sandbox_subcluster

Sandboxes a subcluster in an Eon Mode database.

Sandboxes a subcluster in an Eon Mode database. All hosts in the subcluster must be up. When you sandbox a subcluster, its hosts immediately shut down and restart; the subcluster becomes sandboxed after the hosts start back up.

A sandbox can contain multiple subclusters, and subclusters in the sandbox can interact with each other. If you want to isolate subclusters, they must be in separate sandboxes.

Note

Subcluster sandboxing should be used for testing database changes or upgrades in a safe, isolated environment and should not be used for production subclusters. For example, you can create sandboxes and then upgrade Vertica in those sandboxes.

Syntax

vcluster sandbox_subcluster options

Required options

{ -c | --config } string: The path to the config file. If a configuration file is present in the default location (automatically generated by create_db), you do not need to specify this option.
Default: /opt/vertica/config/vertica_cluster.yaml

--sandbox string: The name of the sandbox. This string must conform to the format used for database names.
--subcluster string: The name of the subcluster to sandbox.

Options

--cert-file string: The absolute path to the certificate file. If you specify this option, you must also specify --key-file. You should only use --cert-file and --key-file if you have configured the Node Management Agent (NMA) to use custom certificates.

{ -h | --help }: Prints help text.

--ipv6: Whether the hosts use IPv6 addresses. Hostnames resolve to IPv4 by default.

--key-file string: Path to the key file. If you specify this option, you must also specify --cert-file. You should only use --cert-file and --key-file if you have configured the Node Management Agent (NMA) to use custom certificates.

{ -l | --log-path } string: The absolute path for debug logs.
Default: /opt/vertica/log/vcluster.log

{ -p | --password } string: The database password.
Default: "" (None)

--password-file string: The absolute path to a file containing the database password.
If you pass - (that is, --password-file -), the password is read from STDIN.

--read-password-from-prompt: Prompt the user to enter the password.

--verbose: Show the details of VCluster run in the console

Examples

To sandbox a subcluster sc1:

$ vcluster sandbox_subcluster --subcluster sc1 --sandbox sand \
  --hosts 192.0.2.0,192.0.2.1,192.0.2.2 --db-name test_db
