Kafka-based AI example using DayTrader

Components of this demo project

The installation of this demo project installs all of the following on IBM i:

• DayTrader, a sample application that simulates a stock exchange
• Apache JMeter, which can be used to stress-test the application by executing a large amount of stock trades
• Websocket extensions for JMeter, needed for use with DayTrader
• OpenLiberty, a server runtime (used to run DayTrader)
• Service Commander, a utility to help manage which jobs are running
• Apache Kafka, message-oriented middleware that delivers a distributed streaming platform
• Apache Zookeeper, a service for powering distributed applications (used by Kafka)
• Apache Camel, an integration library (used for integrating Db2 transactions with Kafka)

This project also requires an IBM i user profile and schema to be created of the same name, which the installation script will create. These are used by the DayTrader application.

IBM i component Installation

• Installation requires that you have the yum ecosystem installed (see http://ibm.biz/ibmi-rpms)
• You should run any documented commands in an SSH terminal session

Standard install (with Internet access)

First, install the kafka-ai-demo-installer RPM, which will ensure that any requisites are installed (Service Commander will need to be installed separately, as shown below)

yum install https://github.com/ThePrez/Kafka-DayTrader-AI-example/releases/download/v0.0.2/kafka-ai-demo-installer-0.0.2-0.ibmi7.2.ppc64.rpm

That RPM will place the installer script at /QOpenSys/QIBM/UserData/Kafka-AI-Demo-installer/install.sh

There are several items you can customize about your installation through the use of the following environment variables:

• INSTALLDIR: The installation directory (default: /QOpenSys/OCPDT_demo)
• INSTALLSCHEMA: The schema to create for use by DayTrader. A user profile of the same name will be created. DO NOT USE a name for which an existing user profile exists!! (default: OCPDT)

For example, to install to /QOpenSys/ocp2, use schema OCP2, and create user profile OCP2, run the following command: INSTALLDIR=/QOpenSys/ocp2 INSTALLSCHEMA=OCP2 /QOpenSys/QIBM/UserData/Kafka-AI-Demo-installer/install.sh

When the install completes, it should provide you with output similar to the following, providing instructions on how to start/stop the demo and run Apache JMeter for stress testing :

DONE!!
   Demo has been installed to:
      Schema 'OCP2'
      Directory '/QOpenSys/ocp2'

   To start the demo, sign in as JGORZINS and run:
      /QOpenSys/pkgs/bin/sc start group:aikafka
   To stop the demo, sign in as JGORZINS and run:
      /QOpenSys/pkgs/bin/sc stop group:aikafka
   To stress test with Apache JMeter:
      /QOpenSys/ocp2/jmeter/bin/jmeter -n -t /QOpenSys/ocp2/daytrader7.jmx -JHOST=127.0.0.1 -JPORT=10200 -JTHREADS=10 -JDURATION=120 -l jmeter_log.txt

Offline install (without Internet access) -- WARNING: untested and unlikely to work!

First, download the following files and upload them to a directory on IBM i:

• https://github.com/ThePrez/Kafka-DayTrader-AI-example/releases/download/v0.0.1/kafka-ai-demo-installer-offline-0.0.2-0.ibmi7.2.ppc64.rpm

Then, cd to the directory where you have placed these RPMs and run the following commands to install them (you may need to also install other requisite RPMs):

yum install ./sc-0.4.1-0.ibmi7.2.ppc64.rpm
yum install ./kafka-ai-demo-installer-offline-0.0.1-0.ibmi7.2.ppc64.rpm

These RPMs will place the offline installer script at /QOpenSys/QIBM/UserData/Kafka-AI-Demo-installer/install-offline.sh

There are several items you can customize about your installation through the use of the following environment variables:

• INSTALLDIR: The installation directory
• INSTALLSCHEMA: The schema to create for use by DayTrader
• INSTALLUSER: The user profile to create for use by DayTrader

For example, to install to /QOpenSys/ocp2, use schema OCP2, and create user profile JESSE, run the following command: INSTALLDIR=/QOpenSys/ocp2 INSTALLSCHEMA=OCP2 INSTALLUSER=JESSE /QOpenSys/QIBM/UserData/Kafka-AI-Demo-installer/install-offline.sh

When the install completes, it should provide you with output similar to the following, providing instructions on how to start/stop the demo and run Apache JMeter for stress testing :

DONE!!
   Demo has been installed to:
      Schema 'OCP2'
      Directory '/QOpenSys/ocp2'

   To start the demo, sign in as JGORZINS and run:
      /QOpenSys/pkgs/bin/sc start group:aikafka
   To stop the demo, sign in as JGORZINS and run:
      /QOpenSys/pkgs/bin/sc stop group:aikafka
   To stress test with Apache JMeter:
      /QOpenSys/ocp2/jmeter/bin/jmeter -n -t /QOpenSys/ocp2/daytrader7.jmx -JHOST=127.0.0.1 -JPORT=10200 -JTHREADS=10 -JDURATION=120 -l jmeter_log.txt
