Oracle 10g EE Installation On Ubuntu 10

This is all 32 bit, no 64 bit software will be covered here.

To get Oracle 10g in 2013 requires a support account of course. Only 11g is available now. Basically I needed Oracle 10 because its still quite heavily used in global business circles. My security testing software may run into Oracle 10 (in fact, already has several times).

After some considerable problems with library linking related failures with Oracle 10g and Ubuntu 12 (12.04.2), I decided to just save time by backdating and using more compatible libraries. The install with Ubuntu 10.04.4 Lucid Lynx. The install with this older version (this is only for dev work, trust me i wouldn’t dream of using this in production) went like a dream.

Java

Note that many install guides insist on installing Oracle’s Java or some other JVM. I found that this was not necessary.

Other Libraries

and then libstdc++5 will be required. I found it here eventually…

http://old-releases.ubuntu.com/ubuntu/pool/universe/g/gcc-3.3/libstdc++5_3.3.6-17ubuntu1_i386.deb

and then …

dpkg -i libstdc++5_3.3.6-17ubuntu1_i386.deb

This process installs the library in the right place (at least where the installer for Oracle looks).

Users and Groups

sudo group add oinstall
sudo group add dba
sudo group add nobody
sudo user add -m oracle -g oinstall -G dba
sudo passwd oracle

Kernel Parameters

In /etc/sysctl.conf …

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

Reload to take effect…

root@vm-ubuntu-11:~# /sbin/sysctl -p

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

Change Limits

vi /etc/security/limits.conf

Add the following …

* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536

Change The System In A Suse Kinda Way

(Ubuntu isn’t a supported distro for Oracle DB and some subtle changes are needed)

sudo ln -s /usr/bin/awk /bin/awk
sudo ln -s /usr/bin/rpm /bin/rpm
sudoln -s /lib/libgcc_s.so.1 /lib/libgcc_s.so
sudo ln -s /usr/bin/basename /bin/basename

Oracle Base Directory

I went with more typical Oracle style directories here for some reason, but you can choose what’s best for you, as long as the ownership is set correctly (watch this space)…

sudo mkdir -p /u01/oracle
sudo chown -R oracle:oinstall /u01
sudo chmod -R 770 /u01

Update default profile

vi /etc/profile

Add the following …

export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=/u01/oracle/product/10.2.0/db_1
export ORACLE_SID=orcl10
export PATH=$PATH:$ORACLE_HOME/bin

Convince Oracle that Ubuntu is Redhat

sudo vi /etc/redhat-release

Add this …
“Red Hat Enterprise Linux AS release 3 (Taroon)”

Run The Installer

The zip file from Oracle – you will have unzipped it, it can be anywhere on the system, lets say /opt.
So after unzipping you will see a /opt/database directory.

chown -R oracle:install /opt/database

Then what’s needed? Start up an X environment (su to Oracle and startx), open a Terminal and…

/opt/database/runInstaller

Installer Options

Do not select the “create starter database” here and selection of Enterprise Edition worked for me, with the Installation Type option.

The installer will ask you run 2 scripts as root. Its is wise to follow this advisory.

The install proceeded fast. I only had one error related to the RDBMS compliation (“Error in invoking target ‘all_no_orcl ihsodbc’ of makefile ‘/u01/oracle/product/10.2.0/db_1/rdbms/lib/ins_rdbms.mk'”), but this was because I had not installed the libstdc++5

Create a Listener

So what you have now is a database engine but with no database to serve, and no Listener to process client connections to said database.

Again. within the Oracle owned X environment…

netca

and default options will work here, just to get a database working. netca is in $ORACLE_HOME/bin and therefore in the shell $PATH. Easy.

Create A Database

First up you need to find the GID for the oinstall group you created earlier…

cat /etc/group | grep oinstall

In my case it was 1001.

As root (UID=0) hose this into the /proc hugetlb_shm_group thus…

echo "" > /proc/sys/vm/hugetlb_shm_group

Again, as oracle user, do this…

dbca

…and again, default options will work in most cases here.

The database name should match the ORACLE_SID environment variable you specified earlier.

Database Service Control

The install script created a oratab file under /etc.
It may look something similar to…

root@ubuntu:~# cat /etc/oratab
....[comments]
orcl10:/u01/oracle/product/10.2.0/db_1:Y

The last part of the stanza (the “Y”) implies “yes” please start this SID on system start. This is your choice of course.

dbstart is a shell script under $ORACLE_HOME/bin. One line needs to be changed here in most cases…this is a basic substitution of your $ORACLE_HOME in place of the “/ade/vikrkuma_new/oracle” in the line after the comment “Set this to bring up Oracle Net Listener”: “ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle”

# Set this to bring up Oracle Net Listener

ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle

if [ ! $ORACLE_HOME_LISTNER ] ; then
echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
else
LOG=$ORACLE_HOME_LISTNER/listener.log

And that should be sufficient to just get a database up and running.

To shutdown the database, Oracle provides $ORACLE_HOME/bin/dbshut and this won’t require any editing.

“service” Control Under Linux

Personally I like to be able to control the Oracle database service with service binary as in:
service oracle start
and
service oracle stop

The script here to go under /etc/init.d was the same as my script for Oracle Database 11g…

root@ubuntu:~# cat /etc/init.d/oracle
#!/bin/bash
#
# Run-level Startup script for the Oracle Instance and Listener
#
### BEGIN INIT INFO
# Provides: Oracle
# Required-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Startup/Shutdown Oracle listener and instance
### END INIT INFO

ORA_HOME="/u01/oracle/product/10.2.0/db_1"

ORA_OWNR="oracle"

# if the executables do not exist -- display error

if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup: cannot start"
exit 1
fi

# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display

case "$1" in
start)
# Oracle listener and instance startup
echo -n "Starting Oracle: "
su - $ORA_OWNR -c "$ORA_HOME/bin/dbstart $ORA_HOME"
su - $ORA_OWNR -c "$ORA_HOME/bin/lsnrctl start"

#Optional : for Enterprise Manager software only
su - $ORA_OWNR -c "$ORA_HOME/bin/emctl start dbconsole"

touch /var/lock/oracle
echo "OK"
;;
stop)
# Oracle listener and instance shutdown
echo -n "Shutdown Oracle: "

#Optional : for Enterprise Manager software only
su - $ORA_OWNR -c "$ORA_HOME/bin/emctl stop dbconsole"

su - $ORA_OWNR -c "$ORA_HOME/bin/lsnrctl stop"
su - $ORA_OWNR -c "$ORA_HOME/bin/dbshut $ORA_HOME"
rm -f /var/lock/oracle
echo "OK"
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo "Usage: $0 start|stop|restart|reload"
exit 1
esac
exit 0

Most likely the only change required will be the ORA_HOME setting which obviously is your $ORACLE_HOME.

Quick Test

So after all this, how do we know our database is up and running?
Try a local test…as Oracle user…

sqlplus / as sysdba

This should drop you into the antiquated text based app and look something like…

oracle@ubuntu:~$ sqlplus / as sysdba
