The new IBM DB2 11.x collaboration features are provisioned by IBM’s cloud platform called Bluemix. IBM’s Bluemix provides several IaaS (Infrastructure as a Service) and PaaS (Platform as a Service) cloud services. IBM’s Bluemix offers a cloud service for DB2 11.x called DB2 on Cloud. In addition to the benefits inherent to a cloud platform, such as providing a scalable, reliable, fully managed service, Bluemix offers some collaboration features for team development. 

IBM’s DB2 on Cloud is a DB2 database on IBM’s SoftLayer cloud platform. Secure SSL connections, high availability, and support for all native DB2 drivers, SQL, JDBC, ODBC and .NET are some of its other features. DB2 on Cloud is SQL compatible with Oracle, which makes it easier to integrate with Oracle database based applications. DB2 on Cloud supports AWS S3 backups. The DB2 database version on DB2 on Cloud is 11.1 by default. This article has the following sections:

Overview of Bluemix Collaboration Features

Bluemix provides several collaboration features for an organization and its team members. First, to get familiar with the terminology used by Bluemix, we shall discuss some collaboration entities or terms. When a Bluemix account is created,an AccountOwner gets created, and an Organization gets registered with Bluemix.  When logging into a new Bluemix account, a dialog prompt “Create organization” to create an Organization is displayed, as shown in Figure 1. Select from the suggested Organization names or specify a different name and click on Create to create a top-level Organization associated with the Bluemix account owner. The Organization name must be unique in Bluemix (not just for a Bluemix account) and consist of at least a single character.

Figure 1. Create Organization

Next, a dialog prompt “Create space” to create a Space gets displayed, as shown in Figure 2. Select from one of the suggested Space names or specify a different name and click on Create.

Figure 2. Create space

An Organization and a Space get created and a Summary dialog prompt gets displayed, as shown in Figure 3.  Click on I’m Ready to start using Bluemix.

Figure 3. Summary – Organization and Space created

The Bluemix Dashboard gets displayed. Initially a Bluemix account does not include any apps. An “Organization” is the fundamental unit of collaboration and consists of team members, spaces, applications, services, domains, and routes as a single unit for management. Although to start with an Organization is associated with a single geographical region, an Organization may span multiple geographical regions. A domain is an Internet route allocated to an organization. By default, a domain is a system domain and custom domains may be added. An application created in an Organization is assigned a sub-domain. Each Organization has a Quota that represents the resource limits for the memory and number of services for the organization. A Quota is created when an Organization is created and may be modified as required as new services and applications are created. By default, a single Bluemix Account Owner is associated with a single Organization and the account owner may add multiple Organizations. To manage Organizations click on Manage Organizations from the account drop-down, as shown in Figure 4.

Figure 4. Account>Manage Organization

The Manage Organizations page in the Bluemix Dashboard gets displayed, as shown in Figure 5.

Figure 5. Manage Organizations

The Organization may be edited by selecting View Details and subsequently Edit Org, as shown in Figure 6.

Figure 6. View Details>Edit Org

While the top level collaboration or grouping unit is called an Organization, the next level below it is called a Space. When a new Bluemix account is created a new Organization and a Space called “dev” associated with it are also created. A Space consists of a set of applications, services, and team members. Team members exist in an Organization and in a Space. Team members in an Organization and a Space have user roles, with each user role being associated with a set of permissions. The user roles at the Organization level are Manager, Billing Manager, and Auditor; and the user roles at the Space level are Manager, Developer, and Auditor. The different roles are discussed in Table 1.

Table 1. Roles that may be assigned to a Team Member in an Organization and a Space

Role Description and Privileges
Organization Manager An Organization Manager is able to update the organization
Organization Billing Manager A read-only role; a Billing Manager is able to view billing related information
Organization Auditor A read-only role; an Organization Auditor is able to view the organization
Space Manager A Space manager is able to update the Space
Space Developer A Space Developer is able to manage applications and services in a Space
Space Auditor A read-only role; a Space Auditor is able to view a Space

The roles with write privileges are Organization Manager, Space Manager and Space Developer. An Organization Manager has the following permissions:

– Create, view, edit, or delete Spaces

– View the Organization’s resource usage and Quota

– Invite team members to the organization

– Manage who has access to the Organization and their roles

– Manage custom domains

A Space Manager has the following permissions:

– Add existing team members to a Space and manage their roles within a Space. A Space Manager cannot invite new team members.

– View the number of instances, service bindings, and resource usage for each application within a Space.

A Space Developer has the following permissions:

– Create, delete, and manage applications within a Space, including starting, stopping, and deploying apps.

– Create, delete, and manage services within a Space, including binding or unbinding a service to an application.

– View the number of instances, service bindings, and resource usage for each application.

– Associate an internal or external URL with an application.

All user role assignments are editable, except that the Account Owner must be assigned the Organization Manager role and that each Space must have at least one Space Manager. Each new team member could be assigned the Manager role in an Organization but does not have to be.  With multiple team members as Managers in an Organization, if removal of the Manager role is from the Account Owner is attempted, the message, “You cannot remove yourself as a manager of the <Organization name> Organization.” gets displayed; <Organization name> being that particular Organization name.  Each Space must have at least one team member assigned to manage the Space (Space Manager) but it does not have to be the Account Owner.  Any team member could be made a Manager for a Space. With multiple team members as Space Managers, if the Space Manager role is removed from the Account Owner, a confirmation prompt, “Are you sure you want to remove yourself as a manager of the Space?” is displayed; being that particular Space name. Organization and Space Auditor have read-only or view-only permissions in a Space, as mentioned before.

