.IHOST.COM   &SYSNAME
      127.0.0.1       LOCALHOST                           

    When I replace this with the following the whole error goes away and CKNSERVE starts.
      10.1.1.2     S0W3..DAL-EBIS.IHOST.COM       S0W3    
      127.0.0.1       LOCALHOST                          

    The message I get are then as follows,

    GetAddrInfo Searching Local Tables for IPv6 Address         
    Global IpNodes Dataset  = USER.Z31D.TCPPARMS(ZPDTIPN1)      
    Default IpNodes Dataset = USER.Z31D.TCPPARMS(ZPDTIPN1)

    GetAddrInfo Ended: 2026/01/11 16:59:34.945959               
     

    Not sure why this is.
    Is it possible that CKNSERVE is reading the TCPPARMS library and not doing system variable substitution?

    Or I am missing something else?

    Hi Lennie

    With your system symbol in the /etc/hosts equivalent, USER.Z31D.TCPPARMS(ZPDTIPN1), does the TSO command PING S0W3 work?  I have looked, but could not find documentation to confirm the use of system symbols in /etc/hosts.  Documentation for other TCPPARMS members explicitly mentions use of system symbols, but (again) I could not find this for the HOSTS file.

    Also, when you edited the ZPDTIPN1 member to remove the symbol, you should have taken out the double dot too.

    Hi Lennie,

    FYI, 1004 indicates Domain Name not found.

    Regards,

    Paul.
