Without using top, how to get swap space of a "subzone" on Solaris 5.10
Hi all,
OS = Solaris 5.10
Without using top, can anyone please advise how to get the current swap space that is assigned to a sub-zone that is part of the Solaris zone? Some of the servers does not have the top command and I do not have access to run zone level commands either like zonecfg etc.
Running swap -s gives which I believe is for the whole zone/container?
top command shows 34G of swap for this server/zone, is that correct? If so, how to get this same information without using top? Will sar or vmstat give me this information?
Hi,
We have a DEC Alpha 4100 Server with OSF1 Digital Unix 4.0.
Can any one tell me, if there are any commands on this Unix which are equivalent to "top" and "sar" on HP-UX or Sun Solaris ?
I am particularly interested in knowing the CPU Load, what process is running on which CPU, etc.

Hi,
I have a process that can be seen after "ps aux" command.
However when I do "top" command. This process
cannot be seen.
How can this happen? Is there anything wrong
with my code? (3 Replies)

Hi Friends,
Can any of you explain me about the below line of code?

Im not able to understand, what exactly it is doing :confused:
Any help would be useful for me.

Ever noticed that using the top command on a multiple cpu box can often give totally misleading answers, like 230%, when you think that 100% should be the max?
Well, that's because top has a bizarre mode called "Irix mode" wherein if you have 4 cpus, the %CPU column of top can go up to 400%. I... (1 Reply)

mkswap
MKSWAP(8) System Administration MKSWAP(8)NAME
mkswap - set up a Linux swap area
SYNOPSIS
mkswap [options] device [size]
DESCRIPTION
mkswap sets up a Linux swap area on a device or in a file.
The device argument will usually be a disk partition (something like /dev/sdb7) but can also be a file. The Linux kernel does not look at
partition IDs, but many installation scripts will assume that partitions of hex type 82 (LINUX_SWAP) are meant to be swap partitions.
(Warning: Solaris also uses this type. Be careful not to kill your Solaris partitions.)
The size parameter is superfluous but retained for backwards compatibility. (It specifies the desired size of the swap area in 1024-byte
blocks. mkswap will use the entire partition or file if it is omitted. Specifying it is unwise - a typo may destroy your disk.)
After creating the swap area, you need the swapon command to start using it. Usually swap areas are listed in /etc/fstab so that they can
be taken into use at boot time by a swapon -a command in some boot script.
WARNING
The swap header does not touch the first block. A boot loader or disk label can be there, but it is not a recommended setup. The recom-
mended setup is to use a separate partition for a Linux swap area.
mkswap, like many others mkfs-like utils, erases the first partition block to make any previous filesystem invisible.
However, mkswap refuses to erase the first block on a device with a disk label (SUN, BSD, ...).
OPTIONS -c, --check
Check the device (if it is a block device) for bad blocks before creating the swap area. If any bad blocks are found, the count is
printed.
-f, --force
Go ahead even if the command is stupid. This allows the creation of a swap area larger than the file or partition it resides on.
Also, without this option, mkswap will refuse to erase the first block on a device with a partition table.
-L, --label label
Specify a label for the device, to allow swapon by label.
-p, --pagesize size
Specify the page size (in bytes) to use. This option is usually unnecessary; mkswap reads the size from the kernel.
-U, --uuid UUID
Specify the UUID to use. The default is to generate a UUID.
-v, --swapversion 1
Specify the swap-space version. (This option is currently pointless, as the old -v 0 option has become obsolete and now only -v 1
is supported. The kernel has not supported v0 swap-space format since 2.5.22 (June 2002). The new version v1 is supported since
2.1.117 (August 1998).)
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
NOTES
The maximum useful size of a swap area depends on the architecture and the kernel version.
The maximum number of the pages that is possible to address by swap area header is 4294967295 (UINT_MAX). The remaining space on the swap
device is ignored.
Presently, Linux allows 32 swap areas. The areas in use can be seen in the file /proc/swaps
mkswap refuses areas smaller than 10 pages.
If you don't know the page size that your machine uses, you may be able to look it up with "cat /proc/cpuinfo" (or you may not - the con-
tents of this file depend on architecture and kernel version).
To set up a swap file, it is necessary to create that file before initializing it with mkswap, e.g. using a command like
# fallocate --length 8GiB swapfile
Note that a swap file must not contain any holes. Using cp(1) to create the file is not acceptable. Neither is use of fallocate(1) on
file systems that support preallocated files, such as XFS or ext4, or on copy-on-write filesystems like btrfs. It is recommended to use
dd(1) and /dev/zero in these cases. Please read notes from swapon(8) before adding a swap file to copy-on-write filesystems.
