Local Execution (No Remote Tiers)

To use this example with no remote tiers (ie: as a standalone application):

Execute the Tier Configurator VL_SAM134 and make sure that you have this tier configuration:

System	Valid Connection Details Are Required	APPL Tier	DATA Tier	PRINT Tier	BATCH Tier
Default Client	No	System Itself	System Itself	System Itself	System Itself
Default iSeries	No	System Itself	System Itself	System Itself	System Itself

Close the Tier Configurator VL_SAM134.
Now execute form VL_SAM135 and test fetching the details of a few employees.
In this mode VL_SAM135 is running on your PC and accessing a DBMS that is locally accessible to your PC.

Thin Client Execution (Remote DATA Tier)

To use this example with a remote DATA tier (ie: as a classical Client/Server application)

Execute the Tier Configurator VL_SAM134 and make sure that you have this tier configuration:

System	Valid Connection Details Are Required	APPL Tier	DATA Tier	PRINT Tier	BATCH Tier
Default Client	No	System Itself	Default iSeries	System Itself	System Itself
Default iSeries	Yes	System Itself	System Itself	System Itself	System Itself

Close the Tier Configurator VL_SAM134.
Now execute form VL_SAM135 and test fetching the details of a few employees.
In this mode VL_SAM135 is running on your PC but accessing a DBMS that is defined on your iSeries server.

What does this example demonstrate ?

Some of the features that this form demonstrates are:

Some fundamental tier awareness techniques.
The isolation and abstraction of the physical system details away from this form.
A simple technique for switching this form between different modes of execution via external configuration.
