Re: [Condor-users] Is a worker sub-process created for SOAP requests

[Sateesh Potturu <sateesh.potturu@xxxxxxxxx>]

Hi Dan,

Thanks for the reply.

We have submit, hold, remove, release that are not read-only. All the rest are read-only. But, the frequency of read-only calls is very high.

Regards,
Sateesh

Sateesh,

QUERY_WORKERS is for read-only queries.  Are your SOAP calls to the 
schedd read-only operations?  Or are you updating the queue in some way?

If they are indeed read-only, then it should be possible to fork in the 
handler.  The difficulty of doing this will depend on how the code is 
structured.

1. Is there any work-around to handle collector & schedd taking too 
long in responding to SOAP? Is quill the solution?
2. This (SOAP not using QUERY_WORKERS) will be fixed in upcoming 
releases, right?

Thanks,
Sateesh

Hello All,

We are sometimes observing condor_schedd and condor_collector getting stuck in responding to SOAP requests; some times as high as 5 minutes. The latter caused Startd class ads to get removed as stale ads!!

Do SCHEDD_QUERY_WORKERS and COLLECTOR_QUERY_WORKERS have any impact on SOAP requests? We observed worker sub-processes getting created for a burst of 'condor_q -l' commands. But, did not observe any worker sub-processes getting created for SOAP requests. Are SOAP requests handled in the main condor_schedd/condor_collector processes itself?

Thanks,
Sateesh
    
        

IIRC, SOAP queries are handled in the main processes. I believe this is because the QUERY_WORKER capabilities are implemented within the CEDAR query functions.

I don't think there is any particular reason that the SOAP queries could not use the QUERY_WORKERS.

Best,


matt
