not enough physical memory is available to power on this virtual machine

This error occurred to me on VMware when I installed the latest windows 8.1 update on my machine.

 

I have found few solutions for that.

  • First try the VMWare with run as administrator.(In my case this worked)
  • Uninstall the recent update.

We apologize for any inconvenience, but we've made the site read only while we're making some improvements

This message shows when I accidentally close my backup script of the SharePoint site. This massage is prompted by the SharePoint when  a site is in a maintenance mode.

Resolutions

Method 1

image

  1. Go to the central administrator
  2. Application management –> Site Collection Quotas and Locks
  3. Select the site collection and change the locks information to Not Locked.

Some times this page looks like disabled thus you need to try the method two.

Method 2

$Admin = new-object Microsoft.SharePoint.Administration.SPSiteAdministration('https://www.site/sites/sitecollection')
$Admin.ClearMaintenanceMode()

This PowerShell Script changes the site collection back to normal.

How to initialize the SharePoint Client Context in SharePoint Apps (Provider Hosted / SharePoint Hosted) using JSOM (JavaScript Object Model)

 

SharePoint Provider Hosted Apps

First of all we need to understand the SharePoint Provider Hosted hosting blocks.

Provider hosted involves two hosting domains (ex host, sphost). thus request sending to host to sphost considering as cross domain request.

For cross domain request we need to provide SPAppWebUrl to initialize the context. SPAppWebUrl  is available in Url.

Ex:-

https://host.azurewebsites.net/pages/default.aspx?SPHostUrl=https:%2F%2Fsphost.sharepoint.com%2Fsites%2app&SPLanguage=en-US&SPClientTag=0&SPProductNumber=16.0.3417.1223&SPAppWebUrl=https:%2F%2Fsphost-265535272e9c8d.sharepoint.com%2Fsites%2Fapp%2FSample&Source=https://app.azurewebsites.net/pages/default

we can get AppWebUrl by accessing Url parameter. following shows a utility function for getting Url parameter.

function getQueryStringParameter (paramToRetrieve) = {
    var params = document.URL.split("?")[1].split("&");
    for (var i = 0; i < params.length; i = i + 1) {
        var singleParam = params[i].split("=");
        if (singleParam[0] == paramToRetrieve)
            return singleParam[1];
    }
    return "";
};

This will initiate the client context using remote web Url.



var spAppWebUrl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl"));
var ctx = new SP.ClientContext(spAppWebUrl);
var factory = new SP.ProxyWebRequestExecutorFactory(spAppWebUrl);
ctx.set_webRequestExecutorFactory(factory);
var web = ctx.get_web();
 
ctx.executeQueryAsync(
    function () {
           alert("sucess"); },
    function (a, b) {
           alert("error");  }
);

 


SharePoint Hosted Apps


SharePoint Hosted app does not have separate hosting server. SharePoint hosted apps run on the same SharePoint server. thus client context initialization does not need to provide the Url.



var ctx = new SP.ClientContext.get_current();
var web = _sa.ctx.get_web();
ctx.executeQueryAsync(
    function () {
           alert("sucess"); },
    function (a, b) {
           alert("error");  }
);

Working with SharePoint folder properties using CSOM (Client Side Object model ) in SharePoint 2013

 

Accessing folder properties are but different from  SharePoint list item access. Following code demonstrates  the basics.

Create SharePoint Folder with Properties

using (var clientContext = ypurMethodToGetSpContectt() )
{
 
    var lst = clientContext.Web.Lists.GetByTitle("ListName");
    var folder = lst.RootFolder.Folders.Add("FolderName");
    
    folder.Properties["property1"] = "sample";
    folder.Properties["property1"] = "sample";
 
    folder.Update();
    clientContext.ExecuteQuery();
 
}
