Oracle Apps R12.1 installation error-AC-00402: Unable to read driver file




While installing EBS R12.1 if we encounter below error:

Error:

 |          0% completed           AC-00402: Unable to read driver file: /u01/oracle/DEV121/db/tech_st/11.1.0/appsutil/template/addbtmpl.drv
RW-50010: Error: - script has returned an error:   1
RW-50004: Error code received when running external process.  Check log file for details.
Running Database Install Driver for DEV121 instance


Cause:

Seems the files which were downloaded were corrupted


Solution:

Check stage area according to MD5 Checksums for R12.1.1 Rapid Install Media [ID 802195.1]
Once all checks were passed re-try installation. In my case, I saw 2 warnings in the stage area which cause the issue. I downloaded files again and tried.

[root@ebs122 APPS12.1]# md5sum --check md5sum_Linux64.txt > r12_check_result.txt

md5sum: WARNING: 3 of 1887 computed checksums did NOT match
