Slave db is still in replication slave mode after failover if there was
replication load before failover.
---------------------------------------------------------------------------------------------------------
Key: DERBY-3463
URL: https://issues.apache.org/jira/browse/DERBY-3463
Project: Derby
Issue Type: Bug
Components: Replication
Environment: Trunk, svn r630806
Reporter: Ole Solberg
Fix For: 10.4.0.0
Slave db is still in replication slave mode after failover if there was
replication load before failover.
I.e. connect to slave after failover is refused. Case A) below.
(Connect to master after failover is OK.)
If however there is no replication load on master db before failover connection
to slave succeeds,
but connection to master fails(hang).
