    Seems that I have too much of swap being "reserved":

    oracledev# swap -l
    swapfile dev swaplo blocks free
    /dev/md/dsk/d2 85,2 16 8389632 8389632
    oracledev# swap -s
    total: 611120k bytes allocated + 4145568k reserved = 4756688k used, 188928k
    available

    So the tmpfs uses all that is left by the swap... ..am I right? If so, how
    can I "control" the reserved swap to solve my problem?

    Thanks in advance!

    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!

    Ben Audet
