Command-Driven Execution Model

The Mercator Command Server provides a command-driven capability for the

execution of integration maps. This model is normally associated with batch-

driven, one-off integration processes. A variety of methods exist for executing

maps in command mode such as:

♦ Execution and utility commands typed at the command prompt

♦ Execution commands invoked at the command prompt via a command

parameter file

♦ From the Mercator Command Server, which provides a GUI enabling you to

load and run maps, and also override map settings (Windows platform only)

♦ Execution commands defined in a batch file or shell script

♦ Execution commands defined in a scheduling program

As mentioned earlier, by default, the map’s execution settings (such as MapAudit

and WorkSpace) are compiled into the runtime object. In all modes of execution,

it is possible to override almost all of these settings at runtime. In the case of

Command Server invocation, the overrides are supplied as parameters on the

command line. For example:

/mercator/bin/mercator /mercator/maps/mymap.hp
