Array properties (array-wide)

Attributes on the Array Properties panel of Array Manager are general settings for the array. The attributes apply to all array members.

From the command line, use tarantella config to view and edit these settings.

Array Manager	Command line	Description
Port Numbers (unencrypted connections)	`--array-port-unencrypted tcp_port`	The TCP port number used for unencrypted connections between client devices and Secure Global Desktop servers. Open this port in your firewall to enable connections from users who have standard connections (connections not using SSL). You should restart every Secure Global Desktop server in the array for changes to this attribute to take effect.
Port Numbers (encrypted connections)	`--array-port-encrypted tcp_port`	The TCP port number used for encrypted connections between client devices and Secure Global Desktop servers. Open this port in your firewall to enable connections from users who have secure (SSL-based) connections to Secure Global Desktop. You should restart every Secure Global Desktop server in the array for changes to this attribute to take effect.
Port Numbers (connections between array members)	`--array-port-peer tcp_port`	The TCP port number used for connections between Secure Global Desktop array members. These connections are used to replicate information across the array. You should restart every Secure Global Desktop server in the array for changes to this attribute to take effect.
Log Filter	`--array-logfilter filter...`	Which diagnostic messages are logged, and where. This attribute contains multiple values, each of the form `component/subcomponent/severity:destination`. Use the wildcard `` to match multiple components, subcomponents and severities. On the command line, remember to quote any filters containing wildcards to stop your shell from expanding them. Valid destinations are a filename or the TFN name of a plug-in log handler. On the command line, separate each `filter` with a space. Remember to quote any filters that contain wildcards ``, to stop your shell from expanding them. File names may include the placeholder `%%PID%%`, which is substituted with a process ID. On the command line, separate each `filter` with a space. In Array Manager, separate each filter with a RETURN. For detailed information on setting log filters and viewing log output, see Using log filters to troubleshoot problems with the Secure Global Desktop server. Changes to this attribute take effect immediately.
Enable billing services	`--array-billingservices 1 \| 0`	Whether to enable billing services across the array. This may use significant additional disk space on array members. If enabled, you can use `tarantella query billing` to analyze the billing logs. Changes to this attribute take effect on an array member the next time the Secure Global Desktop server starts.
Enable resource synchronization	`--array-resourcesync 1 \| 0`	Whether to enable replication of resources across the array. If enabled, synchronization starts at a time determined in Tuning properties for each array member. Changes to this attribute take effect immediately.
Client Drive Mapping: Let users access client drives	`--array-cdm 1 \| 0`	Whether to enable client drive mapping (CDM) across the array, see configuring client drive mapping for details. If you enable drive mapping, CDM services only become available when you restart all Secure Global Desktop servers in the array. To manually start CDM services without restarting the array, run the `tarantella start cdm` command on all members of the array. If you disable drive mapping, the CDM processes only stop when you restart all Secure Global Desktop servers in the array. To manually stop CDM services without restarting the array, run the `tarantella stop cdm` command on all members of the array. Changes to this attribute only take effect for new webtop sessions.
Client Drive Mapping: Use WINS for better performance	`--array-cdm-wins 1 \| 0`	Whether to enable WINS to improve performance of client drive access. Without WINS, performance may be limited by known problems with Microsoft Windows networking. WINS services use port 137/udp on the Secure Global Desktop server. Only enable WINS if either of the following is true: Your Microsoft Windows application servers are on the same subnet as an array member. Your Microsoft Windows application servers list an array member as a WINS server. Changes to this attribute take effect on an array member the next time the Secure Global Desktop server starts.
Client Drive Mapping: Fallback Drive	`--array-cdm-fallbackdrive letter_direction`	For client drives that can't be mapped using the configured drive letter because that drive letter is already in use, which drive letter to start searching from and the direction to search. The first unused drive letter is used to map the client drive. Allowed values are of the form `[a-zA-Z][+-]`, for example `V-` to start at drive V and search alphabetically backwards, or `f+` to search forwards from drive F. Drive letters are case-insensitive. Changes to this attribute take effect for new webtop sessions.
Audio: Enable Windows audio service	`--array-audio 1 \| 0`	Whether to enable Windows audio services across the array. Audio is only available for applications running on a Microsoft Windows 2003 application server. Audio redirection must also be enabled on the server. Changes to this attribute only take effect for new webtop sessions.
Audio: Windows audio sound quality	`--array-audio-quality low \| medium \| high`	The sample rate of the audio data. Adjusting the audio quality increases or decreases the amount of audio data sent. By default, Secure Global Desktop uses Medium Quality Audio. This should be sufficient in most cases. The sample rates are: Low Quality Audio - 8kHz Medium Quality Audio - 22.05kHz High Quality Audio - same as medium (this is a Terminal Services restriction)
Audio: Enable UNIX audio service	`--array-unixaudio 1 \| 0`	Whether to enable UNIX audio services across the array. Audio is only available for X applications. The audio module of the Sun Secure Global Desktop Enhancement Module must be installed and running on the application server. Changes to this attribute only take effect for new webtop sessions.
Audio: UNIX audio sound quality	`--array-unixaudio-quality low \| medium \| high`	The sample rate of the audio data. Adjusting the audio quality increases or decreases the amount of audio data sent. By default, Secure Global Desktop uses Medium Quality Audio. This should be sufficient in most cases. The sample rates are: Low Quality Audio - 8kHz Medium Quality Audio - 22.05kHz High Quality Audio - 44.1kHz
Smart card: Enable smart card service	`--array-scard 1 \| 0`	Whether to enable smart card services across the array. Support for smart cards is only available for applications running on a Microsoft Windows Server 2003 application server. Changes to this attribute only take effect for new webtop sessions.
Profile Editing: Enable user profile editing	`--array-editprofile 1 \| 0`	Whether to allow users to create or edit their own profiles for use with the Secure Global Desktop Client. By default, profile editing is enabled. If profile editing is disabled, it is disabled for all users, including Secure Global Desktop Administrators. However, Secure Global Desktop Administrators can still create and edit profiles using the Profile Editor application. Profile editing for individual users can be enabled and disabled using the Profile Editing attribute for organization, organizational unit or person objects in Object Manager Changes to this attribute only take effect for new webtop sessions.
Clipboard: Enable copy and paste	`--array-clipboard-enabled 1 \| 0`	Whether to allow copy and paste operations for Windows and X application emulator sessions across the array. By default, copy and paste is allowed. Copy and paste operations for individual users can be enabled and disabled using the Clipboard Access attribute for organization, organizational unit or person objects in Object Manager Changes to this attribute only take effect for new emulator sessions.
Clipboard: Client security level	`--array-clipboard-clientlevel`	The security level for Secure Global Desktop clients. Used to control copy and paste operations between Windows or X application emulator sessions and applications running on the client device. The security level can be any positive integer. The higher the number, the higher the security level. The default security level is 3. Use `-1` on the command line to disable copy and paste operations with applications running on the client. Changes to this attribute only take effect for new emulator sessions.
Serial Port: Enable serial port mapping	`--array-serialport 1 \| 0`	Whether to enable access to serial ports across the array, see configuring access to serial ports for details. By default, access to serial ports is allowed. Access to serial ports for individual users can be enabled and disabled using the Serial Port Mapping attribute for organization, organizational unit or person objects in Object Manager Changes to this attribute only take effect for new webtop sessions.
