If you are working with Activiti workflows on Alfresco, here are some quick tips I found and I hope can save you some time.Delete workflow instancesWhen you are in the development phase, usually you will have lots of workflows started, but not always finished.If you want to remove all the running workflow instances, you can use a simple command in the workflow console (http://server:8080/alfresco/faces/jsp/admin/workflow-console.jsp)delete all workflows imeanitBut there is a problem with this command.It won't remove the workflow historical registers on database, and you can find some problems accessing your completed tasks after you undeploy your old workflow definitions.This is a bug, and it wasn't fixed until 4.2.f, as described here https://issues.alfresco.com/jira/browse/ALF-20522All you need to do is to run a delete on the database to delete all historic data for no existing workflow definitions:delete from ACT_HI_TASKINST where not exists (select pd.ID_ from ACT_RE_PROCDEF pd where pd.ID_ = PROC_DEF_ID_);Avoid having users starting your custom workflowsIf you created custom workflows, but you are starting then using code, so maybe it's a good idea to hide those workflows in the Start Workflow form.This can be done including the following section into your share-config-custom.xml file:<config condition="Workflow" evaluator="string-compare"> <hidden-workflows> <workflow name="activiti$workflowId"></workflow> </hidden-workflows></config> If you are following this Alfresco issue https://issues.alfresco.com/jira/browse/ALF-21133, then you know Alfresco's accidentally removed all the administration console when they removed the Alfresco Explorer interface, on 5.0.bBut yesterday I saw these messages from on the issue comments history:Kevin Roast added a comment - Yesterday Implementation of consoles for a community admin console will be merged to HEAD shortly. Should appear in a nightly build in the next few days. and thenKevin Roast added a comment - 10 hours ago - edited http://dev.alfresco.com/downloads/nightly/dist/navigate to /alfresco as usual and you will see a new link:Alfresco Administration Console (admin only)Navigate to that and you will see the Community Admin Console! Including a basic System Information page plus the 3 interpreter consoles and Node Browser component available.I decided to download the nightly build and try it to see what exactly they he was talking about, and I saw this:Alfresco's index page: Alfresco Administration Console (with some basic server information): Model and Messages Console (I didn't know this console): Tenant Console:Workflow Console: And a brand new Node Browser: Nao tem como nao dizer que isso enche o saco nao e mesmo? Voce esta no sofa assistindo seu programa favorito, ou um filme super interessante, quando vem o intervalo, aquela desgraca demorada com mais propaganda do que eu com cabelo.Ta certo que as vezes esses intervalos ajudam, segurando um pouco mais a programacao para que de tempo de (chegar em casa, sua mae estender a roupa, chegar ate a sala, usar o banheiro, fazer um lanchinho, arrotar o abecedario), mas quando voce nao precisa fazer nada disso, voce fica muito puto(desculpem nao achei palavra melhor), porque, ficar esperando e uma merda. Esses intervalos tem sempre que ter a mesma duracao, independente do numero de propagandas, mas como se ja nao bastasse ser chato pra caramba, ainda tem vezes que falta propaganda diferente, e passa duas vezes a mesma, DUAS VEZES A
