Workspace Db2 for z/OS
Created by Guest

Improve performance for deferred ALTERs on the same object

Db2 supports 4096 partitions in one TS, we have only 2048 partitions. And we want to alter the keyrnages of all partitions. We recognized that the longer the deferred ALTER queue the slower the current ALTER. This is confirmed by development and in a kind it could be understood due to the fact that deferred ALTERs could be overloaded, and some checking must be done.
