Oracle 10g installation on Solaris

# Pre-installation task:

# First of all following users and groups should be created

1. Group dba, oper (optional), oinstall
2. user oracle having oinstall as primary group

use the following commands to create required groups and user (as root user)

groupadd oinstall

groupadd dba
groupadd oper
useradd -g oinstall -G dba[,oper] -d /export/home/oracle -s /usr/bin/bash -m oracle
passwd -r files oracle

# if user nobody exists then

useradd nobody

# Now create a project for oracle so that all resources can be alloacated to this project as root user

projadd oracle

# kernel parameters: oracle recommends the following kernel parameters to be set to recommended value
# the values can be set in /etc/system file in solaris as the following syntax
# set parameter-name=value
# editing system file is deprecated and solaris recommends using projmod command to do so

1. Parameter Replaced by Resource Control Recommended Value

noexec_user_stack NA 1
semsys:seminfo_semmni project.max-sem-ids 100
semsys:seminfo_semmns NA 1024
semsys:seminfo_semmsl project.max-sem-nsems 256
semsys:seminfo_semvmx NA 32767
shmsys:shminfo_shmmax project.max-shm-memory 4294967295
shmsys:shminfo_shmmin NA 1
shmsys:shminfo_shmmni project.max-shm-ids 100
shmsys:shminfo_shmseg NA 10

# you can view the current values of this parameters as follows

prctl -n project.max-shm-memory -i project oracle

# you can set the values permanently by the following command (as root)

projmod -sK “project.max-shm-memory=(privileged,2G,deny)” oracle

# Directories

# create ORACLE_BASE directory

mkdir -p /mount_point/app/oracle_sw_owner
chown -R oracle:oinstall /mount_point/app/oracle_sw_owner
chmod -R 775 /mount_point/app/oracle_sw_owner

# now export the base directory as environment variable which will let oracle installer to handle
# creation of oracle_home and oraInventory directory

export ORACLE_BASE=/mount_point/app/oracle_sw_owner

# Storage option :

# if you plan to use file system as database storage you have to do the following. It is good practice
# that the database storage be in separate file system (i.e. in separate partition)

mkdir /mount_point/oradata
chown oracle:oinstall /mount_point/oradata
chmod 775 /mount_point/oradata

# if you plan to use recovery then you have to create a flash_recovery area

mkdir /mount_point/flash_recovery_area
chown oracle:oinstall /mount_point/flash_recovery_area
chmod 775 /mount_point/flash_recovery_area

# If you plan to use Automatic Storage Management (ASM) as storage option then you have to create a disk group and
# instance. you have to do the following in case of creating a disk group consisting of only one solaris partition/slice.
# To do so, first check whether the partition is mounted or not by

df -k

# if the partition is mounted then unmount it and remove the entry corresponding to that partition from /etc/vfstab

# now you set the ownership and permission of the partiton to oracle as follows (replace c0d0s4 accordingly)

chown oracle:dba /dev/dsk/c0d0s4
chmod 660 /dev/dsk/c0d0s4

# Now you have to set some environment variables for user oracle. edit the file .profile in oracle’s home diectory
# invoke

vi ~/.profile

umask 022

# activate this changes without restarting or relogin by invoking

. ./.profile

# To verify that the environment has been set correctly, enter the following commands. the first
# command will output 0022 and second will show the list of env. variables.

env | more

# Now run the oracle universal installer invoking …


# Universal Installer choice

1. Installation Method – Basic – /path/to/orahome – DBA group oinstall should be selected.
2. Inventory Directory – /path/to/inventoryDir – gorup oinstall need to be selected
3. Product-specific – see if every check succeded
4. make note of URLs of various web-based tools

# Installing Automatic storage management (single partition as disk group)

1. run universal installer
2. select Advanced Installation
3. specify home directory
4. select Configure … ASM in configuration option screen
5. Provide Disk group name
6. Redundancy level-external
7. The partition u have prapared earlier will appear as the candidate disk. select it and press next

# In database creation screen make note of database SID.
# After installation is finished the installer provides three URL’s

http://urmachine:1158/em (which is oracle enterprise manager)
http://urmachine:5560/isqlplus (iSQL*Plus web interface)
http://urmachine:5560/isqlplus/dba (iSQL*Plus DBA web interface)

# use first link and create a user and using that username and password u can login to second url
# and invoke sql statements using the web interface.

