Memory requirements

The amount of RAM your system requires depends on the amount of data you plan on processing.

The following table lists the minimum amounts of RAM 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
WebLogic	16GB This breaks down into 5GB for WebLogic Server and 11GB for the Transform Service. Note that installing the Transform Service on WebLogic nodes is recommended, but not required. If you decide to host it on a different type of node, verify that it has enough RAM.
Dgraph	5GB If you're planning on storing your databases on HDFS, your Dgraph nodes should have 5GB of RAM plus the amount required by HDFS and any other Hadoop components running on them. For more information, see Dgraph database requirements.
Data Processing (YARN cluster)	16GB Note that this is for the entire YARN cluster combined, not per node.

WebLogic

16GB

This breaks down into 5GB for WebLogic Server and 11GB for the Transform Service.

Note that installing the Transform Service on WebLogic nodes is recommended, but not required. If you decide to host it on a different type of node, verify that it has enough RAM.

Dgraph

5GB

If you're planning on storing your databases on HDFS, your Dgraph nodes should have 5GB of RAM plus the amount required by HDFS and any other Hadoop components running on them. For more information, see Dgraph database requirements.

Data Processing (YARN cluster)

16GB
