Oracle dblink to mysql in Linux machines

Hi,
I want to make a dblink between to linux machines, one with oracle 11g database and the other with MySQL 5.0.77 database. The objective is to create triggers on a few tables in the oracle side and automatically synchronize it with same other tables in the mysql side. Can someone explain me how to accomplish this?
Thanks in advance

Hi,
To connect to MySQL from Oracle you can use the Database Gateway for ODBC (DG4ODBC). There are various notes available in My Oracle Support which give details of the setup -
Note.1083703.1 Master Note for Oracle Gateway Products
Note.466228.1 How to Setup DG4ODBC on Linux x86 32bit
Note.561033.1 How to Setup DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX)
Once you have the gateway installed and configured you can refer to MySQL tables in the triggers using the gateway database link.
However, you need to be aware that DG4ODBC does not support distributed transactions so you would need to have a commit between any Oracle updates and updates to MySQL in the trigger, so you would need to be careful about error checking.

Mike

Hi friends,
Issue : NOT able to start the Oracle Data Base 11g on Linux machine
I've successfully installed Oracle-DB-11g on my Linux machine.
Note : I haven't declared or exported any variable(s) , actually I'm not sure how and where to do this.
Can someone look into my issue , and please let me know if i have to export any variables and how/where?
Thanks

Hi;
You need to set your env. or put them in .bash_profile file

I assume you're using the "LKM file to Oracle SQL Loader".
For test purpose, can you just try with "LKM file to SQL" (slower) ?
We could check if the problem comes from the SQL Loader.
Your unix server has access to the oracle database ?

How to create dblink between oracle 10G and mysql

I want to create dblink between oracle 10G and mysql
I create it in ECC6.0 using DBCO transaction tcode,which database type can choose?Microsoft sql server?Because there have no mysql item.
I choosed MSS so that I can test it, but it failed,there is an error that 'ORA-12569:TNS:packet checksun failure'.
I configured the oracle tnsnames.ora file like this:
     CW.WORLD =
           (DESCRIPTION =
                (ADDRESS_LIST =
                      (ADDRESS =

                    (SID = XXX )
               (HS = ok )
When I tnsping CW,it will fail,like this " TNS-12569:TNS:packet checksum failure"
How can I do.

I want to know if this possible?

ORACLE DATAGUARD and STANDBY on two LINUX machine (64 bits and 32 bits)

Hi there
I have two Linux machines: one with Linux RH 4 Update 2 for 64 bits and
the other one with Linux RH 4 Update 2 for 32 bits.
I was wondering two things:
1) Is it possible to implement ORACLE DATAGUARD between these two machines?
2) Is it possible to implement only a Static Standby Database on the second node?
Suppose we have Oracle Database EE on both machines.
Thanks in advance for any information
Regards
Felipe

But both oracle database version must be of 32 bit version.
from oracle doc
2.3.1 Hardware and Operating System Requirements
The following list describes hardware and operating system requirements for using Data Guard:
All members of a Data Guard configuration must run an Oracle image that is built for the same platform.
For example, this means a Data Guard configuration with a primary database on a 32-bit Linux on Intel system can have a standby database that is configured on a 32-bit Linux on Intel system. However, a primary database on a 64-bit HP-UX system can also be configured with a standby database on a 32-bit HP-UX system, as long as both servers are running 32-bit images.

Ho do I know if an ORACLE autmatically starts up with the linux machine?

three of the machines are RAC database and there is one single node database. How do I know if the DB will automatically startup with Linux machine? and if does not automatically start how can I modify the DB's so that they will automatically start with the Linux Machine?
Thanks,
Jayanth

I assume we're talking about 11gR2.
Try the following:
ps -ef | grep ohas
In general if you use ASM you use Oracle Restart.
Here is the [url http://docs.oracle.com/cd/E11882_01/server.112/e25494/restart001.htm#ADMIN12709]documentation.
In fact it's not that complicated and if you use GUI tools (don't hate) such as asmca, netca, dbca all the components are automatically registered with Oracle Restart. If you don't then you can always use srvctl utility (same as in case of RAC) to start, stop, register, remove, check configuration of your services e.g. listener, asm, instances and much more. Actually there're a lot of similarities to Oracle Clusterware, but of cause it's just a single instance with all the simplifications that follow.
It's just very unpractical for me to type a page of text that would pretty much copy readily available documentation.
Hope it helps.

