streamtool startdomainhost

Usage

startdomainhost [-d,--domain-id <did>] [--unregistered [--ipaddress <ipaddress>] [--tags <tag>,...] [-U,--User <user>]] [-h,--help] [--trace <level>] [-v,--verbose <level>] [--zkconnect {<host>:<port>},... | --embeddedzk]

The streamtool startdomainhost command starts the domain controller service on an Streams resource.

Authority

You must have root authority and you must run the command for a registered system service on the Streams resource that you want to start.

To run the command with the --unregistered option to set up the domain host as an unregistered system service, you do not need root authority. However, the domain must exist and be started, and you must be the same user who started the domain.

Description

Use the startdomainhost command to start the domain controller service as a registered Linux system service. To configure the domain controller service to run as a system service, run the streamtool registerdomainhost command.

Options

-d,--domain-id <did>
Specifies the domain identifier.

If you do not specify this option, Streams uses the domain name that is set in the STREAMS_DOMAIN_ID environment variable. By default, that domain name is StreamsDomain. If you are using the interactive streamtool interface, it uses the name of the active domain for the current streamtool session or else it prompts you for the domain name.

The active domain for the current streamtool session is set every time that you successfully run a streamtool command with a -d or --domain-id option. Alternatively, you can run the streamtool domain command in the interactive interface.

--embeddedzk

Specifies to use the embedded copy of ZooKeeper. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify either this option or the --zkconnect option, Streams uses the ZooKeeper connection that is associated with the active domain or the domain that is specified in the --domain-id option. Streams determines which connection maps to the domain by using cached information about the domains. In this scenario, if the domain identifier is not unique in the Streams configuration cache, the command fails.

-h,--help
Specifies to show the command syntax.
--ipaddress <ipaddress>
Specifies the system service IP address.
--tags <tag>
Specifies a comma-separated list of tags, which the command assigns to the host.
--trace <level>
Specifies the trace setting. The following valid levels are listed in order of increasing verbosity, which is to say that the first level in the list generates the least amount of information:
  • off
  • error
  • warn
  • info
  • debug
  • trace
The default value is off.
-U,--User <user>
Specifies an Streams user ID that has authority to run the command.
--unregistered
Specifies to start the domain controller service as an unregistered service. The domain must exist and be started if you run the command as a non-root user.
-v,--verbose <level>
Specifies to provide more detailed command output. The verbosity level can be 0-3, where 0 disables detailed reporting and each increment provides more detailed output.
--zkconnect <{<host>:<port>},...>

The name of one or more host and port pairs that specify the configured ZooKeeper servers. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify this option, Streams tries to use:

  1. The --embeddedzk option
  2. The value from the STREAMS_ZKCONNECT environment variable
  3. A ZooKeeper connection string that is derived from cached information about the current domain.
