Subject: Re: PGA on higher version
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
