Hi Subhav:<br>
<br>
There is a test workflow for Data Grid File Transfer actor at
<a class="moz-txt-link-freetext" href="https://code.kepler-project.org/code/kepler/trunk/workflows/srb/datagridtest.xml">https://code.kepler-project.org/code/kepler/trunk/workflows/srb/datagridtest.xml</a>.
Yet the server failed to response when I just test it. :(<br>
<br>
About the scenario, the possible workflows depend on many
conditions, such as the server/client operation system, the connection
protocols supported between server and clients, and which kind of
execution you want to execute on the server. Do you mean client or
server which has windows environment? The easiest workflow I can
imagine is using SSH File Copier (org.kepler.actor.ssh.FileCopier) or
SCP (org.geon.Scp) actor to copy file and use SSH to Execute
(org.kepler.actor.ssh.ExecuteCmd) or SSH Execute cmd
(org.sdm.spa.Ssh2Exec) actor to execute on the server. Please try. <br>
<br>
BTW: you do not need to send emails to both kepler-users and
kepler-dev, since most Kepler developers are in both mailing lists.<br>

<div>So how do I go about using the Data Grid File Transfer actor?
<div><br>
<div>Do I need an SDSC account? Are there any sample workflows which
I can see to understand and learn? (The Globus actors don't work and
the SRB actors require me to have an account)</div>
<div><br>
</div>
<div>My primary interest would be regarding the scenario mentioned in
the User Manual in a Windows environment. These files may be excel
files, for eg, which are being transferred to the server, some
modifications being made there, and copied back to the client.</div>
<div><br>
</div>
<div>Just for reference, I am pasting the scenario again mentioned in
the manual: <span class="Apple-style-span"

very common scenario is the following: a user needs to copy (or stage)

remote resource, run a computational experiment on that remote</span></div>

<div>resource, and then fetch the results back to the local
environment or copy them to another</div>
<div>resource/database."</div>
<div><br>
</div>
<div>...Including Kepler-Dev in the loop too..</div>

Hi Matt,<br>
<br>
DICE group (<a moz-do-not-send="true"
href="http://diceresearch.org/DICE_Site/Home/Home.html" target="_blank">http://diceresearch.org/DICE_Site/Home/Home.html</a>)
has
iRODS service now. Yet the previous SRB service is still there. My
tests two months ago for SRB actors still work. For iRODS service, they
implemented a new actor called DataGridTransfer. I checked it in Kepler
1.x. It's url at kepler trunk is
<a moz-do-not-send="true"
href="https://code.kepler-project.org/code/kepler/trunk/modules/actors/src/org/srb/DataGridTransfer.java"
target="_blank">https://code.kepler-project.org/code/kepler/trunk/modules/actors/src/org/srb/DataGridTransfer.java</a>.
<br>
<br>
The DataGridFileTransfer actor has functionality similar to the
SRB/IRODS commands, namely Sget, Sput, iget, and iput.
DataGridFileTransfer allows users to copy one or more objects from one
local/remote file system to another local/remote file system. The
following actor expects as input a reference to local or remote file
systems support by the Jargon API . This reference connection is
created from the source and destination URL values, Currently available
file system URLs are, <a moz-do-not-send="true">file:///myDir/myfile.txt</a>,
<a moz-do-not-send="true"
href="mailto:irods://username:password@myhost.org:1247/myDir/myfile.txt"

<blockquote type="cite">I've learned that SDSC seems to be
migrating away from the
SRB and instead setting up a new iRODS service. Certainly that may
affect the accounts that people use, and it may also have implications
for whether the SRB actors continue to function properly -- I'm not
sure if the iRODS server uses the same API as the SRB server, so its
not clear to me if they will be backwards compatible. Ilkay -- do you
know who might be able to clarify compatibility plans with the new
service at SDSC?<br>

a lot, Jianwu. I was able to download these workflows but unable to run
