For both outbound and inbound processing, the ODBC transaction logs are stored in the TRLOG table in the ODBC log database. The format of TRLOG is essentially the same as the format of the non-ODBC expanded text transaction log file - with the exception of the first field. In TRLOG, this field is an auto-increment field. (Section 11 contains the layout for the ODBC transaction log.)
ODBC users have only one choice for the creation of the transaction log:
ODBC Database Log Table
The RunID table contains unique sequential run number associated with each map run. This number is incremented each time that a map is executed, regardless of whether the processing is inbound or outbound.
The ODBC trace files for both inbound and outbound processing are stored in a fixed-length file called TRNN.dat, where NN is the Run ID number for the map run.
