Oracle Listener service

I recently installed Oracle Suite (with Oracle Designer)

My problem is: I am not able to login to the database  at all. I tried sys/psw@host, scott/tiger@host. I keep getting either "TNSnames" error or a "No Listener" error. I checked my PC services. There is no Listener service present.

1. What am I doing wrong? What is the default username/password?

2. How to create an appropriate Listener service?

3. Why don't I see "database Configuration Assistant" in the list of utilities (so that I may create a DB with my own user/pwd)? Do I have to install it separately?

Try this:

1. Check the list of services (I assume U R on windows, if not give me a note.)
Look for entry starting with Oracle*.

when present go to step 3.

2. If you don't have any service named like this, you didn't installed Oracle DB Server  - look for CD Standard edition
or enterprise edition and/och check your installed packages. Install the server and retry.

3. If the services are present and running, then I would recommend checking for the file tnsnames.ora in the
oracle instalation tree under network/admin or so. This file should contain an entry pointing to the a service name
found in the list.

When you need more information, please give the version of Oracle and list of CDs you have used for installation.

my dear friend, first of all u have first install the Oracle DAtabase, then only u can install the ORacle Designer suite as designer requires database to connect.

first check in the CD kit whether u have any CD with Oracle Enterprise edition, if so then install that first and then install the designer suite.

once done then create a Connect string using net 8 easy config. copy the file from the DB path to the Designer path and then try.
