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)

sysinfo
SYSINFO(2) Linux Programmer's Manual SYSINFO(2)NAME
sysinfo - return system information
SYNOPSIS
#include <sys/sysinfo.h>
int sysinfo(struct sysinfo *info);
DESCRIPTION
sysinfo() returns certain statistics on memory and swap usage, as well as the load average.
Until Linux 2.3.16, sysinfo() returned information in the following structure:
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* Swap space still available */
unsigned short procs; /* Number of current processes */
char _f[22]; /* Pads structure to 64 bytes */
};
In the above structure, the sizes of the memory and swap fields are given in bytes.
Since Linux 2.3.23 (i386) and Linux 2.3.48 (all architectures) the structure is:
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* Swap space still available */
unsigned short procs; /* Number of current processes */
unsigned long totalhigh; /* Total high memory size */
unsigned long freehigh; /* Available high memory size */
unsigned int mem_unit; /* Memory unit size in bytes */
char _f[20-2*sizeof(long)-sizeof(int)];
/* Padding to 64 bytes */
};
In the above structure, sizes of the memory and swap fields are given as multiples of mem_unit bytes.
RETURN VALUE
On success, sysinfo() returns zero. On error, -1 is returned, and errno is set to indicate the cause of the error.
ERRORS
EFAULT info is not a valid address.
VERSIONS
sysinfo() first appeared in Linux 0.98.pl6.
CONFORMING TO
This function is Linux-specific, and should not be used in programs intended to be portable.
NOTES
All of the information provided by this system call is also available via /proc/meminfo and /proc/loadavg.
