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. The properties file contains the following information:
- identifier for properties file
properties.owner=LIVE-VM-DEV
- database ############
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/cep_core jdbc.username=root jdbc.password=********
- piwik ############
- Piwik auth-token
piwik.token=******** piwik.serverUrl=http://137.123.234/piwik-dev/
- email-service ############
mailservice.sender=SME E-Compass MailService <xxx@xxx.com> mailservice.smtp_host=mailhost mailservice.smtp_port=25 mailservice.smtp_username=user mailservice.smtp_password=******** mailservice.localhost=dns name of virtual machine
- other ############
httpcomponents.urlReadTimeout=20000 httpcomponents.urlConnectionTimeout=20000 cep.rest.baseUrl=https://dns name of virtual machine/processengine/
- Unit Tests ############
test.email=mail@mail.com
- Address for retrieving conversion rate ############
uma.address = http://ecompass.com
- price monitor ############
price.service.address = http://pricemonitor.com
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?
