Subject [jira] Commented: (DERBY-4786) Shutdown command without username and password should work with mixed client and network server releases.
Date Thu, 02 Sep 2010 04:45:53 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12905400#action_12905400
] 

Lily Wei commented on DERBY-4786:
---------------------------------

+1 for send shutdown command with protocol level 2 whether there is username and password
or not. If this command fails because of protocol mismatch, then send shutdown command with
protocol level 1. If users want to shutdown the server, it should not failed because protocol
mismatch. Does people concern about security for this solution?

> DERBY-2109 introduced optional parameters username and password to the shutdown command.
But with this fix, the existing shutdown command which does not use username and password
stopped working from client with DERBY-2109 changes against a network server without DERBY-2109
changes.
> This jira is to ensure that existing shutdown command without user name and password
still works fine between different releases of client and network server(with or without DERBY-2109).
The new shutdown command introduced by DERBY-2109 will work obviosuly only on client and server
with DERBY-2109 changes. For client/server not with DERBY-2109 changes attempting to user
use name and password will get an error.
