Configuration settings for nodes
Use the following configuration settings to specify directories for decision data node resources and to select services that should be enabled when you start Pega Platform.
Apply these settings through the prconfig.xml file. If applicable, you need to configure these settings individually for each node in the cluster.
- dsm/services
- A comma separated list of values that configures the services operating in a Pega Platform node. The possible values are DDS, DataFlow, ADM, and VBD.
- dnode/yaml/commitlog_directory
- The directory where the decision data node commit log is stored. By default, it is configured to <workfolder>/<clustername>/commitlog.
- dnode/yaml/data_file_directories
- The directory location where SSTables are stored. By default, it is configured to <workfolder>/<clustername>/data.
- dnode/yaml/internode_compression
- By default, the traffic between decision data nodes is compressed. You need to turn off compression for PPC64 architecture CPUs or old Linux distributions where the Snappy compression library is unavailable.
