Use the Communications Server

The communications server controls the cross system communication service. When using cross system communication, client applications can:

Transmit client data across z/OS systems. For example, a client application can transmit commands and WTOs to copies of that same client application on other z/OS systems.
Share client files across z/OS systems. For example, a client application can transmit journal data among systems. By doing this, data from several systems can be maintained in one set of journals.
