How to install OTD version 11.1.1.9.0
-----------------------------------------------------

OTD INSTALLATION&CONFIGURATION ,version-- 11.1.1.9.0

Steps to follow:-
------------------
1)Download the file from OTN "ofm_otd_linux_11.1.1.9.0_64_disk1_1of1.zip"

2)Unzip  the file

3)You will be getting a directory called "Disk1"

4)Run the installer from /Disk1 directory screen shot attached below

4)You can change the  Oracle home location which you  preferred as  per the requirement setup

5) Once the above steps done, click next

6)Click  next and finish

7)OTD installation  end here.

Steps to create a Admin server
----------------------------------------
In command line interface

(I)CREATE ADMIN SERVER

<oraclehome>/bin/tadm configure-server --user=otd_admin --server-user=root  --instance-home=/home/remyar/otd_remya/

The default port number  for OTD is 8989, you can use any port which you preferred.

(2)START THE OTD

start the OTD via startserv in CLI

 >>/home/remyar/otd_remya/admin-server/bin/startserv

o/p as per below screen shots.

Access the  OTD console via  http:<hostname:8989>


To create a origin server pool,  adding instances... updating ...WIP




Oracle Traffic Director Optimizations

Enabling SDP use to the wls origin servers
You can also optimize the communication between the OTD nodes and WLS
managed servers in the Origin Server Pool. The optimization is to enable OTD to
communicate with the origin server pool managed servers using the SDP protocol.
By doing so, the communication channel between the OTD frontend and the WLS
application tier is optimized to the fullest extent to take advantage of the Exabus
performance capabilities. Configuration change is required on both the OTD and the
WLS ends.
OTD
1. Log in to the OTD administration console for your environment using the
browser.
2. Select Server Pools and then origin-server-pool-1 that you created.
3. Search for the Address Family and using the drop down list change it to inetsdp.

4.Click Save.
5. Select each of the origin servers in the origin-server-pool.
6. Change the port from 7101 to 7102
7. Click Save.
8. Deploy both these changes
