    Is there a tool or a way to compare the same HL7 variants between two sites?

      What platform?  If they are on the same server, you may be able to use something like ‘dircmp’.

      On AIX:

      dircmp

      Purpose

            Compares two directories and the contents of their common files.

      Michael,

      If the variant actually has differences from the standard, you could (assuming UNIX) do a diff or sdiff on the files that make up the variants.

      Since there could be multiple files depending on how the variant differed from the standard, it would mean multiple diffs.

      You could also use Ultra-Edit if you have it to point to the files via FTP and use Ultra-Edit’s difference checker.

      If there are no differences from the standard (meaning there are no segment, or messages, or fields entries in the respective directories) then they are, by definition equal (assuming same HL/7 version)

      I’m on AIX.

      I was hoping for a Healthvision tool.

      Looks like I have to do it the hard way. I’ll look at the dircmp.

      Thanks in advance guys

      One thing to look out for with the dircmp command.   Some of the files in the directories (i.e. segment files in the segment directories) have a “prologue”.  The prologue can be different between each file yet the actual definitions within that file be identical.  When the dircmp command hits this, it will show it as “different” and not “same”.

      Just an FYI…

      dircmp worked wonders.

      And thanks for the heads up about the prologue.
