Oracle transactions with asynchronous processes

Question

I am using VB 6 to create 2 asynchronous processes that make
separate connections to an oracle db. One process is
implemented as class by the other and runs as a background task.
Each process has several insert/updates that implement
transactions; every insert/update is followed by a commit.
The background process includes a timer module that includes
some insert/update statements.
There are checks in place to ensure that the processes do not
attempt to close while the timer is executing.
However, when the application exits, it generates a "Connection
object cannot be explicitly closed while in a transaction"
error, usually in the startup foreground app, although sometimes
in the background process.
I can't for the life of me find how a transaction could be open
nor any method to test for an open transaction before trying to
close.
Anyone have any ideas?

Answer 1

Are you doing explicit start/commits in your SQL code, are you
using ODBC's auto-commit feature, or are you using both
simultaneously?
