I am doing a school project. Try to make a database application program in linux to connect remote oracle database server(LAN).

Actually, i am the newbie of the oracle database. I have downloaded the oracle 9i release 2 from Oracle.com. And i have installed the Oracle 9i client to the linux( including the client program and the Oracle Enterprise Manager). But how could i connect the remote server??

Where can i specify the IP, Server Name and User/PWD of the Oracle Database Server in the Oracle 9i Client Config.? I try to ue SQLPLUS to connect, but i can't find the place to input such info.

Also, i have installed Oracle Enterprise Manager, is it the GUI interface in Xwindow? How could i startup of it?

I have read the Oracle Admintration Guide and Installation Guide, but still don't have idea of the above questions...

Thx for ur help!!

for sqlnet connectivity use tnsnames.ora
for all thick drivers (odbc/oci/perl/pro*c) use tnsnames.ora
for JDBC thin driver, no tnsnames.ora is required.

tnsnames.ora is the client side configuration file that identifies the database server to talk to.

search this site or google for more info.

http://www.mike-devlin.com/oracle/tnsnames_ora.htm
and ofcourse, documentation

Thx for ur kindly help!!

i have created the tnsnames.ora and the sqlnet.ora under the dir /$ORACLE_HOME/network/admin/ but still can't connect the server by SQLPLUS.

it shows the error :

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory

my tnsnames.ora:

SPK =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dn2)(PORT = 1521))
(CONNECT_DATA = (SID = sp01))
)


what is the problem of it??

Also, does the tnsnames.ora file really need to be Generated by Oracle configuration tools? Can i created it by hand?

in fact, i can't set it by configuration tools during the installation process. I create it by hand only.....

thx for ur help~~
