computationPrototype

This project implements an HCD (Hardware Control Daemon) and an Assembly using TMT Common Software (CSW) APIs.

Subprojects

• aps-computationprototypeassembly - an assembly that talks to the computationPrototype HCD
• aps-computationprototypehcd - an HCD that talks to the computationPrototype hardware
• aps-computationprototypedeploy - for starting/deploying HCDs and assemblies

Upgrading CSW Version

project/build.properties file contains csw.version property which indicates CSW version number. Updating csw.version property will make sure that CSW services as well as library dependency for HCD and Assembly modules are using same CSW version.

Build Instructions

The build is based on sbt and depends on libraries generated from the csw project.

See here for instructions on installing sbt.

CSW Prerequisites for running Components

The CSW services need to be running before starting the components. This is done by starting the csw-services. If you are not building csw from the sources, you can run csw-services as follows:

• Install coursier using steps described here and add TMT channel.
• Run cs install csw-services. This will create an executable file named csw-services in the default installation directory.
• Run csw-services start command to start all the CSW services i.e. Location, Config, Event, Alarm and Database Service
• Run csw-services --help to get more information.

Note: while running the csw-services use the csw version from project/build.properties

Changes to add a the Algorithms Library Jar to build

Changes to Dependencies.scala, use the following block:

val Computationprototypeassembly = Seq(
CSW.`csw-framework`,
CSW.`csw-testkit` % Test,
Libs.`scalatest` % Test,
Libs.`junit4-interface` % Test,
Libs.`testng-6-7` % Test,
"org.tmt.aps.peas" % "algorithm-lib" % "1.0.0"
)

Changes in Common.scala, update the propertiesSettings by adding mavelLocal resolver and adding /opt/apps/lib to the java.library.path

    resolvers += "jitpack" at "https://jitpack.io",
    resolvers += Resolver.mavenLocal,
    version := "0.1.0",
    fork := true,
    javaOptions += "-Djava.library.path=/opt/apps/lib",

Setting the javaOptions allows the JVM to find the shared library assuming library is in /opt/apps/lib

Running the Assembly

Run the container cmd script with arguments. For example:

• Run the Assembly in a standalone mode with a local config file (The standalone config format is different than the container format):

sbt "aps-computationprototypedeploy/runMain aps.computationprototypedeploy.ComputationprototypeContainerCmdApp --local ./src/main/resources/JComputationprototypeassemblyStandalone.conf"
