Configure Caching Service Page
This page enables you to add or update the system-level configuration for the Caching Service.
Note
If the High Availability feature is configured on the cluster, confirm that the Enterprise Edition (or higher) of either Windows Server 2008 or Windows Server 2008 R2 is installed on each node of the AppFabric Cache Cluster. For more information configuring High Availability on the cluster, see High Availability (Windows Server AppFabric Caching).
Configure Caching Service
Field |
Description |
Set Caching Service configuration |
Select to add or update system-level configuration of the Caching Service feature. |
Caching Service account |
Displays the Windows logon account for the Caching Service. By default, the Caching Service account is used for the Cache Service configuration provider. The Caching Service account is a member of the Administrators group, and has administrative access to the Caching Service configuration database. The default is NT AUTHORITY\NETWORK SERVICE. In the configuration wizard, you can only change the identity of the caching service if your computer is not joined to a domain. If you are using the Caching Service in a domain environment, it is recommended that you use the default account of NETWORK SERVICE. You cannot enter the service account in this text box, but must do so in the Select User dialog box that you access by clicking Change. If your computer is part of a domain, you cannot change the Caching Service account from the default of "Network Service". If your computer is part of a workgroup, you must change the Caching Service account from "Network Service". Use a local account that exists on all computers participating in the cluster and use the same password for the account on all computers. For configuration, the local account must have local administrator privileges, and can be either a built-in account or a custom account. The Caching Service account must have the right to generate security audits (granted explicitly by adding the account to the policy in the Local Security Policy dialog box) and the right to bypass traverse checking (granted through membership in the Everyone group). For more information, see Security Model for Windows Server AppFabric. |
Change |
Click to display the Select User dialog box that you use to select an account for the Caching Service account. |
Caching Service configuration provider |
Select the provider for the Caching Service configuration database, either XML to store Caching Service configuration information in an XML file on a network file share or SQL Server AppFabric Caching Service Configuration Store Provider to store Caching Service configuration information in a SQL Server database. Warning If XML is selected and the network discovery property is turned off, and you click the Browse button to select a file share for the XML provider, you will not be able to expand the Network folder in the Browse for Folder dialog box. You can, however, type in a UNC server share. To be able to expand the Network folder, you need to turn network discovery on by opening the Control Panel, selecting Network and Internet, selecting Network and Sharing Center, selecting Change Advanced sharing settings, clicking Turn on network discovery, and then clicking Save changes. |
Configure |
If you chose SQL Server AppFabric Caching Service Configuration Store Provider as the configuration provider, click Configure to create a Caching Service configuration database. |
File share |
If you chose XML Provider as the configuration provider, enter or browse to the network file share that will contain the XML configuration file. The file share must be a valid UNC path, e.g., \\server\share. Important You must manually create a network file share that is accessible to all cache servers in the cache cluster. The user account that is running the AppFabric configuration wizard must have “Owner” or “Co-Owner” permissions to the specified network file share and “Full Control” permissions to the folder at the file system level. The Caching Service must have Read/Write access to the network file share. |
Browse |
If you click the Browse button for the File share, you will be able to use the Browse for Folder dialog box to select the file share for the XML configuration provider. Select an existing folder or create a new folder, and then click OK. |
New cluster/Join cluster |
Select New Cluster if this is the first computer in the cluster. When you run Setup on subsequent computers in a cluster, select Join Cluster. The default is Join Cluster. To create or join a cluster, you need to specify the location of the configuration data (either in a database or an XML file), and then in the next page (Configure AppFabric Cache Node Page), enter the ports and set the firewall settings to unblock the services listed. When creating a cluster, you need to indicate the cluster size (the number of computers in the cluster). This enables the system to optimize memory allocation. |
Cluster size |
Select one of the following options to optimize performance based on cluster size. This setting is available only if New Cluster is selected.
Note Once this selection has been set, it cannot be changed. Note Your cluster size is not limited by this selection. You can still add or remove computers from the cluster after optimization. However, performance will only be optimized when the cluster size is within the range specified. Select a cluster size based upon the eventual number of nodes that will be in the cluster. Once you set the cluster size during configuration, you cannot change it later. If you select Small for the cluster size, the cluster will be optimized for one to five computers. If your cluster eventually grows to ten computers, the cluster will still be optimized for one to five computers. You cannot subsequently change the cluster size to Medium, in order to optimize the cluster for 6 to 15 computers. |
