if you want to configure OHS ( WT ) to work on port 80 ( http ) avoiding insert Port.

For Example :

OHS default Port is 7777, if you want to leave it like this any call for the server should be like this :

But if you are using port 80 you have to do the below :

But on Linux if you need to use port 80 you have to be root, to do this follow the below step :

As root user :
[root@TST-WT1 bin]# pwd
[root@TST-WT1 bin]# chown root .apachectl
[root@TST-WT1 bin]# chmod 6750 .apachectl
As Oracle User
[oracle@TST-WT1 ~]$ cd /u01/fmw/admin/config/OHS/ohs1/ 

[oracle@SCADNP-WT1 ohs1]$ ls http*

Edit the file using any Editor and modify Listen from 7777 to 80Restart OHS using opmnctl command.
