Chapter 3: Building Production Objects

Creating DFC filters

Click DFC to create a filter that makes a DFC call from your production object. This allows you to avoid using ODL to make the DFC call. Use this filter to handle throughput issues.

Table 3-11: DFC filters

Name

Description

Func Field

Enter the name of the field to use or the field from the drop-down list.

Func DL

If you do not already have a function field, you can use a function datalink. If you do have a function field and enter a function datalink, the datalink is ignored. To create a function datalink, type it in the space provided or select one from the drop-down list.

Func Lit

If you do not have a function field or a function datalink, you can use a function literal. If you do have either one of the other functions, the function literal is ignored. To create a function literal, enter the name.

Flavor

This is the DFC function flavor. To increase or decrease the flavor, click the up or down arrows to the right of the field.

Timeout

This is how long the DFC call waits for a response before timing out. To increase or decrease the time-out, click the up or down arrows to the right of the field.

Fire and Forget

This function sends a DFC call, and does not wait for a response. When this option is selected, the timeout function is ignored.

Flow Control

This function appears only when the Fire and Forget option is selected. By enabling this function, you are telling the filter that on every “Nth” call, make a block call using the timeout function. Where “N” is the number of instances that can be spawned by your server.
