Oracle 9i Express

Hi all,
Could anyone tell me where i could download a version of Oracle 9i Express edition. The free edition for home users and students. The Oracle website seems to only provide the 10g version for Express edition and i am more used to 9i.
Thanks in advance

10g was the first version with Express edition.
If you need it just for self educational purposes you can download any other (enterprise or standard edition)

  • Can not login to Oracle Application Express after upgrade to 3.2

    I installed oracle database express and then I upgrade APEX to 3.2 on it. I got the login page but I can not login by using any account, like SYS, SYSTEM. From the document, internal ADMIN account should exist but I did not see it from dba_users table.
    Thanks,
    Julie

    HI Don,
    I did run apxchpwd.sql to change the Application Express ADMIN user password. Then I invoked http://mymachine:8080/apex and got the Application Express login page. I put ADMIN in workspace and ADMIN in Username and the new password. But I still cannot login. I also tried http://mymachine:8080/apex/apex_admin page login. I typed ADMIN as username and the new password. Then I clicked on Login button. Nothing happened. No error message.
    Any idea?
    By the way, what does apxxepwd.sql do?
    Thanks,
    Julie

    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. 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
    #! /bin/sh
    # /etc/init.d/oracle-mount

        else
           rm -f \$VOL_SYMLINK

    uuid=`blkid | grep oraclexe | awk '{print $3}'`
    echo $uuid
    sed -i "s/^VOL_UUID=.*/VOL_$uuid/g" /etc/init.d/oracle-mount
    {code}
    The UUID of your device will be a unique number, but should be similar to:
    {code}
    UUID="3f5e9963-b328-49f3-b3e8-a3561ae34106"
    {code}
    Logout of root and test the init script:
    {code}
    exit
    sudo /etc/init.d/oracle-mount stop
    ls /u01
    sudo /etc/init.d/oracle-mount start
    ls /u01
    {code}

    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 -

    The upper limit of shared memory under Linux is set to 50 % of the installed RAM by default. If your system has less than 2 GB of RAM installed, there is still a chance to run into ORA-00845 error if your shared memory is used by other software.
    The verify available shared memory, type the following commands:
    {code}
    sudo df -h /run/shm
    {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)
    # Only run once.

    Run the configuration script to create (clone) the database and follow the screen. Accept the default answers, including "y" to startup the database automatically, or modify as required.
    {code}
    sudo /etc/init.d/oracle-xe configure
    (This can take a few minutes - the installation completed successfully.)
    {code}
    To verify success, the procedure should end showing:
    {code}

    Set a password for the Oracle account:
    {code}
    sudo passwd oracle
    {code}
    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

