Is the IOrganizationService.Execute method thread safe within a plugin?

(0) ShareShare

Posted on by Community Member

Currently working on a CRM 2016 onprem system but trying code for CRM Online whenever possible.

I would like to Execute several CRM Actions via the IOrganizationService.Execute method from within a CRM WFA using asynchronous Tasks so that my wait time is closer to that of the longest running action rather than the sum runtimes for all of the actions.

Does anyone know if the concrete implementation of IOrganizationService  returned from the plugin IOrganizationServiceFactory is thread safe? 

Alternately has anyone had success using the IOrganizationFactory to spin up multiple IOrganizationService objects within a plugin?

Thanks,

Scott Colson

    Hello,

    Yes it is thread safe. The IOrganizationService itself is just an interface but, the implementation you get from the OrganizationFactory is thread safe inside of the CRM context.

      

    Please keep in mind the following though:

    When CRM calls the Execute method on a your plugin or custom workflow activity (not the Execute method of the organization service) it will only create one instance of your IPlugin class or CodeActivity class

    You have to make sure your own Execute method is thread safe!

    On the same instance of your class CRM will try to call your Execute method multiple times, when needed.

      

    The IOrganizationFactory implementation will happily create new instances of the OrganizationService for you, which are thread safe.

      

    Hope this helps you. If you have any other questions, please let me know! :-)

    Thank you Michel. I'll spin up additional org services and split the action executions across those.

    Hello,

    this is not true, at least in a trial environment (I don't think production will be different) on version 1710 (9.1.0.1467) online.

    I have tried to create multiple instances of OrganizationService from a Custom Workflow Activity called by an Action, to use them for same parallel calls to the SaveChanges method (on new instances of OrganizationServiceContext), but the result is that they are serialized, this is the trace:

    ####2019-01-25 17:38:41.4601 534 DEBUG - SaveChanges 334ms

    ####2019-01-25 17:39:10.6275 513 DEBUG - SaveChanges 29439ms

    the same trace on my machine using OrganizationServiceProxy is this:

    ####2019-01-25 18:19:01.4624 21 DEBUG - SaveChanges 3677ms

    ####2019-01-25 18:19:02.0897 22 DEBUG - SaveChanges 4304ms

    And if it gets overloaded this is the exception you get:

    Microsoft.Xrm.Sdk.SaveChangesException: An error occured while processing this request. ---> System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: Concurrent calls to Sandbox SDK Listener are not allowed. Please work with plugin owner to make sure multiple SDK calls in parallel are not made to avoid this error.
