What is the Oracle Secure Global Desktop server configuration estimation proposal, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

As a unified application access layer portal, how should the server configuration of Oracle Secure Global Desktop be estimated? How to determine the CPU and memory configuration of the server? These issues must be considered in the application of Oracle Secure Global Desktop to the production environment.

Before estimating the Oracle Secure Global Desktop server configuration, we first need to understand that there are some factors that we can't take into account in practical applications, or, in other words, there are uncontrollable variables, such as:

The type of application that the user actually runs through SGD: WordPad, Word,Firefox, or xterm

How users use these applications: just read the document, enter text, listen to music or deal with video

These uncontrollable variables will directly affect the resource consumption on the Oracle Secure Global Desktop server. Another example:

Take memory usage: an application that spans four monitors definitely consumes more memory than an application that uses only a single window of 1024x768.

Take the amount of CPU used: applications that display text data, such as video playback, or high-frequency mouse operations, or running animations, obviously consume more CPU.

After understanding the impact of these uncontrollable variables on the estimation, we can further estimate.

Starting from a macro perspective, here are some suggestions for server configuration estimation:

Single SGD server configuration:

Supports up to 500 users

Each user runs two applications with 1920x1200 window size at the same time

Need 192GB memory, CPU of 1*3GHz (815 cores)

SGD Array:

Up to 10 nodes (that is, up to 10 SGD servers in an array)

Supports up to 5000 users

Application server:

Run up to 100 applications

Need 192GB memory, CPU of 1*3GHz (815 cores)

Administrators can choose high-configuration or low-configuration servers

Then from the micro point of view, how is the above conclusion calculated? Continue to look down:

SGD server:

Memory estimation: about 80MB memory per user (running two Windows applications simultaneously)

CPU's estimate: about CPU of 50MHz per user (a typical application uses about 10-30MHz of CPU, but actually CPU usage depends on the application itself. Some busy applications may use 50-100MHz CPU. )

SGD Gateway server:

Estimated memory: approximately 2MB memory per user (detailed formula: JVM memory = (number of applications + 3) x SGD users + number of websocket connections + number of HTTP connections) x 300 KB, and by default, SGD Gateway is configured to support up to 100 simultaneous HTTP connections, 512 Adaptive Network Protocol (AIP) connections and 512 Web Socket connections)

Estimate of CPU: about CPU of 10MHz per user

Finally, it's important to note that these are just rough estimates for "ordinary users"-users who usually use SGD as an office environment to open one or two Office applications at a time for simple text manipulation. This estimation method is only a theoretical data, in the process of practical application, especially in the production environment, but also need to be combined with the actual situation, specific analysis and testing of specific problems, the recommendations of this paper must not be regarded as an accurate measure. no, no, no.
