To take multiple connection from a database after starting the network server
Hi,
I have started the network server and create a database named "server". I
have taken a connection
using JDBC Driver. After that tried to connection from same database using
ij tool or do its vice - versa . It gave the following error message :
com.ibm.db2.jcc.c.SqlException: DB2 SQL error: SQLCODE: -1, SQLSTATE:
XJ040, SQLERRMC:
serverXJ040.CXSDB6:E:\Derby\frameworks\NetworkServer\bin\serverXSDB6.DFailed
to start database 'server', see the next exception for details.Another
instance of Derby may have already booted the database
E:\Derby\frameworks\NetworkServer\bin\server.(server log:derby.log)
I hape that you will help me to understand the concept.
Thanks
Regards,
Sube Singh

Hi Sube,
Is it possible that you have brought up two copies of the Network
Server, listening on different ports? Connecting to the same database
through two servers would cause the error you're seeing. Granular Derby
locks (among other objects) aren't shared across servers. When the first
server opens a connection to a database, it seizes exclusive access to
all activity inside that database. That exclusive access persists until
a user explicitly shuts down the database.

Hi Sube,
What url did you use in ij to connect to the database. Is it possible that
you used the embedded url rather than network server url?
