I am using temporal 27 ,when i try to register a global domain, its failing unable to register domain

Version temporal 27

Request sent :

RegisterNamespaceRequest request = RegisterNamespaceRequest.newBuilder().setName(ns)  
.setEmitMetric(true)  
.setHistoryArchivalState(ArchivalState.ARCHIVAL\_STATE\_ENABLED)  
.setIsGlobalNamespace(true)  
.setOwnerEmail(“[me@myself.me](mailto:me@myself.me)”)  
.setWorkflowExecutionRetentionPeriodDays(5).build();  
int retryCount = 0;

```
				// in while loop i attempt registration with this call ->service.blockingStub().registerNamespace(request);

```

Response :  
io.grpc.StatusRuntimeException: INVALID\_ARGUMENT: Cannot register global namespace when not enabled  
at io.grpc.stub.ClientCalls.toStatusRuntimeException(ClientCalls.java:244)  
at io.grpc.stub.ClientCalls.getUnchecked(ClientCalls.java:225)  
at io.grpc.stub.ClientCalls.blockingUnaryCall(ClientCalls.java:142)  
at io.temporal.api.workflowservice.v1.WorkflowServiceGrpc$WorkflowServiceBlockingStub.registerNamespace(WorkflowServiceGrpc.java:2554)…

If i set the isGlobalDomain to false i am able to register succesfully.

How should i enable global domain?

Hey @madhu,  
We have renamed the `domain` concept as `namespace` in Temporal. So I’m going to assume you meant GlobalNamespace in rest of the response. Based on the error you are seeing looks like `GlobalNamespace` feature is not turned on for the cluster. You need to configure [clusterMetadata](https://docs.temporal.io/docs/configuring-temporal-server#clustermetadata) section of the config to enable cross datacenter with namespace replication. Here is an example:

ClusterMetadata for Cluster A

```auto
clusterMetadata:
  enableGlobalNamespace: true
  replicationConsumer:
    type: kafka
  failoverVersionIncrement: 10
  masterClusterName: "ClusterA"
  currentClusterName: "ClusterA"
  clusterInformation:
    ClusterA:
      enabled: true
      initialFailoverVersion: 1
      rpcName: "frontend"
      rpcAddress: "localhost:7933"
    ClusterB:
      enabled: true
      initialFailoverVersion: 2
      rpcName: "frontend"
      rpcAddress: "localhost:8933"

```

Configure Kafka for replication on Cluster A:

```auto
kafka:
  clusters:
    test:
      brokers:
        - 127.0.0.1:9092
  topics:
    ClusterA:
      cluster: test
    ClusterA-dlq:
      cluster: test
    ClusterB:
      cluster: test
    ClusterB-dlq:
      cluster: test
  temporal-cluster-topics:
    ClusterA:
      topic: ClusterA
      dlq-topic: ClusterA-dlq
    ClusterB:
      topic: ClusterB
      dlq-topic: ClusterB-dlq

```

And finally make sure publicClient section is also setup correctly in case of call forwarding from one cluster to another:

```auto
publicClient:
  hostPort: "localhost:7933"

```

Here is how the config should look like of `ClusterB`:

```auto
clusterMetadata:
  enableGlobalNamespace: true
  replicationConsumer:
    type: kafka
  failoverVersionIncrement: 10
  masterClusterName: "ClusterA"
  currentClusterName: "ClusterB"
  clusterInformation:
    ClusterA:
      enabled: true
      initialFailoverVersion: 1
      rpcName: "frontend"
      rpcAddress: "localhost:7933"
    ClusterB:
      enabled: true
      initialFailoverVersion: 2
      rpcName: "frontend"
      rpcAddress: "localhost:8933"

kafka:
  clusters:
    test:
      brokers:
        - 127.0.0.1:9092
  topics:
    ClusterA:
      cluster: test
    ClusterA-dlq:
      cluster: test
    ClusterB:
      cluster: test
    ClusterB-dlq:
      cluster: test
  temporal-cluster-topics:
    ClusterA:
      topic: ClusterA
      dlq-topic: ClusterA-dlq
    ClusterB:
      topic: ClusterB
      dlq-topic: ClusterB-dlq

publicClient:
  hostPort: "localhost:8933"

```

The documentation on setting up Temporal with CrossDC setup is very thin at the moment but we will provide more content around it after our V1 release.

Thanks @samar i was under impression that i can create a global namespace by just setting the global = true while creating namespace 😃

Thanks for clarifying that the server got to be configured to accept global namespace registration.

Hey @madhu,  
Global namespace requires running Temporal with CrossDC setup.

after the Kafa replication is deprecated, is this configuration still valid?

if not whats the alternative config to be used?

not sure how this is related to [Configure the Temporal Server | Temporal documentation](https://docs.temporal.io/docs/server/configuration#global)

and how is this related to

services:  
frontend:  
rpc:  
grpcPort: 8233  
**membershipPort: 8933**  
bindOnLocalHost: true  
metrics:  
statsd:  
hostPort: “127.0.0.1:8125”  
prefix: “temporal\_standby”

@madhu if you are talking about `clusterMetadata` config then it is still valid. The only difference is `replicationConsumer` is gone as all Kafka related replication code now removed and we only support `rpc`.  
`Global` section in the config has nothing to do with `Cross DC Setup`. This is to configure services which are generically applicable to all parts of the system, like `membership`, `pprof handler`, `tls`, etc.  
Same goes for the `services` section. Which has the config settings for individual roles within Temporal.

Thanks @smar, i looked thorough he samples and found that these are still valid.
