[jira] Updated: (DERBY-3392) Performing failover on a database not being replicated should give a more meaningful error message.

["V.Narayanan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DERBY-3392?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

V.Narayanan updated DERBY-3392:
-------------------------------

    Attachment: Derby_3392_v1.stat
                Derby_3392_v1.diff

I decided to go by 1) since I felt we would not need
specific messages for each replication operation. 

I tried the following

ij>  connect 'jdbc:derby:mydb;failover=true';
ERROR XRE07: Could not perform operation because the database is not in replication master mode.
ij>

Now I get the desired message.

I request this patch to be considered for reviews and comments and of everything is OK
a commit too.

I am running tests on this patch and shall post the results of the test
runs as soon as the tests complete.

> Oystein says
> "If I do failover on a database where replication has not been started, I get the following:
> ij version 10.4
> ij> connect 'jdbc:derby:masterDB;user=oystein;password=pass';
> ij> connect 'jdbc:derby:masterDB;user=oystein;password=pass;failover=true';
> ERROR XRE21: Error occurred while performing failover for database 'masterDB', Failover attempt was aborted.
> I think I should rather get an error that says that database is not being replicated. (I get that if I try to stop replication on a non-replicated database)."
