Make local yum repository

- run mount command to mount repo file :
ex: mount -t iso9660 -o loop /dev/hdc /u02
- go to yum repo directory
cd /etc/yum.repos.d
- make file local.repo in this directory
insert below script in local.repo
[localrepo]
name=My local repo
baseurl=file:///u02/Server
enabled=1
gpgcheck=0
#gpgkey=file:///path/to/you/RPM-GPG-KEY
- run df -h to check the repo file already mounted

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 3.8G 1.8G 1.9G 50% /
tmpfs 494M 0 494M 0% /dev/shm
/dev/hdc 2.9G 2.9G 0 100% /u02

Extend swap space on linux

Actually, yes. You can supplement your swap partition with a swap file. It goes something like this:

First, create a large empty file:
Code:
sudo dd if=/dev/zero of=/swap_file bs=1M count=1000
Replace 1000 with the size of the swap file desired, in MB. You can also put the swap_file in a different location if desired.


Next, we'll secure the swapspace, so ordinary users cannot read the contents (potential security breach):
Code:
sudo chown root:root /swap_file
sudo chmod 600 /swap_file
Then, turn it into swap space:

Code:
sudo mkswap /swap_file
Next, turn it on:
Code:
sudo swapon /swap_file

To make it turn on at every bootup, open up /etc/fstab:
Code:
sudo gedit /etc/fstab
Add this line to the end of the file:
Code:
/swap_file none swap sw 0 0

kemudian paket yang diperlukan:

• libaio_0.3.104-1_i386 –> http://oss.oracle.com/debian/dists/unstable/main/binary-i386/libaio_0.3.104-1_i386.deb

• libaio1_0.3.104 –> http://rpm.rutgers.edu/repository/ubuntu/pool/main/liba/libaio/libaio1_0.3.104-1ubuntu6_i386.deb

install kedua libaio setelah itu install oracle-xe

dpkg -i libaio_0.3.104-1_i386.deb

dpkg -i libaio1_0.3.104-1ubuntu6_i386.deb

dpkg -i oracle-xe_10.2.0.1-1.1_i386.deb

kemudian jalankan

masih dalam konsole

export PATH=$PATH:/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin

export ORACLE_HOME=”/usr/lib/oracle/xe/app/oracle/product/10.2.0/server”

export ORACLE_SID=XE

kalo tahap ini sudah selesai, silahkan test oraclenya

kalo sudah masuk berarti sudah sukses

How To Read ISO File in Linux

1. Login with root user ID
2. Create a directory to serve as mount point. You may also skip the directory creation by using default directory that created during Linux installation (e.g. /media/cdrom or /mnt/cdrom in some Red Hat Linux editions).
3. Suppose you want to mount /ISO/rhel4-cd1.iso image file to /media/cdrom directory mount point, execute this mount command

mount -o loop -t iso9660 /ISO/rhel4-cd1.iso /media/cdrom

4. Now, you can read / access the CD image file that is mounted to /media/cdrom directory, as if you’re accessing the physical CD-ROM loaded into hardware drive.

5. To un-mount the loaded CD image file, simply execute
umount /media/cdrom or eject /media/cdrom command will do.
