VTCPD Application Programming

P0602483 Ver: 03.41 Page 73

If the applications set the message ID, the applications must ensure that no two

requests use the same message ID — in this configuration, VTCPD does not verify the

message ID. If two outstanding requests use the same message ID, the results are

unpredictable.

VTCPD can be started when some or all of the host specifications are unavailable.

However, applications can not use these host connections until additional information

is associated with the links. An administrative application can be used to establish the

remaining host information (see Establishing or Changing the Host Specifications

on page 79.)

The applications can be set up to reserve a connection and then solicit data from the

host (see Soliciting Host Data on page 73.), or to wait for a host to send data (see Host

Driven Applications on page 76.)

For configurations that support multiple message formats or systems that use a backup

VTCPD, the application must be set to communicate with the appropriate instance of

VTCPD (see Configurations That Require Multiple VTCPD on page 91.)

Soliciting Host Data

The application can be set to solicit host data (see Application-Defined Mode on page

29.)
