Hello and thanks in advance.
I have a Sun box with raid 1 on the O/S disks using solaris svm.
I want to unmirror my swap partition, and add the slice on the second disk as an additional swap device. This would give me twice as much swap space.
I have been warned not to do this by some... (3 Replies)
I have a file (tmp.out) with contents delimited by '|':

I want to write only the 1st and 3rd columns to another file, but they should be swapped with each other:

Hi
I have an integrity machine rx7620 and rx8640 running hp-ux 11.31. I'm planning to fine tune the system:

- And how much % of memory swap utilization should be specified (swap space device... (6 Replies)

SYSTEMD.SWAP(5) systemd.swap SYSTEMD.SWAP(5)NAME
systemd.swap - Swap unit configuration
SYNOPSIS
swap.swap
DESCRIPTION
A unit configuration file whose name ends in ".swap" encodes information about a swap device or file for memory paging controlled and
supervised by systemd.
This man page lists the configuration options specific to this unit type. See systemd.unit(5) for the common options of all unit
configuration files. The common configuration items are configured in the generic [Unit] and [Install] sections. The swap specific
configuration options are configured in the [Swap] section.
Additional options are listed in systemd.exec(5), which define the execution environment the swapon(8) binary is executed in, and in
systemd.kill(5), which define the way the processes are terminated, and in systemd.resource-control(5), which configure resource control
settings for the processes of the service.
Swap units must be named after the devices or files they control. Example: the swap device /dev/sda5 must be configured in a unit file
dev-sda5.swap. For details about the escaping logic used to convert a file system path to a unit name, see systemd.unit(5).
All swap units automatically get the appropriate dependencies on the devices or on the mount points of the files they are activated from.
Swap units with DefaultDependencies= enabled implicitly acquire a conflicting dependency to umount.target so that they are deactivated at
shutdown.
FSTAB
Swap units may either be configured via unit files, or via /etc/fstab (see fstab(5) for details). Swaps listed in /etc/fstab will be
converted into native units dynamically at boot and when the configuration of the system manager is reloaded. See systemd-fstab-
generator(8) for details about the conversion.
If a swap device or file is configured in both /etc/fstab and a unit file, the configuration in the latter takes precedence.
Unless the noauto option is set for them all swap units configured in /etc/fstab are also added as requirements to swap.target, so that
they are waited for and activated during boot.
OPTIONS
Swap files must include a [Swap] section, which carries information about the swap device it supervises. A number of options that may be
used in this section are shared with other unit types. These options are documented in systemd.exec(5) and systemd.kill(5). The options
specific to the [Swap] section of swap units are the following:
What=
Takes an absolute path of a device node or file to use for paging. See swapon(8) for details. If this refers to a device node, a
dependency on the respective device unit is automatically created. (See systemd.device(5) for more information.) If this refers to a
file, a dependency on the respective mount unit is automatically created. (See systemd.mount(5) for more information.) This option is
mandatory.
Priority=
Swap priority to use when activating the swap device or file. This takes an integer. This setting is optional.
TimeoutSec=
Configures the time to wait for the swapon command to finish. If a command does not exit within the configured time, the swap will be
considered failed and be shut down again. All commands still running will be terminated forcibly via SIGTERM, and after another delay
of this time with SIGKILL. (See KillMode= in systemd.kill(5).) Takes a unit-less value in seconds, or a time span value such as "5min
20s". Pass 0 to disable the timeout logic. Defaults to TimeoutStartSec= in manager configuration file.
Check systemd.exec(5) and systemd.kill(5) for more settings.
