This project is a part of X-Environment (Integrated Control System for High-throughput Tomography experiments). X-Environment is a bunch of components that server two main goals:
- Collect data during the High throughput Tomography experiment in a non-disturbing way (does not disturb experiment)
- Provide high level abstraction for beamline scientist to control the experiment
This Tango server corresponds to the first goal. It aggregates data from upstream Tango and/or TINE servers it acts as an intermediate buffer for the collected data.
- Java 11 server environment
- Tango 9+
goto {SS_ROOT}/devkit and execute install.bat(.sh)
for older versions manually download and install tine and TangoAPI jars.
There are still some tests that are strictly environment depended (e.g. TangoClientTest) to build the project simply turn off tests in maven: mvn package -Dmaven.test.skip=true
As the for version 1.8 there is no way to run StatusServer without Tango installed. At least programmatically. But it is possible to adjust code so it will start:
- change the code of the Launcher.java (see below)
- change the code of the StatusServerClass.java (see below)
- execute {{{mvn clean package}}}
- deploy
- run with additional JVM parameter: -DOAPort=56234 (see below full command)
In Launcher.java change main method:
#!java
Launcher.java
public static void main(String[] args) {
...
log.info("Initializing Tango framework...");
Util util = Util.init(new String[]{configuration.getInstanceName(),"-nodb","-dlist","development/local/0"}, configuration.getServerName());
util.add_class(configuration.getServerName());
Util.set_serial_model(TangoConst.NO_SYNC);
log.info("Done.");
...
}
In StatusServerClass.java comment write_class_property and get_class_property methods call in the constructor (StatusServerClass(String s))
#!java
StatusServerClass.java
...
protected StatusServerClass(String s) throws DevFailed {
super(s);
// write_class_property();
// get_class_property();
}
...
To run StatusServer use the following command:
java -DXmx1G -Dss.home={SS_HOME} -DOAPort=56234 wpn.hdri.ss.Launcher --config {PATH_TO_CONFIG}