Oracle to connect MySQL

Dear All,
from couple of days I am trying to connect mysql from my oracle database.
I have studied so many documentations and have created one of my own. I am just struck at one point.
My oracle database is 11gR1 and CentOS 5.1 32-bit is the operating system.
MySQL is on a windows based machine and version is 5.1.
What I can do:
I can connect MySQL from Linux using the command: isql –v bssdata <user> <password> [Connected]
I can tnsping the listener using command: tnsping bssdata [OK]
But after setting up what i did in the documentation below when I try to connect mysql using a DB link. It gives the following error:
select * from bssdata.sta_mis_std_marks@bssdata
Error at Command Line:1 Column:40
Error report:

Hi ,
i am facing the same issue.
These are my findings at this moment.
By looking at http://www.pythian.com/news/1554/how-to-access-mysql-from-oracle-with-odbc-and-sql/ we can see that :
"Connector ODBC 5.1. The Oracle Gateway for ODBC checks/relies on some features, such as the ODBC descriptor, that are not available in 3.51. You can check the associated documentation and bug 32692 for some details about SQLSetDescRec"
So we have a bug related to SQLSetDescRec missing from the libmyodbc3.so library.
We can check this as follows :
[oracle@log]$ nm -D /usr/lib64/libmyodbc3.so | fgrep SQLMoreResults
0000000000017c70 T SQLMoreResults
[oracle@log]$ nm -D /usr/lib64/libmyodbc3.so | fgrep SQLSetEnvAttr
0000000000016c40 T SQLSetEnvAttr
[oracle@log]$ nm -D /usr/lib64/libmyodbc3.so | fgrep SQLSetDescRec
No output for SQLSetDescRec.
Now i have to see how can i get over this bug.

Problem installing Oracle 9.2 on RedHat Linux 7.1 and 9.0

Hi everyone,
As the subject line says, I tried installing Oracle 9.2 on
RedHat Linux 7.1 and 9.0, strictly following instructions
written by Werner Puschitz
(http://www.puschitz.com/InstallingOracle9i.shtml). Both
attempts failed with identical symptoms:
- the installer asks for Disk 2
- after the disk is inserted, it hangs. It turns out that
kernel is writing messages similar to these in
/var/log/messages:
Jun 16 02:45:19 boston kernel: 16:00: rw=0, want=317696, limit=149920
Jun 16 02:45:19 boston kernel: attempt to access beyond end of device
Unless interrupted, this continues until the /tmp filesystem gets full.
Has anyone experienced this? I haven't been able to find
an explanation so far.
Any help would be much appreciated.
Regards,
Ljubomir Buturovic

Providing a thread-bare configuration of your machine on which you are trying to install Oracle on Linux (and mind you - which kernel/distro, coz that's important) would definitely help you elicit more responses to your messages.

Oracle 11gR2 Express Edition on Linux Ubuntu 11.10 howto
h2. Purpose
This document outlines instructions how to install Oracle XE under Ubuntu 11.10.
Ubuntu or Debian based Linux is not on the list of supported operation systems according to the Oracle documentation at http://download.oracle.com/docs/cd/E17781_01/install.112/e18802/toc.htm. You may want to consider virtualization software like Oracle Virtualbox and install Oracle Enterprise Linux as a free and professional alternative to installing XE under Ubuntu. You can also download pre-build virtual machines that include Oracle XE. You can browse http://otn.oracle.com/community/developer-vm for more information.

