How to disable Parallel processes execution on Job Service

Do you use a sync project or a script to talk to the target system? If it is a script you can just use the ScriptExecSingle(32) task. It ensures that a specific process step is serialized inside of one queue.

Another option is to set the number of execution slot for the queue running your jobs to 1 for the slot type you are using (internal, external or external32).

Hi Markus,

For custom TS generally I use the custom scrupt "UNSAccountB_'TSname'_Insert", "UNSAccountB_'TSname'_update", etc.

This means that I should be change the VI_UnsAccountB_Generic process.

I think that the most easy way, is to have a dedicated job service with 1 for the slot type.

I see that the default are: External32 slot =4  - External=10 - Internal = 20.

Could you explain me what is the difference from internal and external ?

Thank you very mcuh and best regards

The process tasks used in the process steps are configured to run either as an external process, started by the Job Service or as a thread internally. And you can configure for each slot type how many of each type the Job Service handles concurrently.

Markus Weiss-Ehlers Is it possible to accomplish this with a powershell script as well? I do not see a powershellcomponent option to exec single.

No, there are no special ...Single... tasks for the PowerShell or the PowerShellComponent4. But you can either set up a special queue for handling these jobs where the external slot number is set to 1 or you set the max. instance property of the process task to 1. But be aware that this is then a global setting.
