To Execute this Example
To use this example with no remote tiers (ie: as a standalone application):
To use this example with a remote DATA tier (ie: as a classical Client/Server application)
Some of the features that this form demonstrates are:
| Data Tier Awareness | The Things that Make Up this Example |
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.
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.
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.
