This function is only available to administrators, so use this role prudently. During the installation of the Oracle VM Manager, a default admin account is created. And with this admin's account we can go about managing the users and groups.
Here it is possible to create new users, delete older or unwanted ones, assign different roles to those users, reset user password, and so on. Let's break it up into a few topics and have a look at it.
- Creating a User
- Viewing or editing details
- Changing a role
- Deleting a User
Creating a User
To create a User, perform the following:
- On the Administrator's page click User tab and then click on the Create button:
- Enter the necessary information such as:
- Username (avoid using user, manager, and administrator as username)
- Retype Password
- First Name
- Last Name
- Valid Email address
- We can select the account status, it could either be locked or unlocked and is only accessible when it's unlocked. We can lock an account for security reasons by using the status Locked. We can grant the following roles to this newly created user—User, Manager, or Administrator.
- Then select the Server Pools for this user and also select the group to which this user should belong to.
- Click on the Confirm button to confirm the information and we will get this information:
As we can see in the preceding screenshot this is a plain user and has no groups or servers assigned to it. However this was unlocked and was granted a User role.
Viewing or editing a User
Now let's view the User we just created.
- Click on the User tab on the Administrator page:
- Click on the Show link to view the Server Pools that the user is allowed to use:
We can now edit account details such as change email address, change account status, and so on.
- Let's change the User's email address:
- Modifying the account status to either locked or unlocked:
- Changing the role:
- Next, add the User to the Server Pool:
- Removing a User from groups or Server Pools:
Changing a User's role
Lets change regular Users' role to Administrator:
- On the Administrator's page, select the newly created User and click on the Edit button.
- Select the role and click Apply to effectively assign the role to the User:
- Once applied, we will be presented with the following screen:
To delete a User, we need to do the following on the Administrator's page. We can carry out a search and then select the User that we want to delete.
Click on the Delete button and confirm the User you want to delete:
Creating Groups in Oracle VM Manager is a convenient way to manage the endless number of users. It can be a very exhaustive task to assign privileges to the users and thus it is better to create groups for specific functions. That way we can copy users to those groups implying that all of the users can have the specific group functions that are designed for them.
Now let's go ahead with some Group Management tasks. By default, during installation, two groups are created namely, the "Public Group" and "My Workplace". The Public Group has all public virtual machines available to it and generally all users can deploy and view the VMs in this group. The My Workplace group contains private VMs and only the owners of the VMs can view VMs in this group.
Let's quickly check out some of the tasks within Group Management:
Creating a Group
Perform the following steps to create a Group:
- On the Administration page, click on the Group tab.
- Click on the Create button and enter the group name and description:
- Select users for this group and click the user name in the Available Users to add them to the Selected Users:
- Click Confirm to see the creation of the groups filled with desired users.
- And Voila! Our Group has been created.
Adding Users to a Group
Perform the following steps to add users to the group:
- On the Administration page, click on the User tab.
- Select/search users that you want to add to this group and click Edit.
- In the Group's section click the group under Available Groups column and move it to the Selected Groups column.
- Click on the Apply button to see the changes.
Editing a Group
Carry out the following steps to edit a group:
- Click on the group that you wish to modify or you can also search for it:
- Next, click on the Edit button to update the information.
Deleting a Group
To delete a group, we need to do the following:
- On the Administration page, select the group that you want to delete and click on the Delete button:
- Confirm the group that you want to delete and the group will be deleted.
In this article, we have learnt how to manage users and groups in Oracle VM Manager 2.1.2. We started off by dividing the section into two parts namely, managing users and managing groups. In user management, we learnt how to create a user, view or edit a user, change a user's role and delete a user. In group management, we learnt how to create a group, add users to a group, edit a group and finally delete a group.
