How to install Oracle on openSuSE 11.3

Note: I am writing this for people who just want to install Oracle for personal use, for learning Oracle. This tutorial is not for installing Oracle for production systems or any critical use. The instructions are for 32 bit systems, it should be same for 64 bit systems but I am not sure. I am installing on openSuSe 11.3, but these steps can also work for 11.1 and 11.2, but again I am not sure 🙂

I will write down the instructions as a series of steps.
  • Step 1: Download Oracle from Oracle Website. This is a 32-bit install. For 64-bit systems download from here. You will need UserId for Oracle. You will also need to accept the license agreement. The downloaded file will be “”.

  • Step 2: Install “C/C++ Development” environment from Yast.

  • Step 3: Dwonload and install Orarun package. You will now get a User for Oracle. Open Yast(Adminsitration Settings), Select “Security and Users” tab and from there open “User Group Management”. On the resulting window set filter to “System Users”. From the list select “Oracle” and edit it. Set the password for user oracle on “User Data” tab. Go to “Deatils” tab and set the Login shell to “/bin/bash” (It will be /bin/false there). Save the changes and exit.
  • Step 4: Just some cosmetic changes, if needed. Open “/etc/profile.d/”. Check parameters ORACE_BASE, ORACLE_HOME, ORACLE_SID. You can change ORACLE_SID if you want it to be something different, by default it is “ORCL”. Modify the following parameters in “/etc/sysconfig/oracle”. [code lang=”perl”] AIO_MAX_SIZE=1048576 FILE_MAX_KERNEL=6815744 IP_LOCAL_PORT_RANGE="9000 65500" [/code] Modify the following parameters in /etc/init.d/oracle:
    test -f /proc/sys/fs/aio-max-nr && echo "  AIO_MAX_SIZE=${AIO_MAX_SIZE:-1048576}"
    test -f /proc/sys/fs/aio-max-nr && echo ${AIO_MAX_SIZE:-1048576} > /proc/sys/fs/aio-max-nr
    test -f /proc/sys/fs/aio-max-nr || echo
    You will need superuser priviliges for modifying these files.
  • Step 5: Start Oracle server.
    sudo /usr/sbin/rcoracle start
    You will get a output like:
  • Step 6: Either logg off and log in as Oracle user. Or you can Switch to Oracle user (Application Launcher -> Leave -> Switch USer). Login user id is “oracle” and use the password you hav set in Step 2. After logging inCheck some details.

  • Step 7: Unzip the download oracle installation zip file ( Step 1).
    You will now get a new directory “database”. Go to that directory and run “runInstaller” script. Before running set the execution permissions for whole database directory. Check the snapshot below:
  • Step 8: Now the oracle installer will fire up. Tick the “Create Starter Database” checkbox if you want the example databses to be installed and enter the password of your choice and click Next button. You may get a warning that directory does not exist, click OK button and move forward. Next window will be to Specify inventory localtion. This should be
    You will get a warning, click YES there. The installer will check for pre-requisites and will throw some warnings and requirements. You need to manually tick those warnings and requirements. After that hit Next button and you will be taken to “Oracle Configuration Manager Registration”. You can skip this window by hitting Next button. Now will come the summary of software which will be installed. Verify and click Next. The installation will start. The installation process will take time so be patient. After installation will finish a window will pop up giving deatils of the installation. If you want to unlock accounts and set custom password you can do it by clicking on “Password Management” here. After finishing with this, oracle will display a window which will display scrips which you need to run as root. Run the scripts and the oracle installation finishes.
Now, whenever you want to start your oracle, First fire up konsole and start Oracle service
sudo /usr/sbin/oracle start

Then become oracle user (You do not need to login from GUI as you did in Step 6, but doing it from konsole will do). Start Oracle Listner.

lsnrctl start
Now login to idle session of oracle and connect as sys and start the database.
sqlplus /nolog
Connect as sys user.
connect sys as sysdba
And start the Oracle database.

My openSuSE 11.3 Setup

After experimenting with kernel and KDE version since the release of openSuSE 11.3, I decided to have a stable system till the next SuSE release, that is till openSuSE 11.4 is released. That means no KDE 4.5 as I do not want to change anything released in SuSE 11.3. Here are a few snapshots which I took after getting everything up and running… I am sure you are going to love it 🙂
Next I am planning to migrate to ext4 from ntfs completely, but that is going to take time.

Assertive Prime Minister!

Did I hear it right! Assertive Prime Minister? Assertive Dr. Manmohan Singh? Ok.. let us first know what “assertiveness” means. As per the The Free Dictionary being “Assertive” means “Inclined to bold or confident assertion;aggressively self-assured”. So what was our dear Prime Minister “assertive” about. He was “assertive” about the thing that he can not “Shut up” his cabinet. So he is “confident” that he can not handle people who he claims to head.
On the Chinese front he says that “we” need to engage Pakistan because he has failed to counter China on Indian terms (Makes me feel once again that why are we Indians so docile, all the time.. everytime!). So our Prime Minister is “confident” that he can neither handle China nor Pakistan on Indian terms. Crux of the matter… our Prime minister is confident that he is capable of doing nothing. He has failed on Kashmir and he has failed on naxalism. In Delhi the Congress(Indira) Government says that the Naxalism is the biggest threat to national security while the cabinet minister Mamta Banerjee addresses people with PCPA (People’s Committee against Police Atrocities) “managing” the rally and the congress (Indira) “Prince” Rahul Gandhi addressing a rally in Orissa with Maoist supporters standing beside him.
I think Indians should stop getting themselves fooled by the “secular” talk of Congress(Indira), the party, whose leader, after assassination of Indira Gandhi justified the killings of Sikhs and in whose rule 5 Lakh Hindus were forced out of Kashmir. What can you expect from a party whose “assertive” Prime Minister Dr. Manmohan Singh calls in and pleaded to Yasin Malik( a former terrorist and cadre of Jammu & Kashmir Liberation front) to break his fast during the Amarnath Land dispute.