When a Bluemix account is created it is associated with a single Organization to start with, and the Account Owner may add other Organizations, which inherit the team members (also called users), domains, and Quota from the starter Organization. Once an Organization is created it cannot be deleted from the Dashboard. The Account Owner is also a team member but with a difference from other team members in that the Account Owner cannot be removed from the team.

While a new Organization inherits team members from the top level Organization the team members in each Organization may be edited independent of other Organizations. A Space may be edited or deleted. While an Organization name is unique across all Bluemix accounts, a Space name is unique only within an Organization.

Figure 42. User invited

The user invited must accept the invitation before being added to an Organization.

Adding an Organization

Only a Bluemix Account Owner or a team member with Manager user role permission in an Organization may add a new Organization and, once added, an Organization cannot be deleted. Select Manage Organizations to add a new Organization, as shown in Figure 43.

Figure 43. Manage Organizations

To add a new Organization click on Add new Org as shown in Figure 44.

Figure 44. Add a New Org

In the Add a New Org specify an Organization name and click on Add as shown in Figure 45.

Figure 45. Adding a new Organization

A new Organization gets added, as shown in the Confirmation message in Figure 46.

Figure 46. New Organization Added

The new Organization added gets listed in Manage Organizations, as shown in Figure 47.

Figure 47. Manage Organizations

Click on View Details to view the details of an Organization and click on Close Details to close, as shown in Figure 48. An Organization detail includes the Organization itself with a link (Edit Org) to edit the Organization; for instance, to add or remove users and add or remove domains. Spaces in each region associated with an Organization are also listed with the provision to edit a Space with the Edit Space link. New Spaces may be added with the Add Space link.

Figure 48. Organization Details

Adding Team Members

The Team Directory lists all the team members in a Bluemix account. The Account Owner is listed in the Team Directory as “Owner”, as shown in Figure 49.

Figure 49. Team Directory

To display the roles associated with a team member, click on View Roles. In our example, the team member is listed as the Account Owner with the Manager user role in the Organization, as shown in Figure 50. The Spaces and the user roles associated with the Spaces in an Organization may be displayed with the View Space link.

Figure 50. View Details

To invite team member/s click on Invite Team Members as shown in Figure 51.

Figure 51. Invite Team Members

Team members may also be invited from the Account drop down selection with Invite Team Members. In the Invite Team Members, page select an Organization for the new team member/s, as shown in Figure 52. Click on Next.

Figure 52. Inviting a New Team Member

Select one or more Spaces for the new team member/s, as shown in Figure 53.  Click on Next.

Figure 53. Inviting a New Team Member

As shown in Figure 54, a new team member has the Auditor role, which has read-only privileges, assigned in an Organization and this role is not modifiable to a different role when adding a new team member. Subsequent to adding a new team member, its role in an Organization may be modified by selecting Manage Organizations and Edit Org for the Organization. A new team member may be assigned only the Auditor role or the Developer role, which provides write access, in a Space when adding a new Space. Subsequently the team member roles in a Space may be modified as required. Select the checkbox, specify an email to send the new team member an invitation, and click on Send. The Organization Owner is already a team member by default and may be assigned the roles discussed earlier, the Manager role in the Organization being mandatory for an Owner. Because the Owner is associated with the mandatory Manager role, the individual designated as Owner may want to be added again as a new team member to function in another capacity, as a team member without the mandatory Manager role. As this fact implies, the Owner may be sent an invitation to be added as a new team member and, furthermore, the invitation may be sent to the same email address as was registered by Owner when creating the Bluemix account, as shown in Figure 54.

Figure 54. Sending Invitation to a New Team Member

An invitation gets sent, as shown in Figure 55.

Figure 55. Invitation Sent

Multiple team members may be invited with the “invite them all at once” link. Specify multiple email addresses separated by a “,” and click on Next as shown in Figure 56.

Click on Send to send invitations, as shown in Figure 57.

Figure 57. Sending Invitation to a New Team Member

The new team member gets listed in the Team Directory but the status is Pending, as shown in Figure 58, until the team member accepts the invitation.

Figure 58.  New Team Member with Pending Status

Other than re-adding the Owner as a team member to function in a limited capacity, other new team members cannot be added as new team members more than once because all team member roles are editable (add/remove) as required. A new team member who is not also the Owner is shown in Figure 59.

Figure 59. New Team Member with Pending Status

An invited team member has to click on the Join Org link in an email message sent to the team member to be added to the Organization. The Pending status gets removed when a new team member accepts an invitation to join, as shown in Figure 60.

Figure 60. Pending Status Removed

The team member’s user roles may be listed with View Roles, as shown in Figure 61.

Figure 61. User Roles

The Invite Team Members window lists the invitation status of team members in three categories: Pending, Accepted, and All. The Accepted view lists the team members who have accepted the invitation to join an organization, as shown in Figure 62. The All view lists all team members including pending and accepted.
