How to change MaxReceivedMessageSize for Client Obejct Model in SharePoint 2010 2013

If you are using SharePoint client Object Model and you need to change max size of the message you need to pass to Client.svc, what you probably need is to increase the default value. This can occour for example if you are uploading files to a remote SharePoint using client object model.

The message you are receiving when executing query with client obejct model should be something similar to this: "The request message is too big. The server does not allow messages larger than 2097152 bytes."

The property is MaxReceivedMessageSize of ClientRequestServiceSettings.

Default value is 2MB (2097152 bytes).

Use this PowerShell script (from SharePoint Management Shell in Administrative mode with a Farm Administrative Account) to change this value.

In the example this is set to 2GB.

$ws = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$ws.ClientRequestServiceSettings.MaxReceivedMessageSize = 2147483647
$ws.Update()

Another option is to create a Farm Scoped Feature with this feature receiver:

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
   SPWebService contentService = SPWebService.ContentService;
   /* Must set this to -1, else, the MaxReceivedMessageSize value for
   SPWebService.ContentService.WcfServiceSettings["client.svc"] will not be used.*/
   contentService.ClientRequestServiceSettings.MaxReceivedMessageSize = -1;
   // SPWcfServiceSettings has other Properties that you can set.
   SPWcfServiceSettings csomWcfSettings = new SPWcfServiceSettings();
   csomWcfSettings.MaxReceivedMessageSize = 2147483647; // 2048MB
   contentService.WcfServiceSettings["client.svc"] = csomWcfSettings;
   contentService.Update();
}

HowTo Clear SharePoint Timer Job Cache

Often during SharePoint development can be usefull to clear Timer Job Cache.
In order to do that we need to do this:

• Stop Windows SharePoint Timer Service from Windows Services
• Open C:\ProgramData\Microsoft\SharePoint\Config\<<GUID>> folder
• Delete all the XML files inside the GUID folder.
• Open the Cache.ini file and change the value to 1.
• Save Cache.ini file
• Restart Windows SharePoint Timer Service from Windows Services

After restarting Windows SharePoint Timer Service you can see that the cache will be repopulate (quite resource expensive activity).

Do that on every SharePoint server in the farm.
