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.

I checked the application installation log file(/apps/inst/apps/TEST_localhost/logs/05030038.log).the above error was there.. while again investing the log file, observed that
the autoconfig was failing. So checked the autoconfig logfile (/apps/inst/apps/TEST_localhost/admin/log/05030620/adconfig.log), The below error was found.

[CVM Error Report]
The following report lists errors encountered during CVM Phase

  /apps/apps/apps_st/appl/ad/12.0.0/bin/adgentns.pl  -1
No of scripts failed in CVM phase: 1
AutoConfig is exiting with status 1

I didn't find the exact hit on support.oracle.com , so plan to run the perl scripts manually which was failing..SO ran the perl scripts and it autoconfig got successful.and click the
retry button of R12 Installtion screen, it got successful.
