HP-UX OS Socket Buffer Tuning for Coherence
(Doc ID 1322836.1)
Last updated on JANUARY 30, 2022
Applies to:Oracle Coherence - Version 3.3.0 and later
Information in this document applies to any platform.
According to the Performance Tuning Guide:
To help minimization of packet loss, the OS socket buffers need to be large enough to handle the incoming network traffic while your Java application is paused during garbage collection. By default Coherence will attempt to allocate a socket buffer of 2MB. If your OS is not configured to allow for large buffers Coherence will utilize smaller buffers. Most versions of Unix have a very low default buffer limit, which should be increased to at least 2MB.
This document explains the OS parameters to allow larger buffers in HP-UX.
