I'm the beginner of Case and workflow management and want to use OpenText CASE360 create a simple task can anyone advise me how to create/design/implement etc.
first have a local set up of case360.
Choose a POC topic for the same. and start to build the components step by step.
starting with Casefolder, Process, Queries.etc
Start to build components individually and then try connecting each of them.
The help document covers every topic in details

In general, I have a single workflow that I want to be able to monitor. The workflow should start whenever new files arrive or alternatively at certain scheduled times, i.e. I want to be able to insert new "jobs" to the workflow as they come, and process the files by going through multiple different tasks and steps. I want to be able to monitor each file going through the tasks.
The queues and distributing the load for each task might be managed by Celery, but it's not decided yet either.
I've looked at Apache Airflow, and as far as I understand at the moment, is geared more towards monitoring many different workflows, such that each workflow is mostly running from start to end, not adding new files to the beginning of the flow before the previous run ended.
Cadence workflow seems like can do what I need, but also seems to be a bit of an overkill.
I'm not expecting a specific final solution here, but I would appreciate suggestions to more such solutions that I can look into and can fit the above.

Extremely light-weight and fast compared to Airflow.
I want to create change request using scripts and not from the GUI page. How can I achieve that ? Also, there is a single sign on check of my organization too.
A few options:-
Create Scripted REST API - this exposes a URL which can be called by an external system. Tricky if you are new to SN.
As #Rafay suggestions - setup a scheduled event. Check out https://community.servicenow.com/community?id=community_question&sys_id=b32c0765db9cdbc01dcaf3231f961984
Scheduled events can be scripted/reports or create templates.
Templates can create of tasks without any coding - may be easier if it meets your requirements? These are referred to as templates and can be created via the UI then scheduled to create them (e.g. A regular server patching activity).
iam facing issue in jbpm as iam new to the jbpm.
i need to re-start the process or need to jump back to the previous process.
can you any one please suggest how to do it
my flow is
before saving, based on condition , i need to repocess the flow from getDeclaration.
can any one guide me to do this.
please let me know, if any extra information needed
Here is an example of how you can return to a previous task.
I'm a jBPM noob running jBPM5.4 in AS7. I have tried posting this question on the jBPM duscussion board, but no luck, so I thought I'd try here on stack.
My Goal: Create the process in guvnor, run it in gwt-console-server, have my java application feed information to the process, and follow the current state in the jbpm Console.
So far, I have installed the jbpm console and console server as well as Guvnor and designer on jBOSS AS7. I am able to create a process in Guvnor and run and monitor that process from the jbpm Console. The missing piece is that I do not understand how to externally insert messages to the process that is running.
Using eclipse and the jBPM example, I can run a process and insert messages, but my goal is to use the jbpm console to monitor the processes.
I assume I need to access the knowledgesession running in the gwt-console-server, but I'm not sure how to do that. Is it safe to access/modify a session that is persisted out to a database (ie, both gwt-console-server and my custom app would be able to modify it) and then the jbpm console would read from it?
I see in the BPM Console reference (https://community.jboss.org/wiki/BPMConsoleReference) that there is an Integration Layer, but there is nothing about how to leverage that - and the like in the doc is broken :(
Can someone point me to an example of an external application feeding messages to a jbpm process that is being monitored by jbpm-console or suggest ways to accomplish this?
Thanks very much for any insight.

PS. I have the new jBPM Developer's Guide, but can't find anything in it to help me with this (so if I am missing something, I can handle a reference back to that guide).
The jBPM console has a REST api that exposes a subset of the functionality. For example, if you model this feeding of information as the start of a process, or the sending of a signal, you could use the signal REST method to send this information to the console for processing.
It's also fine to use an external ksession to update a process instance. As long as they are using the same database to store the information, everything should be fine.
It turns out that the console is just using the logs, so as long as you log to the same DB the console is using (with JPAWorkingMemoryDbLogger) everything pretty much automagically works. You can use either JBPMHelper.newStatefulKnowledgeSession(kbase) or JBPMHelper.loadStatefulKnowledgeSession(kbase, sessionId) depending on if you want to use the knowledge session started from the Console. Also, if you borrow the Console's session, don't dispose it of course.
I read somewhere that you can give the session a business id (and soon do the same from your own code so that they automatically use the same session), but currently when I want to borrow the Console's session I use a kludge that just assumes the highest session is the one I want (it will be as long as the console is already running).
I'm trying to understand how and when tasks are cleaned up in celery. From looking at the task docs I see that:
Old results will be cleaned automatically, based on the
CELERY_TASK_RESULT_EXPIRES setting. By default this is set to expire
after 1 day: if you have a very busy cluster you should lower this
value.
But this quote is from the RabbitMQ Result Backend section and I do not see any similar text in the Database Backend section. So my question is: is there a backend agnostic approach I can take for old task clean-up with celery and if not is there a DB Backend specific approach I should take? Incase it makes any difference I'm using django-celery. Thanks.
If you click on the link to the setting doc for CELERY_TASK_RESULT_EXPIRES:
http://docs.celeryproject.org/en/latest/userguide/configuration.html#result-expires
It does say that database supports this, but then you need to run celery beat (there's a default periodic task, called every day, to remove expired results).
The backend docs in the task should probably mention this as well, maybe there should be a dedicated guide for backends too. If you want to lobby for this, then please open up an issue at https://github.com/celery/celery/issues
