After you change the configuration parameters either by editing the bpmprocessstore.conf file, or by using the BPM Process Store Configuration interface, you can reload the updated configuration parameters without restarting the server. Business Process Server contains a BPM Process Store utility to do this, in the OEBPS_HOME\bin folder.
For Windows:
bpmProcessStore.cmd refresh
For UNIX:
bpmProcessStore.sh refresh
Note: If you have changed the Batchsize parameter, then you must restart the server to reload it.
