Software Licenses
Please indicate if a commercial provider would need to buy commercial licenses of a certain software used for operating the service and – if so – what cost this may produce approximately
- EsperTech Java library (www.espertech.com): Cost for a commercial license range between USD $300 and USD $1800 per perpetual Java Virtual Machine (JVM).
- MySQL Community Edition (www.mysql.com/products/community): free of charge.
- Windows 8 64-bit: < € 100
OS Environment Variables
JAVA_HOME: path to Java installation e.g. C:\Program Files (x86)\Java\jdk1.8.0_51
Path: should contain path to Java bin folder e.g. C:\Program Files (x86)\Java\jdk1.8.0_51\bin
Installation
Java: Latest Java JDK (not JRE) has to be installed. File and instructions can be found on http://www.oracle.com/technetwork/java/javase/downloads/index.html JAVA_HOME and Path environment variables must be set.
MySQL Community Edition: File and instructions can be found on http://dev.mysql.com/downloads/
Java Jetty Server and Application: Copy war and jar file in any folder and start the application by clicking on the jar-File.
Preparation
Before starting the installation a valid property file has to be provided. An example of such a properties file is attached to this wiki.
This property file has to be stored on the virtual machine. To define the path to this property file you can start the application with the following command: java -jar -DARGS_CONFIG_CEP="C:\ecompass.properties"

Limitations of the service
- With which parameters does the service scale?
How many concurrent E-Shops, how many concurrent products and how many users/E-Shop customers are possible without causing loss in quality/speed for the hardware described above?
- Parameters relevant for the scaling of this module are the overall number of users of all E-Shops and the number of rules. Each rule generates one request every ten minutes, i.e. the rules are checked every ten minutes. Each request takes 100 - 200 ms of time. So in ten minutes a maximum of 3000 request should be possible without further parallelization. There is one special kind of rule, which is the voucher rule (i.e. if a user shows a certain behaviour on the E-Shop a voucher is shown to him). This rule generates traffic depending on user behaviour, which means that this is not predictable. Therefore the above estimate can only give an orientation, not a guaranteed limit and one should always keep reserves for situations in which many users (over all E-Shops) show a behaviour that triggers a voucher rule.
- If higher scaling was wanted, which of the hardware parameters would need to be increased?
- The number of CPUs/CPU cores is the most critical. Eventually RAM and Storage may need to be increased also.
- What else would be adjusted for higher scalability?
- In order to make use of more CPU cores the software code would need to be parallelized, which is currently not the case.
- Which further configuration would be necessary?
