The session sub-folders are:
connection. Contains the mainframe application connection information, such as, host, port,
type, and language.
parameters. Contains the input fields and data you designate for the transaction.
metadata.
Contains the designated output expected from the transaction.
screens. Contains the information for the designated screens in the transaction.
As you build a transaction session, these subfolders become populated with the transaction
information.
You can now begin your emulation session, and capture the necessary screens and input and
output data, as explained in the following sections.
Capturing a Transaction
To capture an application transaction, navigate through the application and as you proceed:
Identify a screen that is necessary to the transaction. When the adapter executes the
request document at run time, it recognizes these designated screens.
If the screen contains required input fields (Parameters) that require values at run time,
define them to the transaction. The values will be provided in the request document at run
time.
If the screen contains output fields (Metadata) that you want returned at run time in the
response document, define them to the transaction.
Continue to navigate through the application and identify each screen and the input and
output fields that are necessary to the transaction.
Log off the mainframe application and save the emulation session.
The following procedures explain how to perform these tasks.
Note: If you need to include the contents or metadata of a table as input or output in your
transaction, see
How to Capture the Contents of a Table
on page 44.
