Hi

I have created a db link in my backend database and a view on top of it.
developer has created an application on this view( which uses db link,) he sometime gets error saying page can not be displayed when accessing his application and at the database level we are getting plenty of trace/dump files and below error message

ORA-02097: parameter cannot be modified because specified value is invalid
ORA-00439: feature not enabled: Database resource manager

any advice is appreciated.

Thanks
