Description Eike Stepper CLA 2011-02-08 13:54:40 EST 
We get more and more persistent system values like ID counters or branch counters and these values get more and more optional like ID counters for the coming client-side ID-assignment mode (UUIDs).

We need to abstract concepts like initialization, get/set, inc/dec, crash recovery, etc.
Comment 1 Eike Stepper CLA 2011-02-08 13:59:26 EST 
In the DBStore ID counter recovery after a crash requires access to the complete mapping information to scan all columns that can contain IDs. Currently this is not possible, because crash recovery takes place before the store has finished its activation phase. Hence the CDOPackageLoader of the repository package registry does not yet work at this time.

I'm investigating on ways to split the activation phase...
