PM13252: SMF119 SUBTYPE 70 RECORD SHOWS SMF119TI_STACK VALUE OF INET FOR FTP SERVER IN NON-CINET ENVIRONMENT RATHER THAN TCPIP STACK NAME

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A SMF119 subtype 70 record (FTP server transaction completion)
  shows a SMF119_TISTACK value of "INET" rather than the actual
  TCPIP stack name (TCPIPJOBNAME) when the FTP server is running
  in a single TCPIP stack environment that is not configured as
  CINET. The value "INET" in SMF119 records is not helpful for
  TCPIP stack identification reporting purposes especially when
  there are FTP servers running on multiple systems not configured
  as CINET and that have unique TCPIP stack names.
  
  A FTP server trace with options DEBUG FSC(2) and DUMP FSC
  will generate a "write_smf_record_119" trace record indicating
  the value of "INET" in the SMF119TI_STACK field at offset
  16(x'10') in the TCPIP Stack Identification record at offset
  28(x'1C').
  
  Because the "INET" value is actually returned from PFS in USS
  for a single stack environment that is not configured as CINET,
  coding a TCPIP stack name in the TYPE() parameter on the
  FILESYSTYPE statement in the SYS1.PARMLIB member BPXPARMXX
  will result in x'45A' (EAFNOSUPPORT) for unsupported address
  family. For example, using TYPE(TCPCS) for FILESYSTYPE will
  result in the following error message at TCPIP stack startup:
  
  EZZ4203I Z/OS UNIX - TCP/IP CONNECTION ERROR FOR TCPCS-BPX1SOC
                       00000003,FFFFFFFF,0000045A,112B0000
  
  Because PFS always return the value "INET" by design for
  single stack environments not configured as CINET, other
  methods have to be used by the FTP server to obtain the
  TCPIP stack name for the SMF119 subtype 70 records.

  ****************************************************************
  In INET environment, when writing SMF type 119 records for
  FTP server, we always get the "INET" but not the actual
  stack name in the stack name field in SMF records.
