The following sections describe how to run WSO2 Enterprise Integrator (WSO2 EI).

Info
  • When starting the analytics profile, you may intermittently get a BindException error (i.e., Cannot assign requested address: Service 'sparkDriver' failed after 16 retries!) if the Apache Spark client does not start properly (due to an issue in socket binding on computers with multiple IP interfaces). Add the same hostname that you specify in the /etc/hosts file of your system as the value of the <HostName> element in the <EI_HOME>/wso2/analytics/conf/carbon.xml file to rectify this.
  • If you are using IBM JDK 1.8, change the value of the org.owasp.csrfguard.PRNG.Provider property to 'IBMJCE' in the <EI_HOME>wso2/analytics/conf/security/Owasp.CsrfGuard.Carbon.properties file.
  • If you get the Caused by: java.lang.IllegalArgumentException: java.lang.NoClassDefFoundError: Could not initialize class org.xerial.snappy.Snappy exception when starting the Analytics in certain environments such as Windows or Red Hat linux, download the snappy-java_1.1.1.7.jar file and add it to the <EI_HOME>/lib directory.
  1. Open a command prompt (or a shell in Linux) and go to the <EI_HOME>\wso2\analytics\bin directory.
  2. Execute one of the following:

    • On Linux/Mac OS:sh wso2server.sh

    • On Windows:wso2server.bat

  3. The operation log keeps running until the Analytics profile starts, which usually takes several seconds. Wait until the Analytics profile fully boots up and displays a message similar to "WSO2 Carbon started in n seconds."
