"cannot open shared object file" when installing Oracle Database 10g on Oracle Enterprise Linux 5.5

Problem:

When installing Oracle Database 10g (10.2.0) on Oracle Enterprise Linux 5.5 or Red Hat Enterprise Linux 5.5, you may receive the following error:

oracle@oradev:/u01/app/install_software/database> ./runInstaller
Starting Oracle Universal Installer...

The database install file used was 10201_database_linux32.zip.

Additional Notes:

Note that out-of-the-box, Oracle Database 10g does not recognize OEL 5.5 as a valid operating system. There are 3 different options to work around this:

1. Update the installation file database/install/oraparam.ini and replace all occurences of "redhat-3" to "redhat-5".

2. Update the /etc/redhat-release file to trick the installer.

3. Follow Metalink Note ID 564174.1.

Solution:

As for the error above, simply mount Disk 3 of the OEL 5.5 media, and apply the following RPM:

rpm -ivh libXp-1.0.0-8.1.el5.i386.rpm

Rerun the installer and you should be fine.

Applicable Versions:

• Oracle Enterprise Linux 5.5 32-bit
• Oracle Database 10g (10.2.0.1) 32-bit
