Thank you. I will look into those options.
Is it good practice to let the pga_aggregate_limit set as NULL i.e. no hard
limit defined(like it was in previous versions) so that it can go max upto
the available memory in the host?

Another advisor that can consume significant PGA is statistics advisor.
We’ve switched it off too.

Pap,
I have also been confronted with an increase in PGA consumption recently
because of MMON_SLAVE not freeing up its used PGA memory. There is a MOS
note which explains this issue
*High PGA Consumption By Mmon Slaves In The Server (Doc ID 2700130.1)*
I have also disabled the tunning advisor and the ADDM generation because I
have observed a PGA leak when the ADDM advisor is launched as well.
*Bug 31695062 - PGA Leak in ADDM Advisor Framework (Doc ID 31695062.8)*
This is why for almost all 19c applications I am working on, I tend to
disable both the tuning advisor and the space advisor
Best regards
Mohamed
