Reg : Connecting an XE database -

Question

Hi Experts,
Suppose I install Oracle XE database in my machine. Then, will my other team members (from their machines) be able to connect it and use.
Sorry, for not being able to phrase the question properly (much ignorance in this domain).
Can anybody please give me some pointers to this?
Please let me know if you need any further clarifications.
note - We are on MS Windows 7 (X86) machines.
Thanks,
Ranit B.

Answer 1

error on executing this - ... v_smtp_host VARCHAR2 (50) := '127.0.0.1'; ... UTL_SMTP.helo (v_conn, '127.0.0.1');So you're running a mailserver on localhost? Or not? That could explain the 'service not available' error.
Try pointing smtp_host to ... a host that has a running smtp service.
Back to the original problem ...
I thought might be connecting to an XE database remotely is also not possible.Yes indeed it is possible.
If your database is up, and listener running, and your firewall program is not blocking the listener port, remote database connections work just fine, if the client is correctly configured.
Configuring a client means identifying the remote database host or IP address, listener port number, and database service name.
From your XE host, you can test remote connections to your database, look at how the client is setup, usually in tnsnames.ora. Test it using a command box with:
tnsping xe
... TNS Ping Utility ... parameter files:... <client %ORACLE_HOME%>\network\admin\sqlnet.ora
Attempting to contact (DESCRIPTION=... host ... port ... service_name ...
OK (<n> msec)
# Or result can also be not OK, like:
TNS-12535: TNS:operation timed out # maybe invalid hostname, or host is offline/down
TNS-12541: TNS:no listener  # doh ... the listener is not running on that port at that host
# to verify the correct service_name:
sqlplus /nolog
connect <username>@xe
... password ... Connected.
# or not. maybe:
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect # doh client specified service_name is not correctKnow the remote database host, port, and service_name. Or the ORACLE_SID for the database instance could be used in place of service_name.
And on the database host, remote connection attempts will not be blocked by the firewall, to check if the firewall is blocking connections, a remote connect test is needed.
