    Installing Oracle 9iR2 on Redhat 9

    Part I

    Ok people so here goes...

    Pre-Installation Checks

    [1] OS : Redhat 9 (latest updated version from the RHN, _27.9)
    [2] Software : Oracle 9iR2 database from otn.oracle.com. Go to downloads and download it.(to preferably /tmp directory, make sure you have enough space in it as you will be copying/and unzipping it to your local HDA)

    [3] Make sure you have enough hard disk space. (I'll say keep it 5 G just in case, although 3.5G in ok).

    [4] Powerful machine? I don't know about tht. I have a chevo laptop 40G diskspace(RH9 uses 10G), 1G mem, 600MB swap space. So I am way above the specs. but a min of 500mb swap space. Oracle recommends a swap partition of either 400 megabytes or twice the amount of your RAM, whichever is greater.
    [5] Oracle is not certified to run on Redhat 9 so I assume you're doing all that for development/curiosity/learning(I'm doing it to learn linux better heh)

    So we're ready to go?

    Step 1:(I've also carried out steps in different orders, yep I know, it ain't windoos, you can do things in varienty of ways)

    Make users and Groups(These at a minimum, I've seen more groups being made)

    [root@cc345772-a root]# groupadd dba
    [root@cc345772-a root]# groupadd oinstall
    [root@cc345772-a root]# useradd -g oinstall -G dba oracle
    [root@cc345772-a root]# passwd oracle
    here you'll be prompted for a pwd, punch it twice in and you're done with this part.

    Step 2 : Creating directories, I want to go the OFA way so I made 6 directories, just doing it by the book
    [root@cc345772-a root]# mkdir /u01 /u02 /u03 /u04 /u05 /u06
    [root@cc345772-a root]# chown oracle.dba /u01 /u02 /u03 /u04 /u05 /u06
    [root@cc345772-a root]# chmod 775 /u01 /u02 /u03 /u04 /u05 /u06
    [root@cc345772-a root]#
    Step 3 : Downloading/Unzipping etc

    OK If you haven't downloaded oracle 9iR2 do so from the oracle website http://otn.oracle.com/software/produ...linuxsoft.html

    [root@cc345772-a root]# cd /tmp/9i
    [root@cc345772-a 9i]# -- Here I've created new directory and gave oracle user as well all the rights(you might encounter errors when you start installation while logged on as
    user oracle , linking of files gave me errors at the end of it)

    This way you avoid the gunzip/ then cpio command. in one go,
    [root@cc345772-a 9i]# zcat lnx_920_disk1.cpio.gz | cpio -idmv
    [root@cc345772-a 9i]# zcat lnx_920_disk2.cpio.gz | cpio -idmv
    [root@cc345772-a 9i]# zcat lnx_920_disk3.cpio.gz | cpio -idmv
    Or gunzip it,
    gunzip lnx_920_disk1.cpio.gz lnx_920_disk2.cpio.gz lnx_920_disk3.cpio.gz 
    # and then unpack it...
    cpio -idmv < lnx_920_disk1.cpio
    cpio -idmv < lnx_920_disk2.cpio 
    cpio -idmv < lnx_920_disk3.cpio
    Then you have Disk1, Disk2 and Disk3 respectively ready for you.(Which ever way you chose).

    Step4: Tools and Libraries for backward compatibility?

    Well I've seen people suggesting this for backward compatibility.
    I did this to check what I have on my hand...
    [root@cc345772-a root]# rpm -q gcc cpp compat-libstdc++ glibc-devel kernel-headers binutils
    package kernel-headers is not installed
    [root@cc345772-a root]#
    As you can see I don't have it all but it didn't make much of a difference with the installation.

    Anyways check it up and you can always install them if you don't have it from your shrike disk3. With redhat 9 you can do it withthe GUI.

    Start menu->System Settings->Add/Remove Applications, or from the command line, using:

    rpm -Uvh

    Step5: Tuning kernel parameters

    Append these to the /etc/sysctl.conf...
    kernel.shmmax = 536870912
    kernel.shmmni = 4096
    kernel.shmall = 2097152
    kernel.sem    = 250 32000 100 128
    fs.file-max   = 65536
    net.ipv4.ip_local_port_range = 1024 65000

    append these lines to /etc/security/limits.conf
    oracle soft nofile 65536
    oracle hard nofile 65536
    oracle soft nproc 16384
    oracle hard nproc 16384
    Then you can reboot to let the changes take effect , If you can't then do this to change kernel parameters at runtime...
    [root@cc345772-a root]# echo 250 32000 100 128 > /proc/sys/kernel/sem
    [root@cc345772-a root]# echo 536870912 > /proc/sys/kernel/shmmax
    [root@cc345772-a root]# echo 4096 > /proc/sys/kernel/shmmni
    [root@cc345772-a root]# echo 2097152 > /proc/sys/kernel/shmall
    [root@cc345772-a root]# echo 65536 > /proc/sys/fs/file-max
    [root@cc345772-a root]# echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range
    Step6: Setting up env variables for user oracle

    Now login as oracle user

    su - oracle

    append these lines to the .bash_profile
    # oracle 9i
    export ORACLE_BASE=/u01/ora92 -- your file locations
    export ORACLE_HOME=/u01/ora92/product/9.2 
    export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin:$PATH
    # -- NO NEED TO DO ANY OF THE JRE/JDK(more on that later)
    export ORACLE_OWNER=oracle
    export ORACLE_SID=nick920 
    # -- Your own sid
    export ORACLE_TERM=xterm
    # Use old Linuxthreads with floating stacks instead of
    # the new Native POSIX Thread Library (NPTL)
    export LD_ASSUME_KERNEL=2.4.1
    export THREADS_FLAG=native
    # Edit paths
    export LD_LIBRARY_PATH=/opt/ora9/product/9.2/lib:$LD_LIBRARY_PATH
    export PATH=/opt/ora9/product/9.2/bin:$PATH
    export SQLPATH=$ORACLE_HOME/dbs
    # change this NLS settings to suit your country:
    # example:
    # german_germany.we8iso8859p15, american_america.we8iso8859p2 etc.
    # BTW you don't need to append it wth the .we8iso8859p2, if you're not sure, otherwise you may get trouble while creating the db or even logging into sqlplus etc.(if you
    export NLS_LANG='american_america'

    Step7: You can set up temporary swap space logged is as ROOT.

    % dd if=/dev/zero of=tmp_swap bs=1k count=900000
    % chmod 600 tmp_swap
    % mkswap tmp_swap
    % swapon tmp_swap
    And then free it (I didn't need it as I had enough of it)
    % swapoff tmp_swap
    % rm tmp_swap
    log off as oracle user to let the env variables take effect.

    Check then after logging as...
    [oracle@cc345772-a oracle]$ env | grep ORACLE
    [oracle@cc345772-a oracle]$
    PS: About the JDK/JRE , there is no need to install it seperately as oracle has it's own jre , unless you want to setup the startup of listener, database(s), agent, http server,
    you might want to download a rpm from http://www.gurulabs.com/downloads.We'll come to that later. For dbca, oemapp(enterprize manager stuff like that), I'll say, NO NEED.

    Oracle installer must run from X and in order to let oracle user to be able to write to X do...
    $ xhost +
    (Again I didn't do it as I am doing it from X)

    Continued on Part II...
