Presentation Server Variables

(appxd and WinAppxD)


APPX_DISABLE_TCP_NODELAY

Disables the use of the TCP “NODELAY” option. The NODELAY option sends out characters without buffering multiple characters into a single packet. Buffering is what normally takes place. Disabling NODELAY may improve your APPX Presentation Client or APPX/Net performance. (It also may not. Results are dependent on your network configuration and what is happening across the network.)

Valid values: 1

Default value: not set

 

APPX_NET_FEATURE_MASK

Allows you to hard code a list of supported client/server features, in case you want to override the client or server’s default list. For example, if both your client and server support the new Data Palette feature, but you do not want to make this feature available, you can disable it by eliminating the bit representing that feature from the feature mask on the client or server. This variable should be used only as directed by APPX Technical Support.

Valid values: hex numbers between 0x00000000 and 0xFFFFFFFF

Default value: APPX version-dependent

 

APPX_SERVER

Must be set to a valid filename of an APPX engine. For example, if APPX is installed in /usr/appx, set APPX_SERVER=/usr/appx/appx. On Unix systems, in most cases, this variable should be set in the start-appxd.sh shell script. On Windows systems, set it in the System environment variables dialog box. This variable must be set before appxd or WinAppxD is started. Changes made to it when appxd and WinAppxD are already running will be ignored until appxd or WinAppxD is killed and restarted.

Valid values: valid path to an APPX engine

Default value: not set

 

APPX_SRVR_TIMEOUT

Specifies the interval in minutes between server pings asking “is the other system alive?” in an attempt to detect dead connections. The default is 10. If you set it to a number below 5, APPX will reset it to 5 to avoid filling the network with constant “are you there?” queries.

Valid values: integers

Default value: 10
