------------------------------------------------

Hi All,

@Thiwanka: Yeah, I got it wrong !! Thanks for pointing it out !!

Sorry about that. I issued some queries in order to check what has happened after issuing
the above two shutting down commands.

ij> connect 'jdbc:derby:myDB';
ij> connect 'jdbc:derby:myDB1';
ij(CONNECTION1)> connect 'jdbc:derby:myDB';     ************to check whether I can switch
connections --> yes
ij(CONNECTION2)> connect 'jdbc:derby:;databaseName=myDB1;shutdown=true';  
ERROR 08006: Database 'myDB1' shutdown.        ************this is fine
ij(CONNECTION2)> connect 'jdbc:derby:myDB';     ************I connected back to myDB
ij(CONNECTION3)> select * from t;                           ************it was ok -->
Derby System has not shutdown ?? (Is this right?)

connect 'jdbc:derby:myDB';
ij(CONNECTION4)> connect 'jdbc:derby:myDB1';
ij(CONNECTION5)> connect 'jdbc:derby:;shutdown=true';  ***********I issued the command
to shutdown the entire system
ERROR XJ015: Derby system shutdown.                               ***********fine !!
ij(CONNECTION5)> connect 'jdbc:derby:myDB';                   ***********I tried to establish
a connection after shut downing the entire system --> This should fail right?? 
ij(CONNECTION6)> select * from t;                                         ***********But
it was successful !!

If my above assumptions are correct, this imply that the "system shutdown" was not actually
done.

Thanks !!

> When shutting down just a single database and not the Derby system, the log should print
a message that just that database was shutdown as I believe Derby is still loaded.

> ij version 10.6
> ij> run 'testMessages.sql';
> ij> connect 'jdbc:derby:wombat';
> ij> connect 'jdbc:derby:wombat2';
> ij(CONNECTION1)> connect 'jdbc:derby:wombat2;shutdown=true';
> ERROR 08006: Database 'wombat2' shutdown.
> ij(CONNECTION1)> connect 'jdbc:derby:;shutdown=true';
> ERROR XJ015: Derby system shutdown.
