top command on hp-ux
Ok have a hp-ux server with allegedly 8Gb of memory.I do a topand the memory bit comes back:
Memory: 5711504K (2178356K) real, 9770932K (4077104K) virtual, 28528K free Page# 1/18
I'm not sysadmin, and I don't understand unix all that well.
We're running three databases off this box:
database 1 total SGA = 5072 Mb
database 2 total SGA = 368 Mb
database 3 total SGA = 224 Mb
Databases 2 and 3 are slow, there's a lot of waits on latches coming free.
So yes there's a memory issue, but how do I find out the amount of memory on the box, Grid reports 8GB, but whats the difference between virtual and real? I thought virtual was when the system starts swapping out etc.
Basic and stupid question maybe, but after some help.
