Max size memory asigned to database

Hello

I currently have an Oracle RAC with three servers :

  • server1 - > 94G OS   (59G assigned to "memory_target" and "memory_max_target")
  • server2 - > 94G OS   (59G assigned to "memory_target" and "memory_max_target")
  • server3 - > 503G OS (300G assigned to "memory_target" and "memory_max_target")

I understand that the amount of SGA and PGA are the sum of the assigned "memory_target" and "memory_max_target" in the case of the same value indicated.

But my question is: What is the maximum value that can be assigned to these parameters without affecting the operating system?

In this specific case How do I know if I can increase the value of "memory_target" and "memory_max_target" without affecting the operating system?

Howdy, Stranger!