h4. 11) History
h4. 12) References
h2. 1) Install Linux Ubuntu
The following assumes you have installed Ubuntu 11.10 Desktop Edition for AMD 64-bit, or upgraded from a previous version. Keep in mind that Oracle 11gR2 Express Edition is only available for 64-bit architecture. It is not necessarily a requirement, but I would not bother to install Oracle 11gR2 XE on a system with less than 2 GB of RAM installed. You can download Ubuntu for free at: http://www.ubuntu.com/download/ubuntu and install it using the default settings provided.
You can apply the latest OS patch-sets by clicking the power button icon in the upper right hand corner of the screen and selecting "Updates available..."
h2. 2) Remote Terminal
You will need command line access to perform the installation tasks. Select the top "Dash Home" button of the Unity toolbar and enter the word "terminal", or use CTRL-ALT-t. If you prefer to open a remote terminal session use SSH. Ubuntu does not come with a secure shell login by default. To install it, use the following command:
sudo apt-get install openssh-serverYou cannot login as root unless you set a root password using the "sudo passwd root" command. However, you can get root user access using the "sudo" command, which requires only to re-enter the password of your personal account. Access to "sudo" is controlled by the /etc/sudoers file.
The best way to establish a remote command line session as root is to login with your personal account, e.g.: ssh [email protected], and then type "sudo su -" to become root, or use "sudo <command>" to execute individual commands. If your account does not have "sudo" access you can login as root using "su - root", but will need to know the root password.
h2. 3) Install Additional Software
Oracle 11g Express Edition requires additional software that is not installed by default:
sudo apt-get install alien libaio1 unixodbch2. 4) Managing Swap Space
Oracle demands that the minimum swap space for Oracle Database XE is 2 GB (2095100 KB) or twice the size of RAM, whichever is lesser. Enter the following shell command to verify your swap space:
cat /proc/meminfo | grep -i swap
SwapCached:            0 kB
SwapTotal:       2095100 kB
SwapFree:        2095100 kBYou can increase available swap space by using a swap file as long as disk space permits. The advantage of a swap file versus a swap partition is flexible space management because you can add or delete swap space on demand as necessary. The following will create and enable an additional 1 GB swap file at system startup, located in the /home directory:
Login as root:
sudo su -Enter the following commands:
dd if=/dev/zero of=/home/swapfile bs=1024 count=1048576
mkswap /home/swapfile
swapon /home/swapfile
swapon -aCreate a backup of the original "fstab" file and add the new swap file:
cp /etc/fstab /etc/fstab.backup_`date +%N`
echo '/home/swapfile swap swap defaults 0 0' >> /etc/fstabExit from root and verify the new swap space:
exit
swapon -s
Filename                    Type          Size     Used     Priority
/dev/sda5                               partition     2095100     0     -1
/home/swapfile                          file          1048572     0     -2Swap space is not a substitute for installed RAM. Swap space is a safeguard that allows the system to move idle processes to disk before the OOM killer will begin to terminate processes in order to free up enough real memory to keep the system operational. The general rule for sizing the swap space depends on the size of installed RAM. If your system has less then 4 GB of RAM the swap space should usually be at least twice this size. If you have more than 8 GB of RAM installed you may consider to use an equal size as swap space. The more RAM you have installed, the less likely you are going to run into memory starvation, and the less likely you are going to need swap space, unless you have a bad process.
h2. 5) Modify Kernel Parameters
Oracle 11gR2 Express Edition requires the following Kernel parameters. Enter the commands exactly as shown:
Login as root:
sudo su -Cut & paste the following directly into a command shell (not a text editor):
cat > /etc/sysctl.d/60-oracle.conf <<-EOF
# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65500
kernel.sem=250 32000 100 128
# kernel.shmmax=429496729
kernel.shmmax=107374183
EOFLoad and verify the new kernel parameters:
service procps start
sudo sysctl -q fs.file-max
sudo sysctl -q kernel.shmmax
sudo sysctl -q net.ipv4.ip_local_port_range
