Body
Based on talking to some HPC specialists at work and some Google searching on the subject (I also wanted to resume a job ID), it's not really possible if you've already submitted the job. You can <code>qlogin -q <node name></code> into the node again, but you cannot resume the job on the shell screen. If you are thinking of starting a new qlogin job, but you would like to be able to resume it at some future point, then you can use <code>screen</code> to do this. <ol> <li>Before you write <code>qlogin</code> into the command line at the front-end node, write <code>screen</code>. It should completely clear the terminal screen.</li> <li>Now <code>qlogin</code> and put in your job script interactively.</li> <li>Once your job has started running and you want to leave for a bit, press and hold Cntl while you press A and D. It should say that your screen was detached and take you back to the front-end node. If you <code>qstat</code> now, you should see your job running.</li> <li>When you want to resume the job ID (see the running process on the terminal screen), in the front-end node write <code>screen -r</code>. You should be able to see your running process in the terminal again.</li> </ol> Note: if you do this several times and you accumulate multiple screens by accident (happens to me every time), when you <code>screen -r</code> you will get multiple choices instead of automatically resuming the one you want. To try each one out, type <code>screen -r <name of screen listed></code> one at a time until you find the one you want (detach as specified above). To get rid of the extra screens, write <code>screen -D -r <name></code>. Hope this helps.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
