Subject [jira] Commented: (DERBY-3428) Doing a replication failover should shutdown the database and the connection should no longer be available
Date Wed, 27 Feb 2008 10:07:51 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12572852#action_12572852
] 

Jørgen Løland commented on DERBY-3428:
--------------------------------------

I tried the following:

---8<----
term1: start NS
term2: boot database '//localhost/test'
term3: shutdown '//localhost/test'
term2: show tables

ERROR 08006: A network protocol error was encountered and the connection has been terminated:
the requested command encountered an unarchitected and implementation-specific condition for
which there was no architected message
--->8------

Hence, this is the message you get when you try to do something with a connection to a database
that has been closed. It is not replication-specific. I'll open a new jira for this.

> Oystein says (as part of comments in Derby-3205)
> After executing a failover, I am told that the database is shut down, but I still able
to use the connection to access the database:
> ij version 10.4
> ij> connect 'jdbc:derby:masterDB;user=oystein;password=pass';
> ij> call syscs_util.syscs_freeze_database();
> 0 rows inserted/updated/deleted
> ij> connect 'jdbc:derby:masterDB;user=oystein;password=pass;startMaster=true;slaveHost=localhost';
> ij(CONNECTION1)> call syscs_util.syscs_unfreeze_database();
> 0 rows inserted/updated/deleted
> ij(CONNECTION1)> connect 'jdbc:derby:masterDB;user=oystein;password=pass;failover=true';
> ERROR XRE20: Failover performed successfully for database 'null', the database has been
shutdown.
