    Installing Oracle10g (10.2.0.1) on CentOS 4.1 (RHEL AS 4 U 1)

    Actually , there are several nice articles on Oracle Technical Network
    devoted to the same topic. Whatís new may be said ?
    The target of publication is to highlight the optimal sequence of steps required to bring Oracle10g (10.2.0.1) ASM-database up on CentOS4.1 (RHEL 4 AS U1) , placing ASM instance and serviced databases in different Oracle Homes.
    Oracleasm library install is done immediately after creating "oracle" linux account and "dba" group to be ready for ASM Instance creating during the first Installer run supposed to build it. ASM instance for volumes and volumeís group management is created the first by Installer along with the volumeís group for
    database supposed to be built during the second run of Installer and to be placed into recently created volumeís group.

    1.Install CentOS 4.1
    2.Run as root:

    # groupadd dba # group of users to be granted SYSDBA system privilege
    # groupadd oinstall # group owner of Oracle files
    # useradd -c "Oracle software owner" -g oinstall -G dba oracle
    # passwd oracle
    # mkdir -p /u01/app/oracle
    # chown -R oracle.oinstall /u01
    # mkdir -p /u02/oradata/data
    # chown -R oracle.oinstall /u02

    OTN instruction:-
    Before installing Automatic Storage Management, it is recommended that you install
    the optional add-on Automatic Storage Management support library, ASMLib.
    ASMLib is an application program interface (API) Oracle that is aimed at
    simplifying the interface between the operating system and the database,
    and to exploit the capabilities and strengths of storage arrays provided by different vendors.
    ASMLib provides an alternative interface for the Automatic Storage Management-enabled
    kernel to discover and access block devices. It provides storage and operating system
    vendors the opportunity to supply extended storage-related features.
    These features provide benefits such as improved performance and greater data integrity.
    OTN instruction ends.

    3. Run as root:-

    # rpm -Uvh oracleasm-2.6.9-11.ELsmp-2.0.0-1.i686.rpm \
    oracleasmlib-2.0.0-1.i386.rpm \
    oracleasm-support-2.0.0-1.i386.rpm

    Now you get /etc/init.d/oracleasm ready to run.
    Configuring the Oracle ASM library driver.

    # /etc/init.d/oracleasm configure

    Default user to own the driver interface [oracle]: oracle
    Default group to own the driver interface [dba]: dba
    Start Oracle ASM library driver on boot (y/n) [y]: y
    Fix permissions of Oracle ASM disks on boot (y/n) [y]: y
    Writing Oracle ASM library driver configuration: [ OK ]
    Scanning system for ASM disks: [ OK ]

    # /etc/init.d/oracleasm enable

    Create ASM volumes as desired utilizing command:

    # /etc/init.d/oracleasm createdisk VLM0X /dev/sdx

    Tune /etc/sysctl.conf,/etc/security/limits.conf,/etc/pam.d/login, /etc/profile.
    and oracle's shell environment as advised in [1].
    Login as oracle:-

    $ cd /tmp/database
    $./runInstaller

    OTN instructions:-
    Itís recommended that you install Automatic Storage Management in its own Oracle home,
    regardless of whether you plan to only have one or multiple database instances.
    Installing Automatic Storage Management in its own Oracle home helps ensure higher
    availability and manageability.With separate Oracle homes, you can upgrade Automatic
    Storage Management and databases independently, and you can remove database software
    without impacting the Automatic Storage Management instance. Ensure that the Automatic
    Storage Management version is the same or later than the Oracle Database version.
    If an Automatic Storage Management installation does not already exist and you select
    the Oracle Universal Installer option to install and configure Automatic Storage Management
    only, then Oracle Universal Installer installs Automatic Storage Management in its own Oracle home.
    OTN instruction ends.
    Select " Advanced installation" and
    create ASM instance with $ORACLE_HOME=/u01/app/oracle/oracle/product/10.2.0/db_1
    Create volume group during this run .
    Exit installer.

    $./runInstaller

    Select " Advanced installation" and create new ASM-database placed into existing volume's
    group with $ORACLE_HOME=/u01/app/oracle/oracle/product/10.2.0/db_2 .
    Modify ~oracle/.bash_profile correspondently.Relogin as oracle.
    Next:-

    $ sqlplus /nolog
    SQL> conn / as sysdba
    Connected.
    SQL> shutdown immediate;
    Database closed.
    Database dismounted.
    ORACLE instance shut down.
    SQL> startup mount;
    ORACLE instance started.
    Total System Global Area 285212672 bytes
    Fixed Size 1218968 bytes
    Variable Size 88082024 bytes
    Database Buffers 188743680 bytes
    Redo Buffers 7168000 bytes
    Database mounted.
    SQL> alter database archivelog;
    Database altered.
    SQL> alter database MastDB flashback on;
    Database altered.
    SQL> alter database open;
    Database altered.

    Open Enterpise Manager console.(Enterprise Manager 10g Database Control URL
    http://ServerCentOS41:1158/em). Create new volume's group for flashback recovery area
    and modify corresponding value on Recovery Settings page of EM.
    System startup in this case should look like:-

    [oracle@ServerCentOS41 ~]$ ./lsnrstart

    Install described above was done with different Oracle Homes
    for ASM instance and ASM-database.
    To put ASM instance and ASM-database in same Oracle Home.
    Start runInstaller just once to build all stuff at a time.Login as oracle:-
    $ cd /tmp/database
    $./runInstaller

    Select " Advanced option" and install "Software only"
    in ORACLE_HOME - /u01/app/oracle/oracle/product/10.2.0/db_1.
    Modify oracle's bash_profile:-
    export ORACLE_HOME and new PATH.
    Source new bash_profile:-

    $. ~oracle/.bash_profile
    $dbca

    During this run the request to start CRS daemons by root will come up.

    # $ORACLE_HOME/bin/localconfig add

    ASM instance , needed volume's groups and ASM-database itself will be created.
    Then perform listener and local TNS names configuration.
    $netca
