Updating a Teracloud® Streams Version 7.2.0 Non-Production Edition license

Use this procedure to update a Teracloud® Streams Version 7.2.0 Non-Production Edition license to the Teracloud® Streams Version 7.2.0 product license.

Before you begin

To update the Version 7.2 license, you must be the installation owner or have root authority.

Procedure

To update the Non-Production Edition on the current resource only, enter the following commands:

  unset STREAMS_ZKCONNECT
  source product-installation-root-directory/7.2.0.0/bin/streamsprofile.sh
  streamtool updatelicense

To update the Non-Production Edition on all the resources in one or more domains, enter the following commands:
```
  source product-installation-root-directory/7.2.0.0/bin/streamsprofile.sh
  streamtool updatelicense --zkconnect host:port
```
The --zkconnect option specifies the name of one or more host and port pairs for the configured external ZooKeeper ensemble. If you specify multiple host and port pairs, separate each pair with a comma. This value is the external ZooKeeper connection string. To obtain this value, you can use the streamtool getzk command.
This command updates the installation on the current resource and on all resources in the domains that are managed by the specified ZooKeeper server. If a domain is not active, the installation is updated when the domain is started.
