Hello,
This is RHEL 5.7. swap is almost full, but I am not sure, what to release and how to release space. This is production server so I would like to try all possible options before reboot.
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.
PS mkswap doesn't work on my machine. ( I have swap and... (5 Replies)
Can you help. My server sunning solaris 9 on x86 platform pretty much hung for a few hours... I could not use telnet or ssh to the box - it kept refusing connection. A few hours later - I was able to log in again.
The server has not rebooted but here are the first errors in the messages log... (5 Replies)
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.

Hello all,
The issue is
# df -h /tmp
Filesystem size used avail capacity Mounted on
swap 4.0G 4.0G 8.7M 100% /tmp
# du -sh /tmp/
87M /tmp
By now you probably will say that this is open file destriptor issue.
Well no, nothing... (2 Replies)

FREE(1) User Commands FREE(1)NAME
free - Display amount of free and used memory in the system
SYNOPSIS
free [options]
DESCRIPTION
free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by the ker-
nel. The information is gathered by parsing /proc/meminfo. The displayed columns are:
total Total installed memory (MemTotal and SwapTotal in /proc/meminfo)
used Used memory (calculated as total - free)
free Unused memory (MemFree and SwapFree in /proc/meminfo)
shared Memory used (mostly) by tmpfs (Shmem in /proc/meminfo, available on kernels 2.6.32, displayed as zero if not available)
buffers
Memory used by kernel buffers (Buffers in /proc/meminfo)
cached Memory used by the page cache (calculated as Cached - Shmem in /proc/meminfo - the Cached value is actually the sum of page cache
and tmpfs memory)
OPTIONS -b, --bytes
Display the amount of memory in bytes.
-k, --kilo
Display the amount of memory in kilobytes. This is the default.
-m, --mega
Display the amount of memory in megabytes.
-g, --giga
Display the amount of memory in gigabytes.
--tera Display the amount of memory in terabytes.
-h, --human
Show all output fields automatically scaled to shortest three digit unit and display the units of print out. Following units are
used.
B = bytes
K = kilos
M = megas
G = gigas
T = teras
If unit is missing, and you have petabyte of RAM or swap, the number is in terabytes and columns might not be aligned with header.
-c, --count count
Display the result count times. Requires the -s option.
-l, --lohi
Show detailed low and high memory statistics.
-o, --old
Display the output in old format, the only difference being this option will disable the display of the "buffer adjusted" line.
-s, --seconds seconds
Continuously display the result delay seconds apart. You may actually specify any floating point number for delay, usleep(3) is
used for microsecond resolution delay times.
--si Use power of 1000 not 1024.
-t, --total
Display a line showing the column totals.
--help Print help.
-V, --version
Display version information.
