Solution:
1. Run WFLOAD with FORCE option as the applmgr user:
$FND_TOP/bin/WFLOAD apps/<apps pwd> 0 Y FORCE $IRC_TOP/patch/115/import/US/ircntf.wft
2. Use adctrl hidden option #8, to skip the failed job.

Reference:
IRCNTF.WFT Fails During R12.1.1 Upgrade (Doc ID 1329530.1).
Oracle Support advice is to skip this error and complete the upgrade. This error should not impact any iRecruitment functionality apart from Generic Notifications in iRecruitment which is introduced in 12.1. Furthermore they suggest to apply Patch 9371492: IRCNTF.WFT FAILS DURING R12.1.1 UPGRADE. This isn’t possible during deployment of patch 6678700, so I run WFLOAD with the FORCE optio

Solution :-
The sestatus command provides a configurable view into the status of SELinux.

You can use the command getenforce to see the current mode of SELinux. To disable SELinux temporarily you can use the command setenforce Permissive. In permissive mode the denials will still occur and will be logged but the operations will not be blocked. Permissive mode is the recommend mode by Oracle Support.

For permanent change

[root@otm ]# cd /etc
[root@otm ]# ls -alh grub.conf
lrwxrwxrwx 1 root root 22 Aug 25 16:25 grub.conf -> ../boot/grub/grub.conf
[root@otm etc]# cp grub.conf grub.conf_ORG
[root@otm etc]# ll grub*
lrwxrwxrwx 1 root root 22 Aug 25 16:25 grub.conf -> ../boot/grub/grub.conf
-rw------- 1 root root 865 Aug 25 17:04 grub.conf_ORG

vi grub.conf


To change from enforcing to permissive we will add enforcing=0 to end of the line beginning with kernel.
