I have a Webshpere Message Broker Application which has its static DB on a remote Oracle Server.
The Oracle Server has a scheduled restart everyday.
Everytime oracle server is restarted , will the broker need to be restarted to reset the DSN connection?

I tried this locally in the development environment and Broker required a restart , just trying to understand of some setting that needs to be done at the Broker / flow level so that this can be avoided.

note :Not using any Pub Sub functionalities

WMB 6.0 , Oracle 9i, Windows platform

Hi Team,

I think if ur broker db is used only during the creation of broker , u no need to stop start the broker if u have restarted ur Database, but if u have used the database in any of the flows, u shud restart the broker to get the new connections.

I believe from MB V6 onwards the connection establishes automatically once you restart the database.

This is not a stable condition, restarting the Database every day.

In your case, a script has to be written such a way that it executes the mqsistop and mqsistart at some particular time.

No, mqsireload will do just as well.

Or a certain tolerance for "errors being thrown during and after DB restart".
