   Setting Up a BEA Tuxedo Application

The MASTER machine controls the booting and administration of the entire application. You must specify a MASTER machine for every application by setting the MASTER parameter. The value of MASTER is the Logical Machine Identifier (LMID) for the appropriate computer. The LMID, in turn, is defined as an alphanumeric string, chosen by the administrator, that is assigned to the LMID parameter in the MACHINES section. Therefore, for example, if the value of the LMID parameter is SITE1, then the value of MASTER must also be SITE1.

If you want to be able to bring down the MASTER machine without shutting down the application, you must be able to migrate the MASTER. To enable migration, you must specify two values for LMID: the primary MASTER and the backup MASTER.

The MASTER parameter has the following characteristics:

• It is required and it controls booting and administration.

• Two LMIDs are required for migration to back up the master machine.

• In the sample RESOURCES section, the master site is SITE1; the backup site is SITE2.