sudo sysctl -q kernel.sem The SHMMAX kernel parameter defines the upper memory limit of a process. It is a safeguard to stop a bad process from using all memory and causing RAM starvation. The Linux default is 32 MB. The official Oracle XE installation documentation suggests a value of 4 GB -1 bytes (429496729). Since Oracle 11g XE has a 1 GB memory limit, a smaller footprint will be a better safeguard for the complete system. Setting the SHMMAX parameter to 107374183 will be sufficient.
h2. 6) Oracle Home Directory
At the time of this writing, Enterprise Linux 6 is not supported for Oracle database yet. It is therefore not possible to confirm Oracle ext4 filesystem compatibility, which is default in Ubuntu 11. According to various information, ext4 may cause a performance problem for Oracle 11g database. The following will show you how to add a ext3 partition to your existing setup.
h3. 6.a) Resize the Root Partition
Provided you have sufficient free disk space, you should be able to resize the root partition to create an extra ext3 filesystem. Considering the 11 GB user datafile limit of the Express Edition, 18 GB should be more than enough.
You can use the free Gparted Live CD to shrink your startup volume. Gparted downloads are available at http://sourceforge.net/projects/gparted/files/gparted-live-stable. When burning the CD, pay attention to burn the raw .iso image and not the possibly "mounted" image. If you are using a virtual machine like Oracle Virtualbox, you can mount the .iso image directly. There are going to be a few prompts when the system starts from the CD, but you can press Return to accept the defaults.
When the Gparted window appears:
- Select your ext4 root partition, usually /dev/sda1
- Select the "Resize/Move" button from the toolbar.
- Enter 18000 into the "Free space following" field and press the Return key.
Be careful not not change the start of the partition!
- Click the "Resize/Move" of the dialog and then then the "Apply" toolbar button.
The process may take several minutes - do not abandon it!
- Select the new unallocated free space of ~ 18 GB and push the "New" button.
- Set the file system to "ext3" and label it "oraclexe" and click the "Add" button.
Be sure to label it oraclexe, otherwise the follow-up instructions will fail.
- Finally select "Apply from the toolbar to apply the changes.
- Quit "Gparted", select "Exit" from the desktop and choose "Reboot" to restart the system.
{code}
After the system has restarted, open a terminal command shell.
Login as root:
{code}
sudo su -
{code}
Backup "fstab" and add the UUID of the partition. The "tr" command remove the quotes:
{code}
cp /etc/fstab /etc/fstab_`date +%N`
uuid=`blkid | grep oraclexe | awk '{print $3}'`
uuid=`echo $uuid | tr -d '\042'`
echo $uuid
echo "$uuid /u01 ext3 errors=remount-ro 0 1" >> /etc/fstab
{code}
The UUID is a unique number and should look similar to:
{code}
UUID=d1db753e-b5dd-4a4c-a61e-259c69867b58
{code}
Restart the system:
{code}
reboot
{code}
Verify the success:
{code}
df -h /u01
{code}
h3. 6.b) Setup External Storage
If you prefer to setup an external drive to install Oracle XE, beware that it can be a fatal mistake to make an entry in /etc/fstab to automount your external storage device. An unavailable device in /etc/fstab will prevent a system startup and prompt for appropriate actions at the console.
The following is an example of how to prepare an external storage device to be used for Oracle 11g, including a script to automatically mount an external drive at system startup without the disadvantages of /etc/fstab. The script will also take into consideration that a device name might shift if you attach additional devices.
To find out which USB devices are connected:
{code}
sudo parted -l
{code}
Look for the device that matches your USB storage. For example: /dev/sdb1
{code}
Model: USB 2.0 Flash Disk (scsi)
Disk /dev/sdb: 2064MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start   End     Size    File system Name     Flags
1      20.5kB 1929MB 1929MB hfs+         mystick
{code}
Initialize the device using ext3 filesystem - this will erase all data. The "-c" option will check for bad blocks (read-only), "-L" is the volume label:
{code}
sudo umount /dev/sdb1
sudo mkfs.ext3 -c -L oraclexe /dev/sdb1
{code}
Install the pmount distribution package:
{code}
sudo apt-get install pmount
{code}
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}
cat > /etc/init.d/oracle-mount <<-EOF

