Running OEM on a UNIX Box and more (Newbie, Please Help)

Question

Hello,
This may be quite very simple for many of you. I am used to a windows environment and now have been dropped in to a Unix/Linux world. I am looking for some help in regard to:
1.) How can I start up Oracle Enterprise Manager for 10g through Unix?
2.) Can I use the something like the DB Homepage (Oracle 10g Personal Edition)?
3.) What tools are recommended, I started up SQL Developer, it seems to work, but are there any better that do similar functions?
I appreciate any help that can be offered. Thanks.

Answer 1

Thank you so much for your help.
I was able to get the Enterprise Manager to load up
on a browser. But I got an error:
Error
Io exception: Got minus one from a read call
As I tried to log in. Not sure what that mean, could
it be a privalege issue?
When I tired to emctl start dbconsole, i got a
Permission Denied error... could that also be a
privilege issue on the DB server or the Box its on?You need to do all the above while logged in as the Oracle software owner. i.e, the user that installed Oracle Server and the Enterprise Manager. This user is usually oracle if you used the default standards.
And my last question to sum up my day of
frustration.. I am trying to Link the Oracle Tables
in Microsoft Access 2003. No luck using the ODBC
provided by Mircosoft, I get an error saying:
ODBC-call failed. ORA-12514: TNS: listener does not
currently know of service reuested in connect
descriptor. You define a TNS entry in $ORACLE_HOME/network/admin/tnsnames.ora of your Oracle Client (this case Windows), then the SERVICE_NAME parameter must match the dbname.db_domain of your database. Then the TNS Servece Name you enter in the ODBC Driver Configuration must match the Net Service name in the tnsnames.ora.
Here is my example tnsnams.ora entry:
My Database Name (and SID) is TESTDB. My servername is TESTSERVER. I connect to TESTDOMAIN.COM.NG My Listener is on port 1521 (the default). Assuming I have not changed my db_domain after a default install, it will be TESTSERVER.TESTDOMAIN.COM.NG (you can find this in initTESTDB.ora or spfileTESTDB.ora of your database)
TESTDB
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = TESTSERVER.TESTDOMAIN.COM.NG)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = TESTDB.TESTSERVER.TESTDOMAIN.COM.NG)
In the above example, TESTDB should be entered or selected in TNS Service Name in ODBC Driver Configuration.
I am sorry for asking so many question, i tried my
best to refrain from it, but after a day of trying to
figure it out and downloading all kinds of things to
"fix" it, i give up. Any help would be greatly
appreciated. Thanks.My advice? Read the Enterprise Manager Documentation of your Operating System. You will find or download every Oracle Product Documentation at http://www.oracle.com/technology/documentation/index.html including that of Enterprise Manager http://download-uk.oracle.com/docs/cd/B16240_01/doc/nav/portal_booklist.htm. Once you have familiarised yourself with the basics (at least), there will be no need to hack around the problems. you will fix it :-)