    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}

    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

    Minimum swap space required is 2 GB. You can increase swap space if necessary using a swap file:
    To analyze current swap space and memory configuration:
    sudo cat /proc/meminfo
    To install a 1 GB swapfile named swapfile in /, for example:
    sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576
    (this may take a while)
    sudo mkswap /swapfile
    sudo swapon /swapfile
    sudo cp /etc/fstab /etc/fstab.orig
    sudo echo '/swapfile swap swap defaults 0 0' >> /etc/fstab
    Verify:
    sudo swapon -a
    sudo swapon -sh4. A.4. Kernel Parameters
    Oracle 11g XE requires the following additional kernel parameters:
    sudo nano /etc/sysctl.d/60-oracle.conf
    (Enter the following)
    # Oracle 11g XE kernel parameters
    fs.file-max=6815744
    net.ipv4.ip_local_port_range=9000 65000
    kernel.sem=250 32000 100 128
    kernel.shmmax=536870912
    (Save the file)
    Note: kernel.shmmax = max possible value, e.g. size of physical RAM.
    Verify: sudo cat /etc/sysctl.d/60-oracle.conf
    Load new kernel parameters:
    sudo service procps start
    Verify:
    sudo sysctl -q fs.file-max
    -> fs.file-max = 6815744h4. A.5. Oracle Installation Directory
    The current Oracle Installation Guide uses the same directory like in previous versions: /usr/lib/oracle/xe/app/oracle/product/11.2.0/server. However, the current Beta installation uses Oracle Flexible Architecture (OFA) and installs into /u01/app/oracle/product/11.2.0/xe. Due to size limitations of Oracle XE it may not be necessary to store the installation to a specific directory or separate volume, but it is possible:
    Install Oracle XE to separate disk volume:
    From the system console menu: System > Administration > Disk Utility
    Select "ext3" filesystem for Oracle compatibility and specify a Volume label, e.g. Oracle.
    Notice the device name e.g. /dev/sdb
    Get the drive UUID:
    sudo blkid
    e.g. /dev/sdb: UUID="d19a2d8f-da43-4802-8bdb-0703c855e23a"
    Modify /etc/fstab to automatically mount the volume at system startup:
    sudo cp /etc/fstab /etc/fstab.original
    sudo nano /etc/fstab
    (Add the following, using determined UUID, for exmple)
    UUID=d19a2d8f-da43-4802-8bdb-0703c855e23a /u01 ext3 defaults,errors=remount-ro 0 1
    (Save the file)
    Create the mount-point, mount the new volume and set ownership and privileges:
    sudo mkdir /u01
    sudo mount -a
    sudo chown root:root /u01
    sudo chmod 755 /u01
    Verify:
    df -h
    or restart the systemYou can also install Oracle XE into a specific directory:
    Create a symbolic link to store the installation into an existing directory, for instance:
    sudo mkdir /home/oracle-xe
    sudo ln -s /home/oracle-xe /u01h3. C) Oracle 11g XE Download and Installation
    h4. C.1. Download and convert the Installer from Red Hat to Ubuntu
    Please see section E.3. to download the Oracle 11gR2 XE installer.
    Select the version listed for Linux x64.
    sudo unzip linux.x64_11gR2_OracleXE.zip
    sudo alien --to-deb --scripts oracle-xe-11.2.0-0.5.x86_64.rpm
    (This may take a while)h4. C.2. Create a special chkconfig script
    The Red Hat based installer of Oracle XE 11gR2 beta relies on +/sbin/chkconfig+, which is not used in Ubuntu. The chkconfig package available for the current version of Ubuntu produces errors and my not be safe to use. Below is a simple trick to get around the problem and install Oracle XE successfully:
    Create /sbin/chconfig:
    sudo nano /sbin/chkconfig
    (Cut and paste the following)
    #!/bin/bash
    # Oracle 11gR2 XE installer chkconfig hack for Debian by Dude
    file=/etc/init.d/oracle-xe
    if [[ ! `tail -n1 $file | grep INIT` ]]; then
       echo >> $file
       echo '### BEGIN INIT INFO' >> $file
       echo '# Provides:             OracleXE' >> $file
       echo '# Required-Start:       $remote_fs $syslog' >> $file
       echo '# Required-Stop:        $remote_fs $syslog' >> $file
       echo '# Default-Start:        2 3 4 5' >> $file
       echo '# Default-Stop:         0 1 6' >> $file
       echo '# Short-Description:    Oracle 11g Express Edition' >> $file
       echo '### END INIT INFO' >> $file
    fi
    update-rc.d oracle-xe defaults 80 01
    (Save the file)
    Set appropriate execute privileges:
    chmod 755 /sbin/chkconfig
    Note: You should remove the /sbin/chkconfig file after successful installation of Oracle XE.
    h4. C.3. Install and configure Oracle XE
    sudo dpkg --install ./oracle-xe_11.2.0-1.5_amd64.deb
    /etc/init.d/oracle-xe configure
    (This will take a while)
    Remove the /sbin/chkconfig script, which is no longer needed.
    sudo rm /sbin/chkconfigh4. C.4. Relocate and Configure the Oracle user login
    The Oracle XE installer specifies /u01/app/oracle as the login directory for the Oracle user. Although not really necessary, the following will relocate the Oracle user $HOME to a standard location and create standard /etc/skel login files:
    Exit all Oracle user sessions:
    sudo /etc/init.d/oracle-xe stop
    sudo kill -9 `ps -ef | grep oracle | grep -v grep | awk '{print $2}'`
    sudo userdel oracle
    sudo useradd -s /bin/bash -G dba -g dba -m oracle
    sudo passwd oracle
    Verify:
    sudo id oracle
    -> uid=1001(oracle) gid=1001(dba) groups=1001(dba)h4. C.5. Setup Oracle environment variables
    In order to use sqlplus and other tools, the Oracle account requires certain environment variables. The following will set these variables automatically at every interactive Oracle login:
    sudo echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >> /home/oracle/.bashrch4. C.6. Oracle sudo root access
    It is not essential to allow the Oracle user to use sudo, but it is convenient:
    usermod -G admin oracle
    Verify:
    id oracle
    -> uid=1001(oracle) gid=1001(dba) groups=1001(dba),120(admin)
    sudo su -
    -> Enter Oracle account passwordh4. C.7. Oracle 11g XE Post-installation
    After you install Oracle Database XE, its graphical user interface is only available from the local server, but not remotely.
    The following will correct the problem if necessary:
    Login as user Oracle or use:
    su - oracle
    sqlplus / as sysdba
    At the SQL prompt, enter the following command:
    EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
    exith3. D) Unintstall, Reconfigure and Troubleshooting
    h4. D.1. Uninstall Oracle 11g XE
    The following will completely uninstall and remove Oracle 11g XE:
    Login as user root:
    sudo su -
    /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 removeh4. D.2. Reconfigure Oracle 11g XE
    Type the following in a terminal window:
    /etc/init.d/oracle-xe stop
    sudo rm /etc/default/oracle-xe
    /etc/init.d/oracle-xe configureh4. D.3. Enable Archivelog mode and perform a database backup
    Login as user Oracle:
    su - oracle
    sqlplus / as sysdba
    At the SQL prompt, enter the following commands:
    shutdown immediate
    startup mount
    alter database archivelog;
    alter database open;
    exit
    Login to system console of the Oracle user account:
    Select Applications > Oracle Database 11g Express Edition > Backup Databaseh3. E) Notes

