Dag H. Wanvik commented on DERBY-4269:
--------------------------------------
In SlaveDataBase, the variable "inReplicationSlaveMode" holds the state. The
error message 08004.C.7 ("Connection refused to database '{0}' because it is in
replication slave mode") i only every issued in two locations, both inside
SlaveDataBase, in methods "setupConnection" and "getAuthenticationService".
In both cases, they test the variable inReplicationSlaveMode. Looking at the
booting (recovery) thread, the variable is reset to false ca line 317, inside
the thread SlaveDatabaseBootThread:
try {
:
bootBasicDatabase(create, params); // will be blocked
// if we get here, failover has been called and the
// database can now be connected to
inReplicationSlaveMode = false;
:
} catch (StandardException se) {
// We get here when SlaveController#stopSlave has been
// called, or if a fatal exception has been thrown.
handleShutdown(se);
}
Now, the thread is gone, but in our cae the variable is still true, so I
believe the boot must have thrown a (runtime?) exception for this to occur.
Notice we only catch StandardException, but any runetime exception would go
unnoticed and the thread would terminate.
I'll try to instrument this code to log any exceptions on derby.log before the
thread dies.
