Increase /tmp and /var/run filesystems

Fellow managers,

Related to my Oracle problem this morning, I saw something that could
be the problem. Despite de fact that my swap filesystem is 4 Gb. in
size, the tmpfs filesystems are very very smalls:

df -k:
swap 195840 16 195824 1% /var/run
swap 195840 16 195824 1% /tmp

My quick question is: how can I increase it to be, by default, at least
10 times bigger? Is it in the kernel (/etc/system) that we specify it?
I found that the "mount -F tmpfs -o size=<size needed> swap <mount
point>" is working, but is there another way to "force" it without
passing by the /etc/vfstab file?

How does Solaris fix these filesystems size? Why, in this case, I have
only 195 Mb.?

Thanks in advance and will summarise!
