Martin,
Thanks. My interpretation was a bit different. I thought, well, if you need
to set the underscore parameters, then why have the 'alter system' command.
At that point, everything will be Monitored automatically anyway.

Hi Henry,
It seems, information oracle shares regarding underscore parameters is
vague as always.
A quite good source is
https://sqlmaria.com/2017/08/01/getting-the-most-out-of-oracle-sql-monitor/
.
There Maria states, you can enforce monitoring with force=true , but then
immediately the limits are explained.
I read id the way, by force=true, sqlmonitoring is "basically" triggered.
Then it still follows all the rules & limitations, e.g.
_sqlmon_max_planlines.
This all is only my interpretation. Still I'd recommend to increase
_sqlmon_max_planlines. Maybe you can limit it to the sessions in question
to limit it's impact.

Has anyone gotten "alter systems set events 'sql_monitor [sql:xxxxxxx]
force-true'" to work? I'm on 12.1.0.2, enabled monitoring for a sql_id
whose plan is greater than the default for monitoring (> 300 lines). I can
see the sql running, but it isn't being monitored.
Anyone else see this?
Thanks.
