The following articles mainly describe the Distributed Management of DB2 9. In this column, we will explain the actual operation steps for performing automatic maintenance, it also describes how to use the utility to throttle if maintenance operations need to be performed when the DB2 database is processing the workload.
Preface
The adaptive utility of DB2 9's throttling system enables maintenance during busy hours.

voltage generated on the device cable is fixed. At this time, the method to reduce the common mode current on the cable is to increase the impedance of the common mode current loop. However, many engineers are confused about how to increase the impedance of common mode circuits. They often try to increase the impedance of the common mode loop by disconnecting the circuit board from the chassis, or connecting the chassis to the safe location. The results are often disappointing. These methods ar

Winter is approaching. The ant and the cricket are busy preparing their own winter food. From the beginning to the evening, the ants are busy and busy, while the cricket is leisurely and still singing.
Ant financial asked, "Why don't you hurry to prepare winter food ?"
"Didn't you hear me singing ?"
"But if you don't prepare food, you will starve to death in winter. Then you will not be able to sing ."
[Front-end performance] High-Performance rolling scroll and page rendering optimization, front-end scroll

Throttling
Throttling is not a direct instance management technology. It allows developers to limit the number of client connections that have been loaded on servers. After the throttling technology is used, once the configured value is exceeded, WCF automatically puts the calls waiting for processing into the queue and extracts them from the queue in sequence.

resizing a window or scrolling a page. If you add an event listener to the window scrolling event and the user keeps scrolling down the page quickly, your event may be triggered thousands of times within 3 seconds. This can lead to very serious performance problems.If you discuss building applications, scrolling events, window adjustment events, or keyboard events during an interview, be sure to mention debouncing or throttling as a way to improve pa
