Using Centos DVD as Yum Repository

Centos coming with dvd/cd as installation media, in some case you want to use it as yum repository. In this tech tips posting, I used centos 6.1 DVD#1. 

1. Mount your dvd media under one of this directory as default :

 a. /media/CentOS/
 b. /media/cdrom/
 c. /media/cdrecorder/

2. edit the configuration : # vi /etc/yum.repos.d/CentOS-Media.repo

      make sure enabled = 1

3. Test # yum --disablerepo=\* --enablerepo=c5-media install groupinstall "X Window System" "GNOME Desktop Environment"

create directory at the same time command 1 of 12

create directory /oracle/oradata 1 of 12


bash>perl -e 'for (1..12) {system("mkdir -p /oracle/oradata$_")};'

create directory {/oraindex } {redolog} {ctl} 1 of 12

bash>perl -e 'for (1..12) {system("mkdir oraindex$_")};'
bash>perl -e 'for (1..12) {system("mkdir redolog$_")};'
bash>perl -e 'for (1..3) {system("mkdir ctl$_")};'


remove directory /oraindex12 of 71 

bash>perl -e 'for (12..71) {system("rm -rf  oraindex$_")};'

You will need to update the bold part above, with your output. You will then run the following command from the OS

# eeprom "nvramrc=devalias rootdisk /pci@1e,600000/ide@d/disk@0,0:a devalias rootmirr /pci@1e,600000/ide@d/disk@1,0:a"

Boot archive error or corrupt

A few weeks ago, I got a little problem with my solaris box, namely solaris won't boot because the boot archive was corrupt, *sigh*. Anyway the boot archive in solaris 10 was contain kernel module and configuration file was needed for solaris to startup the system.
Error:

module /platform/i86pc/boot_archive error 3 bad or corrupt data while decompressing file

Workaround:
Boot up your solaris in "solaris failsafe mode", next solaris image will mount with writeable mode on "/a" mount point

ok> boot -F failsafe

bash> rm -f /a/platform/`uname -i`/boot_archive
bash> bootadm update-archive -R /a
bash> reboot

Kill Many* Jobs

When I want to shutdown the oracle database.

I must kill many session client who connect to the database and running in background Os...

bash> ps -ef|grep -i local=no
oracle 19027     1  0   Sep 07 ?        0:01 oracleSERVER (LOCAL=NO)
oracle 25918     1  0   Sep 07 ?        0:03 oracleSERVER (LOCAL=NO)
oracle 16403     1  0   Sep 07 ?        0:00 oracleSERVER (LOCAL=NO)
oracle 18858     1  0   Sep 06 ?        0:01 oracleSERVER (LOCAL=NO)
oracle  7836     1  0   Sep 07 ?        0:02 oracleSERVER (LOCAL=NO)
oracle  9021     1  0   Sep 07 ?        0:00 oracleSERVER (LOCAL=NO)
Show this the trick (when Nobody give up..:D)

bash> ps -ef|grep LOCAL|awk '{print $2'}|xargs kill -9
