Using the BEA Tuxedo Domains Component

For the sample local Domain gateway configuration file, lapp.dom, only the required parameters are defined. Default settings are used for optional parameters.

The DM_LOCAL_DOMAIN section identifies the local domains and their associated gateway groups. This section has one entry, LAPP, and specifies the following parameters required for the domain gateway processes in that group:

GWGRP specifies the name of the gateway server group as specified in the application.
TYPE of TDOMAIN indicates that the local domain will be communicating with another BEA Tuxedo domain. This parameter indicates the protocol used by the gateways. Other options include SNA, OSI TP, TOP END Domain gateway, TCP for CICS, and TCP for IMS.
DOMAINID identifies the name of the domain gateway and must be unique across all domains.

The DM_REMOTE_DOMAINS section identifies the known set of remote domains and their characteristics. This section has one entry (RAPP). TYPE is used to classify the type of domains. DOMAINSID is a unique domain identifier.

The DM_TDOMAIN section defines the addressing information required by the BEA Tuxedo Domains component. Following are entries in the section for each local and remote domain specified in this configuration file:

NWADDR specifies either the network address at which connections will be accepted from other BEA Tuxedo domains (local domain entry), or the network address at which connections to other BEA Tuxedo domains will be made (remote domain entry).

The DM_LOCAL_SERVICES section provides information about the services that are exported. This section of our sample file has no entries because no services are being exported.

The DM_REMOTE_SERVICES section provides information about the services that are imported. The TOUPPER service is imported so that it can be accessed by clients in the local domain.
