Target Requirements

Key Requirements

O/S User / Privileges
  1. Delphix O/S user which is identical to the cassandra software installer O/S user. Script to create Delphix O/S user: createDelphixOSUser.sh
  2. Delphix O/S user must have read and execute privileges on:
    • Cassandra Install Path: Location where software binaries are installed.
  3. The Cassandra installation on the target environment must have the same version as the staging environment.
    • In case of multi-node VDB setup on different target hosts:
      • The delphix o/s user configuration should be identical on all additional hosts, the uid & gid should be similar. Cassandra binaries should be installed on identical locations. Example:
      • If on primary node, the Cassandra binary is available at /u02/cassandra/dse-node/bin/dse
      • On all additional nodes, the binary of same version should be present at same location (i.e. /u02/cassandra/dse-node/bin/dse)
  4. There must be a directory on the target environment where you can install the Delphix Plugin. This directory should have 2GB of available storage.
  5. Empty folder on host to mount nfs filesystem. This is just and empty folder with no space requirements and act as base folder for nfs mounts.
  6. Please ensure any login banners similar to the one in the image below must be disabled on the target host. Screenshot
  7. The Delphix OS user account requires privilege elevation specifications. Here is an example specification for the sudo privileges for mount, umount, ip on the staging host. 
    Defaults:delphix !requiretty
delphix ALL=NOPASSWD:/bin/mount,/bin/umount,/sbin/ip
  8. Install the OS utilities on the target host to ensuring smooth execution of automated processes.
    • expect : The utility plays a crucial role in automating interactive processes on the target host.
