Undeploying workflow taking long time

swamy2156 — Thu, 11 May 2017 11:57:13 GMT

Hi, I am using Activiti v5.21 with Oracle 11g RAC database and I have a real time workflow with 70 active instances(in least case) and each process instance consists of 150 variables of each processInstance. I am using API call to delete deployment - repositoryService.deleteDeployment(deploymentId,

Is it completely necessary to have 150 process variables?

Best practice says that you carry the minimum data to orchestrate the process in the instance, all other data should be retrieved as necessary from a system of record and discarded immediately.

Seems this is the root cause of your problem.

Thank you very much for your reply. What is a System of record? and Please explain me in detail(please don't mind) how I can use it. In my case, Workflow consists of 20 form variables but the other variables are configurable data(may be specific to each request) priority color, email fields, auto reassign task to some one if actually assigned user not responded for a particular time. All these data are varied for each request and all this data comes through xml format. How do we can handle these configurable data through System of Record?

Here is a pretty decent description of process solutions and SOR.

One thing I understand is that we can achieve this using store entity task feature as per this blog(https://community.alfresco.com/community/bpm/blog/2016/11/17/activiti-enterprise-developer-series-custom-data-models ). But I couldn't see this activity in the version I am using Activiti community version 5.21. Is this not available in Activiti community edition? Does this available in Activiti v6?

thanks,

Swamy.

Data models are an Enterprise Only feature.

You can achieve pretty much the same thing (just without the tooling integration) using JPA Entities (which is all data models do anyway).

JPA is well documented in the Activiti Community Edition Users Guide here: Activiti User Guide - JPA

As a best practice, only data required to orchestrate the process logic and to retrieve data used in services and forms should be stored in the process, everything else should be retrieved as needed.

There are many good books on the subject.
