System Crashes? You mean OS right? 

If your OS admins say, the server is crashing / hanging because of a paging, then it seems you don't have required amount of Memory on your machine. So if that's the case, you need to decrease the SGA, increasing will trigger more paging.

Ask OS admin to give the details about this paging issue.

Hello Erman,

I can't use DBUA for  this upgrade. X-11 forwarding is not supported for this system. I executed the script
catctl.pl

https://docs.oracle.com/database/121/UPGRD/upgrade.htm#CHDBHAHE 

The instance freezes. I contacted the os Admin, they are telling me

There were errors on paging. The system crashes as the Database start due to memory usage and Virtual Memory settings.

Do I increase the memory in database?

Regards,
Roshan
