Where is the SharePoint object cache stored??

  • Where is the SharePoint object cache stored?? Vamsi

    We have experienced a strange issue in SharePoint. We backed-up and restored a site collection from WebApp1 to WebApp2 and both the site collections have Publishing Features activated (BLOB CACHE was NOT Enabled)

    After successful restore , none of the sites were working. Following Exception has occured :

    Site id <> could not be found OR File not found

    Solution :

    In the stack trace there method sitecachesettings(guid id).....Reset the IIS, and booom every thing works fine :)

    My Question :

    Where is object cache stored ??? how it works?? point me any links where I can dig in deep


  • The SharePoint object cache is stored in memory, which is why an IISReset clears it down. Depending on how you restored the site, I'd probably expect to need to do an IISReset after such an admin operation.

  • I have a SharePoint 2007 Publishing Site. The top level site is purely anonymous and one of the children is using Forms authentication using Custom membership provider.

  • Just wanted to see what the consensus on this one is… If you make a call to the OM to return a SP object e.g. SPListItemCollection, and then want to cache the results (to improve subsequent performance and usage of the object/data) would you "unpack" the contents of the collection/object into a custom class and cache that or just cache the native SP object? I’m not sure if there is any reason to introduce the overhead of a custom class etc?

  • I have recently generated a couple of ListDefinitions using both SPSource and VSeWSS SharePoint Solution Generator. In both cases, surpisingly, Visual Studio reports fake schema validation errors in schema.xml like The 'Description' attribute is not declared" for List xmlns="http://schemas.microsoft.com/sharepoint/" BaseType="0" DefaultItemOpen="0" Description=""... >... followed by errors like Could not find schema information for the element 'http://schemas.microsoft.com/sharepoint/:GetVar'. Can anyone help me fix that?

  • We have 3 front-end servers each running multiple web applications. Each web application has an in memory cache. Recreating the cache is very expensive (>1 min). Therefore we repopulate it using a web service call to each web application on each front-end server every 5 minutes. The main problem with this setup is maintaining the target list for updating and the cost of creating the cache several times every few minutes. We are considering using AppFabric or something similar but I am unsure how time consuming it is to get up and running. How do you/would you update an expensive

  • I have run into a problem several times now where I have developed a custom timer job, and I want my site collection administrators to manage the schedule of this job with a custom application page but I keep running into security related obstacles. Since timerjobs are child objects of SPWebApplication, they are stored in the config database. If you have set up your farm properly in such a way... I can think of is to have another timerjob that polls some kind of queue (for example a sharepoint list in my site collection) for new timerjobs to create, and creates it if an item has been added
