Re: Tuning TrendMicro's DBSCAN

[rob@xxxxxxxxx]

That's the same advice I just received from Trend.  I did ask to speak 
with their AS/400 specialist to see what iSeries specific tuning 
recommendations may be made.  I am still waiting on the call back.

Any concerns about an incremental scan missing something?  For example, I 
run a DBSCAN after I've received an email with the latest and greatest 
virus, and prior to Trend having a new pattern file for it. (Granted, 
they're very diligent and that is a small window of opportunity, but if 
you'd see all the hits that DBSCAN did get...).  Then I run a DBSCAN after 
getting a new pattern file, it will not rescan the databases with that 
latest virus, and I'm toast.

Re: Tuning TrendMicro's DBSCAN






Under the configuration for the Manual and/or Scheduled Database Scan in 
the smconf.nsf database there is an option near the bottom for Incremental 

Scan. Select this option and it will scan docs that have not already been 
scanned.

4 days....WOW!!!