Threatning letters of Kashmir

The NEWS channels are abuzz with the letters asking Sikhs in Kashmir to either join “aazidi” movement and embrace Islam or leave Kashmir. No one in India can resonate with the chilling fear these Sikhs would have felt but for Kashmiri Hindus who went through this trauma in 1989-90. I was around eight years old when the shrill voice of loudspeakers of every mosque in Kashmir asked Kashmiri Hindus to embrace Islam or leave valley. I had already left Kashmir when a letter had arrived at my maternal home announcing that every young member in the family would be butchered if they do not leave Kashmir.
Unfortunately for us (Kashmiri Hindus), there was no media to take up the issue of what was happening to Hindus in Kashmir. Doordarshan was busy in propagating “secular” politics of the Congress(Indira) kind. While minorities where being butchered, slaughtered, disgraced and forced to leave Kashmir from every corner, the conscience of India was fast asleep in secular slumber. Unfortunately for us, Kashmiriyat died a tragic death that year.
In the years to come I would hear a lot of hair raising and spine chilling tales of absolute brutishness committed by the majority on the largest minority in Kashmir. Like, when one Kashmiri Hindu youth was shot in the knees and elbows and left to bleed in the middle of road while the “majority” entertained themselves at the death of an unarmed man. The terrorists left the man bleeding and went to drink milk in the nearby dairy shop. The man wailed and criedfor help but no one bothered. He kept bleeding until the “aazidi” seeking Kashmiri youths finished their milk came back and pumped bullets into his body to finish of the work. Needless to say, there were no protests and no agitations. Nothing mattered, because only a “Pandit” had died.
The attempt of a Kashmiri Hindu man to conceal himself in a traditional rice drum failed when these mujaheddin pumped the bullets from their AK-47 right into the rice drum. When his wailing widow asked why were they leaving her alive, the chilling answer was – “So that you can mourn his death for life”.
How much will you understand the fear of a young mother who was ready to jump off the second floor of her home with her two little daughters just to save her family from being disgraced by a mob of mad aazidi seeking hooligans who were about to break into her home…
No one heard Kashmiri Hindus then… no one will ever hear us, because “unfortunately” we do not make a vote bank. Today, Kashmiri Hindus are branded as traitors by Muslims in Kashmir because we did not support the aazidi movement. Indians will do everything and will fight to seek justice for the victims of Gujarat and Kandhamal riots, but no one will ever bother about Kashmiri Hindus, because fighting for the justice of Hindus in India is outright communal. Fighting for Kashmiri Hindus means going against the “secular” Muslims in Kashmir. Those “seculars” whose cry always has been “jeeve jeeve Paskistan, nanga bhookha Hindustan”.
Today (21th August 2010), Times NOW called a popular Kashmiri Hindu activist Aditya Raj Kaul as a panelist debating threats to Kashmiri Sikhs. But from the word go gagged him. WHY? Just because no one wants to shatter the sweet dream of “Secular” Kashmir. A dream that has already died decades ago. If people want to live in dreams, they can… But the real hard fact is – The fight for Kashmir is deeply deeply communal. The communities in Kashmir are divided… Today’s Kashmir is Kashmir where the “majority” is brandishing unashamedly its brute power and the minority is lip locked in fear, while “secular” Indians are sleeping over their conscience.
Leave alone Kashmiriyat, even Insaaniyat has died a dog’s death in Kashmir.

VIM Part II – Basic Navigation and Editing

It has been a long time since I blogged about the how to get started with VIM. So without delay I should start with basic navigation and editing in VIM. Before that I just want to say that VIM is very case sensitive (in command mode). “A” is not same as “a”. So if I type “A” it means “A” and not “a”. There are a few different modes in VIM
  • Command Mode
  • Insert Mode
  • Search mode
When you start VIM, it will be in command mode. In command mode you can move cursor, delete text, search and replace text, navigate in the file. For inserting text you will have to use “insert” mode. You will not be able to insert text in command mode. Here are the keys for basic navigation: Move Right ==> l (Small L) Move Left ==> h (Small H) Move Up ==> k (Small K) Move Down ==> j (Small J) These shortcuts are for people who want to be as fast as fast possible while typing because you do not have to break the flow of your typing with the above navigations. For people who do not like this the normal Up, Down, Right and Left arrows on their keyboards will work as well :). For inserting the text you will have to press “i” (Small I) while in command mode. After hitting “i” you will no longer be in command mode and pressing “l”, “h”, “k” and “j” will actually print these letters. In insert mode you can type in the text as you do normally. To get out of “Insert” mode, press “Esc” key. Search mode is invoked by pressing “/” in command mode. After that type for whatever you want to and hit the Return key. Press “n” (Small N) to go to next searched item and “N” (Caps N) to go to previous search item. What makes VIM an editor of choice is its command mode and the way you can navigate within it without touching mouse. Here are some commands(which I know and use): gg ==> Go to first line in the document G ==> Go the last line nG ==> Go to line number “n”. 25G takes you to the 25th line in the document. c$ ==> Chage to the end of line cw ==> Change word dd ==> delete current line ndd ==> delete next n lines where n is any number yy ==> copy current line to buffer nyy ==> copy n lines to buffer P (small) ==> paste above the line where cursor is p (caps) ==> paste below the current line where cursor is o (small) ==> Add a new line below cursor position and invoke insert mode O (caps) ==> Add a new line above cursor position and invoke insert mode The “dd” puts the deleted lines in buffer so it can be also used as cut-paste in conjuction with “p” or “P” command.
