A collection of useful scripts to use with CODA

coda_scripts

A collection scripts for use with small scale DAQs running CODA 3

Install and Configuration

• Setup host ssh key for automated login to CODA component clients.

  • ssh-keygen Generate a New SSH Key

• Install scripts on CODA 3 Platform host, ROC and PEB clients.

  • With git

    git clone [e-mail]:JeffersonLab/coda_scripts.git ~/coda3/coda_scripts-master
    

  • From zip

    unzip coda_scripts-master.zip ~/coda3/
    

  • If you're not sharing this directory with the CODA Components (e.g. with NFS), repeat this step for each component.

• Configure environment variables in setupCODA3.tcsh or setupCODA3.bash

  • These environment variables are specific to your setup.

    setenv CODA /site/coda/3.10
    source $CODA/.setup
    
    setenv SESSION session
    setenv EXPID expid
    
    setenv COOL_HOME ${HOME}/coda3/cool
    setenv JAVA_HOME ${HOME}/jdk1.8.0_152
    
    setenv REMEX_CMSG_HOST thishost.jlab.org
    setenv REMEX_CMSG_PASSWORD ${EXPID}
    
    setenv CODA_COMPONENT_TABLE ${CODA_CONFIG}/config/${EXPID}/coda_component_table.cfg
    

• Source the setupCODA3.{tcsh,bash} in shell setup file for each DAQ component

  • In .bashrc

    export CODA_CONFIG=~/coda3/coda_scripts-master
    source $CODA_CONFIG/setupCODA3.bash
    

  • In .tcshrc

    setenv CODA_CONFIG=~/coda3/coda_scripts-master
    source $CODA_CONFIG/setupCODA3.tcsh
    

  • Modify the config file adding each DAQ component on the host

    • The file defined by $CODA_COMPONENT_TABLE specifies the components that will interact with these scripts

    • File format:

      HOSTNAME COMPONENT_TYPE COMPONENT_NAME OPTIONAL_ARG

    • For example, I have a PEB named PEB1 running on daqpc1:

      daqpc1 PEB PEB1

    • For example, I have a ROC named ROC2 running on daqroc2 and needs to run a tcl script to set it's randy factor on startup:

      daqroc2 ROC ROC2 -t setrf.tcl

Howto Use

• If you have an empty COOL_HOME (otherwise, skip this step)

  • Run jcedit
  • Create new COOL database
  • Expert -> Session -> New
    • Enter SESSION name (matches that defined in environment)

• Launch CODA3 and its components

    startCoda
  

• Restart ONLY the PEB and ROC components

    restartStuff
  

• Kill ALL CODA components started by startCoda