h2. 7) ORA-00845: MEMORY_TARGET
Oracle 11gR2 XE under Ubuntu 11.10 will result in "ORA-00845: MEMORY_TARGET not support on this system" either at Oracle database startup or during the initial installation. Ubuntu 11.10 uses a new version of the "systemd" system and session manager and has migrated away from /dev/shm and other common directories in favor of /run.
There are several ways how to address the problem. You can either enable /dev/shm shared memory, or change the default memory management of Oracle 11g from AMM (Automatic Memory Management) to ASMM (Automatic Shared Memory Management) as it was in used the previous 10g version. Since AMM is one of the new features of 11g, the following will show you how to make to make AMM work.
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}

h2. 8) Installing Oracle 11gR2 Express Edition
The final release version of Oracle 11gR2 Express Edition can be downloaded for free at http://otn.oracle.com/database/express-edition/downloads. The software should automatically downloaded into the "Downloads" folder of your home directory.
Enter the following commands to unpack the installer:
{code}
cd ~/Downloads
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
rm oracle-xe-11.2.0-1.0.x86_64.rpm.zip
{code}
The Debian Linux based package management of Ubuntu is not compatible with the Red Hat package manager. The Oracle installer needs to be converted using the following commands:
{code}
cd ~/Downloads/Disk1
sudo alien --to-deb --scripts oracle-xe-11.2.0-1.0.x86_64.rpm
(This may take a few minutes)
rm oracle-xe-11.2.0-1.0.x86_64.rpm
{code}
The following needs to be set for compatibility:
{code}
sudo ln -s /usr/bin/awk /bin/awk
sudo mkdir /var/lock/subsys
{code}
Ubuntu uses different tools to manage services and system startup scripts. The "chkconfig" tool required by the Oracle installer is not available in Ubuntu. The following will create a file to simulate the "chkconfig" tool.
Login as root:
{code}
sudo su -
{code}
Copy & paste the following *directly* into the command prompt to create a file:
{code}
cat > /sbin/chkconfig <<-EOF
#!/bin/bash
# Oracle 11gR2 XE installer chkconfig hack for Debian based Linux (by dude)

