SNAX/HLS Configuration and Control Manual

Objects and Attributes

RESPONSE-TYPE
This PROFILE attribute has the possible values 1, 2, or 3. The default value is 1.
RESPONSE-TYPE specifies the initial response type that is requested. The valid values
are 1, 2 or 3, corresponding to DR1, DR2, or DR1&DR2 respectively. This value can be
modified by the application program.
The choice of DR values used on any given message can imply certain side effects,
especially if the partner is IMS or a similar product. Consult the product specification
carefully.
SINGLE-FMH
This PROFILE attribute has the value type yesno . The default value is NO.
SINGLE-FMH specifies whether FM headers can be continued. This is important for
SNAX/HLS only when data translation is selected; FM headers are never translated.
The SNA use of FM headers assumes that the first two bytes of each FM header has the
format shown in Table 4-3.
Table 4-3. FM Header Format
Byte Bit Content Meaning
0 Length Length of header including the length byte. Thus, zero is an illegal value.
1 0 FMHC FMH concatenation.
0 No FMH follows this one
1 Another FMH follows this one
1 1-7 Type FM header type.
Not all FM headers can validly be followed by others; the rules are specific to the LU
type and the application. In addition, not all applications treat the FMHC indicator
uniformly. CICS talking to an IBM 3600 is one such example. If the protocol is such
where the ninth bit of the FM header (FMHC above) should not be interpreted as a
continuation bit, the SINGLE-FMH indicator should be set to TRUE.
For further information about FM headers, see Systems Network Architecture —Sessions
Between Logical Units, (IBM publication GC20-1868).
