We can run N of hybris instances till machine memory permits. but we need to have a separate tomcat port for each instance. the below ports are unique for each instance. We should add the properties below in each instance’s local property file with unique values.
tomcat.http.port=7001
tomcat.ssl.port=7002
tomcat.ajp.port=7009
tomcat.jmx.port=7003
tomcat.jmx.server.port=7004
