Unable to start WSO2 API Manager with Traffic Manager Profile

Question

I am configuring the open-source version of WSO2 API Manager 3.1.0 in Distributed Setup. I have completed all the configurations, but when I try to start the API manager with Traffic Manager (or any other profile as a matter of fact), I am getting the below error.

 org.apache.axis2.AxisFault: Exception occured while loading the Axis configuration from /wso2am-3.1.0/repository/conf/axis2/axis2.xml

Please let me know what changes I have to do in order to start the servers without any issues.

Thanks in advance.

Answer 1

try following these steps to avoid this error

1. Unzip a fresh distribution, do not start it,
2. Navigate to APIM-HOME/bin folder and run sh profileSetup.sh -Dprofile=traffic-manager This will remove files and configs not required for traffic manager
3. Next add your configuration in deployment.toml Only shared db will be needed for traffic manager and keystore configs
4. Start the server sh wso2server.sh -Dprofile=traffic-manager

Answer 2

Try to follow this document when you set up these distribute setup profiles. https://apim.docs.wso2.com/en/next/install-and-setup/setup/distributed-deployment/product-profiles/#method-1-optimizing-before-starting-the-server
