Rename the Domain
You can change the domain name and update nodes to reference the updated domain name.
If the Informatica domain uses Kerberos authentication, all service and node SPNs have the same Kerberos realm name. After you change the Informatica domain name, you must generate SPNs and keytab files with the new Informatica domain name.
To rename the domain, complete the following tasks:
1. If the domain contains a PowerCenter global repository, you must unregister all local repositories from the global repository.
2. Shut down the domain. Shut down the domain through the Administrator tool, ensuring that all nodes are shut down.
3. Back up the domain with the infasetup BackupDomain command.
4. Back up the sitekey and keytab files. By default, the files are in the following location:
<Informatica installation directory>/isp/config/keys
5. Update the domain and nodes.
To update the domain name, run the infasetup updateDomainName command from any gateway node.
Run the updateGatewayNode and updateWorkerNode commands with the updated domain name for all the gateway and worker nodes.
6. On PowerCenter, register the local repository with a connected global repository with the updated domain name with the pmrep Register command.
7. You can create SPN and keytab files with the updated domain name for Kerberos authentication. Copy the keytab files in the keys directory. You can continue to use the older site key file. If you need to regenerate the site key when it is missing or corrupted, you must provide the older domain name.
8. Optionally, you can run the License Management Report in the Administrator tool to review the updated domain name.
9. You must configure the Informatica clients to use the updated domain name.
