This chapter provides the answers to some frequently asked questions (FAQs) about Oracle Virtual Desktop Client for Android.
To view help on using Oracle Virtual Desktop Client, either tap one of the following buttons in the drop-down menu on the action bar, or the corresponding link on the connect screen:
Help. Displays this User Guide.
Gestures. Displays help on supported gestures.
If you use the Find Automatically option on the connect screen, you do not need to know the name of the server.
If you have connected previously to the server, the server name is shown in the servers list. You can select the required server from the servers list.
If you want to connect to a new server, you need to type the name of the server in the Server field. Depending on how your network is configured, you can use one or more of the following names:
The full name of the server on the network, also called the DNS name. For example,
vdi-1.example.com.The host name of the server. For example,
vdi-1.The IP address of the server. For example,
123.456.789.12.
Contact your administrator if you need to know the name of your Sun Ray Software or Oracle Virtual Desktop Infrastructure server.
You can use Oracle Virtual Desktop Client to connect to a server over a Virtual Private Network (VPN). A VPN is typically used to provide secure access to a company network to people from outside the network, such as employees working from home. See your administrator if you need help to configure your computer for connecting over a VPN.
When you are connected to a VPN, an icon is displayed in the Android status bar.
If you are experiencing problems when using a VPN, you might want to decrease the MTU setting to allow space for Internet Protocol Security (IPSec) headers. See Table 3.1, “Oracle Virtual Desktop Client Settings Screen”.
Contact your administrator for advice on the correct MTU setting for your network.
Sun Ray Software uses an on-screen display (OSD) to show the status of a connection. The OSD can be used to diagnose problems with a connection. For example, the following OSD icon indicates that the Sun Ray Software has not been enabled for access using Oracle Virtual Desktop Client.
If you are unable to connect to the Sun Ray server and this icon is displayed, contact your administrator.
Your firewall configuration might prevent you from connecting to the Sun Ray server. Check that the firewall settings on your network allow you to use Oracle Virtual Desktop Client to access the Internet.
If the connection to the Sun Ray server fails, Oracle Virtual Desktop Client displays a warning screen.
If your administrator has enabled audio for sessions, you can play and record audio on your Android tablet device. If you play a podcast, for example, the sound is output through the speaker on your tablet.
To record audio input from your Android tablet in a session, you can connect a microphone to the tablet, for example, and record the sound using software running on the server. Alternatively, you can use the built-in microphone on the Android tablet.
Yes. You can run other Android applications at the same time as you are using Oracle Virtual Desktop Client. This is called multi-tasking.
For example, when you tap the Home button to switch away from your session, the Oracle Virtual Desktop Client application is suspended. You can then run other applications on your Android tablet.
Provided that your server is not configured to close the connection after a period of inactivity, you can usually resume your session when you switch back to Oracle Virtual Desktop Client.
If the Android tablet is running low on memory, it may terminate the Oracle Virtual Desktop Client application to free up memory. You cannot then resume your session by switching back to Oracle Virtual Desktop Client. Instead, you must reconnect to your session.
If you are experiencing issues with low memory, close down unwanted applications before you start Oracle Virtual Desktop Client.
To scroll through a document or web page when you are working in a session, use the scroll gesture. The scroll gesture emulates the middle scroll wheel on a mouse.
To use the scroll gesture, drag upwards or downwards with two fingers.
An alternative way to scroll through a document or web page is to use the scroll bars on the application window.
See Section 2.3, “Using Gestures in a Session” for details of the supported gestures when you are working in a session.
You can use an external input device, such as a keyboard or mouse, with Oracle Virtual Desktop Client.
See your Android tablet documentation for more information about using an external keyboard or mouse. You may need to configure your Android tablet to use a Bluetooth wireless device.
The Sun Ray Windows connector (uttsc) is used to connect to a remote Windows desktop from within a Sun Ray Software session.
On a desktop computer, you display the toolbar for the Sun Ray Windows connector by moving the mouse to the top of the screen.
This feature can be reproduced on an Android tablet by dragging downwards with three fingers.
Table 4.1, “Gestures for Working in a Sun Ray Windows Connector Session” describes the gestures you can use with the Sun Ray Windows connector.
Table 4.1. Gestures for Working in a Sun Ray Windows Connector Session
Gesture | Description |
|---|---|
Drag downwards with three fingers | Display the Sun Ray Windows connector (uttsc) toolbar |
Drag upwards with three fingers | Display the on-screen keyboard |
You can copy and paste text between applications running on a virtual desktop and applications running on the Android tablet.
For example, you might be using a text editor application in a Sun Ray desktop session. You can copy text from this application and paste it into an application running on your Android tablet. Alternatively, you can copy text from an application running on your Android tablet and paste it into a text editor application running in your Sun Ray desktop session.
Oracle Virtual Desktop Client supports the copy and paste of Unicode characters.
To copy and paste, the clipboard service must be enabled on the server. This is done by enabling the Oracle Virtual Desktop Client Clipboard option in the Sun Ray Software Admin GUI, as described in the Sun Ray Software Administration Guide.
To use the clipboard service in a Sun Ray or Oracle Virtual Desktop Infrastructure session, the remote server must be running at least Sun Ray Software version 5.3. This version of Sun Ray Software is supplied with Oracle Virtual Desktop Infrastructure version 3.4.
Clipboard sharing is configured on the Android tablet by default. Note that clipboard sharing is not available if the clipboard service is not enabled on the server.
If you are displaying a remote session and you rotate your Android tablet between landscape and portrait display, the session is resized automatically.
This feature is called dynamic session resizing.
To configure dynamic session resizing, use the Dynamic Resize setting on the Oracle Virtual Desktop Client Settings screen. This setting is enabled by default. See Table 3.1, “Oracle Virtual Desktop Client Settings Screen”.
To use dynamic session resizing, the feature must be enabled on the server. See the Sun Ray Software Administration Guide for details.
Sometimes you may want to be able to use the full screen space of your Android tablet. For example, if you are displaying a desktop session this might give the best user experience.
The action bar is the menu bar across the top of the Android screen. To maximize screen space, you can hide the action bar as follows:
Tap the Hide icon in the action bar.
To redisplay the action bar, tap the Android Back button.
When you disable the Full Screen option on the Oracle Virtual Desktop Client Settings screen, the action bar screen area is not used. The session is displayed underneath the action bar and is not resized if you hide the action bar.
If you want to use the maximum available screen space, enable the Full Screen option and hide the action bar.
When you are displaying a large desktop session on your Android tablet, you may see one of the following issues:
The desktop session does not fit well on the tablet screen; or
Desktop icons, text, and menus are too small
For the best user experience when displaying a desktop session, you can configure Oracle Virtual Desktop Client to display the session in a resolution that works best on your tablet screen.
Use the Session Size setting on the Oracle Virtual Desktop Client Settings screen to select a session size. Typical landscape and portrait settings that should work well on an Android tablet are available. See Table 3.1, “Oracle Virtual Desktop Client Settings Screen”.
If you rotate the tablet screen, the pixel dimensions for the Session Size setting are swapped. For example, if you rotate a 1024 x 768 display, a resolution of 768 x 1024 is used.
