Oracle VM Server 2.2 Linux Guest cannot ntp to server properly

Hi All,
I have installed a VM guest Oracle Linux Enterprise 5U6 in Oracle VM server 2.2. I follow below procedure to config NTP in VM server.
https://blogs.oracle.com/virtualization/entry/configuring_ntp_services_for_oracle
However, when I apply the NTP configuration with VM server itself on the Guest, it detects the NTP server in high jitter value. Even though the stratrum is lower than the local host, It still cannot use that server as NTP source. Here is some information about the NTP debug and IP address.
IP Address:
Oracle VM Server: 172.16.8.100
VM Guest: 172.16.8.102

Hi Avi,
Thanks for your reply. Due to we do not have Oracle VM Manager, I did configure the VM guest to point the internal NTP server (172.16.90.1) which is mapped by Oracle VM server, but the high jitter is still existed while the guest can ntpq the NTP server. Thanks.

  • Acrobat Pro XI, Server 2012 r2 Remote Desktop, cannot print until server reboot, No Pages Selected

    Ever since we migrated to terminal services (remote desktop) this problem has plagued us.
    We are a terminal services environment with 25 users.
    Our version of Adobe is 11.0.10
    I've believe I have traced the issue to temp files in \users\username\appdata\local\temp\XX
    There are [email protected] files that the system locks.
    Once those files are written out and the server locks them down the user cannot print .pdf files any longer.
    ALL OTHER APPLICATIONS WORK PERFECTLY!
    The only way to clear the situation is to reboot the server (not optimal).
    And even then the problem reappears within a day.
    I have read many different versions of this problem and tried many different solutions.
    I have tried having the users go the advanced tab when printing and choose "print as image"
    FAIL!
    I have put a acroct.ini with the following parameters in the windows directory
    [WinFntSvr]
    TTToSysPrintDisabled=1
    T1ToTTDisabled=1
    FAIL!
    I have tried to remove Microsoft security updates related to this issue and 3rd party fonts.
    FAIL!
    I've tried the "Disable Protected Mode at Startup"
    FAIL!
    I have rebuilt our print server with the latest drivers.

  • Cannot start weblogic server anymore after conf. jena for oracle database

    Hi,
    My weblogic server 10.3.4.0 installed in oracle developer days in oralce linux guest was able to start before using the oracle user account. Following the seman. tech. dev. guide, I set up jena adapter for oracle in my guest linux system. Since the oracle user doesn't have permission to copy folders into the autodeploy directory in weblogic server, so I login as root to copy the joseki.war folder into the autodeploy directory. However, after that, I am not able to start the weblogic server console anymore using the oracle user account. Any suggestions will be much appreciated. Thanks a lot in advance.

    Wrong forum - your post has nothing to do with the Oracle database. You wanted a WLS forum.

  • IPP Printing from Linux or Mac to Windows server

    I have windows server 2003 R2 ent with ipp printing installed. All windows clients are ale to connect, install and print to a shared printer via ipp. When connecting via a linux or mac machine, I am not able to print. I am asked for the creditionals to print but it does nothing.
    The ipp server is set to accept authentication via Intergrated Windows Authentication. I had read this is compatible with firefox and other browsers.
    Is there any particular settings I am missing on this one?
    The goal is to require only domain users access to the printers.

    Hi,
    Thank you for posting here.
    Since we can print from Windows clients properly, it indicates Windows Printing Server is working OK. Base on my research, we may have to setup a CUPS server so that Linux client communicate with CUPS Server and CUPS communicate with Windows Printer Server using IPP. For your reference:

    The weird thing is that ntp configuration is symmetrical between both nodes and the ntp server "193.204.114.232" does not appear in /etc/ntp.conf
    Why ntpd should use a server which is not listed in /etc/ntpd.conf ?

    Yes, that IP is a valid hostname: 193.204.114.232 is ntp1.inrim.it, the "official" italian ntp server.
    193.204.114.232 and ntp1.inrim.it do not appear in /etc/hosts, /etc/resolve.conf Ntp configuration is :

  • Oracle 9i on LINUX Transparent Gateway for SQL Server

    Does anybody know if there is a Transparent Gateway available for Oracle 9i on LINUX to connect to SQL Server? I have run the installer and cannot seem to find the install options for any Transparent Gateways. I am familiar with their location in the universal installer as I have installed the Oracle/SQL Server Transparent Gateway with Oracle in WinNT. Perhaps Transparent Gateways for Oracle/LINUX are not available?
    Thanks in advance.

    I have the same issue - we want to upgrade our 9.2 to 10g Linux, and need to maintain connectivity to some legacy sqlserver databases. I can't find any mention of tg4msql for linux. What gives? Anyone know the answer to this? thanks, michael

  • I installed Oracle database 10g on SuSE Linux Enterprise Server 8 edition.

