 Doc: 125021.1 talks about firewalls.

Look for "USE_SHARED_SOCKET " to keep the dedicated connections.

> Hello all

> First a little background.

> We work with oracle 8.1.6.3.4 on NT or win2000 servers.
> The technical people have just move an application server
> behind a firewall.
> The application servers access a database that is a central
> repository of
> user connections (i.e. all applications on the intranet
> access this database
> for each page for each user). They saw that the application
> works fine for a
> while and then they get access denied. They track it down to the port
> numbers in the firewall. We are working with dedicated
> connections and it
> seems that the port numbers for each connections are climbing
> up until they
> exceeded the range of open ports in the firewall. They said

> the same problems in another server, they brought an outside
> guy (of course
> without telling the DBA group) and he solved the problem.
> They brought me
> the init.ora file of that database (I can not access it via
> the firewall)
> and showed me the parameters that made the difference. The guy put in:
> mts_dispatchers= ... port=8000) (5 dispatchers). Since they
> want me to do it
> on a central and essential database I want to ask you guys:
>
> 1) Any gotcha moving from dedicated connections to MTS?
> 2) Is each dispatcher assigned for the current sql command
> and then released
> or is it assigned for the duration of the session?
> 3) What is the ratio of users per dispatcher?
> 4) Is there a way to tell oracle to reuse port numbers for dedicated
> connections that were closed?
> 5) Anything else you care to share.
>
> Sorry if my questions are somewhat trivial but we need a
> decision tomorrow
> morning (in 18 hours) as they start doing some training session on the
> system on Sunday and time is short.
