All,
I am using SOLARIS 7. I have formated my hard drive to consist of only 150MB of swap space. This isn't enough considering I am running Oracle. How do I create additional swap space?
Please list sources or commands.

Could someone please explain how you know how much swap space you have on your system. See below:
# swap -s
total: 8225048k bytes allocated + 4863488k reserved = 13088536k used, 4008032k available
# swap -l
swapfile dev swaplo blocks free

Hi,
i have done a blunder here, i increased the swap space on Xen5.6 server machine using below steps :-
1056 dd if=/dev/zero of=/root/myswapfile bs=1M count=1024
1057 ls -l /root/myswapfile
1058 chmod 600 /root/myswapfile
1059 mkswap /root/myswapfile
1060 swapon /root/myswapfile

Dear All,
I have a swap space of 16G available in Sol 10. I have allocated it as a seperate file system. But when the RAM Is full used , the system gets rebooted and the swap is not being used,.
Any reasons for this.

CENT OS 5.8 server running with a huge java application which uses up all my ram (4GB) and requires excess of atleast 2GB.But the swap is not getting used up((8GB) of swap space left unused) leading a wierd error and stopping application to stop working.
Any one here dealt with the same kind of... (2 Replies)
I've to install Oracle binaries (I'm oracle DBA) and for that I've extend swap space in my home computer. My situation is like this.
# parted -s /dev/sda print free
Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sda: 38.7GB
Sector size (logical/physical): 512B/512B

LVEXTEND(8) System Manager's Manual LVEXTEND(8)NAME
lvextend - extend the size of a logical volume
SYNOPSIS
lvextend [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--noudevsync] [-i|--stripes Stripes [-I|--stripesize
StripeSize]] {-l|--extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] | -L|--size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]}
[-f|--force] [-n|--nofsck] [-r|--resizefs] [-t|--test] [-v|--verbose] LogicalVolumePath [PhysicalVolumePath[:PE[-PE]]...]
DESCRIPTION
lvextend allows you to extend the size of a logical volume. Extension of snapshot logical volumes (see lvcreate(8) for information to cre-
ate snapshots) is supported as well. But to change the number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm for common options.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
-l, --extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Extend or set the logical volume size in units of logical extents. With the + sign the value is added to the actual size of the
logical volume and without it, the value is taken as an absolute one. The number can also be expressed as a percentage of the total
space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the suffix %LV, of the
remaining free space for the specified PhysicalVolume(s) with the suffix %PVS, as a percentage of the remaining free space in the
Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the total space in the Origin Logical Volume with the
suffix %ORIGIN. The resulting value is rounded upward.
-L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Extend or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for terabytes, P
for petabytes or E for exabytes is optional. With the + sign the value is added to the actual size of the logical volume and with-
out it, the value is taken as an absolute one.
-i, --stripes Stripes
Gives the number of stripes for the extension. Not applicable to LVs using the original metadata LVM format, which must use a sin-
gle value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the stripes. Not applicable to LVs using the original metadata LVM format,
which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9)
-f, --force
Proceed with size extension without prompting.
-n, --nofsck
Do not perform fsck before extending filesystem when filesystem requires it. You may need to use --force to proceed with this
option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of that logical volume by 54MB on physical volume /dev/sdk3. This is
only possible if /dev/sdk3 is a member of volume group vg01 and there are enough free physical extents in it.
"lvextend /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that logical volume by the amount of free space on physical volume
/dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line.
"lvextend -L+16M vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9"
tries to extend a logical volume "vg01/lvol01" by 16MB using physical extents /dev/sda:8-9 and /dev/sdb:8-9 for allocation of extents.
