1-12 118474—TRANSFER Release D30 Documentation Supplement
TRANSFER D30 Documentation Supplement
To allow adjustment of the priority of the incoming message, three new parameters are 
added to the X400-IMPORTER server class:
PARAM PRIORITYURGENT (Default 125) 
PARAM PRIORITYNORMAL (Default 75) 
PARAM PRIORITYLOW (Default 25)
PRIORITYURGENT must be greater than PRIORITYNORMAL, and 
PRIORITYNORMAL must be greater than PRIORITYLOW. It must also be less than or 
equal to the maximum priority set in the _X400_ depot's profile, which defaults to 150.
Checks are performed at server start-up to verify that the new PARAM values conform; 
otherwise, the server outputs an error message and stops.
If only the param PRIORITYNORMAL is set, the X400-IMPORTER will add 50 to this 
value to obtain the value for PRIORITYURGENT; it will subtract 50 for the 
PRIORITYLOW value.
As an example, to get TRANSFER's default settings of 50, 100, and 150, the param 
PRIORITYNORMAL should be set as follows:
PARAM PRIORITYNORMAL "100"
The X400-Exporter recognizes two new PARAMs indicating which X.400 priority to 
use for Transfer priorities.
PARAM MAXPRINORMAL (Default 124) 
PARAM MAXPRILOW (Default 74)
For TRANSFER messages with priority > MAXPRINORMAL, the Exporter sets the 
X.400 message to URGENT. For TRANSFER messages <= MAXPRILOW, the X.400 
message is marked LOW, and for priorities > MAXPRILOW and <= 
MAXPRINORMAL the X.400 message is NORMAL.
The value of MAXPRINORMAL must be greater than MAXPRILOW. If only the 
PARAM MAXPRINORMAL is given, the value for MAXPRILOW is 
MAXPRINORMAL - 50. If it is a negative number, then MAXPRILOW = 
MAXPRINORMAL/2. 
X.400 Probes 
The TRANSFER X400 Gateway supports X.400 probes, both incoming and outgoing.
Outgoing Probes Generated by a TRANSFER Application
To generate a probe from TRANSFER that reports back on an X.400 O/R Name, the 
application can use the existing ALTER-ITEM-DESCR-XXX UOWs. The PROBE-
MSG field of the DELIV-CONTROL-FLAGS, when set to “Y”, signals that this item is 
a probe. (Prior to this release, TRANSFER required that this field be set to N.)
To create a probe message:
1. Use CREATE-ITEM, set the item type to 109 (ORIGINAL) and set the IS-PKG-
HDR flag to “Y.”
