From SAP ESP Studio, projects can be deployed to run on local or remote clusters. ESP Studio manages a special “local cluster” making it easy for a developer to work on their local machine by automating the start/stop of the cluster automatically. This local cluster is typically used by a single developer, and is not accessible to other machines by default.
Occasionally, a colleague may want to access a project you are developing on your Studio-local cluster, or you may want to test access of an ESP client application on a remote machine to your local project. Although this isn’t possible with the out-of-the-box configuration, Studio’s local cluster configuration can easily be changed to support remote access.
The cluster configuration files used to start Studio’s local cluster are located in the %ESP_HOME/studio/clustercfg directory. In that directory is a localnode.xml file and in that files is a ESP_HOSTNAME macro (see below). Upon installation, this macro is set to localhost. To make Studio’s local projects accessible to other machines, replace localhost with a hostname or IP address. The hostname may need to be fully-qualified depending on your network configuration. Once this change is made, projects you start on Studio’s local cluster will be accessible to any machines on the network that: a) can access your machine on the network, and b) can provide the credentials you specified upon startup of the cluster.

If multiple developers will be interacting with a project you will want to consider starting a cluster outside of ESP Studio. Please see Starting a Node or Cluster for information on starting a cluster and Connecting to a Remote Cluster for information on accessing an external cluster from ESP Studio.