h2. 9) Post-Installation
In order to use sqlplus and other tools, the Oracle account requires specific environment variables. The following will set these variables automatically at every Oracle login:
Login as the Oracle user:
{code}
su - oracle
{code}
Copy the default account skeleton files and add the Oracle env script to .profile:
{code}
cp /etc/skel/.bash_logout ./
cp /etc/skel/.bashrc ./
cp /etc/skel/.profile ./
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
By default, the Oracle Database XE graphical user interface is only available at the local server, but not remotely. The following will enable remote logins:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and execute the following:
{code}
sqlplus / as sysdba
SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
exit
{code}
See http://download.oracle.com/docs/cd/E17781_01/admin.112/e18585/toc.htm for more information.
h3. a) Unity desktop configurations
The Oracle XE menu under the previous Gnome Classic desktop shows several useful scripts to backup the database, start and stop the database, etc. Under the Unity based desktop this menu is not available. You can either switch to the Gnome Classic desktop as outlined in chapter 2, or perform the following steps to modify and copy the scripts as outlined below. The start and stop database scripts will also be modified to perform a progress feedback.
Login as user root:
{code}
sudo su -
{code}
Convert desktop files:
{code}
cd /usr/share/applications
sed -i 's/Categories.*/Categories=Database;Office;Development;/g' oraclexe*
sed -i 's/MultipleArgs/X-MultipleArgs/g' oraclexe*
sed -i 's/MimeType.*/MimeType=application\/x-database/g' oraclexe*
sed -i 's/.png//g' oraclexe*
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-startdb.desktop
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-stopdb.desktop
{code}
Exit root:
{code}
exit
{code}
Login as user Oracle:
{code}
su - oracle
{code}
Modify database start and stop scripts:
{code}
cd /u01/app/oracle/product/11.2.0/xe/config/scripts
cp startdb.sh start.sh_orig
cp stopdb.sh stopdb.sh_orig
sed -i 's/>.*//g' startdb.sh
sed -i 's/>.*//g' stopdb.sh
{code}
You will need SYSDBA privileges and set Oracle environment variables in order to use your regular user account.
Login to your regular user account:
{code}
su - dude
{code}
Enter the folowing command:
{code}
sudo usermod -a -G dba dude
{code}
Then update your profile to automatically set the necessary Oracle environment variables:
{code}
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
Update your Desktop folder to contain useful Oracle XE scripts:
{code}
cp /usr/share/applications/oraclexe* ~/Desktop
chmod 750 ~/Desktop/oraclexe*
{code}
To verify success re-login and try "sqlplus":
{code}
su - oracle
sqlplus / as sysdba
{code}
h2. 10) Tips and Troubleshooting
h3. 10. a) Port 1521 appears to be in use by another application
Error: Port 1521 appears to be in use by another application. Specify a different port.This error happens after a previously unsuccessful configuration attempt using /etc/init.d/oracle-xe configure script. The script was able to start the Listener process, but most likely failed to continue to clone the database, e.g. ORA-00845. The following should correct the problem:
Determine the oracle listener process that is already running:
{code}
$ ps -ef | grep oracle
{code}
Your output should be similar to:
{code}
oracle   19789     1 0 19:46 ?        00:00:00 /u01/app/oracle/product/11.2.0/xe/bin/tnslsnr
{code}
Then kill the process, using the appropriate process id, for instance:
{code}
$ sudo kill -9 19789
{code}
h3. 10.b) cannot touch `/var/lock/subsys/listener': No such file or directory
Starting Oracle Net Listener...touch: cannot touch `/var/lock/subsys/listener': No such file or directoryThis error occurs when you run /etc/init.d/oracle-xe configure, but failed the preinstallation step to create the /var//lock/subsys directory as outlined in chapter 8.
h3. 10.c) ORA-00845: MEMORY_TARGET
ORA-00845: MEMORY_TARGET not supported on this system See chapter 7 to enable /dev/shm and verify free space available in /run/shm
h3. 10.d) Apex ADMIN password
According to the Oracle documentation, the password for the INTERNAL and ADMIN Oracle Application Express user accounts is initially the same as the SYS and SYSTEM administrative user accounts. Well, I tried several times without success. To reset the Apex Admin password:
Login as user oracle:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
{code}
At the SQL prompt, type the following to be prompted to change the password:
{code}
SQL> @?/apex/apxxepwd.sql
exit
{code}
When done, open your browser and go to http://127.0.0.1:8080/apex
Workspace: Internal
Username: ADMIN
Password: password you set with apxxepwd.sql
I will prompt you to reset the password:
old password: password you set with apxxepwd.sql
new password: final_password
You can also login as the Apex Admin using http://127.0.0.1:8080/apex/apex_admin
h3. 10.e) SYS and SYSTEM password
Use the following commands to reset the SYS and SYSTEM passwords if necessary:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following at the SQL prompt:
{code}
sqlplus / as sysdba
SQL> alter user sys identified by "password" account unlock;
SQL> alter user system identified by "password" account unlock;
SQL> exit
{code}
h3. 10.f) Uninstall Oracle 11g XE
The following will completely uninstall and remove Oracle 11g XE:
Open a terminal seesion and login as user root:
{code}
sudo su -
{code}
Enter the following:
{code}
/etc/init.d/oracle-xe stop
dpkg --purge oracle-xe
rm -r /u01/app
rm /etc/default/oracle-xe
update-rc.d -f oracle-xe remove
update-rc.d -f oracle-mount remove
update-rc.d -f oracle-shm remove
{code}
h3. 10.g) Reconfigure Oracle 11g XE
Type the following commands in a terminal window:
{code}
sudo /etc/init.d/oracle-xe stop
sudo rm /etc/default/oracle-xe
sudo /etc/init.d/oracle-xe configure
{code}
h3. 10.h) Gnome Classic desktop
Ubuntu 11 moved from the Gnome Classic desktop to Unity and removed the "Ubuntu Classic" login option. Unity was designed to make more efficient use of space given a limited screen size and touch screens. If you prefer to use the Gnome Classic desktop, enter the following into a terminal window:
{code}
sudo apt-get install gnome-panel
{code}
To log into the Gnome Classic desktop, select the "Gearwheel" at the login screen and select "Gnome Classic".
h3. 10.i) Unix vi cursor keys
The instructions in this tutorial do not require the use of any text editor. However, if you would like use the backspace and cursor keys in the "vi-editor", the following needs to be installed:
{code}
sudo apt-get install vim
{code}
h3. 10.j) Backup Database
In order to perform an online database backup using the supplied "Backup Database" script, the database needs to run in Archive-Log mode. This can be setup using the following commands:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
SQL> shutdown immediate
SQL> startup mount
SQL> alter database archivelog;
SQL> alter database open;
SQL> exit
{code}
h2. 11) History

