Inetinfo.exe Ends with MTS Event 4097 Using Microsoft ODBC for DB2 (247375)
The information in this article applies to:
- Microsoft SNA Server 4.0 SP2
- Microsoft SNA Server 4.0 SP3
This article was previously published under Q247375 SYMPTOMS
When stress-testing an Active Server Page configured to retrieve DB2 table data
using the Microsoft ODBC Driver for DB2 (included in SNA Server 4.0 Service Pack
3), the IIS process (Inetinfo.exe) may end unexpectedly and log the following
event:
Event ID: 4097
Source: Transaction Server
Description: The run-time environment has detected an inconsistency in its internal state and has terminated the process. Please contact Microsoft Product Support Services to report this error. Error 80040154 from CoCreateInstance of CLSID_MultiThreadedAptHelper (Microsoft Transaction Server Internals Information: File: d:\viper\src\runtime\mtxex\vipthrd.cpp, Line: 382) Data: 80040154
Although the provider has been registered properly, the 80040154 error indicates REGDB_E_CLASSNOTREG, or "class not registered."
WORKAROUND
To prevent this failure, use the native Microsoft OLE DB Provider for DB2
(DB2OLEDB) in the Active Server Page, instead of the Microsoft ODBC
Driver for DB2. Using the native DB2OLEDB interface is also much faster, because
the Microsoft ODBC Driver for DB2 automatically communicates through the
DB2OLEDB Provider.
The following is an example of some VBScript commands that use the DB2OLEDB Provider:
sub CnnSetup(cnn)
cnn.ConnectionTimeout = 60
cnn.CommandTimeout = 60
cnn.Open "Provider=DB2OLEDB;Password=TESTPW;User ID=TESTUSR;Initial Catalog=OLYMPIA;APPC Remote LU Alias=OLYMPIA;APPC Local LU Alias=LOCAL;APPC Mode Name=QPCSUPP;Network Transport Library=SNA;Host CCSID=37;PC Code Page=1252;Package Collection=WNW3XX;Default Schema=WNW3XX;Default Isolation Level=NC;Auto Commit Mode=False;Process Binary as Character=False;Read Only=False"
CnnSetup(ENotesData)
Dim RS
Dim strSQL
Dim dbErrCount
Dim strDest
Dim numEditBtn
Dim numDeleteBtn
strSQL = "SELECT std_comment_seq_no,std_comment_dest,std_comment, SubStr(std_comment,1,250) FROM wnw3xx.erovstdc ORDER BY std_comment_dest ASC, 4 ASC"
Set RS = ENotesData.Execute(strSQL)
WARNING: If the DB2OLEDB provider is using SNA connectivity from an SNA Server
client through an SNA Server located on another computer over TCP/IP, large
numbers of concurrent client requests will cause a large traffic load between
the client and server computer. This is fine, although the SNA Server or client may
encounter the "MaxPendingWrites" limit while writing data on the LAN session,
causing the SNA Server or client to drop the LAN session, indicated when SNA
Server logs event 706. To prevent this, override the MaxPendingWrites registry
key, and increase it to 300 or more. For additional information, click the article number below
