UNIX System Resource Usage Considerations

The Entire Net-Work service, Kernels, and clients use UNIX resources. This document describes the use of TCP/IP sockets, threads, and semaphores by the various Entire Net-Work components in UNIX environments.

Entire Net-Work system resources are allocated dynamically, as they are needed, not when the products are started. However, you may encounter times when Kernels are so heavily used that they cannot accept new connections, incoming clients, or System Management Hub (SMH) inquiries. This can also happen when other applications on your system are used heavily.

UNIX systems are sometimes configured with specific platform resource defaults. You must take into consideration how many resources the individual applications require and configure their systems accordingly. Bear in mind:

This document provides information on Entire Net-Work component resource usage to help you do this:


Entire Net-Work Client System Resource Usage

A simple client uses the following system resources:

Bear in mind that some client applications are complex and may require multiple connections.

Entire Net-Work Kernel System Resource Usage

Entire Net-Work Kernels use the following system resources:

System Management Hub (SMH) System Resource Usage

If SMH needs to retrieve Kernel information from the Software AG Directory Server, another thread, semaphore, and socket are required temporarily. These are freed immediately after the information is obtained.

Software AG Directory Server System Resource Usage

Software AG Directory Server clients use the following system resources:

System Resource Usage Summary Table

The following table summarizes use of system resources by the various Entire Net-Work components.

Component System Resource Requirements Duration of Requirement
Sockets Threads Semaphores
Client data protection 0 1 3 Life of the client.
Client connection (each connection) 1 1 1 Life of the client.

Kernel data protection 0 7 14 Life of the Kernel.
Kernel access (e-business, e-business client, classic Entire Net-Work, and SMH) 1 1 1 Life of the access attempt.
Kernel incoming and outgoing connection (e-business and classic Entire Net-Work) 1 1 1 Life of the connection.
Kernel incoming client 1 1 1 Life of the client.
Kernel retrieval of network information from the Directory Server 1 1 1 Temporarily; resources freed after information is retrieved.
SMH retrieval of Kernel information from the Directory Server 1 1 1 Temporarily; resources freed after information is retrieved.
Directory Server base processing 1 2 6 Life of Directory Server.
Directory Server incoming connection handling 1 2 1 Life of the connection.
