Extend root filesystems on Oracle Linux
Before you begin :
1. Verify your new disk is detect on the systems
in this case, I’m using /dev/sdb
2. Identify your volgroup
in this case, my my root vg is vg_allen.
Here we go :
[root@allen ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x079df05d.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

Failed to uninstall the Extension Pack Oracle VM VirtualBox Extension Pack.
Borobudur Temple, West Java - Indonesia : http://en.wikipedia.org/wiki/Borobudur
After uninstalling my VirtualBox, later after that I Re-Install it again. When I wanto uninstall the Extension Pack I got following error :
Failed to uninstall the Extension Pack Oracle VM VirtualBox Extension Pack.
The installer failed with exit code 1: VBoxExtPackHelperApp.exe: error: Failed to rename the extension pack directory: VERR_ALREADY_EXISTS
rcExit=1.
Result Code: E_FAIL (0x80004005)
Component: ExtPackManager
Interface: IExtPackManager {3295e6ce-b051-47b2-9514-2c588bfe7554}
After googlig, I got solution to fix it.. you just have to clean the extension pack with the command line:
C:\Program Files\Oracle\VirtualBox>vboxmanage extpack cleanup Successfully performed extension pack cleanup C:\Program Files\Oracle\VirtualBox>
Try to re-install extension pack, and it installed successfully.

Setting Static IP Address on Solaris 11
Solaris 11 coming with new feature and enhancement, one of it is NWAM (Network automagic) with NWAM you can create and save the network profile. In this post, I’ll blogging about how to configure your Solaris 11 Systems to used static IP Address.
Ok let’s start :
1. Switch From Automatic Network Configuration Mode to Manual Network Configuration Mode
# netadm enable -p ncp DefaultFixed
2. Verify that DefaultFixed profile is applied
# netadm list netadm: DefaultFixed NCP is enabled; automatic network management is not available. 'netadm list' is only supported when automatic network management is active.
3. Determine the interface that you want to configure
# dladm show-phys
4. I’ll configure the net0 interface
# ipadm create-ip net0 # ipadm create-addr -T static -a 192.168.56.200/24 net0/v4
5. Verify
# ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 net0/v4 static ok 192.168.56.200/24 lo0/v6 static ok ::1/128
root@solaris:~# dladm show-link LINK CLASS MTU STATE OVER net0 phys 1500 up -- net1 phys 1500 unknown --
6. Add default route
# route -p add default 12.34.56.1
7. Add DNS Name Server
root@solaris:~# svccfg -s dns/client svc:/network/dns/client> setprop config/nameserver = (8.8.8.8 8.8.4.4) svc:/network/dns/client> listprop config config application config/value_authorization astring solaris.smf.value.name-service.dns.client config/nameserver net_address 8.8.8.8 8.8.4.4 svc:/network/dns/client> exit root@solaris:~# root@solaris:~# svcadm refresh dns/client root@solaris:~# svcadm restart dns/client
8. Set name service switch
root@solaris:~# svccfg -s name-service/switch svc:/system/name-service/switch> setprop config/host = "files dns" svc:/system/name-service/switch> listprop config config application config/default astring files config/value_authorization astring solaris.smf.value.name-service.switch config/printer astring "user files" config/host astring "files dns" svc:/system/name-service/switch> exit
9. Testing
root@solaris:~# ping google.com google.com is alive
That’s it..
In the next post I’ll blogging about how to configure IPMP on Solaris 11.
Configure Local IPS Repository on Solaris 11
Oracle Solaris 11 has been released and coming up as the first cloud OS, Oracle Solaris 11 coming with more features and enhancements. One of it is IPS (Image Packing Systems) this the new way you manage the software patches and packages, IPS make you easy to manage package and patches.
Why you configure Local IPS?
1. Performance (more speed from local network)
2. Security (you don’t want your client to connect to internet)
3. Replication (You want manage the repository, and to make your installation today is exactly the same for the installation next Year)
Prerequisite :
1. Install Oracle Solaris 11
2. 2 DVD ISO repository : https://edelivery.oracle.com
you need to unzip the iso, below the tow iso repository look like :
rachmat@solaris:~$ ls -l *iso -rw-r--r-- 1 rachmat staff 3537872896 Nov 13 06:53 V28915-01.iso -rw-r--r-- 1 rachmat staff 3403360256 Nov 13 14:52 V28916-01.iso
3. Create Zpool for IPS Repository (it’s optional, but I create Zpool specially for holding the repository)
root@solaris:~# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c3t0d0
/pci@0,0/pci8086,2829@d/disk@0,0
1. c3t2d0
/pci@0,0/pci8086,2829@d/disk@2,0
Specify disk (enter its number): ^D
root@solaris:~# zpool create ipspool c3t2d0
root@solaris:~# zfs create ipspool/ips
-optional :
root@solaris:~# zfs set atime=off ipspool/ips
root@solaris:~# zfs set compression=on ipspool/ips
set a time to off for better performance, it’s optional.
4. Mount the first repository iso and rsync it, after finished umount it :
root@solaris:~# lofiadm -a /export/home/rachmat/V28915-01.iso /dev/lofi/1 root@solaris:~# mount -F hsfs /dev/lofi/1 /mnt root@solaris:~# ls /mnt/ COPYRIGHT NOTICES README repo root@solaris:~# rsync -aP /mnt/repo /ipspool/ips root@solaris:~# umount /mnt root@solaris:~# lofiadm -d /dev/lofi/1
5. Mount the second repository iso and rsync it, after finished umount it :
root@solaris:~# lofiadm -a /export/home/rachmat/V28916-01.iso /dev/lofi/1 root@solaris:~# mount -F hsfs /dev/lofi/1 /mnt root@solaris:~# ls /mnt/ COPYRIGHT NOTICES README repo root@solaris:~# rsync -aP /mnt/repo /ipspool/ips root@solaris:~# umount /mnt root@solaris:~# lofiadm -d /dev/lofi/1
6. set the repository to your repository folder, in this case /ipspool/ips/repo
root@solaris:~# svccfg -s application/pkg/server setprop pkg/inst_root=/ipspool/ips/repo
7. Set the readonly to true :
root@solaris:~# svccfg -s application/pkg/server setprop pkg/readonly=true
8. Enable and refresh pkg serer :
root@solaris:~# svcadm refresh application/pkg/server root@solaris:~# svcadm enable application/pkg/server
9. setting up the client, to use only this repository
root@solaris:~# pkg set-publisher -G '*' -g <origin> solaris
Where the origin is your repository server domain / ip address
root@solaris:~# pkg set-publisher -G '*' -g http://10.0.7.1 solaris
10. Verify and testing :
root@solaris:~# pkg publisher
PUBLISHER TYPE STATUS URI
solaris origin online http://10.0.7.1/
root@solaris:~# pkg install nmap
