Installing Oracle and Blackboard on Centos

This is a guide for creating a Development installation using Centos. If you want to create a production instance of Blackboard, please refer to the official Blackboard documentation.
  1. Install latest Centos on a machine (6.2 x86_64)
  2. vi /etc/yum/pluginconf.d/fastestmirror.conf 
    include_only=mirror.aarnet.edu.au
  3. yum update ; reboot
  4. vi /etc/sysconfig/iptables 
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 2222 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1521 -j ACCEPT
  5. /etc/init.d/iptables restart
  6. chkconfig --level 2345 sshd on #enable sshd at startup
  7. vi /etc/sysctl.conf 
    fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586
  8. vi /etc/security/limits.conf 
    oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240
  9. Install necessary packages 
    yum install binutils compat-libcap1 compat-libstdc++-33 elfutils-libelf-devel elfutils-libelf gcc-c++ gcc glibc glibc-common glibc-devel glibc-headers ksh libaio-devel libaio libgcc libstdc++-devel libstdc++ make nss-softokn freebl numactl-devel sysstat unixODBC unixODBC-devel
  10. Create groups and users 
    groupadd -g 501 oinstall
groupadd -g 502 dba
groupadd -g 503 oper
groupadd -g 504 asmadmin
groupadd -g 506 asmdba
groupadd -g 505 asmoper
useradd -u 502 -g oinstall -G dba,asmdba,oper oracle
passwd oracle
useradd bbuser
passwd bbuser
  11. vi /etc/selinux/config 
    SELINUX=disabled
  12. Reboot
  13. Log in as oracle
  14. vi .bash_profile 
    # Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=localhost.localdomain; export ORACLE_HOSTNAME
ORACLE_UNQNAME=bb9; export ORACLE_UNQNAME
ORACLE_BASE=/home/oracle/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=bb9; export ORACLE_SID
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
  15. Reboot
  16. Install Oracle 11.2 as oracle user. The installer may complain that you are missing some required packages. This is because it does not detect updated packages that you will have installed above. You can safely click Ignore All if this happens 
    cd database
./runInstaller
  17. Create the bb9 database by running dbca command as oracle user and then choosing appropriate (default?) options and db name = bb9 
    dbca
  18. Login as root
  19. Create /etc/init.d/dbora 
    #!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
export ORACLE_BASE=/home/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_HOME_LISTNER=$ORACLE_HOME
export ORACLE_OWNR=oracle
export ORACLE_OWNER=oracle
export ORACLE_SID=bb9
export ORACLE_UNQNAME=bb9
export ORACLE_HOSTNAME=localhost.localdomain
export PATH=$PATH:$ORACLE_HOME/bin
if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
then
    echo "Oracle startup: cannot start"
    exit 1
fi
case "$1" in
    start)
        # Oracle listener and instance startup
        echo -n "Starting Oracle: "
        su $ORACLE_OWNR -c "$ORACLE_HOME/bin/emctl start dbconsole"
        su $ORACLE_OWNR -c "$ORACLE_HOME/bin/lsnrctl start"
        su $ORACLE_OWNR -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"
        touch /var/lock/subsys/dbora
        echo "OK"
        ;;
    stop)
        # Oracle listener and instance shutdown
        echo -n "Shutdown Oracle: "
        su $ORACLE_OWNR -c "$ORACLE_HOME/bin/lsnrctl stop"
        su $ORACLE_OWNR -c "$ORACLE_HOME/bin/dbshut $ORACLE_HOME"
        su $ORACLE_OWNR -c "$ORACLE_HOME/bin/emctl stop dbconsole"
        rm -f /var/lock/subsys/dbora
        echo "OK"
        ;;
    reload|restart)
        $0 stop
        $0 start
        ;;
    *)
        echo "Usage: `basename $0` start|stop|restart|reload"
        exit 1
esac
exit 0
  20. Make dbora executable 
    chmod +x /etc/init.d/dbora
  21. Add dbora to startup and shutdown procedure 
    chkconfig --add dbora
  22. vi /etc/oratab. If you have followed the step above /re creating the database you may not need to add this line 
    bb9:/home/oracle/app/oracle/product/11.2.0/db_1:Y
  23. Manually configure bb9 SID listener for Oracle and restart listener services 
    vi /home/oracle/app/oracle/product/11.2.0/db_1/network/admin/listener.ora

    # listener.ora Network Configuration File: /home/oracle/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/oracle/app/oracle
SID_LIST_LISTENER =
  (SID_LIST = 
    (SID_DESC =
      (ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/db_1)
      (SID_NAME = bb9)
    )
  )

    lsnrctl stop
lsnrctl start

    You should now be able to issue the lisnrctl status command to see that your bb9 listener is running. You may only have one listener for the SID listed and with a status of UNKNOWN. This is fine for now and should change one Blackboard is up and running

    lsnrctl status

  26. Run blackboard installer AS ROOT 
    java -jar bb-as-linux-9.1.82223.0.jar

    stop)
        $BLACKBOARD_DIR/tools/admin/ServiceController.sh services.stop

    restart)
        $BLACKBOARD_DIR/tools/admin/ServiceController.sh services.restart
        ;;
    *)
        echo "Usage:  {start|stop|status|restart}"
        exit 1
        ;;
esac
exit $?
  28. Make blackboard executable 
    chmod +x /etc/init.d/blackboard
  29. Add blackboard to startup and shutdown procedure 
    chkconfig \--add blackboard
  30. vi /etc/inittab 
    id:3:initdefault:
  31. reboot

    very nice job on this!

    a little feedback from what i've experienced when i ran through it.

    •    related to step #16 and the pre-req check (solution via: http://telinit0.blogspot.com/2010/11/rhel6-64-bit-and-oracle-11g-r2.html) 
       install then started but encountered another error during a pre-req
        check - there are "missing" packages:

        libaio-0.3.105
        compat-libstdc++-33-3.2.3
        libaio-devel-0.3.105
        libgcc-3.4.6
        libstdc++-3.4.6
        unixODBC-2.2.11
        unixODBC-devel-2.2.11
        pdksh-5.2.14


        these packages are old versions. RHEL6 ships with the following:

        libaio-0.3.107-10.el6.x86_64
        libaio-0.3.107-10.el6.i686
        libaio-devel-0.3.107-10.el6.x86_64
        libaio-devel-0.3.107-10.el6.i686
        compat-libstdc++-33-3.2.3-69.el6.x86_64
        compat-libstdc++-33-3.2.3-69.el6.i686
        libgcc-4.4.4-13.el6.x86_64
        libgcc-4.4.4-13.el6.i686
        unixODBC-2.2.14-11.el6.x86_64
        unixODBC-devel-2.2.14-11.el6.x86_64


        (these packages will be installed by the kickstart file above).

        pdksh is no longer part of rhel6. i did install the following:

        ksh-20100621-2.el6.x86_64
        mksh-39-4.el6.x86_64


        So i chose "Ignore All" and continued the installation. it finished with
        no additional complaints.
    • after creating /etc/init.d/dbora, make sure its executable (maybe: chmod 550 /etc/init.d/dbora)
      • then make sure it is up and running before moving forward
    • i think that there may be a step missing before #19, regarding running the "Database Configuration Assistant" (located: /home/oracle/app/oracle/product/11.2.0/db_1/bin/dbca)
    • in Step #23 it looks like the Blackboard install directory is '/opt', the installer defaulted me to '/usr/local'.  (i wonder if the default setting is at all related to the location of the JDK)

    Thanks Again, this was very helpful!