    ... in progress
    Regards and best of luck!
    Edited by: Dude on May 25, Version B: various corrections. chkconfig package (A.2.) not required.

    even though I am admin user.Admin user is a MS Windows term, that does not apply to Linux or Unix in the same fashion.
    The configuration script tells you "You must be root user to run the configure script. Login as root user and
    then run the configure script."
    This is most likely correct because your account is not root and does not have UID 0. What you can do is to login as root e.g. sudo su -, as the message suggest, or use "sudo /etc/init.d/oracle-xe configure", provided your account is defined in the /etc/sudoers file to perform root/admin actions.
    Btw, do not modify /etc/passwd and /etc/group to give you admin privileges or try to create a another root account under a different name. That's not the way it works and usually leads to nasty problems.

  • "Problem with links in Oracle 10g Express Edition Application Interface"

    Hi.
    Under Object_Interface>Browse>Procedure the "edit" and "compile" links are not working.Also I am unable to see my code when I click on one of the procedures. Kindly help me out.
    Thanks & Regards
    Sri

    My laptop didn't start this morning. Can you help me out?
    (Go to the Express Edition forum at Oracle Database Express Edition (XE) and give them some hints about what the problem is. )
    At the very least you will need to tell people: operating system, browser, whether you have Firewall turned on, whether you are using anti0virus, whether yo have upgraded the Application Express interface.
    You can volunteer that information, or you can wait until people ask for it, but you will need to provide that information. And if you force people to ask - it's quite likely they will get bored with your problem.

  • Unable Logging in to Oracle Application Express Administration Services

    I am new for DB. Installed Oracle XE, followed the instruction "Logging in to Oracle Application Express Administration Services", I can not find the login page:
    http://127.0.0.1:7777/pls/apex/apex_admin
    I work on the PC in which XE installed.
    Where are these two files
    ORACLE_BASE\ORACLE_HOME\install\portlist.ini
    ORACLE_BASE\ORACLE_HOME\Apache\Apache\conf\httpd.conf
    I did a search, can't find them.
    Any help welcome.
    Thanks.

    The default port for the Apex webserver is 8080, not 7777.
    To access the XE Database GUI from the Start menu, select Programs (or All Programs), then Oracle Database 10g Express Edition, and then Go to Database Home Page. (I'm assuming your on Windows)
    Or try: http://localhost:8080/apex in your browser.
    The files you mention relate to Apache web server. Oracle XE does not include a Apache, it's web server is built into the database. Are you sure you're following the right documentation? See http://www.oracle.com/pls/xe102/homepage
    Hope this helps.

