Not All ODBC Logging Posts Logged in Database

• Microsoft Commercial Internet System version 2.0

SYMPTOMS

When you are performing ODBC logging into an Access database, you may notice that all posts are not logged.

For example, the first session (poststress.pl) logs the first 455 of 500 total posts. The second session (poststress2.pl) logs the first 167 of 500 total posts.

Both sessions show that logging terminates after about 32 seconds (judging by the LogTime log field). The only difference between the scripts is that poststress2.pl has some arbitrary print statements to the console to slow down its execution. The highest processing time recorded in the logs for the first session is 32,179, and the second session is 32,726; both are just below the range of an integer.

CAUSE

This may be caused by the ProcessingTime field being set to hold int type values. Access dumps a log entry that has invalid data because of the way ProcessingTime is calculated, causing a value larger than 32,768 to be posted to a field allocated to only hold an integer value.

WORKAROUND

To work around this problem, use a long integer type for ProcessingTime. You may also want to use long integers for BytesRecvd and BytesSent, because these will often be larger than an int when dealing with file attachments.
