Known Side Effects
WebSphere Application Server traditional
Please refer to Regression List for changes with negative effects.
- 8.5.5.23
- The ability to administer DataPower appliances has been removed from the WebSphere Application Server Administrative Console. See details in PH50841.
- IBM HTTP Server: IBM HTTP Server now limits HTTP request bodies to 1 Gigabyte by default. Previously, there was no limit.
- The limit can be increased by using the LimitRequestBody directive. Users are encouraged to limit such increases using limited scope such as <Location> rather than changing it globally.
- 8.5.5.16
- If a WebSphere application running behind a HTTP proxy server (such as IBM HTTP Server with the WebSphere WebServer Plug-in) further configuration may be required to trust data from the proxy server. See Potential WebSphere Application Server problems when deployed behind a WebSphere-aware proxy server.
