SYMPTOMS
When an SNA Server connection failure occurs, SNA Server logs Event 23 in
the Windows NT application event log and indicates the error code returned
by the SNA Server link service in the Qualifier field. For example:
Event ID: 23
Source: SNA Server
Description: Connection <connection> using Link Service <link> failed
Qualifier = 00xx
The "xx" value in the Qualifier field indicates the "outage code", which is
logged in hex format, such as "00AE". The meaning of these hex-formatted
outage codes are documented in the SNA Server Reference Guide under Event
23, as well as in the SNA Server Device Interface Specification in Section
3.4.
When enabling SNA Server Data Link Control (DLC) tracing using the SNATRACE
program (on either the SNA Server service, or a link service), the
<snaroot>\traces\NODEMSG?.TRC message trace file will also log the outage
code. However, the outage code logged in the DLC message trace is logged in
decimal, which can cause confusion. For example:
| DLC ---------------------------------------------- 14:15:37.37
| DLC 05160000->01020100 DLCST OUTG
| DLC Outage:174 UPTYPE:0 UPCNTR:0 COUNT:0
| DLC
| DLC ---- Header at address 00CF478C, 0 elements ----
| DLC 18110000 00000000 00000000 0100C600 <..............F.>
In the above case, the outage code of 174 decimal is equivalent to 0xAE
hex.
