Oracle Database Discussions

Hello,

I am running a Oralce 9i Database and I am trying to setup, that my client (I just have one client because I am studying for the OCP) connects to the database via TCPS.

So I set up my listener to "speak" TCPS:

TNSLSNR for Linux: Version 9.2.0.1.0 - Production
System parameter file is /u01/app/oracle/product/9.2.0.x/network/admin/listener.ora
Log messages written to /u01/app/oracle/product/9.2.0.x/network/log/listener.log
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=dbserver)(PORT=1521)))
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=dbserver)(PORT=2484)))

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=dbserver)(PORT=1521)))

Ok and I set up the tnsnames.ora file on the client this way:

DB01 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCPS)(HOST = dbserver)(PORT = 2484))
)
(CONNECT_DATA =
(SERVICE_NAME = db01)
)
)


If I am trying to connect to the db "db01" then I get the following error.[No firewall between the client and the database. I also have performed a complete installation of the Oracle software on the client and the server.[/b]

Error:
ORA_28759:Failed to open file

[b]I also get the error when I am using sqlplus when I am running sqlplus on the server and want to connect to the db "db01".

I have looked here in the forum and also in the Internet but it seems like that I am pretty much the onliest one which is having this problem.
