Configure prconfig.xml settings as a tomcat property in tomcat configuration file
We have a few configurations which can be moved out of prconfig.xml file into tomcat configuration file as a tomcat property, like the below mentioned properties which can be used to control tempdir and pega log folders.
1. pega.logs 2. pega.tempdir
I would like to provide a few configurations of Kafka in the tomcat. Where can i get the property name
I'm looking at the below two configurations:
- dsm/services/stream/pyUnpackBasePath
- dsm/services/stream/pyBaseLogPath
The below mentioned article talks about prconfig.xml or a DSS but not a shorthand tomcat property.

Usually kafka configurations can be adjusted in kafka.properties file. However, PEGA when it initially starts kafka server it autogenerates the file. I.e. it overwrites it
So any changes made to server.Properties won't take effect. However you can override them in PRconfig/DSS.
As per the use case as PRconfig cannot be modified and DSS takes effect on all nodes.The only savior here is JVM arguments, using -DNodeSettings you can specify these things as JVM takes precedence over PRconfig/DSS.
Sample:
-DNodeSettings=dsm/services/stream/pyBaseLogPath=/usr/local/tomcat/kafka_logs;dsm/services/stream/pyUnpackBasePath=/usr/local/tomcat/kafka_data

The link you quoted has a fairly complete stream service (kafka) related prconfig settings. At the minimal,
set -DNodeType=Stream and prconfig/dsm/services/stream/pyBaseLogPath.
Use other configuration per your own environment if needed - e.g., if you have multiple stream nodes on the same host, you would have to use pyBrokerPort/pyKeeperPort/pyJmxPort to avoid port conflict.
