Okay, I will take on session on the handling these zombie process and OS wait events. 1. Ideally we need to kill those zombie process 2. For the OS wait events we need to check further why those are waiting, waiting for resource or waiting for CPU or waiting for client process and then we need to take appropriate action

Can you put your previous session link here pls

Hi Mallik I can see my Swap memory usage even we have physical memory free, is it good or bad and why it is using swap memory

@Mallik034

4 жыл бұрын

1. Swap is Disk memory which is slower than Physical memory (RAM) 2. Your DB or application should not use any swap memory if you have free memory. 3. Swap memory should be used only when you exhaust complete physical memory that not longer time. 4. If you are seeing swap memory usage regularly then you need to either increase your physical memory or tune your database by restricting memory limits. 5. If you see swap memory usage even thought there is free physical memory then some settings miss config in server. /etc/sysctl.conf check for swappiness. Also check for linux memory configuration and tune your linux server accordingly.

@@Mallik034is there any way to allocate swap memory to database? Generally we will allocate memory to database that will take from physical memory and that is not swappable memory and it will not go beyond that memory Can you please tell me if it needs more memory than allocated one it will use from swap?

SGA will take from RAM and it will not go more than what defined. But PGA will go more than what allocated in 11g. To avoid that starting from 12c new parameter PGA_agregate_limit parameter introduced
