Blasadmin, not blappconf…
Hi Shermeen, run this utility and you will get the option to put new DB server
blappconf inside the installation directory,
to be more precise if APP Server is windows - a program must have been installer "Application server configuration wizrd" click on that a page will be open where you can put new DB details.
Oracle 1521, SQL 1433
If you are trying to point BSA to another DB, you can open the 'Application Server Administration Console' and using the GUI, you can select another DB values. That would be much easier. Also, stop the App server services before changing this DB values and then start the services again.
