I'd bet that if you Googled RMSCDC, you'd get your answer.
It's an effort I've been working on since mid-2009 to allow Attunity to get
access to changed data in RMS files by VMS applications using RMS (indexed
file data was the primary goal but no file format or record format has been
excluded). Some fun (not really, a real head-scratcher it's been) recently
when my RMS CDC code was stressed tested with a 32 processor Itanium blade.
FYI, what I provide is the VMS magic seen in this "graphic" in the gray box
on the left.

There's nothing specific to Attunity's process/products. RMSCDC is simply
a log (a sequential record log of all RMS data changes. It's coordinated
in a cluster environment too, so that in the shared file environment of the
OepnVMS cluster, nothing is logged out of sync.

Yes. Good and bad - RMS is very much embedded within VMS.
In RSX, RMS is a library that you link in to any programs that wants it.
And it's not the only kid in town. You also have FCS, which is a
simpler, smaller library. The file formats are compatible between FCS
and RMS, as far as FCS capabilities cover them. FCS do not handle
indexed files, nor stream files.
And all RSX tools use FCS. (Long story, but FCS was around before RMS
even existed, and RMS is an optional component, so it might not even
exist on all RSX systems.)

Really? So, we surely HAVE come a long way baby with VMS RMS! Still, any
stream format is a ridiculously lame way to differentiate records IMHO. On 04/14/2015 12:24 PM, Johnny Billquist wrote:

Just got back from road trip #1, only have a moment, will get back to
this in the morning. Here is the DSP output:
$ dsp forth.mac
DU:[10,1]FORTH.MAC;1

Cool. So the first, and most obvious, problem, is that the file is
indeed in stream format. So no ordinary RSX tool will touch it with a
five foot pole... Had you
been pulling it from Linux to RSX, and initiated to transfer
from the RSX side, you can tell NFT exactly what format you want for the
file on the local side, when the remote side is a stream format file.
Not sure Linux can do that if you do the transfer from the Linux side.
My next suggestion is to read up on RMSCNV, on how to convert the file.
I can never remember exactly how to use it, so I have to read every time
I want to, but it can convert the file to another format for you.
I can't comment there either; however, if VMS CONVERT help is needed, I'm
available. And now, back to RMS CDC.
I know "RMS", and I know "CDC", I just can't place them in the
same
sentence. I must be missing something...
