Authority
You must have root authority and must run this command on the InfoSphere Streams resource that you want to remove.
Description
Unlike the streamtool rmdomainhost command, this command can remove a resource from the domain even when the domain controller service is stopped on that resource. It also differs in that it removes the domain controller service from the list of Linux system services on the resource.
- It is the last resource in the domain. Instead, you must use the streamtool rmdomain command.
- The resource is allocated to an instance in the domain and the instance is started. You must stop the instance before you remove a resource. For more information, see the streamtool stopinstance command.
- There are InfoSphere Streams services other than the domain controller service that are running on the resource. You must stop or quiesce the resource before you remove it. For more information, see the streamtool quiesceresource and streamtool stopdomainhost commands.
Options and arguments
- -d, --domain-id did
Specifies the domain identifier.
If you do not specify this option, InfoSphere 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.
- --force
Specifies to force a cleanup of the system service. The command tries to unregister the host from the domain only if the ZooKeeper connection is active and the domain exists. Use this option only if the request to unregister fails. This option ignores certain error conditions.
- -h, --help
Specifies to show the command syntax.
- --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
- -v,--verbose level
Specifies to provide more detailed command output. The vebosity level can be from 0 to 3 where 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, InfoSphere Streams tries to use:- The value from the STREAMS_ZKCONNECT environment variable
- A ZooKeeper connection string that is derived from cached information about the current domain.
