Bất cứ khi nào tôi nghĩ của Thống đốc sự, tôi nhận được một hình ảnh của một quý ông miền Nam cũ trong bộ đồ màu trắng với cà vạt nơ trắng. NỘI BÀI Xác định nguyên Thống đốc là công cụ thích hợp cho công việc cấu hình các nguồn tài nguyên Thống đốc giám sát thực hiện Thống đố | Whenever I think of the Resource Governor I get a picture of an old southern gentleman in a white suit with a white bow tie. Excuse me Gov nor but I d be much obliged but you could please restrict the CPU traffic so my job could run smooth. Many thanks to you sir. Why sure I d love a cold lemonade. Thank you kindly. Fitting right in with Microsoft s theme of SQL Server for the large enterprise Resource Governor is designed to limit CPU and proc cache memory for specific queries which improves SQL Server s ability to handle conflicting loads. For example a few reports pulling data from a parallelized query can tie up a normally fast order processing database. But limit those reports to 10 of the CPU the reports will take longer to run but the call center doesn t swamp the help desk with complaints. Although Resource Governor sounds like a panacea for all sorts of server performance ills it does have its limitations Sessions must be assigned to the workload group at the beginning of the session. As the DBA you can t alter the workload group of a runaway query to corral it into submission. If it s an assigned runaway session it stays a runaway session. Resource Governor requires Enterprise Edition so it can t help the organization with a single dual-core server running Standard Edition that desperately needs to control reporting queries. A poorly indexed query that is scanning a few million rows will still scan a few million rows even after its CPU has been limited by the Resource Governor. The poorly indexed query will take even longer to run its poor performance has simply been spread around so that others don t feel its pain quite so badly. The root source of the poor performance still needs to be addressed.
