number of times the server is called is proportional to the weight value.Pros: Consider the difference in server processing power3,SH original address hash : Extract the User IP, according to the hash function to derive a key, and then according to the static mapping table, the corresponding value, that is, the target server IP. The target machine is overloaded, the return is empty.4,DH target address hash : Ibid, just now extract the destination address of the IP to do the hash.Advantages: Bot

overloaded, the return is empty.4, DH target address hash: Ibid, just now extract the destination address of the IP to do the hash.Advantages: Both of the above algorithms can achieve the same user access to the same server.5, LC Minimum connection. Prioritize requests to servers with few connections.Advantage: The load on each server in the cluster is more uniform.6, WLC weighted least connection.

We set weights for each server weight, load-balancing scheduler according to the weight of the dispatch server, the server is called the number of times with the weight of the proportional.

By reading this article, you will understand each DB2 process, and when you see those processes, you will begin to understand what DB2 is doing. Note that the implementation of DB2 on Windows differs slightly from that based on Linux and UNIX environments. In Windows, there is only one process (DB2SYSC), a
