Date Wed, 16 Apr 2008 06:50:21 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589437#action_12589437
] 

V.Narayanan commented on DERBY-3617:
------------------------------------

I tried a simple run without authentication enabled and and without executing any transactions

it seemed to work.

I will try this again with authentication enabled and after executing some transactions.

On the master
------------------

vn@vn-laptop:~/work/workspaces/Dery3617/master$ java org.apache.derby.tools.ij
ij version 10.5
ij> connect 'jdbc:derby://localhost:1527/replicationdb';
ij> connect 'jdbc:derby://localhost:1527/replicationdb;startMaster=true;slaveHost=localhost;slavePort=8001';
ij(CONNECTION1)> connect 'jdbc:derby://localhost:1527/replicationdb;stopMaster=true;slaveHost=localhost;slavePort=8001';
ij(CONNECTION2)>

On the slave
---------------

vn@vn-laptop:~/work/workspaces/Dery3617/slave$ java org.apache.derby.tools.ij
ij version 10.5
ij> connect 'jdbc:derby://localhost:1528/replicationdb;startSlave=true;slaveHost=localhost;slavePort=8001';
ERROR XRE08: DERBY SQL error: SQLCODE: -1, SQLSTATE: XRE08, SQLERRMC: Replication slave mode
started successfully for database 'replicationdb'. Connection refused because the database
is in replication slave mode. 
ij> connect 'jdbc:derby://localhost:1528/replicationdb;failover=true';

> 2. slave failover.
>    hangs.....
> According to "Functional Specification for Derby Replication" Rev. 9.0:
> "Failover": "... . The command is only accepted  on the slave if the network conection
with the master is down." so expecting failover to return valid Connection.
> However, failover never finish.
> See attached master and slave derby.log and testrun log.out.
