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.

Solution:

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.
2. Bounce the services.(both Apps+DB)
3. now able to launch the forms.
