Activity Reporting

Messages are logged and sent to OCS Mode screens with the appropriate profile (PROFILE FTSMSG=YES,UNSOL=Y), to record start, stop, or restart of all transmission requests, including details of errors encountered (for failed requests) and statistical information (for successfully completed requests).

In addition, you can display requests that terminate because of errors through the Transmission Supervision function. This function identifies the cause of failure.

You must reset failed requests after the cause of failure is corrected and before the region attempts to reschedule them for restart. To reset failed requests, use the Transmission Supervision panels or the FTSMOD command.

Note: Transmissions that are interrupted because of a link outage are restarted automatically on restoration of the link unless the automatic restart option has been suppressed.

A specific error code is associated with each failed request. For detailed explanations of the possible causes of these codes, select option CC from the FTS : Transmission Supervision Menu or enter the Q (Query) action against a request on the Transmission Supervision List.

Initiators and Network Routing

INMC links can take advantage of multiple physical routes through the network to maximize the use of available bandwidth and to minimize disruption of operations through the loss of one or more network paths. In some cases, however, it may be desirable to route certain bulk data traffic across one specific route—for example, certain high priority transmissions may be required to traverse a dedicated high speed link.

Each initiator can be assigned to a preferred session in an INMC session group. If this option is exercised, all transmissions of the initiator are directed across one specific session (provided the session is open).

Note: For more information about INMC link characteristics, see the Reference Guide.

Initiators and Data Compression

The data transmitted as part of a file transmission operation is compressed according to one of three supported compression algorithms:

Bit-orientated data compaction
Compression of strings of blank characters
Compression of strings of any character

For each initiator, you can select the type of compression or suppress compression completely.

By default, bit-orientated data compaction is used.
