Subject [jira] Commented: (DERBY-3254) Implement the replication failover functionality
Date Fri, 11 Jan 2008 06:27:34 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557915#action_12557915
] 

V.Narayanan commented on DERBY-3254:
------------------------------------

I will change this patch to do the following

1) Master initiates failover by sending a failover message to the slave and waits for the

   acknowledgment from the slave. (Slave will send an acknowledgement if its attempt to
   failover succeeds.)
2) If the acknowledgment is received it proceeds with failover.
3) Otherwise it continues as master without doing anything.
