Requirements for staging and target Cassandra environments

Requirements

Staging Environment

Target Environment

The Delphix O/S user must be identical to the Cassandra software installer O/S user. Use the script createDelphixOSUser.sh to create the Delphix O/S user.

The Delphix O/S user must have read and execute privileges on the Cassandra install path, where software binaries are installed.

The Cassandra installation on the staging and target environment must have the same version as the source environment.

The Delphix O/S user configuration must be identical on all additional hosts, with the same UID and GID.

NOTE: This needs to be done for multi-node VDB setups on different target hosts.

Cassandra binaries should be installed in identical locations. For example:

• If the primary node has the Cassandra binary at (/u02/cassandra/dse-node/bin/dse).

• All additional nodes must have the same version binary at the same location (/u02/cassandra/dse-node/bin/dse).

NOTE: This needs to be done for multi-node VDB setups on different target hosts.

Y

There must be a directory on the target environment with 2GB of available storage to install the Delphix Plugin.

An empty folder on the host is required to mount the NFS filesystem. This folder does not require additional space and serves as the base for NFS mounts.

Disable any login banners similar to the one shown in the provided image on the target host.

The Delphix OS user account requires specific sudo privileges. Below is an example configuration for the sudo privileges for mount, umount, and IP commands on the staging host:

Defaults:delphix !requiretty

delphix ALL=NOPASSWD:/bin/mount,/bin/umount,/sbin/ip

Ensure the expect utility is installed on the staging and target host. Cassandra Connector runs password sensitive commands by making use of expect utility.
