Waiting for a scheduler in DCC

Distributed Computing Cluster

Hi all

I have a problem with the DCC. I created a cluster with 3 members, 2 worker and a scheduler. In a workflow I sent a job to make pages and OCR. When I put the 3 members as a worker, all the works went to the main host. So, I made this host only a scheduler with the other 2 workers.

I run a new job with the Workflow. As you can see, the task 9 is on course.

The configuration is 2 workers, the other one is no availabe to run jobs.

The job beguns... or at least looks like beguns...

If I went to the taks, the job is on "waiting for a scheduler"

I don't know if I need to configure the other host as a scheduler or miss something in the configuration... but this jobs his waiting and no longer works...

Thanks in advance.

Pd. Sorry for the images, my installation is in spanish... I don't know if the state is waiting for a scheduler...

It sounds like your installation is only licensed for one worker. The license should indicate how many workers you're licensed for (or there should be a message in the event viewer when the service starts).

Hello

This is how my LFDS had the licenses:

How I configure the workers with a license to "work"? Because in the installation, only for the scheduler ask for a license...

Unfortunately these screenshots don't have that information. On the scheduler, restart the DCC service, then look in the Windows event log under Applications and Services\Laserfiche\DistributingComputingCluster\Admin.

You should see something like this:

Laserfiche Distributed Computing Cluster Service started successfully.

Laserfiche Distributed Computing Cluster Service started successfully.

The maximum number of nodes should indicate how many workers are allowed.

It's say that I have 9, but only one Worker "work"
