Users Report "Sticky" or Repeating Keys with Secure Global Desktop 4.7 (Doc ID 1536687.1)

Last updated on DECEMBER 06, 2013

Applies to:

Oracle Secure Global Desktop - Version 4.7 to 4.7 [Release 4.0]
Information in this document applies to any platform.

Symptoms

Users may report that when connecting to a Secure Global Desktop (SGD) 4.7 server and launching Windows or X applications that while typing, keys will start repeating.  This behavior is best explained as a single key stroke acting "sticky" and input continues as if it is held down or has been pressed multiple times.  This behavior is not seen by all users, and further investigation will show that users experiencing the problem will trend towards high latency connections between client and server..

Maximum Round Trip times greater than 0.5 seconds are more likely to see this behavior. 

Note: Administrators who wish to check client-server connections for high latency may use the "ping" command,  from the client to the SGD server or vice versa, e.g.

ping sgdserver.oracle.com
