How to create weblogic user

Dear DBA-mates, Hope you all are doing well!!!
How to create Weblogic user is a Weblogic administrative task. 

We are not sure if an Oracle Apps DBA also do it because we have never been done it as Oracle Apps DBA.

But it is important and easy task which we should know it. It may help in either in interview or work environment.

So, let’s start the steps for creating user in Weblogic:

1. Login to weblogic console url with Weblogic user and password.

2. Then click on "Security Realms" under Domain Structure, just below Services.

3. Then click on "myrealm".

4. After that click on "Users and Groups" tab (i.e 2nd tab). Then select "User" tab (just below 1st tab).

5. Then click on "New".

6. Then we will see "Create New user" form where you have to fill-up below details:

1. Name: Required Field
2. Description:
3. Provider:
4. Password: Required Field
5. Confirm Password: Required Field

Note: Name, password and Confirm password are Mandatory/Required fields which we need to provide value.

7. Now click on "Ok".

Please find the below path in shot-cut which may more helpful:

Home > Summary of Security Realms > myrealm > Users and Groups >New > Create New User

Also you can create here user, groups, members etc…

Note:

We have a complain about you guys that you people don’t answer the question’s here… hahahah, hmmm everyone wants ready meals: P
