While query CP parallelism used multi-tasking for a query within a DB2 subsystem, this method enables all the members of a DB2 data-sharinggroup to process a single query.
Scaling DB2 servers involves just adding one or more members to existing datasharinggroup.
扩展DB 2服务器涉及将一个或多个成员添加到现有数据共享组中。

CP parallelism (multiple tasks on multiple CPs) was implemented in DB2 V4. Sysplex query parallelism (multiple tasks on multiple members of a DB2 datasharinggroup) was introduced in DB2 UDB V5.
