Tuning the SGD Gateway for Production Deployments (Doc ID 2075347.1)

Last updated on FEBRUARY 07, 2021

Applies to:

Oracle Secure Global Desktop - Version 5.2 and later
Information in this document applies to any platform.


The Secure Global Desktop (SGD) 5.2 Gateway documentation outlines a hypothetical sizing example with 500 users, each with two applications, resulting in a JVM consuming less than 1 gigabyte of memory. Specifically:

The required JVM memory is:

(2500 + 500 + 300) x 300 kilobytes = 990 megabytes, approximately.


In the /opt/SUNWsgdg/proxy/etc/tuning_parameters file, set the -Xms and -Xmx parameters to the calculated JVM memory value. -Xms and -Xmx are normally set to be the same value for performance reasons.

Administrators of Secure Global Desktop deployments may be interested in better understanding the process of tuning the SGD Gateway for production.  This document provides information on load testing of a single SGD Gateway and contains information on how many users/sessions can be handled per Gateway.
