The procedure to get numbers of installed patches on solaris

getpatchlevel ()                # This subprocedure generates the list of installed pathes and makes
                               # a readable output 

declare -a patch    # The array contains the all installed patches numbers
count=0             # The amount of array member

for i in `showrev -p | cut -c1-70 | awk '{print $2}'`
do
    patch[$count]=`echo $i`
    let "count = $count+1"
done

#Make the readable output: 6 patch per string
k=0
while [ $k -lt ${#patch[@]} ]
do
    echo ${patch[$k]} ${patch[$k+1]} ${patch[$k+2]} ${patch[$k+3]} ${patch[$k+4]} ${patch[$k+5]}
    let "k=$k+6"
done

}

File System workload generator

In addition to the previous post:

FileBench looks like a perfect tool for the load generation.

Here is the article explaining why dd is not the best way to measure HDD performance. The main point is no multithreading in it. vdbench is recommended.

Get application pid listening on a network port in Solaris (aka netstat -npl in Solaris?)

Source link


#!/bin/bash

# Get the process which listens on port

# $1 is the port we are looking for

if [ $# -lt 1 ]; then
echo "Please provide a port number parameter for this script"
echo "e.g. $0 22"
exit
fi

echo "Greping for your port, please be patient (CTRL+C breaks) ... "

for i in `ls /proc` ; do
pfiles $i | grep AF_INET | grep $1
if [ $? -eq 0 ] ; then
echo Is owned by pid $i
fi
done


To research: In comments to the original post somebody offers to use lsof.

How do I know my global zone nodename from a non-global zone ?

That's what I found on the Web.

For Solaris Zones, the method I use is the one devised by Menno Lageman (http://blogs.sun.com/menno). Mount the global zone's /etc/nodename using a read-only LOFS mount on /etc/chassis in the non-global zone. It automatically changes whenever the nodename of the global zone changes, whether it is because the name of the global zone is modified or because the zone is moved to another physical host using zoneadm detach/attach. Just do this:


# zonecfg -z zone

zonecfg:zone> add fs

zonecfg:zone:fs> set dir=/etc/chassis

zonecfg:zone:fs> set special=/etc/nodename

zonecfg:zone:fs> set type=lofs

zonecfg:zone:fs> add options ro

zonecfg:zone:fs> end

I did not try this yet, I have no appropriate Solaris box by hand. But that could be useful.

NTFS and Solaris

Derek Crudgington in his blog reported about read support for NTFS in Solaris 10:

# wget http://www.belenix.org/binfiles/FSWpart.tar.gz
# wget http://www.belenix.org/binfiles/FSWfsmisc.tar.gz

Untar them, pkgadd them, and you are done. Then simply:

# mount -F ntfs /dev/dsk/c0d0pX /mnt

And nice command to view partitions:

# prtpart /dev/rdisk/c0d0p0 -ldevs

Very good news.
