Subject [jira] Updated: (DERBY-3254) Implement the replication failover functionality
Date Wed, 19 Dec 2007 02:31:43 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3254?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

V.Narayanan updated DERBY-3254:

    Attachment: failover_impl_notforcommit.stat

Upon receiving a failover command the following sequence will be followed

1) Stop the master
2) Flush the buffer
3) Send the failover command to the slave.
4) slave receives the failover command and performs failover.

The flush buffer implementation can be shared with the stop command implementation. Also
the stop implementation will conflict with the stop implementation as they affect the same
files. Hence I am posting a preliminary patch for now, which I hope to refine later.
