Prior to version 8.5, IBM BPM supported a stand-alone Process Center profile, and it was provided as part of the typical installation option. In IBM BPM V8.5 Standard and Advanced, a typical installation now creates a single cluster network deployment Process Center profile. The stand-alone profile is now only provided with the IBM Integration Designer unit test environment installation and with IBM BPM Express.
