How to assign Job-Agent to Web Services?

RayJhong

Hi There,

 

As i know, since RM8, all processes were executed by Job-Agents. My question is if using Web-Service, how to make them executed on a certain Job-Agent? If so, we will be able to set permissions by each queue for users/groups.

 

Things I've tried were, I have a process called "ReadCsv.rmp" deployed as a web service, an there are two queues on my RM8 Server as below:

I'm going to execute "ReadCsv.rmp" by using a user  called "csvusr", which is obviously not existed on each Permitted groups above, and I expected an error or permission deny message. HTTP request shown below:

curl --user csvusr:csvusr123456 --upload-file /Users/user/Desktop/test.csv http://VM-Rapidminer:8080/api/rest/process/ReadCsv?

 But it successfully executed, it seems like processes executed from Web Services does not take permission settings on Queues, and neither do I know which queue execute "ReadCsv.rmp" this process.

 

Back to the subject, I would like to know how to make a web service execute on certain Queue/Job-Agent?

Any suggestion would be appreciated.

 

Sincerely,

Ray Jhong.

Hi Ray,

 

In principal you are correct, that processes are executed by Job-Agents. But as you can see in the attached architecture overview, Web-Services and Web-Apps are execute by the central node. So you have to set the permissions directly for the web service, as there is no job agent involved.

This makes sense, as otherwise you would have slight communication overhead, which could be inconvinient for online applications.
