> Dispatchers and job queue processes read tnsnames.ora on process

> of one of he sessions using that dispatcher.
>
> If you make a change to the tnsnames.ora, dispatchers and job queue
> processes won't register it unless you restart them. For job queue
> processes this is simple (alter syste set job_queue_processes = 0;
> wait for jobs to complete, then set them back to the orig. value).
>
> For dispatchers, you have to "shutdown dispatcher" (alter system
> shutdown 'Dnnn'). Then, to get it to restart, you have to run "alter
> system set dispatchers = '<foobar>';" with the COMPLETE dispatcher
> specification for the parameter index you eliminated the dispatcher
> from.
>
> This is annoyingly complex. When using multiple interfaces, multiple
> dispatcher parameter indexes and a variety of listener attributes
> within the dispatcher parameters, it can be difficult to get it right.
>
> Also, you have to do the dispatchers ONE AT A TIME so you don't block
> everyone out while you are waiting for the dispatchers to exit. TIME
> CONSUMING!
>
> Is there a way to make the dispatcher just reread the tnsnames.ora
> file without all this rigamaroll?
