Oracle Secure Global Desktop 5.4 HTML5 Client slow performance with RHEL 7 Desktop after RHEL April 2019 Patches are installed (Doc ID 2558226.1)

Last updated on DECEMBER 23, 2020

Applies to:

Oracle Secure Global Desktop - Version 5.4 and later
Information in this document applies to any platform.


Users are accessing RHEL 7 Desktop via Secure Global Desktop (SGD) HTML5 client.  They find that the performance significantly declines after installing RHEL 7 April 2019 Patches. The login to the HTML5 Client is fine but when the RHEL Desktop is launched, any interaction with it e.g right click to bring up the right click menu, (create new folder, launch terminal window, etc). takes more time than before, or even typing in a terminal window is slow.

This issue has not been reported with the SGD Java Client or accessing the Desktop outside of SGD.

mesa-dri-drivers.x86_64 18.0.5-4.el7_6
