How to use two CrmServiceClient to connect with two CRM instances?

(1) ShareShare

Posted on by Pradip Raj 327

Hello Friends,

Currently I am trying to copy data from one crm instance to another using CrmServiceClient, ASP.NET C#. But when I create two objects of

CrmServiceClient, only first instance object (primary endpoint) will be taken into consideration as a connection for the application. It is not taking second CrmServiceClient object to insert data. Actually it is inserting data in the instance from which it was copying data.

Could you please let me know why I am not able to use second CrmServiceClient object to insert copied data or how to change primary endpoints ?

Many Thanks,

Pradip

    Hello,

    Try to add RequireNewInstance=True to connection string you use in constructor of CrmServiceClient

    Hi Andrii,

    you want me to set "useUniqueInstance=true" in CrmServiceClient constructor . Right?

    Thanks,

    Pradip

    I meant what I meant.

    Can you please provide code that you use to instantiate CrmServiceClient instances?

    And my name is Andrii. Not Andri.

    Code :

    IOrganizationService _orgService;

    1)

    CrmServiceClient conn = new CrmServiceClient(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

     _orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

    2)

    IOrganizationService _orgService2;

    CrmServiceClient conn2 = new CrmServiceClient(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

     _orgService2= (IOrganizationService)conn2.OrganizationWebProxyClient != null ? (IOrganizationService)conn2.OrganizationWebProxyClient : (IOrganizationService)conn2.OrganizationServiceProxy;

    I am fetching data from first instance then inserting(creating) in another instance.

    orgService2.Create(entity); // entity is a collection of records.

    Let me know if you need any further information.

    Thanks,

    Pradip

    Am I right that you use the same connection string for both connections - ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString

    The same connection string means the same organization to work with. Correct me if I wrong.

    Sorry its my mistake.

    Correct one :

    CrmServiceClient conn2 = new CrmServiceClient(ConfigurationManager.ConnectionStrings["ConnectionString1"].ConnectionString);

    Both the instances connection strings are added in web.config.

    All the instances for both the organization are different. Still not able to insert in second instance.

    So as I suggested before - add RequireNewInstance=True inside your both connection strings like:

     <connectionStrings>

       <add name="CRMConnectionString" connectionString="Url=orgname.crm.dynamics.com; Username=user@domain.onmicrosoft.com; Password=password; AuthType=Office365; RequireNewInstance=True;" />

     </connectionStrings>

    Hi Andrii,

    You are right. Thank you so much for all your help.

    Also we can set "useUniqueInstance: true" in CrmServiceClient constructor.

    CrmServiceClient crmSvc = new CrmServiceClient("SourceOrgUsername", CrmServiceClient.MakeSecureString("SourceOrgPassword"), "IND", "SFW", useUniqueInstance: true, useSsl: false, isOffice365: true);

    Many Thanks,

    Pradip
