Running Etrax Thresholds Control

Steps to compile code

1. login to any hades machine as scs :
   • ssh lxg0434 -l scs
2. change to etrax directory
   • cd /u/scs/epics_apps/EtraxTest
3. run setup
   • . ./setup.sh
4. make
   • make clean && make
5. If successful, remove binary and copy code on target system's file server (you have to enter twice (correctly) the password of hadaq, copy the whole code block below)
   • 
ssh hadaq@lxhadesdaq '   
   if [ -d /var/diskless/etrax_fs/epics/epics_apps/EtraxTest/bin ];
   then
      rm -r /var/diskless/etrax_fs/epics/epics_apps/EtraxTest/bin;
   fi' &&
echo removed binary &&
scp -r /u/scs/epics_apps/EtraxTest/{bin,db,dbd,iocBoot} hadaq@lxhadesdaq.gsi.de:/var/diskless/etrax_fs/epics/epics_apps/EtraxTest/
 
6. logout
   • exit

... or all together:


ssh lxg0434 -l scs
cd /u/scs/epics_apps/EtraxTest
. ./setup.sh
make clean && make
ssh hadaq@lxhadesdaq '   
   if [ -d /var/diskless/etrax_fs/epics/epics_apps/EtraxTest/bin ];
   then
      rm -r /var/diskless/etrax_fs/epics/epics_apps/EtraxTest/bin;
   fi' &&
echo removed binary &&
scp -r /u/scs/epics_apps/EtraxTest/{bin,db,dbd,iocBoot} hadaq@lxhadesdaq.gsi.de:/var/diskless/etrax_fs/epics/epics_apps/EtraxTest/
 

That's all!

Steps to start up

Version for RPC test setup May/June 2008:

Use the script rpc_may08_epics_quickfix (local copy) provided by Michael Traxler on lxhadesdaq,
provided your correct st-RpcThreshold-S3TRBxxx--SubEventIdyyy.cmd startup files are prepared
(xxx: TRB number, yyy: SubEventId number):

1. login to lxhadesdaq
   • ssh -l hadaq lxhadesdaq.gsi.de
2. execute at any place rpc_may08_epics_quickfix

   start

   rpc_may08_epics_quickfix start

   stop

   rpc_may08_epics_quickfix stop

Basic/test/preparatory phase version

1. login to your target machine (e.g. etrax023),(user: root)
   • • telnet etrax023
   1. Change to iocboot directory of epics
      • cd /home/hadaq/epics/epics_apps/EtraxTest/iocBoot/iocetrax
   2. Provided your correct st-RpcThreshold-S3TRBxxx--SubEventIdyyy.cmd startup file is prepared, so first check in the current directory for st-RpcThreshold-S3TRBxxx--SubEventIdyyy.cmd
      (xxx: TRB number, yyy: SubEventId number),
      • ls
   3. Start the IOC
      • ../../bin/linux-cris_v32/EtraxTest st-RpcThreshold-S3TRB0--SubEventId809_master.cmd
   4. Keep it running.
      • DO NOT CLOSE THE WINDOW! (Other solution will come) (see solution above using internally screen)

Steps to restart

1. Use one of those commands to stop the epics IOC application
   • exit , CTRL+Z
2. Killall instances of EtraxTest (assuming you are the only user running EtraxTest)
   • killall -9 EtraxTest
3. Restart:
   • ../../bin/linux-cris_v32/EtraxTest st-RpcThreshold-S3TRB0--SubEventId809.cmd

Caveats / Tips & Tricks

When copying with scp you have to look at the protocol ...

Sometimes the binaries stay write-only.
Therefore you should have been using ssh hadaq@lxhadesdaq 'rm -r /var/diskless/etrax_fs/epics/epics_apps/EtraxTest/bin retry it.

How do I know, that a new database file has been created when having performed the steps to compile ?

• • on linux:
    • have a look at the directory /u/scs/epics_apps/EtraxTest/db to the newest files of pattern ...SxTRBy...SubEvtIdz (x:sector, y:trb, z:id)
  • on etrax:
    • have a look at the directory /home/hadaq/epics/epics_apps/EtraxTest/db

In case you are using a new Combination of SECTORxTRBy and SubEventId abc ...

... then you have to create a new cmd file on the ETRAX using the script createCmdFile.sh on the TRB/ETRAX (if you cannot find it there, copy those local files to the corresponding directories)

• • files
    • createCmdFile.sh: Script to create from template cmd files
    • st-RpcThreshold-SsTRBt--SubEventIdXXX.cmd.template: matching template file for script

steps to do:

1. 1. 1. login to your target machine(s) (e.g. etrax023),(user: root)
         • telnet etrax023
      2. Change to iocboot directory of epics
         • cd /home/hadaq/epics/epics_apps/EtraxTest/iocBoot/iocetrax
      3. execute createCmdFile.sh
         • usage: $ createCmdFile.sh : will give you the help how to use it
