Change OHS Port On Linux to Work on 80

Operating system : Oracle Linux 6.4
Oracle WebTier OHS 11.1.1.7

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 :

http://:7777/console  

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

http:///console 

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
/u01/fmw/Oracle_WT1/ohs/bin 

[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*
 httpd.conf      

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

unpack.sh Error -name=Value

The pack command creates a template archive (.jar) file that contains a snapshot of either an entire domain or a subset of a domain. You can use a template that contains a subset of a domain to create a Managed Server domain directory hierarchy on a remote machine.

The unpack command Creates a full domain or a subset of a domain used for a Managed Server domain directory on a remote machine. You may use unpack only with a template compatible with your current installation. The template can be any of the following:

  •  A domain template provided by BEA and packaged with your current installation
  •  A domain template created using the Domain Template Builder or WLST Offline
  •  A domain template created using the pack command
  •  A Managed Server template created using the pack command. A Managed Server template, by default, contains only the files necessary for creating a Managed Server domain directory.
You Can Check Oracle Documentation here for more information about the above commands.
When Trying to use unpack command with the below command:

./unpack.sh -domain=/u01/app/oracle/domains/IDMDomains -template=/u01/shared/IDMdomains.jar

The below error appear :

ERROR !!! ./unpack.sh -name=Value Missing

The Solution is simple :

-template attribute should come first. 

./unpack.sh  -template=/u01/shared/IDMdomains.jar -domain=/u01/app/oracle/domains/IDMDomains
