Deleting central workers in 10.60
We're testing 10.60 and the central guide indicates you can't delete central workers from the central page.
I'm wondering how we go about the situation where you want to delete one from central. Theres no mention of how you can delete them that I can see.
Have you uninstalled the RAS software from the Central? Or try stopping the RAS service, this might allow you to disable it in the workers page and then delete.
Tried that, the delete icon is greyed out if the worker is enabled or disabled. The ras servers can be deleted fine. This is only specific to 10.60 as the functionality is fine in 10.51.
I tested it on a fresh environment as well, I created a cluster of two nodes, uninstalled central from one of them then disabled the worker and checked to see if I could delete it. Which I couldn't, removing the row from the oo_worker_nodes table removes them but I'm sure theres a safer way.
I'm sorry - I only noticed now that you was referring to the Central worker, not the RASes.
So, correct, you can't remove a Central worker. unlike OO9, in OO10x the Central contains an internal worker. As you don't have to install it separately explicitly, you also don't suppose to delete it. It's internal.
If you don't want flows to run on the Central machine, you simply Disable it. It will not consume any resources.
Indeed, removing the record from the DB is not safe.. I wouldn't recommend that.
BTW, why is it important for you to remove this worker?
Ah well I performed an install of a central + ras, the ras component failed as I'd not specificied ras connection credentials, so I foolishly uninstalled and reran the install and now have a duplicate central worker. So its just a requirement to tidy up the duplicate.
In central 10.60 you can delete external workers (RAS workers) only when they are in shut down state. By shut down state it means that either the worker service/process is down or that the worker was uninstalled. The state is highlighted by the cloud with the x icon. Once the topology screen shows the worker in this state select it and delete it. The working status of the worker (enabled/disabled) is not relevant for deletion, that only controls wether flow executions will be assigned to the worker or not.
This works for both regular RASes and reverse RASes.
