These are instructions, software snapshots and slides used for CSS training at
If you only want to learn about using CSS as an end user or to create BOY displays, you need the following:
Download the "Basic EPICS" CSS from http://ics-web.sns.ornl.gov/css/products.html
Verify that you can start it. If it does not start up, see comments regarding Java at http://ics-web.sns.ornl.gov/css/issues.html
At some training sites, you can connect to a network where EPICS process variables, archived data etc. are available.
At SLAC, you will be on a visitor network. To access example data you need to execute an EPICS soft IOC on your own computer. Example soft IOCs for various operating systems are listed below.
For CSS development you need the following:
Check that the command
java -versiondisplays a version number of 1.7 or higher with "HotSpot", "Sun" or "Oracle" in the name. Not version 1.5, not GNU.
If you don't have java installed, you should probably install the JDK, i.e. a development kit instead of the plain JRE runtime. It is suggested to point the JAVA_HOME environment variable to the base directory of your Java installation, and you should be able to call "java" from the command line, which typically means that your PATH contains $JAVA_HOME/bin. Eclipse has ways to find java even if it is not on the PATH, but as a developer you are best off when you know exactly which Java you are using.
Eclipse IDE for "RCP and RAP Developers"
Download the version listed under "Tools" below. With Java properly installed, eclipse should start up without error messages.
CSS Source Snapshot
Download the latest "SNS Sources" from http://ics-web.sns.ornl.gov/css/products.html
The above Java and Eclipse setup will allow you to participate in most of the training. It represents what a CSS developer needs in an environment where there is already a shared server for JMS and an RDB like MySQL.
If you want to duplicate a complete standalone system on your training computer, you would also need the following:
Install for example MySQL and assert that you can connect to it as the RDB super user:
mysql -h localhost -u root -p
When unpacking the apache-activemq-5.5.0-bin.tar.gz, there should be a 'bin' dir with an activemq command.
# Check that there is no JMS server running: # ... should not see any LISTEN entry netstat -an | fgrep 61616 # Start Active MQ JMS: bin/activemq start # Now there should be a LISTEN entry netstat -an | fgrep 61616 # Should show something like "BrokerNname = localhost" # If you get many errors instead of "BrokerNname = localhost", # check which Java you are using. # OpenJDK may not work. Use the Sun/Oracle JDK bin/activemq list # In case of problems, check data/activemq.log # Stop, then the LISTEN entry should vanish bin/activemq stop netstat -an | fgrep 61616 # Should see a very long list of errors bin/activemq list
These binaries contain the
commands and associated shared libraries from EPICS base.
In addition, there is a command
runIOC.sh that will execute a soft IOC for
several example databases.
Since installations of Linux vary, the examples might not work for you.
For example, you may need to install the
if it is not already included in your Linux setup.
The binaries offered here do also not include the 'CA Repeater'.
If you prefer to have a complete setup of EPICS base, please install it from
These days most computers already include Java.
java -version on the command line.
If it shows a version number of 1.6 or higher with "HotSpot", "Sun" or "Oracle"
in the name, you are OK.
Otherwise try these, or go to Oracle's Java JDK download page:
Download the current "Eclipse for RCP and RAP Developers" from http://www.eclipse.org/downloads/. At the time of this writing, the Eclipse source code still requires "Eclipse Indigo (3.7.2)", so you either use that as the IDE, or you use a current Eclipse 4.x IDE, but set the target platform to 3.7.2.
Note that these versions work OK with the Sun/Oracle Java 1.6 listed above, but seem to have problems with OpenJDK (IcedTea 6) as well as Sun/Oracle Java 1.7
This book is meant to serve as a guide for those who need to install, maintain and extend CSS.
