By limiting the number of concurrent calls and sessions on the Web Content Server in System Center 2012 – Service Manager, you can limit the number of resources used by the Self-Service Portal. Use the following procedure to configure the number of concurrent calls and sessions. For more information, see the MSDN article <serviceThrottling> to specify the throttling mechanism of a Windows Communication Foundation (WCF) service.

To configure concurrent calls and sessions

1. Log in to the computer hosting the Web Content Server with administrative privileges.

2. Using a text editor of your choosing (for example, Notepad), open the Web.config file in the %inetroot%\inetpub\wwwroot\System Center Service Manager Portal\servicehost folder.

3. Locate the <serviceBehaviors> section, as shown in the following example:

   <system.serviceModel>  
   <behaviors>  
   <serviceBehaviors>  
   <behavior name="DefaultHttpServiceBehavior">  
   <serviceMetadata httpGetEnabled="true"/>  
   <serviceDebug includeExceptionDetailInFaults="true"/>  
   <dataContractSerializer maxItemsInObjectGraph="2147483647"/>  
   </behavior>  
   <behavior name="DefaultHttpsServiceBehavior">  
   <serviceMetadata httpsGetEnabled="true"/>  
   <serviceDebug includeExceptionDetailInFaults="true"/>  
   <dataContractSerializer maxItemsInObjectGraph="2147483647"/>  
   </behavior>  
   </serviceBehaviors>  
   </behaviors>  
   

4. Add the line <serviceThrottling maxConcurrentCalls="160" maxConcurrentSessions="10000"/> in both the DefaultHttpServiceBehavior and DefaultHttpsServiceBehavior sections, as shown in the following example:

   <system.serviceModel>  
   <behaviors>  
   <serviceBehaviors>  
   <behavior name="DefaultHttpServiceBehavior">  
   <serviceMetadata httpGetEnabled="true"/>  
   <serviceThrottling maxConcurrentCalls="160" maxConcurrentSessions="10000"/>  
   <serviceDebug includeExceptionDetailInFaults="true"/>  
   <dataContractSerializer maxItemsInObjectGraph="2147483647"/>  
   </behavior>  
   <behavior name="DefaultHttpsServiceBehavior">  
   <serviceMetadata httpsGetEnabled="true"/>  
   <serviceDebug includeExceptionDetailInFaults="true"/>  
   <serviceThrottling maxConcurrentCalls="160" maxConcurrentSessions="10000"/>  
   <dataContractSerializer maxItemsInObjectGraph="2147483647"/>  
   </behavior>  
   </serviceBehaviors>  
   </behaviors>  
   

5. Close your text editor, and save the changes.
