5.2.3.2 Setting DMCONFIG File Security Parameters

Three sections in the DMCONFIG file contain parameters affecting Oracle Tuxedo Mainframe Adapter for SNA control of access to the ATMI local domain:

  • DM_LOCAL_DOMAINS section contains a SECURITY parameter which specifies the type of security enforced for the ATMI local domain.
  • DM_SNALINKS section contains a SECURITY parameter that records the security in effect for the host system.
  • DM_ACCESS_CONTROL section contains local access control lists used by the ATMI local domain to associate local resources with host systems permitted to have access to them.

Caution:

Do not delete the DMCONFIG binary file before running the dmloadcf command. Tables of remote users, remote passwords, and remote mappings are stored in this file. If deleted, all security information must be re-entered.
