DataWorks provides shared resource groups that you can use to create and run your nodes.

Shared resource groups are created and maintained by DataWorks. Take note of the following information:
  • You can run a maximum of 25 concurrent nodes on a shared resource group for Data Integration when the shared resource group is not in use. When you run nodes on a shared resource group, resources may be preempted. Therefore, the maximum number of nodes that can be concurrently run may be less than 25.
  • You cannot change the memory size of a shared resource group. Instead, you can change the number of concurrent nodes that can be run on the shared resource group.

    The following formula is used to calculate the memory size: Memory size = Number of concurrent nodes × 512 MB.
