What is Oracle Coherence

If someone is new to this Oracle Coherence term, than following things one might ask;
1) What it is?
2) Why to use it?
3) Where does it comes into picture?

It is answered very well in the below post;
http://www.mythics.com/about/blog/the-features-and-benefits-of-oracle-coherence

But yes one will see this Oracle Coherence mostly when you are installing weblogic server say 10.3.6
At that time you have the option to either use the typical installation mode or go for the custom mode.

If you select custom mode, than there you will see that Oracle Weblogic Server & Oracle Coherence are the 2 products that will get installed.
One can untick the Oracle Coherence if not required, else it will by default gets installed with the weblogic server.

[OAM]: Start OAM Admin/Managed Server without getting prompt for username & password

The answer to this is boot.properties file, using this we can make the OAM Admin/Managed Server to start without getting prompt for the username & password.

Where to find this file & what does it contains?

When we install OAM in development mode, this file is created for AdminServer & placed under the <Domain_Home>/servers/AdminServer/security/ directory path.

Note: Domain Home in above directory is the place where you have created the user projects in the middleware home.

Under the above mentioned directory the boot.properties file is created & it contains the credentials details i.e.:
username=<encrypted text>
password=<encrypted text>

That's why in development mode you are not prompted for username & password when you start the Admin Server.

How to use this for Managed Server?

One can simply use the boot.properties file present in the AdminServer security directory & copy it to the oam_server security directory.

Note: This is true in case both the servers are in the same domain.

Like - in my case i have oam_server1 entry in
<domain_home>/servers/oam_server1

Inside this directory i couldn't locate the security folder, so i created a folder with the name 'security' & copies the 'boot.properties' file in it.

Now when i started my oam server it didn't asked me for the credentials.

What if i create my own boot.properties file?

One can create a new boot.properties files, that means it will contain plain text username & passowrd not the encrypted one.
When someone starts the oam server, it reads the credentials but it than encrypts the file. Thus the file contents are changed that means no more plain text is their.

I don't see a security folder in my server directory?

So create one a folder with name 'security' & create a file with name 'boot.properties. User credentials need to be entered in the properties file.

Creating User in Oracle Internet Directory(OID)

Follow below steps to create a new user in OID:

1) Log in to weblogic console & check whether ODSM (Oracle Directory Server Management) console is up & running:

    http://<host:port>/console

    Note: The console for ODSM is 'wls_ods1' in my setup & running on port 7005.

2) Now log in to the ODSM Console - http://<host:7005>/ODSM

     Note: This setup is a freshly created, so we need to create a connection first.


3) Create a User Connection:

4) New connection is created:

5) Choose Data Browser Option:

•  Expand the tree dc=com

•  Double Click the user cn=orcladmin

6) Now we need to create a user: Here i have selected the option 'Create a new entry like this one'

7) Complete the process for new user creation:

• Choose 'Next' on first page:

•  Provide 'cn' entry name & choose the relative distinguished name as 'cn'

•  On Optional Properties page, i have provided the new user password. Although this is a non-mandatory field.

•  Choose 'Finish' to complete the process.
