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, true);
When I am trying to undeploy that workflow, its took almost 3 minutes and mean time my UI page timeout happened. When I gone inside of the undeploy, I found some interesting things as below.
1) select queries on ACT_HI_VARINST and ACT_RU_VARIABLE tables. For instance, there are 70*150 *2 (instances * variable count * 2 VAR tables) = 21000 select queries which is consuming most of the execution time (~2/3 of execution time) which can be minimized by considering process_inst_id_ value.
2) After collecting entities using select queries, While deleting Its doing bulk deletes for few tables but not for ACT_RU_VARIABLE and ACT_HI_VARINST tables. Not sure why these 2 tables not considered for bulk deletes using process instance Id which is consuming more time during un deployment.
Is there any other way to do faster un deployment process to avoid UI page timeouts. Attached my use case activiti log file for reference.
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?