    I installed Oracle database 10g on SuSE Linux Enterprise Server 8 edition.
    But this massage pop up when I used my browser first time before start database.
    Actually when I clicks on yes to start database.
    The web browser you are using is not optimized for this release of Oracle enterprise manager. It is recommended that you use one of the following:

  • Oracle VM 3.1.1 using Kickstart to install Linux Guests

    Up till this point in my experience with Oracle VM.... I've always used templates to create VM guests. However, I have a need to greatly customize a OEL installation and I have traditionally done this via "kickstart scripts". From what I understand, "kickstart" is not supported for installing Linux guests via PXE. If it is... I certainly can't get it to work. I have read a few things here and there about the situation but I must admit I am a little confused.
    Does anyone have any insight on how to install a Linux guest via a "kickstart" script called via PXE? If you can't use PXE, then how do you do it?
    Thanks
    Edited by: user12273962 on Jul 17, 2012 2:09 PM

    Salut,
    kickstart installations work for us. You don't say whether you're using HVM or PVM guests so I'll assume the latter.
    Note that this works for tftp and http based installation - I've not tried nfs and I seem to recall that it doesn't work for PVM systems. At present we are using exactly the same infrastructure to install VMs as for our physical systems (tftp) to keep things simple but the original tests were with http exported images.
    In the manager set the network boot path to be something like
    kernel=vmlinuz ramdisk=initrd --args="ksdevice=eth0 network bootproto=dhcp ks=http://myksserver/ks.cgi" tftp://mypxeserver/boot/RHES_5_U7_X86_64_XEN
    The kernel and ramdisk locations are relative to the URL given at the end so if you've exported the ISO then they will be a little different.
    One way to check that the first stage works is to connect to a hypervisor and run
    /usr/bin/xenpvboot <entire boot path as given above>
    If this returns something bootable then you will see
    linux (kernel /var/run/xend/boot/xenpvboot.vmlinuz.KYBNus)(ramdisk /var/run/xend/boot/xenpvboot.initrd.img.hKHQLg)(args 'ksdevice=00:16:3E:XX:XX:XX network bootproto=dhcp ks=http://myksserver/ks.cgi')

    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

    sudo /etc/init.d/oracle-mount stop
    ls /u01
    sudo /etc/init.d/oracle-mount start
    ls /u01

    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.

    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.

    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
    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}

    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

  • Error message with install of Oracle 9.2 on Mandrake Linux 9.0

    Hi,
    I hope somebody can help with this. I'm getting an error message during the installation for oracle 9.2 on mandrake linux 9. An error get thrown saying the IP address of a host cannot be determined.
    Here is what is in the log:
    *** Database Configuration Page***

    Anyone know how to resolve this error and whether or not it is very critical to the oracle installation?
    Cheers
    Johnny

    Hi johnny,
    You should first check the hosts file to see if the correct hostname and the IP address are shown. You can also check if the "hostname" command returns the correct result. If everything looks good so far, then next check if command "nslookup" returns the correct IP address. If the nslookup <hostname> command returns error, you will need to talk to the Domain Name Server (DNS) administrator to correct this network configuration problem.

  • Java connection to oracle 8.0.5 on linux

    I'm trying to run the TestInstallJDBC program off of your site
    on a RedHat Linux 5.1 box with Oracle 8.0.5 for linux installed.
    However it cannot seem to find the following classes when trying
    to import them:
    import oracle.sqlj.runtime.Oracle;
    import sqlj.runtime.ref.DefaultContext;
    How do I solve this problem?
    Do I need to download them separately from sun?
    thanks,
    there is no $ORACLE_HOME/jdbc directory on my installation, I
    think that's where it should be...

    Just to confirm for u. U should have
    $ORACLE_HOME/jdbc/lib/classes111.zip or classess102.zip. There is
    also a README there which show how to connect, sample code etc.
    If these files already installed, then i don't know what is the
    problem. U have to have these files, dirs.

  • A lot of problem for an error: Cannot start Managed Server through NM

    Hi, all. Thank for coming here.
    My main problem is cannot start Manager server through Node Manager. I've configured with the same way on my friend's network and It's works but It's wrong with mine.
    my weblogic domain:
    Machine 1: Administration Server + 1 Managed server
    Machine 2: 1 Managed server
    all of these servers communicate through SSL protocol. When I try to start Managed Server on remote machine:

    I tried to start Managed server some times again, but I face up to strange issue, this is output from console which Admin Server runs on (these exception messages throws continuously):
    +<Sep 9, 2010 12:42:53 PM EDT> <Warning> <JDBC> <BEA-001129> <Received exception while creating connection for pool "portalDataSourceNeverXA": SQL-server rejected establishment of SQL-connection. Pointbase Server may not be running on localhost at port 9093.>+

    I can ensure that all of these connection pool has configured to run on 9093 port already. Then I view the DOMAIN_NAME/pointbase.log, it said:
    Unable to start the server. start server error: java.net.BindException: Address already in use
    I cannot understand what's run on pointbase address ?
    All of these error make me angry, because I've configured with the same way on other system and It's work. I've spent all of week to fix these bug, but I'm having nothing :((
    Please help me.

    Thank Jay SenSharma.
    I've looked for these JAVA_OPTION values you said, but I cant found them. That value is content of JAVA_DEBUG option, not JAVA_OPTION. In my situation, JAVA_DEBUG=" " (it's not set by default).
    Please re-view my error log:
