Question

不知何故，我的数据库中没有结束时间的历史流程实例。

条目如下所示：

ACT_HI_PROCINST (ID_, PROC_INST_ID_, BUSINESS_KEY_, END_TIME_)
VALUES ('0c128aec-e6f0-11e6-bc94-5456dbfc2b09', '0c128aec-e6f0-11e6-bc94-5456dbfc2b09', '3bc71b87-7134-4ead-8493-4c0f11d635be', null);

当我尝试使用DELETE HTTP request to the REST interface删除历史流程实例时，会发生以下错误：

ERROR [org.camunda.bpm.engine.context] (default task-7) ENGINE-16004 Exception while closing command context: Process instance is still running, cannot delete historic process instance: 0c128aec-e6f0-11e6-bc94-5456dbfc2b09: instance.getEndTime() is null: org.camunda.bpm.engine.exception.NullValueException: Process instance is still running, cannot delete historic process instance: 0c128aec-e6f0-11e6-bc94-5456dbfc2b09: instance.getEndTime() is null

如何在没有Java或HTTP的结束时间的情况下删除历史流程实例？

Answer 1

流程实例尚未完成。我想你只能删除实例。 https://docs.camunda.org/manual/7.6/reference/rest/process-instance/delete/

您还可以降低数据量较少的历史记录级别https://docs.camunda.org/manual/7.6/user-guide/process-engine/history/#set-the-history-level
