Physical memory and disk space requirements

Each type of node has different physical memory and disk space requirements.

Type of node Disk space requirements
WebLogic Managed Server and WebLogic Admin Server All WebLogic Server nodes (both Managed Servers and the Admin Server) have the following requirements:
  • At least 512MB of free swap space
  • 10GB of available space in the directory defined by the TEMP_FOLDER_PATH property in the BDD configuration file
  • 6GB of available space in the directory defined by the ORACLE_HOME property in the BDD configuration file

Additionally, Managed Servers require at least 5GB of RAM (although your system may require more, depending on the amount of data you will process). The Admin Server requires 6GB of space in the directory defined by the INSTALLER_PATH property in the BDD configuration file.

Dgraph Dgraph nodes have the following requirements:
  • At least 5GB of RAM (your system may require more, depending on the amount of data you will process)
  • 10GB of available space in the directory defined by the TEMP_FOLDER_PATH property in the BDD configuration file
  • 1GB of available space in the directory defined by the ORACLE_HOME property in the BDD configuration file
CDH CDH nodes that will run Data Processing have the following requirements:
  • 3GB of available space in the directory defined by the TEMP_FOLDER_PATH property in the BDD configuration file
  • 2GB of available space in the directory defined by the ORACLE_HOME property in the BDD configuration file
Additionally, the CDH cluster must have the following YARN properties set to at least 4GB:
  • Container Memory (yarn.nodemanager.resource.memory-mb). This is located in the NodeManager Default Group > Resource Management category.
  • Container Memory Maximum (yarn.scheduler.maximum-allocation-mb). This is located in the ResourceManager Default Group > Resource Management category.

To access these properties, open Cloudera Manager, select Clusters > YARN, then click the Configuration tab.