  • Need help on installing Oracle Application express 3.2

    Hi,
    I had downloaded Oracle 11g database and installed the personal edition.I got the Enterprise manager login page working and also the DBConsole
    I had Downloaded APEX 3.2 and wanted to install apex 3.2.I wanted to do the following scenario
    Scenario 3: Install from the Database and Configure the Embedded PL/SQL
    Gateway
    Planning to do these steps: ( I have few questions on these steps and are below each step)
    ■ Running the apxconf.sql Configuration Script
    Do I have to install Oracle Application express or is it already installed in 11g personal edition?
    Do I have to create a seperate database or schema for this step( I have only one instance orcl1) ?■ Verifying the Oracle XML DB HTTP Server Port
    Can I do this step in my current orcl1 instance,if so which user■ Enabling Oracle XML DB HTTP Server
    Once I carry out these steps, Can I access the admin page for apex with https://localhost:port/apex_admin ?
    Am I missing any other steps ?
    Thanks

    I have one idea..
    Try to install again:
    1) download and unzip apex_3.2 in $ORACLE_HOME
    You will have:
    $ORACLE_HOME/apex - old directory
    $ORACLE_HOME/apex_3.2 - new directory
    2) in command line go to $ORACLE_HOME/apex_3.2/apex
    run sqlplus "/as sysdba"
    in sqlplus run @apexins tablespace_apex tablespace_files tablespace_temp images
    Where:
    tablespace_apex is the name of the tablespace for the Oracle Application Express application user.
    tablespace_files is the name of the tablespace for the Oracle Application Express files user.
    tablespace_temp is the name of the temporary tablespace.
    images is the virtual directory for Oracle Application Express images. To support future Oracle Application Express upgrades, define the virtual image directory as /i/.
    Example:
    @apexins SYSAUX SYSAUX TEMP /i/
    3) check installation log for errors
    4) in command line go to $ORACLE_HOME/apex_3.2/apex
    run sqlplus "/as sysdba"
    in sqlplus run @apxconf
    set admin password
    set port
    5) run @apxldimg.sql $ORACLE_HOME/apex_3.2
    6) check for running listener and try to login apex: http:\\host:port\apex\apex_admin
    Good luck!

  • How do I create "Oracle Application Express Adminstrator" in APEX 3.2.1?

    Hello,
    Quite the newbie so I appreciate any assistance with this.
    How do create "Oracle Application Express Adminstrator" in APEX 3.2.1? I am not talking about a workspace adminstrator but an Entire APEX instance administrator or "superuser"?
    I log into APEX_ADMIN as ADMIN and understand how to create a new user. But how do I grant the new user DBA or "super user" privlidges? It was easy to do when I first installed XE, I would just "check" the "DBA" when I created the user. But when I upgraded to APEX 3.2.1 the function does not seem to be there?
    Thank you for any help you can provide!

    Hi,
    I think you can not grant DBA role from Apex anymore.
    You need connect to database e.g. with SYS user and grant that role.

    yaa i'm sure about that .
    i want one more instance of database.Can you perhaps explain why? I have a fair share of production and development servers - and not a single one of them needs to run more than one database instance.
    So I'm interested in what requirement you are trying to satisfy by using two database instances on a single platform.
    Oh yeah - if you want to create a custom XE instance (different SID, different tablespace sizes, more/less PL/SQL stuff installed, hack standard), make a copy of your XE db creation script (in your XE's +$ORACLE_HOME/bin+ and called createdb.sh ) and modify that for your needs.
    PS. even with a different SID, only a single XE instance can be run at a time - you can however have 2 different ones defined and then use one at a time (e.g. testing international settings, init param differences, etc.)

    I only see the following folders after install, which tells me that although the program shows up in program and features, it is still not successfully installed?

    It looks like you will have to uninstall "libaio1", but I don't know for sure and don't have Ubuntu 10.4 available right now to play with.
    Sorry but the instructions are for Ubuntu 10.10, not 10.4, which is different.
    If you need to install XE on Ubuntu, I'd rather suggest 11gR2 XE:
