Using an HTTP server causes duplicate snapshot deployments for IBM Business Process Manager (BPM)



With IBM Business Process Manager, duplicate snapshot installation requests are sent to the Process Server from the Process Center after a 1 minute delay. IBM HTTP Server is used as a web server for the Process Center console. This scenario leads to an additional load on the system, delays, and sometimes installation failures.


Duplicate requests are sent to the Process Center for actions that take longer than 1 minute.
These requests might include items like:

  • Snapshot install
  • Snapshot import/export
  • Snapshot archive

In the SystemOut.log file for the Process Center, there are multiple log messages for the same action 1 minute apart. You see messages similar to the following text:

CWLLG0146I: Beginning export install for snapshot


The default settings for the HTTP Server retry a POST request after 1 minute if a response is not received. Various functions of the Process Center console use HTTP POST requests. Many of these functions can take longer than 1 minute like a snapshot install, import, or export.. IBM Business Process Manager does not support sending multiple POST requests for the same Process Center action.

Resolving The Problem

Tune the HTTP settings to avoid the POST retry requests.
