hi,all
I am currently using jbpm4.4 to build my own project, but meet with some problems. please help~many many appriciates~ :)
I don't know much about hibernate, but when the processInstance is started. I want to insert a "key" into a record of the "execution" table.(since this "key" is unused by now. :) someone may tell me how insert this data? I check some of the source code, and know something about PVM, but not understand this totally~ :((
another problem, and I see someone used to posted in the forum, but not yet solved~how can we abtain all the task node of one processInstance??
I check the method createTaskQuery.processInstanceId().list, but this is only to query the active node of task, so the count of the method always is 1.

[jBPM] - Serious performance issue 5.1

Hi,
My use of jBPM 5.1 is a little unusual. I have very simple workflows that take a record, carry out some simple manipulation and return the result at the end of that manipulation as a Parameter Mapping. In rare circumstances a Human Task might be required in the workflow logic to present the errant record for attention by a human. So I might have 1 million records, with maybe 12 that need attention. The remainder are all dealt with by the mvel logic in the workflow and a custom workflow item.
I simply create the StatefulKnowledgeSession and call startProcess for each record. This is killing performance, profiling the method that has the startProcess call is using 99.5% of all CPU time, the rest is mostly outside the workflow and is persisting the altered record to the Db. Is there a better way?
Here is theh basic call code
|
| params.put("transformData", tData); |
|
| params.put("namedCaches", cacheQueries); |
|
|
| ksession.startProcess( "_" + com.example.edm.core.utils.Utils.getRefId(transformationWorkflow.getUuid()), params); |
|
|
| transform = tData.getValues(); |
Thx.
David
