IY94286: WHEN USING REMOTE DP'S THEY DO NOT RECONECT TO THE TARGET UA IF THE TARGET UA IS RESTARTED.

APAR status

• Closed as program error.

Error description

• When the UA that is hosting a remote DP is restarte the remote
  DP does not reconnect once the host UA is available again. The
  remote DP has to be cycled to get the connection back.
  
  Action Taken : Recreated steps as follows :-
  
  1. copied files required for remote DP to work to separate
  directory on
  laptop. (see dir output on Ecurep for filelist.).
  
  
  2. Placed testping.mdl in metafiles directory and updated
  KUMPCNFG file.
  
  3. Installed and started UA on hubtems (my main TEMS.)
  
  4. Checked that UA worked properly.
  
  5. Setup batch file to point to UA.
  
  6. Started remote DP using batch file.
  
  7. Monitored using TEP client to see when DP showed up.
  
  8. Stopped main UA.
  
  9. Waited 1 minute then restarted UA.
  
  
  10. Wait for UA to show available on TEP client.
  
  11. Wait 15 minutes to see if remote DP returns, it doesn't.
  
  12. Restart remote DP, returns immediately.
  
  
  batch file and MDL are both on Ecurep in recreate directory
  under normal
  PMR path.
  

Local fix

Problem summary

• UA supports use of running its data providers
  remotely, that is to run the data provider on host A when UA is
  running on host B.
  
  When UA is restarted and it is connecting to a remote DP the
  remote DP does not automatically reconnect to UA when UA is
  stopped and then restarted.  The remote DP has to be cycled to
  get the connection back.
  

Problem conclusion

• The key logic change is in kumptwdo.c where
  the DP-->DCH socket connection occurs.  Added a while (Retry)
  loop that's mainly intended to allow a standalone DP to keep
  trying the socket connection until the UA/DCH has been restarted
  and re-initialized.
