Simple note of a quick DB install for test purpose.

Steps to install the DB

Install dependencies for Oracle:

[root@lab-oem ~]# yum install gcc.x86_64 gcc-c++.x86_64 glibc-devel.x86_64 glibc-headers kernel-headers libstdc++-devel.x86_64 glibc-headers.x86_64 sysstat.x86_64 elfutils-libelf-devel.i386 libaio-devel.x86_64

Create the user oracle, the group dba and the /OEMDB:

[root@lab-oem database]# groupadd -g 200 dba
[root@lab-oem database]# useradd -g 200 -u 200 oracle
[root@lab-oem ~]# mkdir /OEMDB
[root@lab-oem ~]# chown oracle:dba /OEMDB

Change limitations for the dba group in '/etc/security/limits.conf':

@dba soft nproc 2047
@dba hard nproc 16384
@dba soft nofile 4096
@dba hard nofile 65536

Add the kernel parameters in '/etc/sysctl.conf' and reload with 'sysctl -p':

kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
net.ipv4.ip_local_port_range = 32768 61000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
fs.file-max = 6815744

Log as oracle, keep X11 wih 'xauth add' and start the 'Oracle Universal Installer':

[root@lab-oem ~]# xauth list
lab-oem/unix:10  MIT-MAGIC-COOKIE-1  7ff8859f65e1d01c7db147a61d07f0b3
[root@lab-oem ~]# su - oracle
[oracle@lab-oem ~]$ cd /mnt/appz/Oracle/RDBMS-
[oracle@lab-oem database]$ xauth add lab-oem/unix:10  MIT-MAGIC-COOKIE-1  7ff8859f65e1d01c7db147a61d07f0b3
[oracle@lab-oem database]$ ./runInstaller

Quick check the installed DB

Check these files:

cat /OEMDB/oracle/product/11.2.0/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /OEMDB/oracle/product/11.2.0/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

    (ADDRESS = (PROTOCOL = TCP)(HOST = lab-oem.novalan.priv)(PORT = 1521))
      (SERVICE_NAME = oemdb.novalan.priv)
cat /OEMDB/oracle/product/11.2.0/network/admin/listener.ora
# listener.ora Network Configuration File: /OEMDB/oracle/product/11.2.0/network/admin/listener.ora
# Generated by Oracle configuration tools.

      (ADDRESS = (PROTOCOL = TCP)(HOST = lab-oem.novalan.priv)(PORT = 1521))


Check connectivity:

[oracle@lab-oem database]$ . oraenv
ORACLE_SID = [oracle] ? oemdb
The Oracle base has been set to /OEMDB/oracle
[oracle@lab-oem database]$ env | grep ORA

sqlplus sys/Oracle123@oemdb as sysdba
