Step By Step Installation of Standalone RDBMS Software

Going forward with 11gR2 oracle recommending out of place upgrade so providing full installer for major upgrades (i.e. ,, instead of patchsets. Then we can apply bundle patch or custom patches based on our requirement.

For, software is available on MOS with patch number 10404530 and could be easily downloadable. This patch contains total 7 files but we need only & (2.32 GB) to install DB software. This patch is actually full release and could be used for upgrade as well as new installation.

Prerequisite RPMs

























Note: 64 bit installation also searches for i386 unixodbc rpms.

In order to check missing or old RPM use following commands:

rpm -qa | egrep -i ‘binutils|compat-libstdc|elfutils-libelf’ | sort -k1

rpm -qa | egrep -i ‘^gcc|^glibc|^kernel-headers|^ksh|^libaio|^libgcc|^libgomp’ | sort -k1

rpm -qa | egrep -i ‘^libstdc|^make|numactl|sysstat|unix’| sort -k1

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048586


Download the software and unzip it then go to software stage directory and start installer:


Uncheck “I wish to receive security updates via My Oracle Support” and click “Next”

Click “Yes”

Opt for “Skip software updates” and click “Next”

Opt for “Install database software only” and click “Next”

Opt for “Single instance database Installation” and click “Next”

Click “Next”

I have opted for “Enterprise Edition” , you could choose as per your requirement and click “Next”

Click “Next”

Provide Oracle Base & Software Location and click “Next”.

On my server this wasn’t first installation, so oracle inventory was already in place otherwise installer would have asked you to do so.

Choose appropriate groups for OSDBA & OSOPER and click “Next”

In case OUI detected any mismatch with pre-requisites then it will give you option to click on “fix and check” which will pop-up a window suggesting “/tmp/CVU_11.” script to run as root. It will fix the gaps for you. It’s one of the great feature in OUI which is removing complexity during installation.

Click “Install”

Wait and watch… it will take 5-10 minutes, based on your system to complete the installation.

Now open a new session as root and execute script.

[root@mask11g ~]# /u01/app/oracle/product/

Performing root user operation for Oracle 11g

The following environment variables are set as:


ORACLE_HOME= /u01/app/oracle/product/

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The contents of “dbhome” have not changed. No need to overwrite.

The contents of “oraenv” have not changed. No need to overwrite.

The contents of “coraenv” have not changed. No need to overwrite.

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Finished product-specific root actions.

Click “Close”.

RDBMS Installation is now done.
