How to Adjust the Cache Refresh Interval
The cache refresh interval defines the time period in which BizTalk Server updates the configuration of the endpoints. When you start BizTalk Server, all items in BizTalk Server administration, such as MessageBox databases, server properties, adapters, and connections to the Tracking database, are stored in the administration cache. All items in the cache are refreshed by the cache refresh interval. By default this is every 60 seconds, except for the server database connections and server properties. This means that if you change the general properties for a BizTalk group, such as the SMTP host, the changes are picked up within 60 seconds. System changes made outside the currently open instance of the BizTalk Server Administration console are not reflected until you refresh it.
The cache refresh interval is part of the BizTalk group properties.
Click Start, click All Programs, click Microsoft BizTalk Server 2009, and then click BizTalk Server Administration.
In the console tree, expand BizTalk Server 2009 Administration, right-click BizTalk Group, and then click Properties.
In the Group Properties dialog box, select the General tab. For the Cache Refresh property, type or select the time (in seconds) that all items in the BizTalk Server administration cache must wait between configuration cache refreshes, and then click OK.
Note Items involved in the refresh include the MessageBox databases, server properties, adapters, and connections to the Tracking database. Note By default, all objects in the cache are refreshed every 60 seconds, except for the server database connections and server properties.
