Network Bandwidth Utilization - Enable Response Compression Filter (GZip)

Troubleshooting

Problem

If you are running Maximo Asset Management in a low bandwidth network environment, you can reduce network bandwidth utilization by enabling the data compression filter on the Maximo application server.

Resolving The Problem

If your environment is front ended by an IBM HTTP Server (IHS) or Apache HTTP server, HTTP compression is more efficient than GZip. Please see the Maximo Performance white papers (Maximo 7.5 | Maximo 7.6) for more information.

This section explains how to enable the Data Compression Filter (GZIP) on the Maximo application server to reduce network bandwidth utilization.

Considerations

The data compression filter (GZIP) increases CPU utilization. Specifically, the application server CPU zips the data before sending it across the network and the browser client CPU unzips the data upon receipt before processing it. Enabling data compression trades network utilization for CPU utilization. Therefore, if you are currently experiencing high CPU utilization on any server in the Maximo environment, do not enable data compression.

How to Enable the Data Compression Filter (GZIP)

1. Shut down the Maximo application server.

2. Save a copy of the web.xml file.

3. On the Maximo administrative workstation, open the following file using a text editor:

4. Search for the following comment line in the file:

<!--Uncomment these lines to enable response HttpGZIPFilter

5. Remove the start comment markings (<!--) that precede the comment.

6. Remove the end comment markings (-->) after the last line of filter code </filter> in this code section.

7. Search for the next occurrence of the HttpGZIPFilter comment line:

<!--Uncomment these lines to enable response HttpGZIPFilter

8. Remove the start comment markings (<!--) that precede the comment.

9. Remove the end comment markings (-->) after the last line of filter code </filter-mapping> in this code section.

10. Save the file.

11. Build and redeploy the maximo EAR file.
