Display Active Initiators

To display active initiators

Select option 1 from the FTS : Initiator Supervision Menu and enter the Destination Name.
The FTS : Transmission Initiator Supervision panel appears.

FTS : Transmission Initiator Supervision Panel

This panel shows the current initiator set used to service transmission requests to the region whose link name is specified as the destination name. The status of the link to that destination also appears. You can exit the panel by pressing F3.

Note: If the link to the selected region is not activated, no initiator set is built, and the request is rejected.

This panel contains the following fields:

DESTINATION

Displays the link name of the remote region.

STATUS

Displays the current overall status of the link to the remote region:

PENDING-CONTACT: Indicates that the INMC link was started but contact is not established.
IN-CONTACT: Indicates that the INMC link is active and communications are available.
LOST-CONTACT: Indicates that the INMC link is broken.
NOT-COMPATIBLE: Indicates that the remote region is not configured with a compatible version of CA SOLVE:FTS or is not configured with CA SOLVE:FTS.

A secondary status also appears to the right of the overall link status. It indicates the transmission status.

* ACTIVE *: Indicates that transmissions are in progress.
* DRAINING *: Indicates that the FTS ENABLED field was set to N. Active transmissions proceed to completion, but no new transmissions are started or accepted from the remote region.
* IDLE *: Indicates that transmission is enabled, but no traffic is active or available to schedule against the available initiators.

TRANSMIT LIMIT

Displays the maximum number of concurrent transmissions that can occur to this destination, regardless of the number of active initiators.

Note: This field cannot be changed. It reflects the MAXIMUM CONCURRENT INBOUND FILES value set by the remote region.

FTS ENABLED

Specifies whether transmission is enabled:

Y

Indicates that transmission is active for this destination. Transmission requests are scheduled to this destination if any are available, and inbound transmissions are accepted.

N

Indicates that transmission is not active for this destination. No new requests are scheduled, and no inbound transmissions from the remote region are permitted.

Setting this field to N lets currently active transmission requests, both inbound and outbound, continue but no more are started. While there are existing transmissions, the status *DRAINING* appears to the right of this field.

Init

Lists the initiator numbers. CA SOLVE:FTS maintains a total of 16 initiators for each destination. The set of 16 is referred to as the initiator set.

Service Classes

Each initiator can service between one and 26 request classes (A to Z). Duplicate classes are not allowed. The order in which the classes are specified in this field, left to right, determines the order in which the initiator is allocated work. So, if a single initiator is defined, servicing classes ADCB, and three transmission requests for classes A, B, and C exist, they are executed in the order A C B.

Each of the 16 initiators defined as STARTED must be assigned at least one class.

Example: The following panel shows an initiator set with five initiators defined, servicing twelve different classes among 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 in the following panel are busy and a class A transmission request becomes available for execution, CA SOLVE:FTS would find 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 services class A in preference to any other class, and the request is assigned to initiator 3 for execution.

If a second class A request is issued while initiator 3 is still executing the first request, the second request would be assigned to initiator 2.

Started

Y indicates that the initiator is available for processing requests of its assigned classes. N indicates that the initiator is not available for processing requests.

Note: If this field is changed to N it prevents any further activity by that initiator. If the initiator is processing a request at the time, that request continues transmitting but no new requests are started when the current request ends.

Com

A value of 1, 2, 3, or N indicates the compression level to apply to transmissions performed by this initiator, where:

1: Indicates that blank string compression is required
2: Indicates that like string compression is performed.
3: Indicates bit level compaction. This is the default.
N: Suppresses compression on transmissions handled by the initiator.

Hi-pr

Y indicates that the initiator is allocated a higher transmission priority than normal priority (N) initiators. Transmissions executed under high priority initiators get preferential processing. But, the transmission of multiple concurrent requests to a particular destination causes all those requests to run more slowly than would be the case if only a single transmission was running.

Note: High priority should be used selectively—there is no advantage to making all initiators high priority.

CA SOLVE:FTS does not consider an initiator's priority setting when scheduling requests to initiators for execution. This means that if an initiator is always defined as high-priority so that requests of specific classes are always executed at high priority, the classes serviced by this initiator should not also be serviced by any other initiator; otherwise, there is no guarantee that requests intended to run at high priority are executed by the high-priority initiator.

In the example definition shown in the previous figure, initiator 1 is defined as high-priority and it services classes X, Y, and Z, which are unique to that initiator. This guarantees that class X, Y, and Z requests always execute at high priority.

Current Status

Specifies the current status. Valid values are:

*IDLE*: Indicates that the initiator is not processing any request, but is active and available for work of the nominated class.
(c) request-name: Indicates that the initiator is processing the transmission request, request-name, which is class c.
D--request-name: Indicates that the initiator is processing the transmission request name but has had its Started field set to N. The current request is continued, but no new request is started by that initiator. D indicates that the initiator is draining.

Note: To reverse the draining status, enter Y in the Started field.

P/S

If you want work to be split across available paths according to the INMC link definition as a whole, the field should be blank or contain a hyphen. If the designated session is not available, the work is serviced according to the INMC definition. The INMC link must have been defined with a transmission mode of preferential or rotate and backup. The value corresponds to the session number in the INMC link definition.

If you want to tie this initiator's work to a particular INMC session number, enter the number of the session.

Maximum Concurrent Inbound Files

Indicates the number of concurrent transmissions that this region is prepared to accept from the remote region. This value is reflected in the TRANSMIT LIMIT field at the remote region.

Setting this field to zero prevents the remote region from transmitting any data sets.

Setting this field to 16 permits the remote region to start up to 16 concurrent transmissions.

Setting the field to any intermediate value allows control over the inbound transmission count according to operational requirements.

Refresh

Specifies when the display is refreshed:

N

Updates the initiator set with any modifications when the Enter key is pressed and returns to the Initiator Supervision Menu.

Y

Refreshes the display each time the Enter key is pressed. This option enables continued displays of the initiator set status, for example, while waiting for all initiators to drain before terminating the link.

Any changes made to the panel are processed and the Initiator Set updated when the Enter key is next pressed.
