Abstract

A method, system and apparatus for autonomic buffer configuration. In accordance with the present invention, an autonomic buffer configuration method can include monitoring data flowing through buffers in a communications system and recording in at least one buffer profile different data sizes for different ones of the data flowing through the buffers during an established interval of time. An optimal buffer size can be computed based upon a specification of a required percentage of times a buffer must be able to accommodate data of a particular size. Subsequently, at least one of the buffers can be re-sized without re-initializing the at least one resized buffer.

Claims

1. An autonomic buffer configuration method comprising the steps of:

monitoring data flowing through buffers in a communications system;

recording in at least one buffer profile different data sizes for different ones of said data flowing through said buffers during an established interval of time;

computing an optimal buffer size based upon a specification of a required percentage of times a buffer must be able to accommodate data of a particular size; and

,

re-sizing at least one of said buffers without re-initializing said at least one resized buffer.

2. The method of claim 1, wherein said recording step further comprises varying delays between consecutive input/output operations in said communications system to affect how much data flows between said communications system and an application coupled to said communications system.

3. The method of claim 1, wherein said monitoring step comprises the step of monitoring said data for each connection in said communications system.

4. A machine readable storage having stored thereon a computer program for autonomic buffer configuration, the computer program comprising a routine set of instructions which when executed by the machine cause the machine to perform the steps of:

monitoring data flowing through buffers in a communications system;

recording in at least one buffer profile different data sizes for different ones of said data flowing through said buffers during an established interval of time;

computing an optimal buffer size based upon a specification of a required percentage of times a buffer must be able to accommodate data of a particular size; and

,

re-sizing at least one of said buffers without re-initializing said at least one resized buffer.

5. The machine readable storage of claim 4, wherein said recording step further comprises varying delays between consecutive input/output operations in said communications system to affect how much data flows between said communications system and an application coupled to said communications system.

6. The machine readable storage of claim 4, wherein said monitoring step comprises the step of monitoring said data for each connection in said communications system.
