This page is designed to be a place to post and answer questions related to the transition of operations from SLAC staff to the FSSC.
Q: How do we access the Subversion repository (as mentioned in the ISOC software summary page) for the ISOC software? The root of the repository is at /nfs/slac/g/glast/online/svnroot. What permissions are needed to access this directory?
Partial answer from Brian on Slack relative to permissions: "I think you need to be added to the `glonline` group" to access the directory
Q: Is responsibility for maintaining the Fermi LAT Portal and its associated Java web applications (http://glast-ground.slac.stanford.edu) moving the FSSC as well or is that staying at SLAC?
Partial answer from Brian (definitive answer still needed):
For the web applications, I think we are having a discussion about that, but in general they stay at SLAC because they rely on Oracle. I think we're still going to try to figure out how support for them will work.
Some of the applications are used by other experiments, so we are still maintaining those (and will have to keep maintaining them)
Q: Is there any documentation on what the SLAC computing center is looking at for containers going forward? There was some talk about it at the software week and IIRC it wasn't docker. I'd like to start getting tied into their plans for the future of the pipeline.
The technology to be used is Singularity. Still need documentation on plans
Q: Reading through the Pipeline II User's Guide and there is a big red box that says "*Everything beyond this point is a big mess and probably wrong.*". Who at SLAC can update that section so it's not a big mess and correct?
Q: What is the timeline for working the FSSC staff into the rotation of watching the pipeline?
Q: Where can I find top level information about various softwares?
http://www.slac.stanford.edu/exp/glast/wb/prod/IA_II_instrAnalysis_Home.htm
Q: is this page - Servers and Aliases - up to date? If not, who at SLAC is responsible for getting it up to date and what is the timeline for doing so?
A: No. Tom Glanzman
Q: Who will be able to grant permissions in the future? When we needed access to the glast and glastraw accounts, Tom Glanzman provided it. For the glastops account, he had Steve Tether do it.
Q: Who do we contact for system related problems? When there was an Oracle database failure, Warren emailed unix-admin@slac.stanford.edu. He then said that "there's nothing more they can do but hope someone from db-admin responds". Who's that?
Q: How/when do you decide that a running job is hung? Is there a set timescale? Does it depend on the type of job? Is this documented anywhere?
Q: How do you close a host in the batch system? What criteria determine if it should be closed or not? Do we ever reopen them? If so, what determines when we should? How is that done?
I think at least the how to open and close hosts is documented somewhere here in confluence, need to find it and link it in. Need answers on determining when to do so.
Q: What are the commands to change the state of running jobs (i.e. from RUN to USUSP and back) in the batch system? Is there a reference somewhere? I'm assuming you need to be on fermilnx-v16 (where the pipeline is running) and logged in as glastraw. Can it be done from the pipeline monitoring page?
A: The bstop and bresume command are used to pause and resume jobs respectively. They require the jobID value of the batch job to run.
You need to be logged in as the pipeline user (glastraw) in order to execute the commands.
You can run on multiple batch jobs at a time with a command similar to:
bresume `bjobs -u glastraw -q medium | awk '/USUSP/{print $1}' | head -100`which would select jobs from user glastraw in the medium queue that have the state USUSP and list out the first 100 jobID values to be submitted to bresume.
Q: Is the OpsLog (http://glast-ground.slac.stanford.edu/elog/Log.jsp?viewTopic=All) still used? (My guess is no since the last entry I can see is from Feb. 2013.) If it is, how do we get login privileges since my SLAC username/password don't work?
A: No.
