Oracle9iAS (9.0.3.0.0) Installation On RedHat Advanced Server 2.1

In this article I'll describe the installation of Oracle 9iAS, Oracle's J2EE Application Server, on RedHat Advanced Server 2.1. The article assumes you've performed the standard advanced server installation including the development tools.

Download Software

Download the following software.

Unpack Files

First unzip the files.

gunzip linux_ias_903_Disk1.cpio.gz

Next unpack the contents of the files.

cpio -idmv < linux_ias_903_Disk1.cpio

You should now have a directory (Disk1) containing installation files.

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

Set Kernel Parameters

The following table contains minimum kernel settings. If the current settings exceed these figures then do not alter them.

Parameter Minimum Setting
SEMMNI 100
SEMMNS 256
SEMOPM 100
SEMMSL 100
SHMMAX 2147483648
SHMMIN 1
SHMMNI 100
SHMSEG 4096
SHMVMX 32767

The current semaphore settings can be viewed using the following command.

cat /proc/sys/kernel/sem

250 32000 32 128

The values listed are for the SEMMSL, SEMMNS, SEMOPM, and SEMMNI parameters. The adjusted values can be set as follows.

# echo SEMMSL_value SEMMNS_value SEMOPM_value SEMMNI_value > /proc/sys/kernel/sem
echo 250 32000 100 128 > /proc/sys/kernel/sem

The shared memory settings can be viewed using the following command.

cat shared_memory_parameter

The values can be set as follows.

echo 2147483648 >  /proc/sys/kernel/shmmax

Set the File Handles, Sockets and Process limit.

echo 65536 > /proc/sys/fs/file-max
ulimit -n 65536
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_change
ulimit -u 16384

The necessary parameter changes can be combined in a script and run during system startup.

echo 250 32000 100 128 > /proc/sys/kernel/sem
echo 65536 > /proc/sys/fs/file-max
ulimit -n 65536
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_change
ulimit -u 16384

Alternatively the following lines can be added to the "/etc/sysctl.conf" file.

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

In addition the following lines can be added to the "/etc/security/limits.conf" file.

oracle soft nofile 65536
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384

Adding lines into these files requires a reboot before they take effect.

Setup

Install the binutils RPM.

rpm -Uvh --force binutils-2.11.90.0.8-13.i386.rpm

Install KSH support.

rpm -Uvh --force pdksh-5.2.14-13.i386.rpm

Create the following symbolic links.

ln -s /sbin/fuser /bin/fuser
ln -s /opt/IBMJava2-131 /usr/local/java
ln -s /usr/local/java/bin/java /usr/local/bin/java

Create the new groups and users.

groupadd oinstall
groupadd dba
groupadd oper

useradd -g oinstall -G dba -s /bin/ksh oracle
passwd oracle

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/903_j2ee
chown -R oracle.oinstall /u01

Login as root and issue the following command.

xhost +<machine-name>

Login as the oracle user and add the following lines at the end of the ".profile" file.

# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/903_j2ee; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:/opt/IBMJava2-131/bin:$PATH; export PATH
PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/dcm/bin:$ORACLE_HOME/opmn/bin; export PATH
PATH=$PATH:$ORACLE_HOME/Apache/Apache/bin; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

PS1="`hostname`> "
set -o emacs
set filec

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

DISPLAY=<machine-name>:0.0; export DISPLAY

Start the Oracle Universal Installer (OUI) by issuing the following command in the Disk1 directory.

./runInstaller

During the installation enter the appropriate ORACLE_HOME and name then continue with the installation.

Post Installation

Once the installation is complete you should revert to the original version of binutils on the RedHat Advanced Server 2.1 CD2.

rpm -Uvh --force binutils-2.11.90.0.8-12.i386.rpm

Any subsequent relinks will generate errors. To prevent this remove the "-z defs" option from any makefiles which use it.

With the installation complete you can perform any administration tasks using Enterprise Manager:

It should be noted that the Enterprise Manager Website does not function properly unless the X Session that started it is still present. This means every time you need to use the EM website you must start an X Session, export the DISPLAY variable correctly and restart EM.

Hope this helps. Regards Tim...
