5.2.2 Direct User ID Mapping

Direct user ID mapping enables the direct mapping of an ATMI user ID to an identical host user ID. This eliminates the need to use the dmadmin commands, as with ATMI-to-host user ID mapping. When this feature is used, any user ID mappings in the BDMCONFIG file are bypassed. To enable this feature, specify a command-line parameter with the GWSNAX command when starting the Oracle Tuxedo Mainframe Adapter for SNA Gateway. Refer to the Bypassing User ID Mapping section.

Note:

When direct user ID mapping is used, modification or elimination of any BDMCONFIG file mapping entries is not necessary.

With direct user ID mapping, the user IDs in the ATMI and host environments must be identical as shown in following figure. When the ATMI local domain initiates a request, the ATMI user ID is applied to the requested host service. When the host initiates a request, the host user ID is applied to the requested ATMI service.

Note:

Identical user IDs must exist in the local domain and in the host domain for direct user ID mapping to be used. With direct mapping, only security level IDENTIFY can be supported.
