Procedure to add a swap file

a) Login as the root user

b) Type following command to create 512MB swap file (1024 * 512MB = 524288 block size):
# dd if=/dev/zero of=/swapfile1 bs=1024 count=524288

c) Set up a Linux swap area:
# mkswap /swapfile1

d) Activate /swapfile1 swap space immediately:
# swapon /swapfile1

e) To activate /swapfile1 after Linux system reboot, add entry to /etc/fstab file. Open this file using text editor such as vi:
# vi /etc/fstab

Append following line:
/swapfile1 swap swap defaults 0 0

So next time Linux comes up after reboot, it enables the new swap file for you automatically.

g) How do I verify swap is activated or not?
Simply use free command:
$ free -m

File Descriptors

A file descriptor is a handle created by a process when a file is opened. There is a limit to the amount of file descriptors per process. The default Solaris file descriptor limit is 64.

If the file descriptor limit is exceeded for a process, you may see the following errors:

"Too Many Open Files"
"Err#24 EMFILE" (in truss output)

To display a process' current file descriptor limit, run /usr/proc/bin/pfiles pid | grep rlimit on Solaris systems.

Display system file descriptor settings:
ulimit -Hn (hard limit, cannot be exceeded)
ulimit -Sn / ulimit -n (soft limit may be increased to hard limit value)

Increasing file descriptor settings for child processes (example):
$ ulimit -Hn
1024
$ ulimit -Sn
64
$ ulimit -Sn 1024
$ ulimit -Sn
1024

Solaris kernel parameters:
rlim_fd_cur: soft limit

It may be dangerous to set this value higher than 256 due to limitations with the stdio library. If programs require more file descriptors, they should use setrlimit directly.

rlim_fd_max: hard limit

It may be dangerous to set this value higher than 1024 due to limitations with select. If programs require more file descriptors, they should use setrlimit directly.

To count number of open file descriptors:

#!/bin/bash
var=`ps -fea | grep named | grep -v pts | awk '{ print $2 }'`
for i in $var; do
npfiles=`/usr/proc/bin/pfiles -n $i | tail +3 | wc -l` ;
echo "Number of Open File Descriptors per named Process: PID=$i : Num OPFD=$npfiles";
done


http://www.princeton.edu/%7Eunix/Solaris/troubleshoot/filedesc.html

SOLUTION: Using FD_SETSIZE to allow application to use more than 1024 file descriptors

The application core dumped after attempting to access more file descriptors than allowed by the 32-bit library.

From the manpage for select(3C) :

"The default value for FD_SETSIZE (currently 1024) is larger than the default limit on the number of open files. To accommodate 32-bit applications that wish to use a larger number of open files with select(), it is possible to increase this size at compile time by providing a larger definition of FD_SETSIZE before the inclusion of.

The maximum supported size for FD_SETSIZE is 65536. The default value is already 65536 for 64-bit applications."

And from /usr/include/sys/select.h :

#ifndef FD_SETSIZE
#ifdef _LP64
#define FD_SETSIZE 65536
#else
#define FD_SETSIZE 1024
#endif /* _LP64 */
#elif FD_SETSIZE > 1024 && !defined(_LP64)
#ifdef __PRAGMA_REDEFINE_EXTNAME
#pragma redefine_extname select select_large_fdset
#else /* __PRAGMA_REDEFINE_EXTNAME */
#define select select_large_fdset
#endif /* __PRAGMA_REDEFINE_EXTNAME */
#endif /* FD_SETSIZE */

On Solaris[TM] 7, 8, 9, and 10 one can over come the 1024 32-bit library file descriptors limit by redefining the maximum allowed library limit and recompiling the source code with the following lines added.

        #define FD_SETSIZE 65535
      #include 

The FD_SETSIZE is the library file descriptor limit. After adjusting the library limit, it is necessary to adjust the system limit of file descriptors. This can be done by adding the following lines to the etc/system file and then rebooting.

        set rlim_fd_cur 1024
      set rlim_fd_max 65535

To adjust the current soft limit of allowable system file descriptors above 1024 for an application without adjusting the system soft limit, one should use the "ulimit -n [limit]" or "limit descriptors [limit]" commands before starting applications that require more than 1024 file descriptors.

The value can not exceed the maximum in the table below.

default soft limit | default hard limit | max for stdio | max for select()

Solaris[TM] 2.4-2.6 64 1024 256 1024

Solaris[TM] 7 (32-bit) 64 1024 256 65535 (with recompile)

Solaris[TM] 7 (64-bit) 64 1024 256 65535

Solaris[TM] 8 (32-bit) 256 1024 256 65535 (with recompile)

Solaris[TM] 8 (64-bit) 256 1024 256 65535

Solaris[TM] 9 (32-bit) 256 65535 256 65535 (with recompile)

Solaris[TM] 9 (64-bit) 256 65535 256 65535

Solaris[TM] 10 (32-bit) 256 65535 256 65535 (with recompile)

Solaris[TM] 10 (64-bit) 256 65535 256 65535

Please note that for applications that use the Berkeley stdio.h interface (i.e. fopen/fclose/fread/fwrite, etc), the maximum number of open file descriptors per process is 256.