Excellent Blog. Thank You
Small clarification on Step **6) Oracle Home Directory, ...a) Resize the Root Partition**
Ubuntu 11.10 has Gparted available as a Ubuntu software download, DONT use that while trying the above step, instead download the ISO file from http://sourceforge.net/projects/gparted/files/gparted-live-stable/ gparted-live-0.12.0-5.iso (124.6 MB)
Burn that ISO file on a Blank DVD, reboot the Ubuntu , during startup select Boot from DVD Option if not already selected. this will take to Boot Menu Options of Gparted Live then select the first menu option, and this allows to do further action such as Re-sizing .
and once you have chosen and executed step a) . do NOT run step b) also that is "Setup External Storage"
I hope this minor clarification can avoid some confusion

A few questions re: installing 10g on a virtual linux machine

I am in the process of building up a virtual linux box on my XP laptop and have a few questions regarding the networking setup. Purpose is to have a sandbox *nix setup at my fingertips.
Here's what I have so far:
Dell Latitude laptop running Win XP. This is a DHCP machine.
Installed VMWare Player
Created virtual machine with OEL 4.8, with NAT network config
So far, so good. Next step is to install 10.2.0.4 EE on the virtual Linux machine. When installing 10.2.0.4 directly on the XP system, of course I had to install a loopback adapter to provide a fixed IP address for Oracle, all well documented in the installation guide. While it is my understanding that the loopback adapter, as installed and configured on Windows, is primarily a Windows issue, I would expect something of the same fundamental under Linux insomuch as it is still a dhcp machine. However, when checking the relevant installation guide, the section on networking considerations and DHCP simply gave a two-paragraph discussion of what DHCP was. I found no discussion on how to deal with it in a *nix environment.
This particular vmware setup gives me a choice of 3 network configs - Bridged , NAT, or host-only (private vitrual net shared only with the host) I am currently configured to use NAT because I need outside connectivity (to yum server, etc) but do not want an additional device (ip address) on the real network. I'm guessing I could use host-only most of the time and when I need to access the internet, shut down the db and switch back to NAT.
This is all new territory for me, so I guess I'm looking at some 'best practices' advice as much as anything.

Ed,
I would encourage going for OEL 5u2 or 5u3 and including the oracle-validated package. It makes sure you have all the prerequisites for 10gR2 and makes life much easier.
I set up dozens of these machines for Oracle U classes. What I started with originally is 2 virtual NIC - a NAT and a Bridged. The Bridged allowed me to access the outside world at any time and was assigned using DHCP from the local network. The NAT I'd configure manually as a static IP, and I used it primarily to provide a second 'virtual network' so the classroom machines could communicate with each other.
In my latest iteration, I've dropped back to a single Bridged NIC based on DHCP. For Oracle install purposes, I
- pick a hostname (myhost.oraclass.com)
- switch to static IP (I've scripted it - edits /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/syscfg/network : hostname) but using the network GUI tool is ok as well
- I choose the static to macth the DHCP address assigned
- inject a single line into the /etc/hosts with the new static address, the hostname, and a hostname that I want to publish
192.168.4.21 myhost.oraclass.com orahost student21.oraclass.com student21
- set a global env variable (/etc/profile.d/oraprofile.sh (export HOSTNAME=myhost.oraclass.com)
and after installing Oracle, I switch back to DHCP. Then if I want to travel, I can easily switch the 'static' address as often as I want (also scripted) to match the IP addr the 'host DHCP' provides.
I've used the NAT. It hands out a DHCP address and usually it works for me (and Oracle) simply by making it static (as above) and letting VMWare container handle it. But every once in a while it seems to 'jam up' and I'd need to fight with it. So I've converted to bridged .. with the help of some scripts I've written.

Oracle 8.1.6 on Linux 7.0

I am trying to install Oracle 8.1.6 on Linux 7.0 on an intel machine with 256MB RAM and 512MB swap. I have religiously followed all the steps in the installation manual except changing kernel parameters and recompiling- I am not comfortable with making kernel changes and also for this test installation, I feel the default values may be sufficient.
The software is installing perfectly & at the time of database creation, it flashes an error during the initialisation phase that it is 'Not connected to Oracle'. I tried recreating the database but the same error keeps repeating.
any suggestions?

I can connect to other database in different server from the Linux machine, and I can connect to database locally. When I try to connect to the database from different machine using Oracle 8 client, the client can't establish the connection. I already started the listener. Any suggestion?<HR></BLOCKQUOTE>
I am planning to do the same (Oracle on Mandrake 7) any special notes?
Thanks.