# the third url is for those users with dba privileges. this URL requires server authentication.
# to use this URL u have to create in iSQL*Plus DBA realm in oracle http server and grant webDba
# role to that user. To do so follow the following steps.

cd /path/to/oracle/home/ (i.e. $ORACLE_BASE/oracle/product/10.2.0/db_1)
cp oc4j/j2ee/isqlplus/application-deployments/isqlplus/config/jazn-data.xml config/
cp oc4j/j2ee/isqlplus/application-deployments/isqlplus/config/jazn.xml config/
jdk/bin/java$ORACLE_HOME/oc4j/j2ee/home/config/ -jar \
$ORACLE_HOME/oc4j/j2ee/home/jazn.jar -user “iSQL*Plus DBA/admin” -password welcome -shell

# this will start the oracle server’s authorization provider’s (JAZN) shell


# at that shell invoke the following

jazn> adduser “iSQL*Plus DBA” username password
jazn> grantrole webDba “iSQL*Plus DBA” username

# check that that ur user is created

jazn> listusers “iSQL*Plus DBA”

# Now login with the username and password u’ve just created in the 3rd URL that oracle installer provided.
# u have to provide sysdba username and password again.

# We are almost done with oracle 10g basic installation in solaris. One problem I have encountered is that
# when I restarted my machine after installation I couldnot connect to database with the URLs. the following
# error show..

ORACLE not found. ORA-…. shared memory realm does not exist .Error 2. no such file or directory.

# this is because after reboot the database instance is not started. so to have all things starts up in system bootup
# provide a script as follows. before that you have to do something…

# open the file /var/opt/oracle/oratab in your favourite editor. at the end of this file all the databases are listed like this


# if you install 2 database then you’ll have 2 such lines in this file .if the lines contain N at the end this means
# this database won’t be started during system bootup. change it to Y as above to make the database instance to start
# at system bootup

vi /etc/init.d/dbora

if [ ! -f $ORA_HOME/bin/dbstart ]
echo “Oracle startup: cannot start”
case “$1″ in
’start’) # Start the Oracle databases and listeners
su – $ORA_OWNER -c “$ORA_HOME/bin/dbstart $ORA_HOME”
su – $ORA_OWNER -c “$ORA_HOME/bin/lsnrctl start LISTENER”
su – $ORA_OWNER -c “$ORA_HOME/bin/emctl start dbconsole”
su – $ORA_OWNER -c “$ORA_HOME/bin/isqlplusctl start”
’stop’) # Stop the Oracle databases and listeners
su – $ORA_OWNER -c “$ORA_HOME/bin/isqlplusctl stop”
su – $ORA_OWNER -c “$ORA_HOME/bin/emctl stop dbconsole”
su – $ORA_OWNER -c “$ORA_HOME/bin/lsnrctl stop”
su – $ORA_OWNER -c “$ORA_HOME/bin/dbshut $ORA_HOME”

# now change this ownership and permission as follows

chown root:sys /etc/init.d/dbora
chmod 744 /etc/init.d/dbora

# now do this so that this script is called everytime the system boots up or shuts down.

cp /etc/init.d/dbora /etc/rc0.d/K10dbora
chown root:sys /etc/rc0.d/K10dbora
chmod 744 /etc/rc0.d/K10dbora

cp /etc/init.d/dbora /etc/rc2.d/S99dbora
chown root:sys /etc/rc2.d/S99dbora
chmod 744 /etc/rc0.d/S99dbora

# one little thing just add the following things to ~/.profile of the user oracle

ORACLE_BASE=/path/to/oracle/base/u’ve/set/earlier; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/oracle/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=SID that you noted during installation; export ORACLE_SID
PATH=$PATH:/usr/local/bin:$ORACLE_HOME/bin; export PATH

# Now reboot your machine .. and you are done..
