While executing Timers and Async Jobs?</P><P></P><P>The Reason why am i raising this question is, we are running in Dev Environment with one node and also pointing to the same DB from our Local Environment by setting the JobExecutor to True. Due to this we are facing issues with the Async Service Task Jobs. Below is the Exception Scenario:</P><P>When the Job gets created for the Async Service Task in Act_ru_job table,&nbsp;we observed that the Service Task is not getting executed and that entry is getting locked for long time. Also the expiration time is revised (increments every 3 mins)every time the Job gets fired, that gives the ActivitiOptimisticLocking Exception every time.</P><P></P><TABLE class="j-table jiveBorder" style="border: 1px solid #c6c6c6;" width="100%"><THEAD><TR style="background-color: #efefef;"><TH><TABLE border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 816pt;" width="1088"><TBODY><TR style="height: 15.0pt;"><TD height="20" style="height: 15.0pt; width: 48pt;" width="64">ID_</TD><TD style="width: 48pt;" width="64">REV_</TD><TD style="width: 48pt;" width="64">TYPE_</TD><TD style="width: 48pt;" width="64">LOCK_EXP_TIME_</TD><TD style="width: 48pt;" width="64">LOCK_OWNER_</TD><TD style="width: 48pt;" width="64">EXCLUSIVE_</TD><TD style="width: 48pt;" width="64">EXECUTION_ID_</TD><TD style="width: 48pt;" width="64">PROCESS_INSTANCE_ID_</TD><TD style="width: 48pt;" width="64">PROC_DEF_ID_</TD><TD style="width: 48pt;" width="64">RETRIES_</TD><TD style="width: 48pt;" width="64">EXCEPTION_STACK_ID_</TD><TD style="width: 48pt;" width="64">EXCEPTION_MSG_</TD><TD style="width: 48pt;" width="64">DUEDATE_</TD><TD style="width: 48pt;" width="64">REPEAT_</TD><TD style="width: 48pt;" width="64">HANDLER_TYPE_</TD><TD style="width: 48pt;" width="64">HANDLER_CFG_</TD><TD style="width: 48pt;" width="64">TENANT_ID_</TD></TR></TBODY></TABLE></TH></TR><TR style="background-color: #efefef;"><TH><TABLE width="1088"><TBODY><TR><TD width="64">3463484</TD><TD width="64">5</TD><TD width="64">message</TD><TD width="64">11-FEB-18 11.20.19.577000000 PM</TD><TD width="64">57ac5579-c43c-431f-8e12-fb699d314488</TD><TD width="64">0</TD><TD width="64">3463479</TD><TD width="64">3463476</TD><TD width="64">***Process:29:3460040</TD><TD width="64">3</TD><TD width="64"></TD><TD width="64"></TD><TD width="64"></TD><TD width="64"></TD><TD colspan="2" width="128">async-continuation</TD><TD width="64">tenant_1</TD></TR></TBODY></TABLE></TH></TR></THEAD><TBODY><TR><TD><TABLE width="1088"><TBODY><TR><TD width="64">3463486</TD><TD width="64">5</TD><TD width="64">message</TD><TD width="64">11-FEB-18 11.20.22.351000000 PM</TD><TD width="64">57ac5579-c43c-431f-8e12-fb699d314488</TD><TD width="64">0</TD><TD width="64">3463481</TD><TD width="64">3463476</TD><TD width="64">***Process:29:3460040</TD><TD width="64">3</TD><TD width="64"></TD><TD width="64"></TD><TD width="64"></TD><TD width="64"></TD><TD colspan="2" width="128">async-</TD><TD width="64"></TD></TR></TBODY></TABLE></TD></TR></TBODY></TABLE><DIV> </DIV></BODY></HTML> Thu, 15 Feb 2018 04:18:17 GMT abhitorem 2018-02-15T04:18:17Z Need clarification on CreateProcessEngines in Clustered Env https://connect.hyland.com/t5/alfresco-forum/need-clarification-on-createprocessengines-in-clustered-env/m-p/5427#M2680 Hi,We are using Activiti 5.22.x with Spring Integration, below is the code we are using to create the Process Engine<IMG id="smileyfrustrated" class="emoticon emoticon-smileyfrustrated" src="https://migration33.stage.lithium.com/i/smilies/16x16_smiley-frustrated.png" alt="Smiley Frustrated" title="Smiley Frustrated" />pringProcessEngineConfiguration processEngineConfig = new SpringProcessEngineConfiguration();&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;processEngineConfig.setDataSource(activitiDataSource());&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;processEngine Thu, 15 Feb 2018 04:18:17 GMT https://connect.hyland.com/t5/alfresco-forum/need-clarification-on-createprocessengines-in-clustered-env/m-p/5427#M2680 abhitorem 2018-02-15T04:18:17Z Re: Need clarification on CreateProcessEngines in Clustered Env https://connect.hyland.com/t5/alfresco-forum/need-clarification-on-createprocessengines-in-clustered-env/m-p/5428#M2681 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive_macro_quote jive-quote jive_text_macro"><P><SPAN style="color: #727174; background-color: #ffffff;">Will it create the multiple Process Engine with the JobExecutor set to 'True', if 'Yes' will it cause any problems.
