Main design tasks in the Server Dialog and Server editors
Creating a user buffer
In the Server Dialog, you can define a user buffer to complement
the technical buffer.
Creating a server buffer
You can define a server buffer in a Server Dialog or a
Business Component.
Calling external resources in a Business Component
In a Business Component, you can specify services associated
with a Logical View. To implement a service, you must declare the
Logical View containing the service request issued by the client component.
Then, you must perform the access to the external resources to check
data consistency and the data items that must be sent to the client
component. The access must be specified in the -CS Lines tab
of the Business Component.
Error messages in Servers
A Business Component implements the services that are associated
with a Logical View. As it runs the service, it can detect errors.
In this case, it must send the error information in its reply message
to the client so that the client can take the appropriate action.
Modifying the internal resources of a batch or online program
The internal resources of a batch or online program are
its work or linkage areas. You can replace their automatically generated
descriptions by calling Data Structures or Data Elements in the work
and linkage areas. To do so, you specify micropatterns directly in
the COBOL code of the generated instance.
Adding or modifying Macro calls
When you call a Macro, its lines are inserted in a batch
or online program. You can then use standard sequences of specific
code several times in the same program or in different programs. To
call a Macro, you must select it in the -CP Lines tab.
If it is parameterized, you must assign values to its parameters.
