Many administrators when they first configure SharePoint 2010 and hit a Web Application for the first time are likely to see a recurring event in the event log stating that the object cache has not been configured correctly. The specific error is as follows: Object Cache: The super user account utilized by the cache is not configured. This can increase the number of cache misses, which causes the page requests to consume unneccesary system resources . This is essentially telling you that you have missed a manual configuration step in which you need to run some PowerShell to set two accounts for SharePoint to use to access the object cache: function Set-WebAppUserPolicy($webApp, $userName, $userDisplayName, $perm) {     [Microsoft.SharePoint.Administration.SPPolicyCollection]$policies = $webApp.Policies     [Microsoft.SharePoint.Administration.SPPolicy]$policy = $policies.Add($userName, $userDisplayName)     [Microsoft.SharePoint.Administration.SPP...

What is a cache? A cache is a local, non-authoritative copy of data created and/or stored authoritatively elsewhere. Because retrieval of the data from its authoritative source is an expensive operation, instead of retrieving it freshly each time it’s needed, previous copies of the data are retained and used for subsequent needs. Reasons to avoid the authoritative operation include: * Network latency and delays . The data may be stored across relatively slow network links or require multiple intermediate hops to be retrieved. Rather than retrieving it for each request, a copy is stored nearby. An example of this in SharePoint is the BLOB cache; BLOBs from content databases are stored locally on front-end servers to avoid the need for further network trips to SQL. * User mediation required . The user may have to participate in retrieving the data, such as via authentication prompts and browser redirects. Imagine if a user had to undergo the three-legged process of WS-Federatio...

If you experience issues with WSS and MOSS timer jobs failing to complete are receiving errors trying to run psconfig, clearing the configuration cache on the farm is a possible method for resolving the issue. The config cache is where we cache configuration information (stored in the config database) on each server in the farm.  Caching the data on each server prevents us from having to make SQL calls to pull this information from the configuration database.  Sometime this data can become corrupted and needs to be cleared out and rebuilt.  If you only see a single server having issues, only clear the config cache on that server, you do not need to clear the cache on the entire farm. To do a single server, follow the steps below on just the problem server. To clear the config cache on the farm, follow these steps: 1. Stop the OWSTIMER service on ALL of the MOSS servers in the farm. 2. On the Index server, navigate to:        ...
