Setting Up a Working Environment for

Oracle

This chapter covers the creation of user accounts, directories and Oracle environments for your Oracle

Database before you install.

32.1. Creating Oracle User Accounts

This section covers the command necessary to activate the required accounts to install an Oracle

Database.

Create the group of users to be granted with SYSDBA system privilege

su - root groupadd dba

Now create a group owner for Oracle files

groupadd oinstall

useradd -c "Oracle software owner" -g oinstall -G dba oracle

passwd oracle

For more information on the "oinstall" group account, see When to use OINSTALL

group during

install of oracle.

32.2. Creating Oracle Directories

Make sure that the Oracle file systems, in this example /u01, is large enough, see Section 30.5,

“Sizing Oracle Disk Space” for more information.

su - root

#mkdir -p /u01/app/oracle/product/9.2.0

#chown -R oracle.oinstall /u01

#mkdir /var/opt/oracle

#chown oracle.dba /var/opt/oracle

#chmod 755 /var/opt/oracle

32.3. Setting Oracle Environment Variables

Make sure to set the following Oracle environment variables before you execute runInstaller.

As the oracle user execute the following commands: # Make sure to set the LD_ASSUME_KERNEL

environment variable for Red Hat Enterprise Linux 3 and 4 !! # Use the "Linuxthreads with floating

stacks" implementation instead of NPTL:

export LD_ASSUME_KERNEL=2.4.1 # for Red Hat Enterprise Linux 3

export LD_ASSUME_KERNEL=2.4.19 # for Red Hat Enterprise Linux 4
