---++ Grid User Interface

Every PPE desktop (both SL4x or SL5x) can act as a <a rel="nofollow" href="http://glite.web.cern.ch/glite/" title="http://glite.web.cern.ch/glite/">EGEE gLite UI</a>. The User Interface (UI) tools, dq2-client and GANGA are installed on SL4x desktops in <code>/data/ppe01/sl44/i386/grid</code>. For SL5x desktops the User Interface (UI) tools, dq2-client , but not GANGA are installed in <code>/data/ppe01/sl5x/x86_64/grid</code>

---++ Using the UI

First source the appropriate setup file depending on your current shell and sl version of your machine.

To check your current shell use: <code>echo $SHELL</code>

To check the version of SL use: <code>cat /etc/redhat-release</code>

<table width="100%" cellspacing="0">
<tr><td bgcolor="lightgreen">For SL4x and bash or zsh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.sh</td></tr>
<tr><td bgcolor="lightgreen">For SL4x and tcsh or csh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.csh</td></tr>
</table>

<table width="100%" cellspacing="0">
<tr><td bgcolor="lightgreen">For SL5x and bash or zsh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source /data/ppe01/sl5x/x86_64/grid/glite-ui/latest/external/etc/profile.d/grid-env.sh</td></tr>
<tr><td bgcolor="lightgreen">For SL5x and tcsh or csh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source /data/ppe01/sl5x/x86_64/grid/glite-ui/latest/external/etc/profile.d/grid-env.csh</td></tr>
</table>

<a name="Using_the_dq2-client"></a>
---++ Using the dq2-client

Setup the UI as mentioned in the previous section.

Again depending on SL version and shell source a setup file:

<table width="100%" cellspacing="0">
<tr><td bgcolor="lightgreen">For SL4x and bash or zsh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source /data/ppe01/sl44/i386/grid/dq2-client/setup.sh</td></tr>
<tr><td bgcolor="lightgreen">For SL4x and tcsh or csh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source /data/ppe01/sl44/i386/grid/dq2-client/setup.csh</td></tr>
</table>

<table width="100%" cellspacing="0">
<tr><td bgcolor="lightgreen">For SL5x and bash or zsh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source data/ppe01/sl5x/x86_64/grid/dq2-client/setup.sh</td></tr>
<tr><td bgcolor="lightgreen">For SL5x and tcsh or csh shells:</td></tr>
<tr><td bgcolor="lightblue">$ source data/ppe01/sl5x/x86_64/grid/dq2-client/setup.csh</td></tr>
</table>

Then create a voms proxy
<pre>voms-proxy-init -voms atlas </pre>

and use the <a rel="nofollow" href="https://twiki.cern.ch/twiki/bin/view/Atlas/DistributedDataManagement" title="https://twiki.cern.ch/twiki/bin/view/Atlas/DistributedDataManagement">dq2 Tools</a> as needed. <a name="Using_GANGA"></a>#

Now try these simple commands:

=dq2-ls alpgen.105762.ttbarlnlnNp2_lowQ=

and to show the individual files (This may not work on SL5 machines)

=dq2-ls -f alpgen.105762.ttbarlnlnNp2_lowQ=
