Disk space requirements

Each type of BDD node has specific disk space requirements.

The following table lists the minimum amounts of space required to install BDD on each type of node.

Important: Be aware that these are the amounts required by the product itself and don't account for storing or processing data—full-scale installations will require more. You should work with your Oracle representative to determine an appropriate amount for your processing needs before installing.
Type of node Requirements
Install machine/WebLogic Admin Server The install machine, which will become the Admin Server after you install, has the following requirements:
  • At least 512MB of free swap space. If the Admin Server doesn't meet this requirement, be sure to set the WLS_NO_SWAP property in BDD's configuration file to TRUE.
  • 10GB of available space in the directory defined by the TEMP_FOLDER_PATH property in BDD's configuration file.
  • 6GB of available space in the directory defined by the ORACLE_HOME property in BDD's configuration file.
  • At least 10GB of available space in the directory defined by the INSTALLER_PATH property in BDD's configuration file.
WebLogic Managed Server All Managed Servers have the following requirements:
  • At least 512MB of free swap space for WebLogic Server. If your Managed Servers don't meet this requirement, be sure to set the WLS_NO_SWAP property in BDD's configuration file to TRUE.
  • At least 39GB of virtual memory for the Transform Service. Note that installing the Transform Service on Managed Servers is recommended, but not required. If you decide to host it on a different type of node, verify that it meets this requirement.
  • 10GB of available space in the directory defined by the TEMP_FOLDER_PATH property in BDD's configuration file.
  • 6GB of available space in the directory defined by the ORACLE_HOME property in BDD's configuration file.
Dgraph Dgraph nodes have the following requirements:
  • 10GB of available space in the directory defined by the TEMP_FOLDER_PATH property in BDD's configuration file.
  • 1GB of available space in the directory defined by the ORACLE_HOME property in BDD's configuration file.
YARN worker nodes YARN worker nodes, which will run Data Processing jobs, have the following requirements:
  • 3GB of available space in the directory defined by the TEMP_FOLDER_PATH property in BDD's configuration file.
  • 2GB of available space in the directory defined by the ORACLE_HOME property in BDD's configuration file.

You must also update some YARN-specific properties in your Hadoop cluster to ensure that each YARN worker node has access to sufficient resources. These are described in YARN setting changes.
