Cant Set Host

Hi every1,


i have a alpha ds15 server loaded with vms7.3-2 and TCPIP V5.4-15.  when i do a $ucx sh host, i get the following.


$ ucx sho host
%TCPIP-E-HOSTERROR, cannot process host request
-TCPIP-W-NORECORD, information not found
-RMS-E-EOF, end of file detected


Please advise how can i fix this. I want to add the localhost to it.  Thanks

   As usual, showing actual commands with their actual output can be
more helpful than vague descriptions or interpretations.

      tcpip show version

   That may depend on how you got into this state.

   The default hosts data base should already contain an entry for
"localhost".  Did you try to edit the hosts database file?  (Not a good

      dire /full TCPIP$HOST

Does it say "File organization:  Indexed, Prolog: 3, Using 2 keys

   If you've damaged "SYS$COMMON:[SYSEXE]TCPIP$HOST.DAT;1", then you
might try deleting it, and using:
      tcpip create host
to make a proper one.  Of course, I have no idea what will then be
missing from your new hosts data base, but if you stick with "set host"
and/or "convert /vms host" commands, then you might be able to
reconstruct something useful.

Thanks Mr Steve.



I manage to get it fixed with you help. Thanks once again.




Re: Cant Set Host

I did a


dire /full TCPIP$HOST


to get the location of the file and then set default to that file. I opened the SYS$COMMON:[SYSEXE]TCPIP$HOST.DAT;1 and checked what was the file organisation. it was not Indexed, Prolog: 3, Using 2 keys.


For backup reason reason i copied the tcpip$host.dat file and then deleted the file.


Later i created a new TCPIP$HOST file using TCPIP CREATE HOST. it worked fine after that.
