2.2.5.4 Domain Group Cache Versions Result Set

The Domain Group Cache Versions Result Set contains information about the version numbers associated with the Domain Group Map Caches on the front-end web server and on the back-end database server for the specified Site Collection. A Domain Group Map Cache contains a serialized representation of the External Groups that are members of Site Groups in the Site Collection. The version numbers in this result set can be used to determine whether the Domain Group Map Caches on the front-end web server or on the back-end database server are out of date and need to be refreshed. A special version number value of -2 indicates that the value MUST NOT be used for comparison.

When the Domain Group Cache Versions Result Set is returned, it MUST contain one row of version number data.

The Domain Group Cache Versions Result Set is defined using T-SQL syntax, as follows.
