Re: Tracing Physicial File R/W Actions

[Michael Schutte <mschutte369@xxxxxxxxx>]

Just an FYI. We had a program that would run all day, wake up every 10
minutes and rebuild a file.  The programmer was doing it with SQL.  Luckily
it was just a work file.  However, the commit wasn't being done and the
records were getting removed.

So my thought is to check any jobs like this.  While the job is running the
records are there, however, when the job ends and commit wasn't issued,
then they'll disappear.

Our particular issue was a little different.  The non committed records
were not getting saved to our backup server.  Slowing things down, etc.
 Eventually we fixed the program but also excluded this file from backing
up.
