in PRPC 7.2.1 is Cassandra now a separate service in all architectures?

I have just set up a new test environment (Linux/Tomcat/Oracle) with PRPC 7.2.1, and was surprised when configuring the DNode, that now a separate process (JVM) is created in Tomcat.

the normal Apache JVM that hosts the Pega .war files ...

/usr/java/jdk1.8.0_77/bin/java  -Djava.awt.headless=true -Xms2048m -Xmx4096m ....

and once a DNode is activitated this shows up ...

/usr/java/jdk1.8.0_77/jre/bin/java -ea -javaagent:/var/apache/apache-tomcat-8.0.33/cassandra/lib/jamm-0.3.0.jar  -Xms2398M -Xmx2398M ... org.apache.cassandra.service.CassandraDaemon

I was surprised to see that the whole Landing Page configuration surrounding DNodes changed completely from 7.2 to 7.2.1, but my initial concern surrounding this is has more to do with controlling this new JVM, as it is independent of the Tomcat start/stop process, and I did not see anything in the manuals that talk about this new process.

  1. is there a provided safe mechanism to start/stop this JVM?
  2. I am on Tomcat, but what can I expect to see when I move to a WebSphere or WebLogic environment, is this still just going to be an external Java process?
