Creating Workflow Task Programmatically

Jacob HoferDec 17 2024

I am creating tasks using APEX_HUMAN_TASK.CREATE_TASK.

I can successfully create the tasks, but I want to associate the tasks with an active workflow, and am unsure how to do so.

The tasks are being created from a custom plugin that is part of the workflow, via the execution function:

FUNCTION f_create_tasks (
    p_process IN APEX_PLUGIN.t_process,
    p_plugin IN APEX_PLUGIN.t_plugin 
) RETURN APEX_PLUGIN.t_process_exec_result IS
BEGIN
	-- The tasks are to be created here
END;

I am not sure if this is even possible, but I want to be able to easily keep track of associated tasks, with the idea being that all tasks must be completed (but in any order) for the plugin to be completed and for the workflow to continue. I would prefer to not create an extra table, especially since the apex_tasks table already has a workflow_id column I could use to group the tasks together.

Thanks!

Do you have a MOS account? You can see the solution here:

https://support.oracle.com/knowledge/Oracle%20Cloud/2767882_1.html

BTW the toad behavior is normal and I usually choose rollback.

No, I don't have. Can you please copy paste the solution? Thanks.

James Su Feb 15 2025

Please leave an email address.

ronald_2017 Feb 15 2025

I log in. However, it asks Support Identifier. What should I write?

Thanks

You need to purchase the service to see the content.

I may be able to help you in private but if you don't want to post your email I have no way to contact you.

ronald_2017 Feb 16 2025

First of all thanks for your help. My words are not for you. The illogical thing is why should I purchase the service in order to solve the problem which caused by Oracle. What is Oracle support is used for? Besides, it used to be send dm in Oracle forum. Apparently, it is not active now. These kinds of restrictions are really ridiculous in today's world.

Oracle support is for paying customers. Like most businesses, not everything is free.

A part of the contract with having support is that customers are not permitted to share the content that is given within support anywhere in public, hence why James cannot post the solution for you here.

For that error you're getting though, it's a bit of a deceptive message. You may want to look at your Firewall (or get your network guys to) as that's a likely cause.

After I login, I am redirected to registration page. I don't think it is related to firewall. It is written “Connect your User Account” and there is an item called Support Identifier. What should I type there?

Thanks.

I believe that BluShadow is talking about the error you're getting in toad there, not your issues with oracle support.

BluShadow Feb 17 2025

Indeed, I'm referring to the ORA-24757: duplicate transaction identifier
I'm not trying to tell you how to get into Oracle Support. For that you would need to have a customer support identifier CSID which you only get when you pay for support. If you're working for a company then maybe your company has support with Oracle? In which case your company would have someone who is the support administrator and can assign your login to have support with Oracle (they will tie up your login with the company's support identifier for you). In many companies this is a DBA who has this access.

ronald_2017 Feb 17 2025

First of all thanks for your support. The thing is, even I just select via db link I get ORA-24757 duplicate transaction identifier error. I didn't do any DML. I use it in my laptop, not for the company. It is for the educational purposes. Where should I check in firewall?

Cookiemonster76 Feb 17 2025

So where are these two DB's that you're linking together?

Is one of them on your laptop?

ronald_2017 Feb 17 2025

One is in my laptop. It is a test db. The other one is in my friend's virtual windows server. Maybe somethings need to be changed in the virtual server.

What do you recommend? Thanks.

Cookiemonster76 5 days ago

Any and all firewalls between your laptop and the virtual windows server need to have the port(s) you're trying to use completely open.

Alternatively stop trying to link those 2 DBs.

Is there a specific reason you need to link to that DB?

If you're just trying out how DB links work you could just create a loopback link (one that connects to the same DB).

ronald_2017 3 days ago

Yes, I want to use dblink between each other. I just recreated the db link as shared this time. However, it gives another error. It works at first but then gives an error.

ronald_2017 3 days ago

I am just wondering that should I replace 'localhost' in the server's listener file with the server's IP address?
