PQ04944: IF TCPIP IS NOT CONNECTED TO OPENEDITION WHEN THE OE FTPD SERVER IS STARTED, THE FPTD SERVER WILL TERMINATE IMMEDIATELY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If TCP/IP is not connected to OpenEdition when the OE ftpd
  server (ftp daemon) is started, ftpd will terminate
  immediately.  It will not retry the socket call.
   This situation prevents the use of the /etc/rc facility which
  automatically starts processes when OMVS is brought up.  The
  problem occurs when the ftpd process started with /etc/rc
  issues its socket call before TCP/IP has been able to connect
  to OpenEdition.

  OE ftpd needs to check the error on the daemon socket call, and
  if it's EAGAIN (resource temporarily not available) go to sleep
  and the try the socket call again after 60 seconds.
  

Problem conclusion

• The OE ftpd has been modified to check for EAGAIN errno on the
   socket() call and go into a sleep loop (every 60 seconds)
   retrying the socket() call until TCP/IP to OpenEdition
   connection is complete.
  
   The TCP/IP for OpenEdition MVS Version 3 Application Feature
   Guide (SC31-8069-00) should be changed as follows:
  
   If TCP/IP initialization is not complete before FTP is started,
   the FTP server will be unable to establish a socket and the
   following message will be sent to syslogd and written
   to the appropriate HFS file:
   EZYFT12E socket error: EDC5112 Resource temporarily unavailable
  
   The FTP server will continue to try every minute until TCP/IP
   initialization is complete, at which time FTP initialization
   can complete.  FTP will not recognize a stop command at this
   stage of its initialization, but you can issue a cancel
   command.
  
   The equivalent softcopy file will also be updated.
