Subject [jira] [Commented] (DERBY-4269) Failover did not succeed in 2 min.: testReplication_Local_3_p6_autocommit_OK
Date Mon, 18 Jun 2012 16:31:43 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4269?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13396009#comment-13396009
] 

Dag H. Wanvik commented on DERBY-4269:
--------------------------------------

Yes, apparently I did. Here it is for completeness.

Unfortunately, explicit synchronization breaks other replication tests. The new extra waiting
in "verifySuccessfulboot" makes the boot of the slavedatabase (minus the actual fail-over
part to make it a new master) incomplete until fail-over time, cf. the call to startPersistentService
mentioned above will now wait longer.

This makes other connection attempts to the slave hang (the service isn't started, so the
new thread tries to start it again), whereas previously a new thread returned an error indicating
that the slave was still in slave state. So, I am back to the first patch, which skips the
clearing of the properties for slave databases.
