SQLDEVELOPER en LINUX UBUNTU

ok,I need to install Oracle SQLDEVELOPER en linux, then I went to the oracle page and was download the package for linux, but this is a .RPM file for Red Hat distribution, so I did the next: I installed "alien" package and then this was transformed in .DEB of Debian, to apply "dpkg -i install .deb" packaged this completed but I don't see for to run the aplication, someone to tell me what can I do? or another form to install this aplication, thanks in advance.

You can do a system wide search using:
find / -name sqldeveloper 2>/dev/nullRedirecting stderr to null makes the output cleaner (access to certain directories, like /proc and /root, will result in errors).

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.

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

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)

Installation completed successfully.
{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
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

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

J2SE v 1.4.2_04 SDK on Linux (ubuntu) install problem

I've seen this question posted on this forum a number of times but no-one seems to know the answer. I would love an answer to this as have already spent far too much time trying to sort it out.
I am trying to install the j2me mobile development kit: J2SE v 1.4.2_04 SDK with NetBeans 3.6 Bundle, on Linux ubuntu ...
I download the file from this site ....
I follow the instructions on the site:
I do the chmod and this works ok
I type ./j2sdk-1_4_2_04-nb-3_6-bin-linux.bin ( this is the instruction from Sun)
and then get the error message:
bash: j2sdk-1_4_2_04-nb-3_6-bin-linux.bin: command not found
What's the solution? Any ideas?
thanks

try :
sh jdkblahblhabl.bin
But there is a debian way to install it see links at http://rzr.online.fr/q/Java

Solaris Express on Linux Ubuntu (Gutsy)

I am trying to install SDXE on my VAIO laptop. It passed the compatibility tests, so there should be no problem.
But, despite I have a 12 GB primary partition available, the installer tells that there is a problem with Linux FDisk partitions, which can not coexist with Solaris FDisk partitions.
I have read that it is possible to have a multiboot computer with Solaris/Linux(Ubuntu 7.10 in my case) and Windows.
But the installer does not go further.
Or should I get rid of my Ubuntu Linux?
thanks in advance for any advice on this.

Finally, after three shots, I got Solaris in my notebook.
Now, I am struggling with WPA for my wireless network. Where does Solaris store WPA keys?
After a couple of hours, I decided to move to my router and wire my notebook :(
But it is ok. May be somebody could help me with this.
Also, is there a stand-by / hibernate option?
best regards from Lima, Peru

Silverlight dosen't work at Firefox 18.0.2 on linux ubuntu 12.10

Silverlight (Moonlight, in fact) dosen't work at Firefox 18.0.2 on linux ubuntu 12.10.

Moonlight claims to be substitue for Silverlight. Microsoft owns Silverlight who also invests in developing Moonlight using Mono for Linux is a way to hide their monopoly state, If not Moonlight should be definitely be working on Linux based OS.
It is clear that Microsoft shows we provide alternative and then if it does not work users need to switch to Windows and yes Moonlight does not work.

How to install JDK on LINUX Ubuntu on system with no net/wireless?

Hello!
I need to install JDK on LINUX Ubuntu on system with no net/wireless connection.
What are the commands?
Thank you!
Edited by: 800512 on 07:29 10/01/2011

- Download your release of choice from http://www.oracle.com/technetwork/java/javase/downloads/index.html
- Put the file on a USB thumb drive
- Mount that drive on the target machine
- Follow the installation instructions.
The Linux/Ubuntu downloads of the JDK are offline installers (i.e. the downloaded file contains everything that's required). Only Windows currently has an online installer (smaller initial download, but requires a net connection for the actual installation)
Alternatively: install the OpenJDK from the official Ubuntu packages using apt-zip (http://wiki.debian.org/AptZip).

Linux ubuntu firefox 3.6 fonts

I have mentioned last time the firefox fonts problem in linux ubuntu.
Now i have the proof !
I already follow many fonts setting instructions via forums but it still the same.
This is the only reason i switch to chromium, google chrome.
http://img442.imageshack.us/img442/7126/70196238.png
Note: view this images in "fit view"
== This happened ==
Every time Firefox opened
== User Agent ==
Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/5.0.342.9 Safari/533.2

I just upgraded to Kubuntu 10.04 and I immediately noticed how cruddy the text looked in Firefox. Here's something I found that seems to help.
Go to System Settings > Fonts
Enable "Use anti-aliasing", then click on the "Configure" button. A
pop-up window comes up titled "Configure anti-aliasing settings," and click in the box for "Use sub-pixel renderings"; next to that, in the drop-down window, I chose RGB. I left "Hinting Style" at "Medium."
I don't know all the details, but these settings use the color sub-pixels to smooth out the font appearance. Good enough for me, at any rate.

Installing SQL Server 2012 on Linux Ubuntu

Hello, Can I install SQL Server 2012 on Linux Ubuntu? So far I can only find downloads of ODBC for Red Hat. Any ideas?

Problem with Site Studio sites unde Linux - Ubuntu 9.10

Hello all,
I installed UCM under Linux (Ubuntu 9.10). As part of the setup I configured the installed Apache server by adding to apache2.conf:
LoadModule IdcApacheAuth /opt/oracle/ucm/server/shared/os/linux/lib/IdcApache22Auth.so
IdcUserDB idc "/opt/oracle/ucm/server/data/users/userdb.txt"
Alias /idc "/opt/oracle/ucm/server/weblayout"
<Location /idc>
Order allow,deny
Allow from all
DirectoryIndex portal.htm index.htm
IdcSecurity idc
</Location>
UCM interface works as expected and all was working ok.
I then followed the Site Studio Tutorial Setup Guide and added some lines to the apache2.conf and it now looks like:
LoadModule IdcApacheAuth /opt/oracle/ucm/server/shared/os/linux/lib/IdcApache22Auth.so
IdcUserDB idc "/opt/oracle/ucm/server/data/users/userdb.txt"
Alias /idc "/opt/oracle/ucm/server/weblayout"
<Location /idc>
Order allow,deny
Allow from all
DirectoryIndex portal.htm index.htm
IdcSecurity idc
</Location>
UseCanonicalName off
<Location "/">
IdcSecurity idc
</Location>
Afterwards I installed the Ravenna Hosting Tutorial. It appears ok in the site studio configuration pages. But when I try to view the site I get a 404. In apache access.log I see:
172.18.0.160 - - [01/Mar/2010:10:25:58 +0000] "GET /RVH/index.htm HTTP/1.1" 404 499 "http://ucm/idc/idcplg?IdcService=SS_GET_SITES_ADMIN_PAGE" "Mozilla/5.0 (Windows; U; Windows NT 6.0; pt-PT; rv:1.9.2) Gecko/20100115 Firefox/3.6 GTB5 (.NET CLR 3.5.30729) WIT Toolbar 2.0.17 for Firefox"
And in error.log I have:
[Mon Mar 01 10:28:05 2010] [error] [client 172.18.0.160] File does not exist: /var/www/RVH, referer: http://ucm/idc/idcplg?IdcService=SS_GET_SITES_ADMIN_PAGE
Can someone give me a hand at what I'm doing wrong?

Managed to solve this.
The problem was with SSUrlMapPlugin.so not being loaded because of a missing dependency in the OS. I had to install libstdc++2.10-glibc2.2_2.95.4-24_i386.deb that is no longer on the Ubuntu 9.10 repositories so one has to fetch it from older releases.
wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gcc-2.95/libstdc++2.10-glibc2.2_2.95.4-24_i386.deb
dpkg -i libstdc++2.10-glibc2.2_2.95.4-24_i386.deb
And then restart apache and the content server.
