i needed a bigger swap, its size was 2 Gb and we needed it to grow to 16gb, so we decided to shrink /. A task anybody
would say not possible.
So we tuck in the first installation CD for oracle enterprise linux and when prompted for a kernel option we
issued
: linux recover
Once asked to mount the root partition we said yes…
it ended up in /dev/VolGroup00/LogVol00
we checked a df -k, and it was mounted as /mnt/sysimage, and had a dev, proc and other directories
mounted inside, which were not evident in the df -k, so did a
# cat /etc/mtab
and found other dirs mounted, so for each entry in mtab inside /mnt/sysimage we unmounted it, and ended
up unmounting /mnt/sysimage
#umount /mnt/sysimage/selinux
#umount /mnt/sysimage/dev
#umount /mnt/sysimage/sys
#umount /mnt/sysimage/proc
#umount /mnt/sysimage/boot
#umount /mnt/sysimage
To reduce the filesystem, after unmounted and we issued:
# e2fsck -f /dev/VolGroup00/LogVol00
# resize2fs /dev/VolGroup00/LogVol00 110G
After that we needed to resize the volume, so we issued:
# lvm
> lvreduce -L -16G /dev/VolGroup00/LogVol00
And that did the trick to reduce the / filesystem
Then we booted up the server and resized the swap volume issuing:
# lvresize -L +16G /dev/VolGroup00/LogVol01
Had to remake the swap area
190/433
# swapoff /dev/VolGroup00/LogVol01
# mkswap /dev/VolGroup00/LogVol01
And remount it
# swapon -a
You can verify the new swap size with a “top”

You have to create it in the global zone, add it with zoneconfig, then mount it manually from the global zone
 bash-3.00# zonecfg -z zones004z3
 zonecfg: zones004z3> add fs
 zonecfg: zones004z3:fs> set dir=/myzone/cpbatch
 zonecfg: zones004z3:fs> set special=/dev/md/dsk/d132
 zonecfg: zones004z3:fs> set raw=/dev/md/rdsk/d132
 zonecfg: zones004z3:fs> set type=ufs
 zonecfg: zones004z3:fs> end
 zonecfg: zones004z3> verify
 zonecfg: zones004z3> commit
 zonecfg: zones004z3> exit
 bash-3.00# mount /dev/md/dsk/d132 /zones/CHB/myzone/cpbatch

I have this graphics card in a sunblade150, and thought it could be configured using m64config. I tried to, but it did not
work.
For this card, you must use “fbconfig”
# fbconfig -dev /dev/fbs/jfb0 -defdepth 24 -res 1280x1024x76 now
did the trick

You ever wanted to see what connections are in place to your server?
I wrote a script called /usr/bin/conn with this:
netstat -na | egrep ‘tcp’ | grep -v LISTEN
and then just ran
# chmod 755 /usr/bin/conn
# watch conn
and now i’m watching the live connections!

To get this week’s top ten from the web, you can first ask billboard using topten.ksh:
#!/bin/ksh
echo “—- getting bilboard’s heatseeker”
curl
158/433
“http://206.130.124.43//htmlsite/html_top.php?id=23&CALL_URL=http%3A//www.billboard.com/bbcom/charts/chart_display.jsp%3Fg%3DSingles%26f%3DHot%2 BDance%2BClub%2BPlay”
> /tmp/bb-hs.txt
cat /tmp/bb-hs.txt | sed -e ‘s/<[^>][^>]*>//g’ -e ‘/^ *$/d;s// /g;s/Featuring//g;s/ the //g’ | tr -s ‘ ‘ | grep “|”|
grep -iv billboard| cut -d ” ” -f4-9 > terms.txt
The top ten list is parsed and ends up as a text only list in “terms.txt”. We now proceed to search and
download the files both from filestube and skreemr, we use a PHP script called mysearch.php to look for files
in filestube(remembver to use your own key for filestube instead of XXXXXXXX):
#!/usr/bin/php
<?php
// Correct English grammar…
$argc > 1 x y z $plural = ‘s’ : $plural = ”;
// Display the number of arguments received
//fwrite(STDOUT, “Got $argc argument$pluraln”);
$args=””;
// Write out the contents of the $argv array
foreach ( $argv as $key => $value ) {
// fwrite(STDOUT,”$key => $valuen”);
if($key!=0){
if($key>1){
$args=”{$args}%20{$value}”;
}else{
$args=”{$value}”;
}
}
}
//print “args are:”;

