Cause
The issue is caused by the openmotif21 package which is missing from the system.
For example, for Oracle Enterprise Linux 5 or Red Hat Enterprise Linux 5 the missing package is:
openmotif21-2.1.30-11.EL5.i386.rpm.
Please check Note 402310.1 Oracle Applications Installation and Upgrade Notes Release 12 (12.0.4) for Linux (32-bit) in order to identify the missing RPM.


Note: Be sure you have all rpms displayed in Note 402310.1 Oracle Applications Installation and Upgrade Notes Release 12 (12.0.4) for Linux (32-bit).


Solution
To implement the solution, please execute the following steps:
1. Install package openmotif rpm.
For example, for Oracle Enterprise Linux 5 or Red Hat Enterprise Linux 5 the missing package is:
openmotif21-2.1.30-11.EL5.i386.rpm.
