The command in the installation step installs R only on the queen node.
  1. To sync R across all workers in the cluster:
    1. On systems running a supported version of the Aster Database (AD 6.20.04 and later) or a supported version of the Aster Execution Engine (for example, AX 7.00.01), issue this command: ncli apm administer R --synchronize
    2. On systems running a supported version of the Aster Database (AD 6.20.03 and earlier), issue these commands:

      ncli system softrestart

      ncli system activate

  2. To confirm that R is successfully installed on all worker nodes in the cluster, run this command on the queen node: ncli apm show R --localconfig

    The command should run without any errors, and the output should show the R version installed on the queen node and the worker nodes. All nodes should have the same R version.

    The R and R packages on Aster are installed in the /opt/aster/third-party/R directory on the queen and worker nodes in the Aster Database cluster.
