Message CPI3712 "Save-while-active checkpoint processing complete"
is sent to the message queue specified in the SAVLIB command:
SAVACTMSGQ(MYLIB/MYMSGQ)
As for reducing the time it takes to reach a checkpoint, consider using
multiple tape drives and running multiple save commands concurrently. Also
use SWA for data libraries only. Programs, display files etc. can be saved
without having to use SWA. I've also heard from a very credible source that
there is no advantage to using SWA for source files. Once you do this, your
time to checkpoint will improve significantly. I backup my entire 1.5TB
system nightly using SWA and a combination of concurrent full or cumulative
saves. My time from quiesce through checkpoint to system startup is less
than 15 minutes on average. ==================================
