SNA Server DLC Outage Codes Should be Logged in Hex.

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: 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.
