4.12. About Global Oracle VDI Centers

4.12.1. Oracle VDI Center - Home and Foreign
4.12.2. Guest Pools
4.12.3. Oracle VDI Login and Desktop Selector Dialog

Global Oracle VDI Center is a useful feature for companies with multiple geographically separated sites. In such an environment, it is likely that users travel from one site to another site and need access to their desktops in their home Oracle VDI Center. Global Oracle VDI Centers extend the basic "hotdesking" experience known from a single Oracle VDI environment to encompass multiple Oracle VDI environments.

Global Oracle VDI Centers assume the existence of a global user directory infrastructure. Global Oracle VDI Centers are always enabled but unless you have prepared your user directory, you cannot take advantage of this feature. For more information about how to prepare the user directory, refer to section Section 4.13, “How to Prepare a User Directory for Global Oracle VDI Centers”.

4.12.1. Oracle VDI Center - Home and Foreign

An Oracle VDI Center is an individual Oracle VDI environment consisting of one or more Oracle VDI hosts. Users belong to one Oracle VDI Center at the geographical location they are normally working at, which is called their home Oracle VDI Center. When users are directly working on their home Oracle VDI Center, they will not notice any difference to a standalone Oracle VDI Center environment. If the user directory has been prepared accordingly and users are working from a foreign Oracle VDI Center, they have the possibility to switch to their home Oracle VDI Center or to get a desktop from one of the available Guest pools.

4.12.2. Guest Pools

A Guest pool is a pool with the "Guest" flag turned on and it provides desktops for users who have no assignments to desktops or other non-Guest pools on the Oracle VDI Center they are currently connecting to. A Guest pool is displayed in the desktop selector dialog only when a user meets this condition.

A pool can be set as a Guest pool using the Oracle VDI Manager or the CLI. Though they are not mandatory, the following are recommended settings for Guest pools:

  • Flexible desktop assignment

  • Small "Preferred Size" in order to not unnecessarily waste resources

  • Small number of "Free Desktops" in order to not unnecessarily waste resources

  • Large "Maximum Size" depending on how many guest users in the worst case are expected to work at the same time.

4.12.3. Oracle VDI Login and Desktop Selector Dialog

Initially after launching, the Oracle VDI Login Dialog looks the same as previous releases without Global Oracle VDI Centers. Once users provide a user name and password, the system determines whether they are connecting to their current home or to a foreign Oracle VDI Center based on the Global Oracle VDI Center related data in the user directory. If no such data can be found for the current user, the current Oracle VDI Center is considered to be the user's home Oracle VDI Center.

If users connect to their home Oracle VDI Center, nothing changes from the user experience perspective compared to previous releases of Oracle VDI. However, if users connect to a foreign Oracle VDI Center, the desktop selector dialog will contain several entries, for example:

  1. One or multiple Guest pool entries, if such pools have been configured correctly by the administrator. The user can get a local desktop on the foreign Oracle VDI Center from these Guest pools. If the user has previously acquired a desktop from one of the configured Guest pools, the user will see this desktop in the desktop selector dialog instead of the Guest pools, because Guest pools are only visible in the desktop selector if a user has had no previous assignments to desktops or other non-Guest pools.

  2. An entry enabling the user to switch to the user's home Oracle VDI Center.

If the user chooses to switch to the user's home Oracle VDI Center, the current session will be redirected to the user's home Oracle VDI Center. Once there, the user will see the Oracle Login dialog again with the user name prepopulated, but the user has to provide a password again.

After successful authentication, the desktop selector dialog will be display showing the assigned desktops and pools of the user.
