Transfer Request is Initiated

The transfer request is normally initiated from the PC environment but can be initiated from the mainframe, depending on the file transfer program used. From the mainframe, the transfer request can be initiated in either of two modes:

• Immediate mode

  By a single request, all the currently available packets are transferred. This is a manual request issued by the PC user.

• Polling mode

  By repetitive requests, the packets that are (or become) available within the scheduled time period are transferred. Scheduling specific times allows unattended report transfer overnight.

Polling Mode is the recommended mode, since transfer may be scheduled for times when the reports are likely to be ready on the mainframe. Furthermore, the demand on mainframe resources can be reduced by scheduling report transfer at non-peak times.
