 Returns information about a page in a database.  The function returns one row that contains the header information from the page, including the `object_id`, `index_id`, and `partition_id`.  This function replaces the need to use `DBCC PAGE` in most cases.

 ## Remarks  
-`sys.fn_PageResCracker` is used to convert the 8-byte hexadecimal representation of a database page to a rowset that contains the database ID, file ID and page ID of the page. You can obtain a valid page resource from the `page_resource` column of the [sys.dm_exec_requests (Transact-SQL)](../../relational-databases/system-dynamic-management-views/sys-dm-exec-requests-transact-sql.md) dynamic management view or the [sys.sysprocesses (Transact-SQL)](../../relational-databases/system-compatibility-views/sys-sysprocesses-transact-sql.md) system view.  The primary use of `sys.fn_PageResCracker` is to facilitate joins between these views and the [sys.dm_db_page_info (Transact-SQL)](../../relational-databases/system-dynamic-management-views/sys-dm-db-page-info-transact-sql.md) dynamic management function in order to obtain information about the page, such as the object to which it belongs.

 ## Examples  
 The `sys.fn_PageResCracker` function can be used in conjunction with [sys.dm_db_page_info (Transact-SQL)](../../relational-databases/system-dynamic-management-views/sys-dm-db-page-info-transact-sql.md) to troubleshoot page related waits and blocking in [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)].  The following script is an example of how you can use these functions to gather database page information for all active requests that are currently waiting on some type of page resource.
