When an INMC link becomes active for the first time, a set of 16 transmission initiators reserved for the transmission of files is built.
Each initiator is assigned one or more transmission classes and has a status of STOPPED or STARTED. Each file transmission operation to the other CA SOLVE:FTS region uses one initiator for the duration of the transmission, so the number of concurrent transmissions that can take place is limited to the number of defined and started initiators.
File transmissions are assigned a transmission class (alphabetic, A to Z) that determines which initiators the transmission may use. The meaning of these classes is similar to that of operating system job classes—that is, the class of a transmission governs the choice of initiators that are able to service that transmission. The installation may therefore separate testing and production, or high and low priority transmissions by class.
You can use the default settings for a group of initiators for a particular definition and CA SOLVE:FTS builds an initiator set configured as follows:
1 : Services classes A - Z in order. Initial status is `STARTED'.
2-15 : Service class A only. Initial status is 'STOPPED'.
If this default set of initiators is sufficient, you need take no further action. If, however, you want to set up a different set of initiators for this particular destination, you must define the initiator set.
When you start the INMC link between the two regions, if an initiator is defined, it is used; otherwise, the default settings are used.
To define custom initiators
The FTS : Administration Menu appears.
The FTS : Transmission Initiator Definition panel appears.
Specifies the destination. This is the INMC link name associated with the other end of the transmission request.
Specifies whether FTS activity is allowed automatically when the INMC link to this system becomes active.
Specifies the maximum number of transmissions this system can receive at any one time from the destination system.
Specifies the FTS classes serviced by this initiator.
Specifies the initial status of the initiator.
Specifies the compression level.
Specifies the priority of this initiator in relation to all other initiators for this destination.
Specifies the preferred INMC session number to use for this initiator.
Press F4 (Save)
The definition is saved.
The following example shows an initiator set with five initiators defined, servicing 12 different classes between them.

When multiple initiators are defined and a request is available for execution with a transmission class that is serviced by more than one (available) initiator, the request is scheduled under the initiator that has the highest preference for that class.
For example, if none of the five initiators shown are busy and a Class A transmission request is available for execution, CA SOLVE:FTS finds that initiators 2 and 3 both service class A, but that initiator 2 accepts class A requests only if no class C or F requests are available. Initiator 3, however, services class A in preference to any other class. In this case, CA SOLVE:FTS assigns the request to initiator 3 for execution. A second class A request issued while initiator 3 is executing the first request would be allocated to initiator 2.