With the exception of databases and WebServers, most applications never need more than 256 open file descriptors. Also starting with Solaris[TM] 7, the plimit(1) command can be used to adjust the soft and hard limits of a running process.

plimit -n ,

The poll() system call has the number of file descriptors being polled passed in as an argument, so it has none of the above limitations.

How to configure NIC in LINUX

To configure a static IP (an IP that will never change) in debian you must edit the file
/etc/networking/interfaces and put the following:

CODE

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # The loopback interface auto lo iface lo inet loopback # The first network card - this entry was created during the Debian installation # (network, broadcast and gateway are optional) auto eth0 iface eth0 inet static address 192.168.1.10 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1

The last section is the most important, the top may or may not be the same so don't play with it unless you get an error. In this case the IP of the server is 192.168.1.10 so if you run it as a DNS server for example, you can set that in your router's config and not worry about it changing.

To apply this configuration type /etc/init.d/networking restart

You'll get a message that it's restarting the network interface, then you'll get booted off ssh (because the IP changed) so reconnect using the new IP and it should work.

In red hat this file is /etc/sysconfig/network-scripts/ifcfg-eth0 and you would put this in it:

CODE

DEVICE=eth0 BOOTPROTO=static ONBOOT=yes IPADDR=192.168.1.10 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 To apply this configuration type /etc/init.d/network restart

bge3: flags=1000802 mtu 1500 index 6
inet 0.0.0.0 netmask 0
ether 0:3:ba:9b:ab:ec

5. Configure IP Address and Default gateway:

root@agendacon # ifconfig bge3 192.168.100.200 netmask 255.255.255.0 up
root@agendacon # ifconfig bge3
bge3: flags=1000803 mtu 1500 index 6

ufsdump

This Tech Tip describes a backup and restore procedure for the Solaris 8 or 9 Operating System using the ufsdump command.

Backing Up the OS

1. For this example, we are using c0t0d0s0 as a root partition. Bring the system into single-user mode (recommended).

# init -s

2. Check the partition consistency.

# fsck -m /dev/rdsk/c0t0d0s0

3. Verify the tape device status:

# mt status

Or use this command when you want to specify the raw tape device, where x is the interface:

# mt -f /dev/rmt/x status

4. Back up the system:

a) When the tape drive is attached to your local system, use this:

# ufsdump 0uf /dev/rmt/0n /

b) When you want to back up from disk to disk, for example, if you want to back up c0t0d0s0 to c0t1d0s0:

# mkdir /tmp/backup
# mount /dev/dsk/c0t1d0s0 /tmp/backup
# ufsdump 0f - / | (cd /tmp/backup;ufsrestore xvf -)

c) When you want to back up to a remote tape, use this. On a system that has a tape drive, add the following line to its /.rhosts file:

hostname root

where hostname is the name or IP of the system that will run ufsdump to perform the backup. Then run the following command:

# ufsdump 0uf remote_hostname:/dev/rmt/0n /

Restoring the OS

1. For this example, your OS disk is totally corrupted and replaced with a new disk. Go to the ok prompt and boot in single-user mode from the Solaris CD.

ok> boot cdrom -s

2. Partition your new disk in the same way as your original disk.

3. Format all slices using the newfs command. For example:

# newfs /dev/rdsk/c0t0d0s0

4. Make a new directory in /tmp:

# mkdir /tmp/slice0

5. Mount c0t0d0s0 into /tmp/slice0:

# mount /dev/dsk/c0t0d0s0 /tmp/slice0

6. Verify the status of the tape drive:

# mt status

If the tape drive is not detected, issue the following command:

# devfsadm -c tape

or

# drvconfig
# tapes
# devlinks

Verify the status of tape drive again and make sure the backup tape is in the first block or file number is zero. Use the following command to rewind the backup tape:

# mt rewind

7. Go into the /tmp/slice0 directory and you can start restoring the OS.

# cd /tmp/slice0
# ufsrestore rvf /dev/rmt/0n

If you want to restore from another disk (such as c0t1d0s0), use the following command:

# mkdir /tmp/backup
# mount /dev/dsk/c0t1d0s0 /tmp/backup
# ufsdump 0f - /tmp/backup | (cd /tmp/slice0;ufsrestore xvf -)

8. After restoring all the partitions successfully, install bootblock to make the disk bootable. This example assumes your /usr is located inside the "/" partition:

# cd /tmp/slice0/usr/platform/'uname -m'/lib/fs/ufs
# installboot bootblk /dev/rdsk/c0t0d0s0

9. To finish restoring your OS, reboot the system.

Intruducion.
"Network is of Computers", si guiendo este lema debemos dar gran importacia a los avances que tenemos en tecnologia de OS. En este articulo vamos a trabar sobre xVM, siendo esta la plataforma de virtualizacion adopdatada por SUN Microsystem, la cual esta siendo integrada con el producto estrella de de SUN o la "Joya de la corona", Solaris 10. Ustedes se preguntaran porque sobre solaris y no sobre LINUX, siendo que en xVM el core es "XEN Opensource"?, principalmente por que el respaldo de SUN lo potencializa en el mercado Enterprise.
