This document describes the process of installing Oracle® 8.0.5 and Oracle® 8.0.5.1 Enterprise Edition for Linux® onto a FreeBSD machine.

11.6.1. Installing the Linux® Environment

Make sure emulators/linux_base has been installed from the Ports Collection.

To run the intelligent agent, install the Red Hat Tcl package: tcl-8.0.3-20.i386.rpm. The general command for installing RPMs with the archivers/rpm port is:

# rpm -i --ignoreos --root /compat/linux --dbpath /var/lib/rpm package

This command should not generate any errors.

11.6.2. Creating the Oracle® Environment

Before installing Oracle®, set up a proper environment. This section only describes how to install Oracle® for Linux® on FreeBSD, not what has been described in the Oracle® installation guide.

11.6.2.1. Kernel Tuning

As described in the Oracle® installation guide, the maximum size of shared memory needs to be set. Do not use SHMMAX under FreeBSD as it is calculated from SHMMAXPGS and PGSIZE. Therefore, define SHMMAXPGS. All other options can be used as described in the guide. For example:

options SHMMAXPGS=10000 options SHMMNI=100 options SHMSEG=10 options SEMMNS=200 options SEMMNI=70 options SEMMSL=61

Set these options to suit the intended use of Oracle®.

Also, make sure the following options are in the kernel configuration file:

options SYSVSHM #SysV shared memory options SYSVSEM #SysV semaphores options SYSVMSG #SysV interprocess communication

11.6.2.2. Oracle® Account

Create a user account to be used as the oracle account. Add /compat/linux/bin/bash to /etc/shells and set the shell for the oracle account to /compat/linux/bin/bash.

11.6.2.3. Environment

Besides the normal Oracle® variables, such as ORACLE_HOME and ORACLE_SID set the following environment variables:

Variable	Value
`LD_LIBRARY_PATH`	`$ORACLE_HOME/lib`
`CLASSPATH`	`$ORACLE_HOME/jdbc/lib/classes111.zip`
`PATH`	`/compat/linux/bin /compat/linux/sbin /compat/linux/usr/bin /compat/linux/usr/sbin /bin /sbin /usr/bin /usr/sbin /usr/local/bin $ORACLE_HOME/bin`

It is advised to set all the environment variables in ~/.profile as follows:

ORACLE_BASE=/oracle; export ORACLE_BASE ORACLE_HOME=/oracle; export ORACLE_HOME LD_LIBRARY_PATH=$ORACLE_HOME/lib export LD_LIBRARY_PATH ORACLE_SID=ORCL; export ORACLE_SID ORACLE_TERM=386x; export ORACLE_TERM CLASSPATH=$ORACLE_HOME/jdbc/lib/classes111.zip export CLASSPATH PATH=/compat/linux/bin:/compat/linux/sbin:/compat/linux/usr/bin PATH=$PATH:/compat/linux/usr/sbin:/bin:/sbin:/usr/bin:/usr/sbin PATH=$PATH:/usr/local/bin:$ORACLE_HOME/bin export PATH

11.6.3. Installing Oracle®

Before starting the installer, create a directory named /var/tmp/.oracle which is owned by the oracle user. The installation of Oracle® should work without any problems. If errors are encountered, check the Oracle® distribution and configuration. Once Oracle® is installed, apply the patches described in the next two subsections.

A frequent error is that the TCP protocol adapter is not installed correctly. As a consequence, no TCP listeners can be started. The following actions help to solve this problem:

# cd $ORACLE_HOME/network/lib # make -f ins_network.mk ntcontab.o # cd $ORACLE_HOME/lib # ar r libnetwork.a ntcontab.o # cd $ORACLE_HOME/network/lib # make -f ins_network.mk install

Do not forget to run root.sh again.

11.6.3.1. Patching `root.sh`

When installing Oracle®, some actions, which need to be performed as root, are recorded in a shell script called root.sh. This script is found in orainst. Apply the following patch to root.sh so that it can find the FreeBSD location of chown. Alternatively, run the script under a Linux® native shell.

*** orainst/root.sh.orig Tue Oct 6 21:57:33 1998 --- orainst/root.sh Mon Dec 28 15:58:53 1998 *************** *** 31,37 **** # This is the default value for CHOWN # It will redefined later in this script for those ports # which have it conditionally defined in ss_install.h ! CHOWN=/bin/chown # # Define variables to be used in this script --- 31,37 ---- # This is the default value for CHOWN # It will redefined later in this script for those ports # which have it conditionally defined in ss_install.h ! CHOWN=/usr/sbin/chown # # Define variables to be used in this script

If Oracle® is not installed from CD, patch the source for root.sh. It is called rthd.sh and is located in orainst in the source tree.

11.6.3.2. Patching `genclntsh`

The script genclntsh is used to create a single shared client library when building the demos. Apply the following patch to comment out the definition of PATH:

*** bin/genclntsh.orig Wed Sep 30 07:37:19 1998 --- bin/genclntsh Tue Dec 22 15:36:49 1998 *************** *** 32,38 **** # # Explicit path to ensure that we're using the correct commands #PATH=/usr/bin:/usr/ccs/bin export PATH ! PATH=/usr/local/bin:/bin:/usr/bin export PATH # # each product MUST provide a $PRODUCT/admin/shrept.lst --- 32,38 ---- # # Explicit path to ensure that we're using the correct commands #PATH=/usr/bin:/usr/ccs/bin export PATH ! #PATH=/usr/local/bin:/bin:/usr/bin: export PATH # # each product MUST provide a $PRODUCT/admin/shrept.lst

11.6.4. Running Oracle®

After following these instructions, Oracle® should run as if it was running on Linux®.
