Knut Anders Hatlen commented on DERBY-4196:
-------------------------------------------
Thanks for the patch, Kim. The changes look very good to me. I agree that it's
best to remove the description of the exact error message from the paragraph.
It's probably OK to leave the actual message as it is, since the
freeze/unfreeze approach is very likely to have been used if the situation
occurs.
+1 to commit.
> Document initiation of replication from cleanly shut down database

> Key: DERBY-4196
> URL: https://issues.apache.org/jira/browse/DERBY-4196
> Project: Derby
> Issue Type: Improvement
> Components: Documentation, Replication

> The admin guide describes how to start replication.
> http://db.apache.org/derby/docs/dev/adminguide/cadminreplicstartrun.html
> It describes two steps that must be performed before the database is copied
> from the master to the slave:
> 1. Boot the database on the master system
> 2. Freeze the database (CALL SYSCS_UTIL.SYSCS_FREEZE_DATABASE())
> Those two steps could be replaced with a single step:
> 1-2) Make sure the database on the master system is shut down cleanly
> This works because then there is no recovery to be performed when the
> database later is booted in master mode, and neither the log nor the database
> will be modified during boot, so the master database will stay completely in
> sync with the slave.
> Advantages with the alternative procedure are:
> - no need to keep a process running with the database booted and frozen while
> copying the database from the master system to the slave system
> - uncommitted transactions that are active at the time of the copying won't
> cause any problems (DERBY-3896)
