in EM 12c I have disabled the inactivity timeout with setting:
./emctl set property -name oracle.sysman.eml.maxInactiveTime -value -1
, restarted OMS and it seems to work on e.g. the enterprise overview. But when I open the performance tab of a database, I still get the inactivity popup after ~ 15 minutes.
How to prevent this popup on the performance tab?
