Steve,

 

Correct! A Point in Time. However, it is only providing this facility
because the IBM hardware cannot. If you are using HDS Shadowimage At-Time
split then there is no need to disrupt your DB2 processing with Log
Suspend/Resume.

 

There seems to be an impression that DB2 Log Suspend/Resume magically does
something magical with in-flight transactions. Remember the post from Phil
Steele:

 

"the only issue I see is that if you want a nice consistant database that is
already complete just like it had been shut down in an orderly manner and
didn't need any recovery at all, then a quiece before flash copy
commencement would be needed."

 

Unfortunately for Phil, DB2 Log Suspend/Resume does not do what he
described. The only way to get that pristine environment is to shutdown DB2
in an orderly manner.
