We are going to discuss with you the new features of DB2 V9.5 today. We all know that there is a new feature in the DB2 V9.5 database, that is, both MAX_CONNECTIONS and MAX_COORDAGENTS can be set to AUTOMATIC. If you think the system can withstand all the connections and want to limit the resources consumed by the Coordination proxy, you can set MAX_CONNECTIONS to AUTOMATIC and MAX_COORDAGENTS to a value. In this case, the system considers that the number of connections to the instance is unlimi

Here we will analyze some specific content of the PPPoE protocol. We have also studied the PPP protocol before, so we can understand PPPoE more easily. This time we will also talk about the PPPoE discovery stage. Data packets of the PPPoE protocol are encapsulated in the data domain of the Ethernet frame. Ethernet frame headers include: 1. Target MAC address (the broadcast address in this phase is ffffffffffff) 2. source MAC address client MAC address) 3. Ethernet protocol type (this stage is 0x

the database.For private sorting, the Database Manager configuration parameter sheapthres Specifies the soft limit of the total amount of memory that a private sort can consume at any point in the instance range . If the total private sort memory consumed by an instance reaches this limit, the memory allocated for additional incoming private sort requests is greatly reduced. This will see the following message in Db2diag.log: "Not enough memory available for a (private) sort heap of size size o

amplification Analysis of double buffering class time calculation problem @ (OS) An OS uses double buffering to transfer data on disk. The time it takes to transfer data from disk to the buffer is T1, and the time it takes to transfer data from the buffer to the user area is T2 (assuming T2 is much smaller than T1,T3). The amount of time that the CPU takes to process the data is T3, and the total time used
