Marc, Richard,

It is good that you had enough time to copy those logs in
after you started the ACTIVATE but before the Domino server
(recovery manager) needed them, and thus, the Domino server
saw them in the log directory and used them.  And so, the
Domino Server did not need to call the TDP for Domino
code to restore them. It would have been nice to be able
to copy those logs into the directory before the
ACTIVATE... but for some reason the Domino Server
does not like that.

It seems that this was an isolated case of manual
intervention causing turmoil. You may want to increase
the frequency of the log backups or add some additional
disk space to your log device so that a log full
condition does not happen on the Domino server.

TDP for Domino "log restore" (during activation with applylogs)
simply responds to the requests from the Domino server
if the Domino Server recovery manager needs a log that
is not present on the local log disk. That is, it is a
"callback" mechanism initiated by the Domino Server
recovery manager.

By the way, TDP for Domino, by default, has PREFETCH turned on...
... which means that it will always try to stay one log ahead of
what the Domino Server is asking for. It does this on a different
thread so that it can maximize performance during activation.

Thanks,

Del
