RE: Can't connect MTS from remote.

Thanks for the answer Stephen,

I can ping and tnsping the server, in fact my connection using dedicated server is working. But when I add initialization parameter for MTS in init.ora like I have mentioned before, the connections are always fail, looks like the listener can’t redirect connection to a dispatcher or the dispatcher accept and immediately disconnect connection?? Since from lsnrctl services command the number of established connection with dispatcher shows increment even though the connection is failed. Btw, I set my oracle on Windows 2000 environment. Any other ideas about the problem here?

Thank you all in advance.

Regards

Wendry.

Generally, 12545 means that something in the connection string for shared
environments is missing, the listener.ora, tnsnames.ora and sqlnet.ora contain conflicting parameters, or the init.ora MTS parameters do not match
the listener.ora.

I would make sure that you can ping the server remotely and that you can TNSPING the server as well. If not, your .ORA settings are inconsistent.

Thank You

Subject:	Can't connect MTS from remote.

Dear all,

II have set up MTS on my environment (oracle 8.1.6.0.0), but I can't connect through remote computers. The error is ora-12545 : target or host doesn't exists.

My init.ora regarding to MTS goes like this.

mts_dispatchers = "(PROTOCOL=TCP)(dispatchers=10)(sessions=20)"
mts_max_dispatchers = 25
mts_servers = 5
mts_max_servers = 30

I also add clause (SERVER = SHARED) on all tnsnames.ora files.

I have also tried to use 2 listener namely listener_mts which I set to port 1522, I use this especially to handle the MTS connection. So I add in my init.ora
Local_listener = mts1

And in my tnsnames.ora
mts1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server2000)(PORT = 1522))     )
    (CONNECT_DATA =

      (SERVICE_NAME = sheet.almi.net)
      (SERVER = SHARED)

    )
  )
I still can't connect to the database with message of can't establish connection for this type of server. So I omit the (SERVER = SHARED) part. I can connect, but the connection is DEDICATED instead of MTS. I know this by querying SERVER column of V$session and there's no entry on V$circuit. V$shared_servers shows 5 entry.

Is there anyone has experience like I have? Please give me some input here. Thank you all in advance.

Regards,

Wendry.
