Agenda

4. 4
Resource savings through fewer repeat collections
tfactl floodcontrol
Flood control
Each event which TFA
automatically generates
a collection for, now has
a flood control limit
The flood control limit instructs TFA
to only collect a certain amount of
times for the same event and then
pause collection for that event
for a set duration
Avoids unnecessary repeat
collections for similar events
and helps conserve system
resources

5. 5
TFA CPU usage can be limited on Linux with:
For example to limit to 50% of a CPU use:
TFA won't use more CPU than you want
tfactl setresourcelimit [-value value]
tfactl setresourcelimit -value 0.5
Minimum of 0.5
Maximum of 4 or 75% of available CPU
(whichever is lower)

6. 6
Easier to upload diagnostic collections
tfactl setupload
ORAchk/EXAchk TFA
tfactl setupload
-name mysqlnetconfig
-type sqlnet
tfactl setupload
-name mos
-type https
tfactl setupload
-name mos
-type https
-proxy www-proxy.example.com:80
Configure ORAchk results to
be uploaded to a database
Configure TFA results to be
uploaded to a MOS
Include a proxy in the MOS
upload configuration
