[Laurence]

Hi there,

Does anyone know what's difference among "connect reset", "disconnect",
and "terminate"?
Thanks in advance,

IIRC, CONNECT RESET contains an implicit COMMIT and stops the
connection to database. TERMINATE end the process the server held open
to the client, and drops all resources. So, the best way to end a
connection is first CONNECT RESET and then TERMINATE.

I am not familiar with DISCONNECT, but i would assume it closes the
connection with an implicit ROLLBACK.

The command are explained in detail in the documentation. under
COMMANDs.

I guess Disconnect we use it with embedded SQL in a program.
DISCONNECT wont work in DB2CLP if we give directly,
we have to use CONNECT RESET or TERMINATE for coming out of the
connection...

There are quite a lot of subtly differences:

CONNECT RESET and DISCONNECT are SQL statements, TERMINATE is a DB2 command.

From the manuals:

CONNECT RESET:
==============
On type 1 connections, it disconnects and runs a COMMIT before.
http://publib.boulder.ibm.com/infoce...n/r0000906.htm

On type 2 connections, it connects to the default database. But there are a
few more options to control what happens.
http://publib.boulder.ibm.com/infoce...n/r0000908.htm

DISCONNECT:
===========
Can only be used from an application and not interactively. Also, there
must not be an UOW running at the time of DISCONNECT.
http://publib.boulder.ibm.com/infoce...n/r0000943.htm

TERMINATE:
==========
Explicitly terminates the command line processor's back-end process.
http://publib.boulder.ibm.com/infoce...e/r0001973.htm
Through that, it also disconnects from the DB2 server.
