Multiple-domain Configuration

 

What Is a Multiple-domain Configuration

A multiple-domain configuration consists of two or more domains that communicate with each other. Each domain may be either a single-machine configuration or a multiple-machine configuration. Inter-domain communication is achieved through a highly asynchronous multitasking gateway that processes outgoing and incoming service requests to or from all domains. Multiple BEA Tuxedo domains can be connected, allowing clients in one domain transparent access to services physically located in remote domains. Each domain can share services and data, but is administered separately. 

The BEA Tuxedo system provides different types of gateways to accommodate various network transport protocols. Following are the different types of Domains gateways:

• The BEA Tuxedo Domains (TDomains) gateway provides interoperability between two or more BEA Tuxedo applications through a specially designed TP protocol that flows over network transport protocols such as TCP/IP.

• The BEA eLink for Mainframe-OSI TP gateways provides interoperability between BEA Tuxedo applications and other transaction processing applications that use the OSI TP standard. OSI TP is a protocol for distributed transaction processing defined by the International Standards Organization (ISO).

• The BEA eLink for Mainframe-SNA gateway provides interoperability between clients and servers in a BEA Tuxedo domain and clients and servers in an MVS/CICS or MVS/IMS environment in remote SNA domains. It also connects a local BEA Tuxedo domain to multiple SNA networks.

• The BEA eLink for Mainframe-TCP for CICS is a gateway connectivity feature that makes it possible for non-transactional tasks within BEA Tuxedo regions to access services provided by CICS application programs and vice-versa. It enables a BEA Tuxedo domain to communicate via the TCP/IP network transport protocol to a CICS environment.
  The BEA eLink for Mainframe-TCP for IMS is a gateway connectivity feature that provides transparent communications between client and server transactions in an IMS system and a BEA Tuxedo domain, a CICS system, or another IMS system.

• The TOP END Domain Gateway (TEDG) provides interoperability between BEA TOP END systems and BEA Tuxedo domains.
