SharePoint Cache Clearing Process in Farm

Follow the below steps to reset cache in SharePoint Farm:

• Stop the “SharePoint 2010 Timer” service.
• Delete all the XML files in the config cache. There are loads of XML files that can be found in the folder “C:\ProgramData\Microsoft\SharePoint\Config\”. Note there seems to only ever be one folder under Config which has a GUID. There are other folders which map onto this folder, but this one seems to be on every environment whereas the other locations may be found in different places on some environments. Therefore deleting the files from this folder should work in all environments.
• Edit the “cache.ini” file in the same folder that contained the XML files, setting the content to “1″ (without the double-quotes). This indicates that all cache settings need to be refreshed. Eventually this value gets automatically updated to another number when the cache is repopulated.
• Start the “SharePoint 2010 Timer” service.

Note: Require admin access.
