Today’s presentation is based on a half-day training
session I led at LinuxWorld Expo in 1999. The material
has been condensed to fit a one hour timeslot and has
been thoroughly updated to cover Oracle 8i Release 2.
At http://www.dbspecialists.com/4dbas/present.html:
• 50 page workbook from LinuxWorld Expo

Oracle 8i on Linux: Differences
Oracle 8i on Linux is extremely similar to Oracle
8i on Solaris. A few areas of difference are:
• Operating system release and patch
requirements
• Method for setting kernel parameters
• Location of oratab file
Operating System Release and
Patch Requirements
Oracle 8i Release 2 is certified on
the following Linux distributions:
Red Hat 6.0
Red Hat 6.1
Red Hat 6.2
SuSE 6.3
SuSE 6.4
TurboLinux 6.0.2
Notes on Operating System
Requirements
• Some users have also found that Oracle 8i Release 2
works properly on Mandrake 7.1 (complete).
• You should be able to use the GNOME or KDE
window manager without problems.
I installed Oracle 8i Release 2 in a Red Hat 6.2
environment with GNOME. Out of the box, everything
ran smoothly. No operating system patches or additional
RPMs were necessary.
Setting Linux Kernel Parameters
Oracle 8i on Linux requires the same kernel parameter settings as
Oracle 8i on Solaris for SPARC. However, the default kernel
parameter settings and how you go about changing them are very,
very different.
• Default kernel settings on Red Hat 6.2 will work, but
SEMOPM should be increased to meet the documented
minimum requirement.
• Adjust kernel parameter settings by editing two files and
rebuilding the kernel:
• /usr/src/linux/include/asm/shmparam.h
• /usr/src/linux/include/linux/sem.h
Location of oratab file
/etc/oratab
instead of
/var/opt/oracle/oratab
Oracle 8i on Linux: Limitations
• The following features and options are not
available with the Linux release of Oracle 8i:
•
•
•
•
Oracle Parallel Server
Legato Storage Manager
Internet Directory Server
JDBC drivers for JDK 1.2
• In addition, the Oracle Data Migration Assistant
on Linux is not capable of upgrading an Oracle
8.0.5 database to Oracle 8i Release 2
Oracle 8i Information Specific to the
Linux Platform
• Documentation provided by Oracle Corporation
- Oracle 8i Release 2 for Linux Intel Installation
Guide
- Oracle 8i Release 2 for Linux Intel
Administrator's Reference
- Oracle 8i Release Notes for Linux Intel
• Text files in $ORACLE_HOME/relnotes
- Actually, these seem to be more specific to Solaris
than Linux!