Then we direct all the show with get.ksh:
#!/bin/ksh
#### Get the files from FilesTube
(cat terms.txt| while read line;do
./mysearch.php `echo $line | awk ‘{ print $1 ” ” $2 }’`| grep -i `echo $line | awk ‘{ print $3 }’` | head -1
done) >/tmp/results.txt
(cat /tmp/results.txt | while read result;do
curl “`echo $result | awk -F’|’ ‘{ print $2 }’| sed ‘s/ //g’`” | egrep ‘src.*mp3’ | awk -F”src=”” ‘{ print $2 }’ | awk ‘{
161/433
print $1 }’ | sed ‘s/”//g’
done) | while read url;do
wget -P /200gb/AUTODOWNLOADS “$url”
done
rm /tmp/results. txt
#### Or get them from skreemr
(cat terms.txt| while read line;do
st=`echo $line | awk ‘{ print $1 “+” $2 “+” $3 }’`
wget -P /200gb/AUTODOWNLOADS `curl “http://skreemr. com/results.jsp? q=$st” | egrep ‘href.*mp3’ | awk
-F”href=” ‘{ print $2 }’ | head -1 | sed ‘s/”//g’`
done)
The order of execution is: first “topten.ksh”, to get the list, then “get.ksh” to get the tracks.

To make a differential copy, so you copy all files in /a that are not in /b, you can do:
# cd /a
#/usr/local/bin/tar pcf – kraftek.html POSTS rescue rescued.html rescued.txt x y z | ( cd /b; /usr/local/bin/tar kxfp – )
The clue here is the “k” option, to keep existing files
compare directories for missing files
So you made a copy of /a into /b, but you see /b has less files, how to know which files are missing in /b x y z
# find /a | sort > as.txt
# find /b | sort > bs.txt
# comm -23 as.txt bs.txt
the last command will show the files that are in /a that are not in /b

Unmount your ext2 filesystem, then issue:
# tune2fs -j /dev/hda1
Where /dev/hda1 is the ext2 FS you want to convert.
then edit your fstab and change /dev/hda1 entry to be ext3
Easy!

to know how many cpus do you have there:
# cat /proc/cpuinfo
to know memory info
# cat /proc/meminfo

ok, just hang with me while I learn NB.
some jobs were stalled in a machine, so we went to the media server and checked if the jobs were pending
and the tape drives were not in “TSD”:
bash-3.00# /usr/openv/volmgr/bin/vmoprcmd
PENDING REQUESTS
<NONE>
DRIVE STATUS
Drv Type Control User Label RVSN EVSN Ready Wr.Enbl. ReqId
0 dlt TSD – No – –
1 dlt TSD root Yes EBI219 EBI219 Yes Yes 1
ADDITIONAL DRIVE STATUS
Drv DriveName Multihost Assigned Comment
0 QUANTUMDLT70000 No –
1 QUANTUMDLT70001 No ebitdb1
In the “pending” section there were jobs pending on drv 1 and 0, and the tape drives were unavailable, so we
reset them:
# vmoprcmd -deny 0
# vmoprcmd -deny 1
# vmoprcmd -up 0
# vmoprcmd -up 1
We assumed the drives were recently fed with tapes, so after this jobs were running ok.
To see the active jobs…
#bpdbjobs -report |grep -i act
To see the queued jobs…
#bpdbjobs -report | grep -i que
To kill a job
#bpdbjobs -kill <job#>
To see the job summary…
#/usr/openv/netbackup/bin/bpdbjobs -summary
#bpps -a
To run an inventory on a tape library…
#bpinvent 0
259/433
Check last 24 hour’s errors
#bperror -U -backstat -hoursago 24
See available tapes
# available_media
Or go to bpadm – media mgmt – special actions – Inventory a Robot and Compare with Volume Configuration
To see if a tape is in the correct pool
#vmquery -m <mediaid>
To change a tape of pool
# vmchange -h ntxldb2 -p 1 -m NTXD53
(Where 1 is NetBackup and 2 is systems)
To see the pools
#vmpool -listall
A monitoring loop:
# while true;do clear; vmoprcmd; echo “active”; bpdbjobs -report |grep -i act;echo “queued”; bpdbjobs -report
|grep -i que;bpdbjobs -summary; bperror -U -backstat -hoursago 24| tail -15l; sleep 5; clear; done
Run bpadm for interactive actions
# bpadm
