Batch Response Think Time Companion

The Batch Response Think Time companion varies the think scale so that a virtual service model sends a defined number of responses at specified times.

This companion lets you batch responses for a virtual service model. You can specify a schedule for sending responses. For example, you can send 100 responses every day at 8:15. The requests can arrive at any time, but VSE only responds at 8:15. If there are fewer than 100 pending responses, VSE sends all the responses. If there are more than 100 pending responses, VSE sends 100 responses and saves the rest until the next batch.

VSE only responds to incoming requests; it does not generate unsolicited responses. If VSE receives 12 requests, it sends 12 responses, even if the Quantity is greater than 12.

This companion is useful only for the SAP transport protocol.

Enter the following parameters in the companion editor:

Enabled

Specifies whether to enable the companion.

Time

Defines when to send the responses.

Values: 00:00 to 23:59.

Quantity

Defines the maximum number of responses to send.

Click Add, Up, Down, and Delete to add, move, and delete rows in the Response Schedule table.

Repeat daily

Specifies whether to send responses each day.

Send all at once

Specifies how to distribute the responses.

Values:

• Selected: Sends the responses all at once or as the requests arrive for the specified interval until the size limit is reached.
• Cleared: Spreads the responses evenly between the time for the current batch until the time for the next batch or the scheduled end time.

Schedule End Time

If the Send all at once check box is cleared, this field defines the end time for the last-scheduled time in the Response Schedule table.

Values: 00:00 to 23:59.

Limits: The value must be later than the last-scheduled time in the Response Schedule table.

Example:

Assume that the Response Schedule table contains two entries:

• The first entry has the values 08:00 and 10.
• The second entry has the values 08:10 and 10.

Also assume that the Send all at once check box is cleared and the Schedule End Time field is set to 08:15.

When you deploy the virtual service model, the results of this configuration are:

• One response each minute between 08:00 and 08:10
• One response every 30 seconds between 08:10 and 08:15.

These results assume that the service receives enough requests with matching responses during those periods.
