installing oracle9i database on red hat linux 9
database version: oracle9i r2 (9.2.0.1.0)
1. creating users and groups:
-------------------------
become root and execute the following commands
$ su -
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -g dba oracle
# passwd oracle
2. creating directories.
--------------------------
we will install everything under /opt/ora9:
# mkdir -p /opt/ora9/product/9.2
# mkdir /var/opt/oracle
# chown oracle.dba /var/opt/oracle
# chown -r oracle.dba /opt/ora9
3. preinstallation (system configuration):
---------------------------
3.1 install these compatibility libraries:
compat-gcc-7.3-2.96.118.i386.rpm
compat-libgcj-7.3-2.96.118.i386.rpm
compat-libgcj-devel-7.3-2.96.118.i386.rpm
nss_db-compat-2.2-20.i386.rpm
you will find these packages on the installation cd s.
redhat rpms directory of cd1 first file
and rpms directory cd2 remaining 3 files
3.2 set kernel params to be correct at startup:
append these lines to /etc/sysctl.conf
you might want to change these values if you have more ram:
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
fs.file-max = 65536
.net.ipv4.ip_local_port_range = 1024 65000
append these lines into /etc/security/limits.conf
oracle soft nofile 65536
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
reboot the system so the kernel changes can take effect, or if rebooting is not an option, you can change the kernel params at runtime by issuing:
# echo 250 32000 100 128 > /proc/sys/kernel/sem
# echo 536870912 > /proc/sys/kernel/shmmax
# echo 4096 > /proc/sys/kernel/shmmni
# echo 2097152 > /proc/sys/kernel/shmall
# echo 65536 > /proc/sys/fs/file-max
# echo 1024 65000 > /proc/sys.net/ipv4/ip_local_port_range
4. preinstallation (oracle environment):
----------------------------
login as oracle user:
su - oracle
put the following lines in ~/.bashrc:
#oracle 9i
export oracle_base=/opt/ora9
export oracle_home=/opt/ora9/product/9.2
export path=$oracle_home/bin:$oracle_home/apache/apache/bin:$path
export oracle_owner=oracle
export oracle_sid=ora9i
export oracle_term=vt100
