Hi,
I've encountered a strange problem of memory management on taroon, so I
need you guys' help.
on our server, we've got an oracle Release 9.2.0.6.0 installed. Today,
when I was checking the memory utilization on the server, I found that
there is no shared memory used in the system. I found it is pretty
strange, because I think oracle uses a lot of IPC calls, and at least,
the libraries oracle should be shared between the oracle processes.
some ideas?
thanks in advance,
dux
